| 00:20:40 | scanline | returns from dinner |
| 00:37:31 | GoRK | we could call the serial flash 'pants' |
| 00:37:51 | scanline | pants, eh? And break the breakfast cereal trend? |
| 00:37:55 | scanline | I want /dev/ricekrispies |
| 00:39:59 | GoRK | specialk |
| 00:40:06 | scanline | hehe |
| 00:40:19 | scanline | wonders what the difference between /dev/specialk and /dev/k would be |
| 00:42:07 | GoRK | SpaceCoaster: the sockts and volume pot come from mouser. i figured it'd be best to sell the board with the proper sockets and volume pots since you can't buy them at rat shack.... actually if we do make a few hundred of these boards, I can see just selling them as kits with all parts included |
| 00:42:40 | scanline | you'd get quantity discounts from mouser :) |
| 00:43:00 | GoRK | even with no quantity discounts it's still hellua cheaper than rat shack |
| 00:43:22 | GoRK | if you had to spend $15-$20 to buy the kit you'd save money |
| 00:43:26 | scanline | rat shack is only good for when you have 1 or 2 parts to get, and the difference in price wouldn't make up for S&H |
| 00:44:22 | Sammy | Morning All :-) |
| 00:44:28 | scanline | morning sammy |
| 00:44:52 | Sammy | morning scanline :) |
| 00:44:59 | GoRK | i need some press n peel so i can prototype one of these beasts and make sure my holes are in the right spots, big enough, and that i get no crosstalk, humming, etc |
| 00:50:01 | GoRK | we need to find out soon about this ucb1200 telecom codec.. if we can use it for audio or not |
| 00:50:21 | scanline | is no driver guru... |
| 00:50:31 | scanline | any driver gurus here? ;) |
| 00:50:48 | MicroChip32 | i might be if i could only learn c |
| 00:50:56 | Tangent | scanline : I can drive, and I head my own cult.... will I do ;) |
| 00:51:06 | GoRK | SpaceCoaster: also ...do you forsee anything in wheaties' future that might make the driver nicer? :) audio is wrecked by wheaties currently |
| 00:51:17 | scanline | Tangent: hehe. I don't drive, (no car) but I could start a cult... |
| 00:51:42 | MicroChip32 | drives ... his family up walls =) |
| 00:51:44 | scanline | not just wheaties... the touchscreen wrecks sound too |
| 00:52:06 | scanline | When you touch the screen, it almost sounds like an electric discharge |
| 00:52:17 | MicroChip32 | well if ya wouldnt dump your cereal into the speaker id think it would sound better |
| 00:56:34 | GoRK | hopefully the new ucb1200 driver fixes a lot of that |
| 00:56:57 | scanline | hopefully |
| 01:04:51 | SpaceCoaster | GoRK: the wheaties driver will play nice in the future, it acquires a lock around the messages and has 0.1msec delay per byte all of that can go when I implement a write queue. |
| 01:05:07 | GoRK | SpaceCoaster: good!! that is perfect |
| 01:05:40 | GoRK | we are on 2.4.7-rmk3 right? |
| 01:06:28 | SpaceCoaster | GoRK: yeah it doesn't matter how slow we write to the DSP, (the interface is self clocked) so writing a byte a time with a timer should do the trick. |
| 01:07:23 | GoRK | it might also help to use mmapped audio ... should reduce cpu usage considerably |
| 01:08:25 | GoRK | also ... i saw some stuff on using sa1100 as a usb controllerin rmk's notes.. anyone know what's up witht hat? |
| 01:08:30 | GoRK | hat/that |
| 01:10:25 | GoRK | Russ: hey it shows here that jffs2 as of 2.4.9-ac9-rmk2 has some changes in it that aren't in the MTD CVS tree. could that be the cause of some of our jffs2 problems now? |
| 01:11:07 | SpaceCoaster | GoRK: the ucb1200 is at the other end of a fifo, (8 or 12 bytes), what data rate is the audio? |
| 01:11:55 | GoRK | spacecoaser: i believe we can actually get it outputting 44.1khz 16 bit mono |
| 01:12:14 | GoRK | SpaceCoaster: without tuxphone running it sounds very good |
| 01:12:23 | GoRK | on external speakers anyway |
| 01:14:47 | GoRK | SpaceCoaster: we really need to get to the new kernel since all this ucb1200 junk has changed |
| 01:15:54 | Hiraghm | ? |
| 01:16:28 | SpaceCoaster | I will get my audio bits in three days so this weekend I will have a go at hacking wheaties to play nice. |
| 01:18:43 | SpaceCoaster | It's a pity that you can register projects at mouser (or similar) so that someone could order all the bits in one shot. |
| 01:18:50 | SpaceCoaster | s/can/can't/ |
| 01:24:31 | GoRK | SpaceCoaster: did you order parts from mouser?!? |
| 01:24:41 | GoRK | SpaceCoaster: that pcb doesnt really work yet |
| 01:24:50 | SpaceCoaster | GoRK: not recently, why? |
| 01:24:51 | GoRK | well the only thing that doesnt work is audio in/mic in |
| 01:25:04 | GoRK | SpaceCoaster: oh i thought you meant for shanip2 |
| 01:25:41 | GoRK | anyway i figured it'd just be easiest to sell the boards and all the parts as a kit so you didnt have to fool with trying to find parts |
| 01:25:49 | SpaceCoaster | well I ordered some bits from radioshack so I could play too. |
| 01:27:43 | GoRK | ah ha |
| 01:27:53 | GoRK | good deal |
| 01:29:16 | SpaceCoaster | need to get the wheaties driver quiet before trouble makers like Hiraghm and MicroChip32 get their hands on it :-) |
| 01:29:51 | MicroChip32 | huh? trouble makers? **eyes SpaceCoaster with an evil gleam** |
| 01:33:08 | MicroChip32 | id be dangerous if i knew enough c to say beans, but since i dont, i think the kernel and drivers are probably safe. |
| 01:34:08 | Tangent | MicroChip32 : I don't know enough C to say beans, but I still consider the hardware drivers to be a valid target... |
| 01:34:23 | MicroChip32 | Tangent: lol, ut oh |
| 01:34:51 | Tangent | MicroChip32 : Amazing what you can acheive with a little cut and pasting ;) |
| 01:35:20 | MicroChip32 | Tangent: yea, but then what do you do when it segfaults and produces smoke ? |
| 01:36:23 | Tangent | MicroChip32 : Solder on a new chip, revert back to the old code, and try again ;) |
| 01:36:51 | MicroChip32 | Tangent: lol, unstopable eh ? :) |
| 01:37:12 | MicroChip32 | id absolutely LOVE to know c and then get my hands on the hardware specs. id have a ball writing my own stuff from the boot loader up |
| 01:37:25 | Tangent | MicroChip32 : It's a personal philosophy never to let the fact that I don't know what I'm doing stop me from trying anyway, and maybe learning something |
| 01:37:57 | MicroChip32 | maybe i should do it in assembly, which i ~do~ know (altho for the x86 and a couple other oddballs) |
| 01:38:29 | MicroChip32 | Tangent: i do the same, but i usually drive the experts nuts with questions first ;) |
| 01:38:54 | MicroChip32 | reduces the chance of making a messy cloud |
| 01:39:02 | GoRK | when you let the smoke get out, you must collect it so that you can put it back in later. |
| 01:39:32 | MicroChip32 | GoRK: thats what ive been told, but ive never been able to collect enough of the smoke to make the chips work again. =( |
| 01:39:57 | GoRK | yeah you really have to work on getting it all |
| 01:40:45 | MicroChip32 | remembers his first smoked chip ... 386 keyboard bios ... nice little hole in the middle, stunk up the whole college dorm =) |
| 01:41:14 | Tangent | MicroChip32 : I can understand written C code (mostly)... but can never remember the syntax and stuff like that... I'm pretty good now at taking someone's code, and bastardising it to do what I want |
| 01:41:54 | MicroChip32 | Tangent: i know the very basics, but pointers and strings in c drive me nuts |
| 01:42:19 | Tangent | MicroChip32 : I hate pointers.... |
| 01:42:37 | MicroChip32 | Tangent: pointers are fine, as long as they arent in c |
| 01:43:00 | Tangent | MicroChip32 : I'm much more like... Hrm.. the error says.. .eth0: timeout doing thingy... search the source for thingy timeouts, and tweak them around... |
| 01:43:22 | Tangent | MicroChip32 : Pointers are scary things |
| 01:43:51 | MicroChip32 | Tangent: no pointers are usefull and fun ... just not in c =) [ assembly is cool <G> ] |
| 01:44:20 | Tangent | MicroChip32 : Assembly is cool.. I have to agree |
| 01:44:32 | MicroChip32 | my preferred language these days is perl tho |
| 01:44:52 | MicroChip32 | if i could only figure out why its eating up 50 megs of ram to process a 3 meg file ... |
| 01:45:12 | Tangent | MicroChip32 : I don't really have a preffered language.. I'm dangerously ignorant in all of them |
| 01:45:29 | Tangent | MicroChip32 : At the moment, I've been doing PIC microcontroller coding.. |
| 01:45:46 | Tangent | MicroChip32 : I may get to do some OCCAM coding again one day soon.. or something very similar :) |
| 01:46:00 | MicroChip32 | Tangent: heheheh off the top of my head i can only think one common language that i know nothing about, and thats fortran |
| 01:46:18 | MicroChip32 | next in line is c |
| 01:46:32 | Tangent | MicroChip32 : Yeah.. I never really touched fortran.. or modula2 |
| 01:47:15 | MicroChip32 | assembly, pascal, c (sorta), cobol, rpg, vbasic, javascript, java, html, perl |
| 01:47:46 | MicroChip32 | and a few off-the-wall-custom-purpose ones. |
| 01:48:56 | MicroChip32 | i really need to get my hands on a good c tutorial book, then get my hands on a kernel/driver how-to linux book |
| 01:49:10 | Tangent | MicroChip32 : occam, miranda, pascal, perl, c, c++, 6502, 68k, PIC ASM, VHDL |
| 01:49:16 | GoRK | gotta eat bbiaw |
| 01:49:20 | MicroChip32 | 6502 is cool |
| 01:49:54 | MicroChip32 | **wondering where Tangent encountered 6502** |
| 01:50:33 | Tangent | MicroChip32 : I had a C64 whenI was younger... and have since built a 6502 board (which is currently broken) |
| 01:50:39 | ProtWork | 6502... old processor. |
| 01:50:52 | MicroChip32 | 6502 derivitives are still in active use |
| 01:50:55 | ProtWork | wow, Occam. That's one I haven't seen in a long time. A transputer fan, perhaps? |
| 01:51:00 | Tangent | Was doing 6502 code when I was 13 years old :) |
| 01:51:12 | Tangent | ProtWork : Yeah.. .I got on really well with transputers |
| 01:51:30 | ProtWork | Tangent: Wow. Are they doing anything anymore? |
| 01:51:38 | ProtWork | I thought those were definately cool. |
| 01:51:39 | Tangent | ProtWork : Occam was the easiest language I ever learned.. It was all like digital electronics |
| 01:51:42 | MicroChip32 | hehe, met my first computer at 12. apple II |
| 01:52:08 | Niddix | I still remember my first. TRS-80 Model 1 |
| 01:52:10 | Tangent | http://wotug.ukc.ac.uk/parallel/occam/projects/occam-for-all/kroc/ |
| 01:52:18 | Tangent | I went to the University of Kent BTW |
| 01:52:32 | ProtWork | Damn. |
| 01:52:39 | ProtWork | Occam was so sweet. |
| 01:53:27 | Tangent | ProtWork : I want an Occam style thing for my Home Automation stuff... Here's my plan for temperature control for my server room... http://ipaq.secret.org.uk/HomeAutomation/EventModule.pdf |
| 01:53:50 | Tangent | ProtWork : Spot the similarity to Occam stuff :) |
| 01:54:59 | ProtWork | Ack, we're having massive routing problems here. |
| 01:55:29 | MicroChip32 | ProtWork: i think youre not alone, ive been disconed several times today, and it wasnt my isp |
| 01:59:38 | MicroChip32 | well guys (and gals if any), im off to bed. catch ya'll on the flip side |
| 01:59:50 | Tangent | MicroChip32 : Yeah.. I'm off too... |
| 01:59:51 | Tangent | Night |
| 02:00:04 | MicroChip32 | we knew YOU were off Tangent :) |
| 02:00:15 | MicroChip32 | g'nite |
| 02:00:16 | Tangent | MicroChip32 : Oh thank you :D |
| 02:00:28 | MicroChip32 | welcome ;) --out-- |
| 03:35:23 | Hiraghm | university of Kent.. isn't that in England? |
| 03:36:11 | Hiraghm | (sorry, I was afk a long time 8c) |
| 05:29:49 | Russ | ok, building 2.4.13-ac5-rmk2-tux1 |
| 05:31:03 | andersee | Russ: progress? |
| 05:31:15 | Russ | dunno, easy merge |
| 05:31:35 | andersee | easy merge is goof |
| 05:31:38 | andersee | easy merge is good |
| 05:31:39 | andersee | heh |
| 05:39:25 | Russ | you can give that a try |
| 05:39:39 | Russ | mine's still compiling |
| 05:40:47 | andersee | k, thx |
| 05:43:21 | GoRK | lalala! |
| 05:43:58 | GoRK | go, kernel, go |
| 05:44:26 | scanline | GoRK: I'm tired of debugging text code, thought I'd try some alpha blending :) |
| 05:44:54 | GoRK | scanline: what ever happened to that last remaining dialog buglet? did that get stomped? |
| 05:45:22 | scanline | GoRK: not yet.... I know where it is kinda |
| 05:45:31 | scanline | it happens on x86 also |
| 05:46:48 | Russ | grrr.... |
| 05:46:50 | Russ | same thing |
| 05:47:26 | GoRK | Russ: did you see about the jffs2 merges that rmk did that did not get applied in the mtd cvs? |
| 05:47:47 | Russ | no, shouldn't it be fixed by now? |
| 05:47:50 | GoRK | some freaky optimizations |
| 05:48:08 | GoRK | Russ: i dunno... what does running a jffs or cramfs root do? does it remount properly? |
| 05:48:35 | Russ | don't know |
| 05:48:59 | GoRK | it was quite a while ago .. the note about the jffs stuff |
| 05:49:04 | GoRK | maybe those can be turned off |
| 05:49:17 | Russ | I'm up to 2.4.13-ac5-rmk2 now |
| 05:49:35 | GoRK | except for the jffs2 right? |
| 05:50:13 | GoRK | i mean that's all that seems to be broken? |
| 06:04:36 | Russ | ya |
| 06:04:47 | Russ | except for some pcmcia "changes" |
| 06:04:59 | Russ | also, its a new ucb1x00 driver |
| 06:05:01 | GoRK | is your diff posted on your site? |
| 06:05:11 | Russ | lemme copy this diff |
| 06:05:41 | Russ | there |
| 06:05:47 | Russ | patch-2.4.13-ac5-rmk2-tux1 |
| 06:06:55 | GoRK | did you make one of these keys on this kbd sysrq ? is there a way to use sysrq on the tux? |
| 06:20:31 | GoRK | lala compile.... |
| 06:28:02 | GoRK | haha the crossover plugin is awesome |
| 06:28:16 | GoRK | i havent used wine in a while |
| 07:16:47 | GoRK | ooh dhcp in the kernel :) |
| 07:28:37 | GoRK | hrm we could tie to the sa1100 ssp port and use our own dac |
| 07:28:41 | GoRK | anyone still here? |
| 07:29:07 | scanline | GoRK: i'm still awake (no surprise there :) |
| 07:29:28 | GoRK | scanline: apparently the new ucb1200 driver has telecom support.. |
| 07:29:36 | scanline | ooh! |
| 07:29:52 | scanline | cracks whip, makes GoRK get it working on the Tux |
| 07:29:55 | scanline | hehe |
| 07:30:08 | scanline | so there are jffs2 issues with the new kernels? |
| 07:30:23 | GoRK | scanline: also we could theoretically get another sound device with a second hardware modification itself... if there isnt something on the ssp port already anyway |
| 07:30:49 | scanline | heh. cool |
| 07:30:57 | scanline | is that on the ucb1200 or the sa1100? |
| 07:31:13 | GoRK | sa1100 |
| 07:31:26 | scanline | ok |
| 07:31:39 | GoRK | the LART has a dac directly attached to the ssp port of sa1100 and there is now an audio driver for it |
| 07:32:50 | scanline | hey, cool |
| 07:33:11 | scanline | so 1 chip and a bag of R's and C's, and we have a second line out and phones out :) |
| 07:33:21 | scanline | quick, add that to the shanip2 board |
| 07:33:46 | GoRK | probably we can get stereo no problem |
| 07:33:52 | scanline | neato |
| 07:36:18 | GoRK | a->state.input_dma = ucb->mcp->dma_telco_rd; |
| 07:36:18 | GoRK | a->state.input_id = "UCB1x00 telco in"; |
| 07:36:18 | GoRK | a->state.output_dma = ucb->mcp->dma_telco_wr; |
| 07:36:19 | GoRK | a->state.output_id = "UCB1x00 telco out"; |
| 07:36:25 | GoRK | yup!!! |
| 07:36:41 | scanline | wow |
| 07:36:55 | scanline | so is there a separate device node, or is it an ioctl() thing? |
| 07:37:32 | GoRK | looking |
| 07:41:23 | GoRK | ahh wait the ucb1200 audio uses the sa1100 audio stuff.. guess we cant do that after all |
| 07:41:42 | GoRK | maybe.. dunno |
| 07:41:46 | scanline | ah |
| 07:41:59 | GoRK | not familiar . stabbing in dark ... can't .... reach ........................................... bat belt...... |
| 07:42:00 | scanline | the ucb1200 uses a SIB bus right? |
| 07:42:05 | GoRK | yes |
| 07:42:13 | GoRK | still probably can do something on ssp if it's not taken |
| 07:42:23 | scanline | hopefully |
| 07:46:15 | GoRK | hrm i wonder if spacecoaster's problems with jffs2 on serial flash were because he wasnt using the mtd block device |
| 07:55:30 | | "Da sky" |
| 07:55:30 | GoRK | Russ: still up? |
| 07:55:38 | | Sorry, GoRK, I'll keep my mouth shut. |
| 07:55:38 | GoRK | ibot shut up |
| 08:02:44 | cory | heh |
| 08:03:12 | cory | my resident assistant just accused me of things I didn't do |
| 08:03:52 | GoRK | yes but would it have been worth it if you did do it? |
| 08:03:59 | cory | not really |
| 08:04:07 | cory | put honey and shaving cream on his door.. |
| 08:04:10 | cory | ooh, I'm cool now |
| 08:04:44 | scanline | cory: ah, more dorm dwellers :) |
| 08:05:00 | cory | heh |
| 08:05:04 | cory | I just opened my door to check out a noise |
| 08:05:05 | cory | look left, look right |
| 08:05:11 | cory | then I see him staring me back, cleaning up his door |
| 08:05:14 | cory | I can't talk to him now |
| 08:05:19 | cory | he's in a neurotic low sleep state |
| 08:05:24 | scanline | how'd he figure you did it? |
| 08:05:37 | cory | I'm in a extreme low sleep state but I am being honest |
| 08:05:56 | GoRK | gah jffs2 does do a total freakout :) |
| 08:05:57 | cory | I admit I have not done exactly what I have done tonight but I have not done what he has accused me of nor have I tried to spite him |
| 08:06:01 | cory | or take advantage of him |
| 08:06:06 | cory | I want my good name back |
| 08:06:10 | cory | anyways. |
| 08:06:21 | cory | scanline: 1. the shaving cream bandits do their work |
| 08:06:33 | cory | 2. loud noise is made on his door so he'll check their artistry |
| 08:06:34 | GoRK | maybe i shouldnt have set debug to such a high value |
| 08:06:42 | cory | 3. he checks it, stays out in the hall for a while |
| 08:06:56 | cory | 4. I hear a noise outside, it's a friend coming home with some other friends |
| 08:07:28 | cory | 5. I decide on a whim to throw away some cardboard crap in the lobby |
| 08:07:43 | cory | I don't want to flatten it or anything so I go there for the big trash can, not my dinky ones |
| 08:07:57 | cory | then, I come back, and he is watching and interprets me as coming back to the scene of the crime |
| 08:08:12 | scanline | lousy RA? |
| 08:08:13 | cory | I decide that since I am innocent I can do what I please so I go into my friend's room (after being beckoned) |
| 08:08:25 | cory | shit, scanline, the kids on my floor are being real dicks to him though |
| 08:08:39 | cory | it's a vicious circle, he doesn't tolerate ANY shit, not even mostly innocent pranks |
| 08:08:42 | scanline | yeah... RAs usually get a lot of crap |
| 08:08:47 | cory | and they get indigant and don't care and do more shit |
| 08:09:02 | scanline | hmm |
| 08:09:13 | cory | anyway I go there, he sees that as me escaping him and calls me out, chews me and another dude out, neither of us had anything to do with it |
| 08:09:18 | cory | but we knew full well who did it |
| 08:09:25 | cory | but my ra said.. "I don't care who did it" |
| 08:09:25 | cory | *sigh* |
| 08:09:30 | cory | threatens calling in the police |
| 08:09:37 | scanline | our RA here is ok. He rightly gets pissed quite a bit though... people disssembling the showers, vomiting on the floor after drinking too much... |
| 08:09:37 | cory | says his job is more important than anything else |
| 08:09:50 | cory | basically we are made for each other, haha |
| 08:09:59 | cory | I am not a good liar or a good truth teller even |
| 08:10:09 | cory | my lies don't pass muster and my truth looks like lies to people |
| 08:10:10 | cory | heh |
| 08:10:16 | scanline | heh |
| 08:10:32 | cory | I don't lie very much, I try not to lie at all, but blah.. I appear to lie a lot since I try to be honest |
| 08:10:35 | cory | </verbose> |
| 08:10:38 | scanline | The RA here thinks I'm boring since I spend most of my time programming :) |
| 08:10:48 | cory | I want to talk to him for a long while about this |
| 08:11:56 | cory | because, I think both of us understanding that I am not what he thinks I am would be better than people getting arrested etc etc the rest of the year sucking |
| 08:12:37 | scanline | yeah |
| 08:12:42 | scanline | cory: do you have a tuxscreen? |
| 08:12:58 | cory | scanline: alas, no, but I intend to get one |
| 08:13:12 | scanline | they're really neat, you will be happy :) |
| 08:13:22 | cory | yeah, everything I have seen is cool |
| 08:13:42 | scanline | soon it will even have a web browser that works under linux |
| 08:13:58 | scanline | and IRC client maybe... |
| 08:14:05 | cory | hehe, what is it called, netcat? ;) |
| 08:14:06 | scanline | (well, without a microdrive or NFS) |
| 08:14:16 | scanline | yeah, we have netcat :) |
| 08:14:31 | cory | (the web browser) |
| 08:14:32 | scanline | netcat is a web browser, MP3 player, backup system, file delivery service, and more |
| 08:14:38 | cory | hehehe |
| 08:18:17 | GoRK | well jffs2 sucked ... time to try a jffs fs |
| 08:18:46 | scanline | jffs2 is so cool :) I should try to get it working on the Helio some day... |
| 08:18:56 | cory | I think I'm going to try and sleep for 90 minutes and then go for another 10 hours |
| 08:22:20 | scanline | finds out that drop shadows really suck at 8bpp |
| 08:27:52 | GoRK | jffs bit it too.. i dont think this is a fs issue |
| 08:31:49 | GoRK | gotta sleep... nite |
| 08:32:00 | scanline | 'night GoRK |
| 09:00:35 | rfbrown | Hello all, I have a vague idea that there is a problem with resetting PCMCIA cards, but I'm looking on the wiki and can't find the details... can anyone give me a pointer? |
| 09:02:12 | scanline | is away: sleep |
| 09:12:25 | GoRK | rfbrown: the reset isnt connected to anything :) thus it is impoossible to perform a reset |
| 09:12:44 | GoRK | anyway i was supposed to be asleep |
| 09:12:47 | GoRK | so ... goodnight :) |
| 09:12:56 | GoRK | the reset pin that is |
| 09:17:06 | rfbrown | GoRK: You were going to be asleep AGES ago! Be off with you! ( I'm just confused because the schematics seem to show the PC-Card RESET pin connected to a voltage supervisor. |
| 09:17:47 | rfbrown | Where is that GPSFan when he's needed? |
| 10:25:13 | Tangent | wakes up |
| 11:30:18 | RedBaron | Good afternoon everyone |
| 11:32:41 | Tangent | RedBaron : Good afternoon :) |
| 11:33:11 | RedBaron | Tangent: :) How has it been going? I havent been around lately. |
| 11:33:43 | Tangent | RedBaron : Well.. there's a working 5V pcmcia hack now... and another hack for audio.. |
| 11:33:56 | Tangent | RedBaron : And you can add an extra serial port too (untested as yet) |
| 11:33:59 | RedBaron | Tangent: Sweet! |
| 11:34:12 | MicroChip32 | Tangent dont forget the unused usb port |
| 11:34:15 | Tangent | RedBaron : I have intimate with X etc... running on my iPAQ |
| 11:34:25 | Tangent | Yeah.. and the unused USB port :) |
| 11:34:32 | RedBaron | Kewl |
| 11:34:34 | SpaceCoaster | Tangent: don't forget about 32Mbyte support and working serial flash |
| 11:34:44 | Tangent | I forgot them :) |
| 11:34:52 | MicroChip32 | and at least one person has built the jtag adapter completely inside the tux, as i also plan to do |
| 11:35:04 | Tangent | SpaceCoaster : In fact I didn't actually know about the working serial flash |
| 11:35:14 | RedBaron | MicroChip32: Nice |
| 11:35:16 | SpaceCoaster | Russ is working on a 2.4.13 port and a new version of blob is around the corner. |
| 11:35:43 | RedBaron | SpaceCoaster: Cool. Very cool |
| 11:35:50 | SpaceCoaster | RedBaron: welcome back |
| 11:35:59 | MicroChip32 | and im considering using the 2nd serial to build a smart-card reader/programmer into it. all kinds of neat uses for custom smart-cards |
| 11:36:04 | RedBaron | SpaceCoaster: So the 32M support you mentioned...is that a 32M sodimm or 32M total_ |
| 11:36:29 | MicroChip32 | RedBaron: 32m sodimm, working on being able to use the internal 8m with it too for total 40m |
| 11:36:36 | RedBaron | SpaceCoaster: Thanks. Its been a very busy couple of weeks for me. :) |
| 11:37:46 | RedBaron | So how is the audio hack going_ |
| 11:38:09 | RedBaron | Ack. Darn danish keyboards. Everything is in weird places. Like a ? is a _. :) |
| 11:38:33 | MicroChip32 | RedBaron: try using one of those devorak keyboards ;) |
| 11:39:06 | RedBaron | MicroChip32: hehe. No thanks. :) I have to use the danish keyboard, seeing as Im in denmark right now. |
| 11:39:10 | SpaceCoaster | Tangent: have you built an audio board yet? |
| 11:39:11 | MicroChip32 | better yet, take and map out your normal keyboard as if it was a devorak <G> |
| 11:39:46 | Tangent | SpaceCoaster : Haven't made it yet.. I did a PCB layout a couple of days ago... I was just discussing making it with someone here now.. :) |
| 11:40:24 | SpaceCoaster | Have you seen the latest layout from GoRK/ |
| 11:40:39 | SpaceCoaster | RedBaron: / == ? |
| 11:40:50 | RedBaron | Tangent: So what is this audio hack? adding on an audio chip somehow or is it something else? |
| 11:41:18 | Tangent | RedBaron : I's about 6 resistors, and 5 capacitors that need adding inline with the handset connection |
| 11:41:37 | Tangent | RedBaron : No transistors.. no chips... just R & C |
| 11:41:51 | RedBaron | SpaceCoaster: / is the shft key and the 7 key. ? is the shift key and the + key. hehe. |
| 11:41:59 | RedBaron | Tangent: Ah cool. |
| 11:42:18 | SpaceCoaster | http://www.blurbco.com/~gork/tuxscreen/shanip2-gork6.gif |
| 11:43:39 | SpaceCoaster | RedBaron: yeah did a project with italian keyboards once, the boot prom didn't have the mapping so when the machine crashed you had to not look, just remember where they would be on a US keyboard. |
| 11:45:14 | RedBaron | SpaceCoaster: Mmm..fun. The danish keyboards arent terribly bad. the letters are all in the same place. its just the symbols that all moved. because they have 4 extra letters. Which means typing my password to log into my machine at home was a real pain in the rear. :) |
| 11:46:24 | SpaceCoaster | italian keyboards are AZERTY |
| 11:46:42 | RedBaron | SpaceCoaster: Huh. okie. |
| 11:47:43 | SpaceCoaster | RedBaron: we do some work for a Danish company, Systematic, know them? |
| 11:48:04 | MicroChip32 | ms keyboards are QWERKY ... s/K/T/ |
| 11:48:29 | RedBaron | SpaceCoaster: I think Ive heard of them. Im just in denmark visiting my girlfriends family. She is danish. |
| 11:49:24 | Tangent | SpaceCoaster : Ah.. just noticed that you did a PCB layout too :)... Very nice... |
| 11:49:45 | Tangent | SpaceCoaster : I didn't bother with the audio jacks on mine |
| 11:49:53 | SpaceCoaster | Tangent: not me, gosh no, Gork and GPSFan!!! |
| 11:50:43 | Tangent | http://ipaq.secret.org.uk/piccies/TuxScreen/shanip232.pdf |
| 11:50:45 | MicroChip32 | can anyone answer a couple c questions for me |
| 11:50:50 | Tangent | Here's one I prepared earlier :) |
| 11:50:56 | RedBaron | MicroChip32: Sure. shoot |
| 11:51:14 | MicroChip32 | RedBaron: can i msg you, rather than clutter the chan ? |
| 11:51:22 | RedBaron | MicroChip32: Certainly |
| 11:52:06 | SpaceCoaster | Tangent: cool, audio and RS232. |
| 11:52:25 | Tangent | SpaceCoaster : Yep.. I may have to add USB too :) |
| 11:52:49 | Tangent | SpaceCoaster : Still have to pull a tux apart, and make sure that there's space for this board |
| 11:54:16 | SpaceCoaster | Tangent: what do JP5 and JP6 connect to? |
| 11:54:44 | Tangent | SpaceCoaster : Heh.. I'm still not entirely certain about that... maybe the details are on erire.com |
| 11:56:05 | Tangent | SpaceCoaster : It appears that the 8 pin header goes to the handset socket |
| 12:18:46 | RedBaron | Tangent: So how big are these audio boards going to be? I wonder if I'll be able to fit one into my webpad'ified tux. |
| 12:37:59 | Tangent | RedBaron : You should be able to fit one in to your webpad |
| 12:38:24 | Tangent | RedBaron : The board I designed is pretty small |
| 12:38:52 | MicroChip32 | webpad'ified? |
| 12:40:04 | RedBaron | Tangent: Cool...so it would fit in the gaps left by the offset mainboard and the commboard? |
| 12:41:00 | RedBaron | MicroChip32: Yes. I'm working (well, I did some work then stopped for a couple of weeks cause of that nasty thing called RL) on ripping the guts out of my tuxscreen and turning into a mobile webpad. |
| 12:41:51 | MicroChip32 | RedBaron: sweet |
| 12:42:14 | RedBaron | MicroChip32: The tux draws on the order of about a single watt of power, with the screen on and no pcmcia cards in it. which is almost nothing powerwise. I'm still impressed it drew so little power. |
| 12:43:19 | Tangent | RedBaron : The power consumption is very important for me too.. I don't plan on running my Tux from the mains.. |
| 12:43:31 | Tangent | RedBaron : I still have to make a suitable power supply tho' |
| 12:43:35 | mallum | RedBaron: do you plan on making it have its own rechargable battery ? |
| 12:44:38 | RedBaron | Tangent: Ah. I measured the current draw when I made my voltage regulator for my battery setup. both the 5V and the 3.3V regulators drew a total of .3A. I didnt get around to measuring each one individualy. |
| 12:45:11 | RedBaron | mallum: Yes. I havent decided what type of batteries to use yet though. thats the next step. then after that I get to build acase for it all |
| 12:45:21 | Tangent | RedBaron : I've got 103 watts of solar panels and a 90AH deep cycle battery... I just need to efficiently convert from 10.8-14v down to 5v+3,3V |
| 12:45:51 | MicroChip32 | RedBaron: forget the case, build it into your dashboard ;) |
| 12:46:01 | RedBaron | Tangent: the regulators I used would work great on that. they are ...umm...what the heck brand name was it... |
| 12:46:51 | RedBaron | Tangent: they are the switching type of dc/dc regulator. not the resistive drop ones. Power Trends, which is now owned by Texas Instruments |
| 12:47:17 | RedBaron | MicroChip32: Nah. I want to make it a portable I can carry around with me. :) |
| 12:47:38 | MicroChip32 | RedBaron: ah |
| 12:47:40 | RedBaron | Tangent: They can take 7V up to around 30V I think |
| 12:47:43 | Tangent | RedBaron : I've got some other bits of power to design yet.. like the 10.8-14V to 12.00V @10A regulator... |
| 12:48:42 | RedBaron | Tangent: I dont think you would need that for the tuxscreen if you used the two regulators I used. But if you have anything else needing power... |
| 12:49:58 | RedBaron | Tangent: And 12V at 10A would be overkill for a tuxscreen I think :) even with some pcmcia cards in it. |
| 12:50:02 | Tangent | RedBaron : Yeah.. I've got plenty of other things that need power... Not to mention.. I need to make an very intelligent battery charger too.. I think the Tux is the only one that needs 3.3V power tho' |
| 12:50:31 | RedBaron | Tangent: Okay. I'm looking for the datasheet that had those regulators I used. I'll give you the link in a sec |
| 12:50:53 | Tangent | RedBaron : Thank you |
| 12:52:00 | RedBaron | Tangent: http://info.digikey.com/T013/V5/336-338.pdf |
| 12:53:36 | RedBaron | Tangent: Each of those needs two capacitors to filter out the voltage spikes. You can find the simple schematic for it on texas instruments site. just search on the part number. |
| 12:56:53 | Tangent | RedBaron : Those parts look pretty much ideal :) |
| 12:58:11 | RedBaron | Tangent: Yeah. they work pretty well. my last job used them to regulate some batteries for a microcontroller and even a motor driver. they used the higher amperage ones for that though. |
| 13:16:29 | RedBaron | boris: Howdy howdy |
| 13:17:11 | boris | hi hi |
| 13:19:43 | RedBaron | How goes? |
| 13:20:09 | boris | not too bad |
| 13:20:12 | boris | tired |
| 13:43:34 | Tangent | brb... keyboard screwed.. looks like shift has been remapped to delete... |
| 13:43:36 | Tangent | most annoying |
| 13:49:48 | prpplague | morning all |
| 13:51:09 | mallum | hi prpplague |
| 13:51:12 | RedBaron | prpplague> Afternoon :) |
| 13:51:37 | SpaceCoaster | how is texas today? |
| 13:52:06 | prpplague | little chilly this morning, around 40 |
| 13:52:35 | scanline | is back (gone 04:50:23) |
| 13:54:10 | scanline | is away: class |
| 15:36:58 | Tangent | whips the screws out of his Tux |
| 15:37:41 | mallum | ooh err misus |
| 15:38:00 | Tangent | mallum : Hmm.. good idea... |
| 15:38:09 | Tangent | whips it out and screws his tuxscreen ;() |
| 15:38:19 | mallum | LOL |
| 15:39:24 | Niddix | puts 3 rubber bands around his tux cause he's already lost the screws. |
| 15:42:40 | Tangent | gets ready to make a PCB... http://ipaq.secret.org.uk/TuxScreen/shanip232v2.pdf |
| 15:43:13 | Tangent | Hrm.. I suppose I should check that it's correct really |
| 15:58:24 | collord | is voip possible without big hardware mods? |
| 15:58:45 | Tangent | collord : Fairly small hardware mod.. but it is required |
| 15:59:13 | CosmicPenguin | Tangent: Is it? The modem should be almost exclusively software based |
| 15:59:47 | Tangent | CosmicPenguin : As I understood it.. the audio mod was required to make CPU generated sound work.. |
| 15:59:54 | Niddix | Uggh.. Why won't Inferno install under RedHat 7.1 |
| 16:00:03 | CosmicPenguin | Tangent: Thats right.... forgot about the return path... :) |
| 16:00:07 | Tangent | Niddix : Did you make it an account |
| 16:00:22 | CosmicPenguin | Niddix: It *DOES* install under 7.1... I've got it right here! |
| 16:00:38 | Niddix | Tangent: Yep.. I get SYS: process syscall faults: Segmentation violation |
| 16:00:58 | Niddix | Tanget: When running /home/inferno/install/Linux-386.sh /usr/inferno |
| 16:01:03 | collord | Niddix: did you substitute the new kernel? |
| 16:01:18 | Niddix | I've got a stock 7.1 system. (Just installed it.) |
| 16:01:28 | CosmicPenguin | Niddix: Thats a configuration problem.... its looking for configuration files..... |
| 16:01:32 | Tangent | Niddix : I did my inferno stuff on W2k, so I'm afraid I don't really know.. |
| 16:01:32 | Niddix | 2.4.2-2 kernel |
| 16:01:48 | Niddix | Ugggh.. I guess I can try that. |
| 16:01:50 | CosmicPenguin | Niddix: Just run the linuxemu file directly |
| 16:02:05 | Niddix | CosmicPenguin: I don't need the rest of that junk? |
| 16:02:16 | collord | Niddix: I mean s/kernel/Inferno image thing/ |
| 16:02:18 | CosmicPenguin | ? |
| 16:03:07 | Niddix | CosmicPenguin: The problem is, I get a segfault when trying to install Inferno. |
| 16:03:43 | CosmicPenguin | Niddix: What script? |
| 16:03:56 | Niddix | Linux-386.sh |
| 16:04:08 | CosmicPenguin | I just typed: Linux/386/bin/emu -r/user/projects/inferno and it worked |
| 16:04:35 | Niddix | Hrmmm... |
| 16:04:46 | Niddix | You never ran the install script? |
| 16:10:00 | scanline | is back (gone 02:15:50) |
| 16:44:25 | GoRK | Tanget: www.blurbco.com/~gork/tuxscreen/shanip2-gork6.gif for my current status |
| 16:46:36 | scanline | GoRK: It looks like the phones jack might make it hard to solder to pin 8 |
| 16:47:10 | MicroChip32 | hates c *muttering* |
| 16:48:25 | MicroChip32 | beats MacAtack over the head with a C manual screaming "I Hate C! I Hate C!" |
| 16:49:07 | scanline | C combines the speed and efficiency of assembly languge |
| 16:49:13 | GoRK | scanline: eh? |
| 16:49:17 | scanline | with the portability and readability of assembly language |
| 16:49:24 | scanline | likes assembly language |
| 16:49:34 | MicroChip32 | scanline: assembly i can handle |
| 16:49:34 | GoRK | i only know z80 asm |
| 16:49:37 | MacAtack | thinks assmelby is the devil |
| 16:49:45 | MacAtack | assembly tooo |
| 16:49:58 | scanline | MicroChip32: C is just assembly language that ignores whitespace |
| 16:50:05 | GoRK | scanline: did you mean hard *not* to accidentally solder to pin 8? |
| 16:50:15 | MicroChip32 | scanline: ummm i think c is a bit more than that *lol* |
| 16:50:20 | MicroChip32 | daggone picky |
| 16:50:28 | scanline | GoRK: I mean the back of the phones jack might block the hole for pin 8 |
| 16:50:45 | scanline | MicroChip32: Yes, i exaggerate... |
| 16:51:03 | GoRK | scanline: no it only comes to the white outline... i am switching models of jack anyway, so i'll account for it |
| 16:51:14 | scanline | ok |
| 16:51:21 | scanline | looks nice :) |
| 16:51:32 | scanline | put me down for one |
| 16:51:55 | GoRK | scanline: im not sure the mic/line in's work properly yet.. i mean they work but not properly :) |
| 16:52:07 | scanline | ah. levels are wrong? |
| 16:52:26 | MacAtack | GoRK (et al): what is the ShanIP thing do/gonna do? VoIP ?????? |
| 16:52:28 | GoRK | no it's got some buzzing.. |
| 16:52:39 | scanline | oh yeah |
| 16:52:52 | scanline | MacAtack: It will be kinda like a sound card for the Tux |
| 16:53:15 | GoRK | macattack: the tuxscreen includes the ucb1200 audio interface but it's not hooked to anything. This adds all the elements to it to make it a fully functional sound device and it also couples it to the DSP audio so we can record/play to the speakerphone and handset stuff |
| 16:53:23 | MicroChip32 | scanline: so its not modifying existing functionality, but rather adding functionality |
| 16:53:26 | scanline | MacAtack: The tuxscreen has sound input/output on the ucb1200, but it's not connected. shanip2 connects it to the handset and speakerphone, and GoRK's adding souncard-style plugs |
| 16:53:34 | scanline | MicroChip32: yes |
| 16:53:59 | scanline | shanip2 is something every tuxscreen owner should have |
| 16:54:01 | scanline | :) |
| 16:54:02 | GoRK | MicroChip32: more like completing functionality that was there but unused |
| 16:54:14 | MicroChip32 | GoRK: yea, like the 2nd serial port, et al |
| 16:54:32 | GoRK | which second serial port are you speaking of? |
| 16:54:32 | AlHazWork | the wheel for volume controll might make it tricky to cut out the case for people who lack dremel tools |
| 16:54:47 | MicroChip32 | GoRK / scanline: does/will it interfere at all with the handset/spkr function ? |
| 16:54:51 | GoRK | if you mean the ssp, in theory we can hook a DAC up to it and get another soundcard :) |
| 16:54:53 | scanline | GoRK: GPSFan discovered a simple mod to add a 2nd serial port |
| 16:54:54 | AlHazWork | maybe you could adjust the circuit so that it could also accept a pot that's just got a post sticking out to twist? |
| 16:55:04 | AlHazWork | then it's just four holes to drill |
| 16:55:13 | MicroChip32 | GoRK: the unused one on the 1100 |
| 16:55:48 | scanline | GoRK: I don't think it's the SSP. it's the second rs232 port. He uses the RTS/CTS line drivers on the existing max232 chip |
| 16:56:03 | scanline | just cut some traces, solder some wires, add a plug |
| 16:56:25 | MicroChip32 | scanline: whoever was talking about it found that there's a fully unused serial port on the chip, no need to steal the rts/cts from current port |
| 16:56:28 | MacAtack | Kewl stuff... now would this be somthing that would output say PCM 16bit audio |
| 16:56:37 | GoRK | AlHaz: the phones vol is a thumbwheel pot... you could solder up a different kind on some wires and put a volume knob anywhere you wanted |
| 16:56:37 | MacAtack | thinkin mobile mp3 player for the car |
| 16:56:50 | GoRK | yeah it can do 44khz 16 bit mono |
| 16:57:00 | MicroChip32 | scanline: at least that was my understanding of it. needing only to add ones own rs232 |
| 16:57:00 | MacAtack | that would work KEWL |
| 16:57:06 | scanline | MicroChip32: The RTS and CTS lines are just GPIOs. The reason to steal them is not the CPU, but a limited number of line drivers on the board |
| 16:57:34 | GoRK | i think the ssp can be used for usb too |
| 16:57:35 | MicroChip32 | scanline: it aint hard to add your own 232 man |
| 16:57:43 | scanline | if you add another max232 chip you can add a new port without messing with Rts/cts |
| 16:58:02 | scanline | MicroChip32: right. GPSFan just likes coming up with really cheap/simple mods :) |
| 16:58:13 | MicroChip32 | scanline: yea thats what i had in mind. personally thinking about adding smart-card functionality to it |
| 16:58:24 | scanline | smart cards are rs232? |
| 16:59:32 | MicroChip32 | scanline: yes and no. theyre serial, but need external clocking |
| 16:59:59 | scanline | so they're async serial. You could bit-bang an interface to that with GPIOs |
| 17:00:07 | scanline | err... sync serial |
| 17:00:09 | MicroChip32 | scanline: probably, yes |
| 17:00:22 | GoRK | or add a support chip |
| 17:00:36 | scanline | a PIC would be easy |
| 17:01:02 | Lenolium | So, has someone started a production run of the Sanip2 board yet? |
| 17:01:11 | MicroChip32 | scanline dont even need that. the interface i have around here somewhere just uses a 7400 chip and a crystal to interface it to a standard 9600 rs232 |
| 17:01:11 | GoRK | i have a smartcard *ahem* programmer here that is fairly simple |
| 17:01:15 | GoRK | Lenolium: it's not done yet |
| 17:01:32 | Tangent | Lenolium : I'm about to knock out four of them as soon as I can work out how to combine 4 copies of the same file on one page |
| 17:01:47 | Lenolium | GoRK: Ahh.. -k- |
| 17:01:51 | scanline | MicroChip32: that's neat |
| 17:02:09 | Lenolium | Tangent: Hey, would you make 8 for me? :) |
| 17:02:17 | MicroChip32 | scanline: this is basic, might not work with all types of smart cards tho |
| 17:02:21 | scanline | Tangent: I want one too :) |
| 17:02:22 | GoRK | Lenolium: well the one on ipaq.secret.org is functional for just routing audio to the handsets, etc |
| 17:02:37 | Tangent | Lenolium : I can only make four at the moment.. I'm on my last piece of transfer paper... |
| 17:02:43 | Lenolium | Tangent: Hehe. |
| 17:02:47 | Tangent | Lenolium : I'd have to order some more supplies to make more than 4 |
| 17:03:00 | Lenolium | Tangent: Oh well, I bet you aren't in Salt Lake either. |
| 17:03:12 | Tangent | Lenolium : Nope.. I'm in London |
| 17:03:14 | scanline | that's ok... I have my electrical tape solution until we get a batch of GoRK's latest design |
| 17:03:48 | GoRK | i need to find someone local who sells press n peel so i dont have to order it |
| 17:03:59 | GoRK | and i need to get an order into mouser for some junk |
| 17:04:02 | scanline | radium shack |
| 17:04:05 | Lenolium | Tangent: Geez, you're just trying to make my life difficult, aren't you? ;) |
| 17:04:11 | GoRK | ratshack doesnt :( |
| 17:04:28 | scanline | no press&peel at radium shack??? what has the world come to! |
| 17:04:45 | Tangent | Lenolium : Not quite.. I'm trying to get you to make my life easy ;) |
| 17:06:19 | AlHazWork | *sigh* somebody get lilo a job, we need to keep him busy so we can all irc in peace |
| 17:06:38 | GoRK | haha |
| 17:06:40 | Lenolium | I think he has one... that's the scary part. |
| 17:06:55 | scanline | I think he just likes rebooting servers randomly |
| 17:07:08 | Lenolium | They run this network like people run a Windows NT machine, split and reattach until it works properly. |
| 17:07:35 | AlHazWork | Lenolium: he got one? last I heard he was moving into his parents basement . . . |
| 17:08:30 | Lenolium | AlHazWork: Looks like I could be wrong. |
| 17:27:44 | Tangent | finally manages to get things printing properly |
| 17:39:47 | scanline | is away: food |
| 17:41:22 | Tangent | has managed to fit 16xshanip+rs232 boards onto one sheet of A4 press & peel |
| 17:44:55 | Lenolium | *plong* |
| 17:46:55 | RedBaron | Tangent: this shanip2 ... is their a pict of it around? |
| 17:47:20 | Tangent | RedBaron : There's schematics, and now two different PCB layouts... |
| 17:47:37 | RedBaron | Tangent: So what is it? :) |
| 17:47:42 | Tangent | RedBaron : One layout has Audio Connectors... my layout has no audio connectors, but does have an extra rs232 port |
| 17:47:44 | RedBaron | Tangent: Just sound or more? |
| 17:47:48 | GoRK | i could take a picture of my breadboard :) |
| 17:47:59 | RedBaron | GoRK: chuckle |
| 17:48:12 | Tangent | RedBaron : The shanip2 is just sound... I've been caling mine shanip232 in my filenames |
| 17:48:42 | RedBaron | Tangent: Ah...okay. and this uses the ucb1200 sound, and ties the input/output to the handset? |
| 17:49:06 | Tangent | RedBaron : Yep that's right |
| 17:49:32 | Tangent | RedBaron : I added stuff for the second rs232 port on the CPU too... |
| 17:50:15 | RedBaron | Tangent: okay. just trying to catch up. :) Whats the capabilities of the ucb1200 sound? I saw something about cpu generated sound. can the ucb1200 do its own sound generation or does the CPU have to baby it a lot? |
| 17:51:24 | Tangent | RedBaron : You know.. I'm not entirely certain |
| 17:51:59 | RedBaron | Tangent: Okie. |
| 17:52:29 | RedBaron | does alittle research to find out himself. rtfm...eh? :) |
| 17:56:36 | RedBaron | Hmm...dinner time |
| 18:01:59 | SteevD | is AWAY at 19:04:42 : out but will read later |
| 18:02:47 | MicroChip32 | ut oh, eveyrone hide, BZFlag is here |
| 18:02:56 | MicroChip32 | s/eveyrone/everyone/ |
| 18:04:02 | scanline | is back (gone 00:24:15) |
| 18:07:46 | rfs | kicks his stupid IRC client. |
| 18:18:31 | GoRK | Tangent: have you tested the serial port mod? |
| 18:26:47 | Tangent | GoRK : It's etching right now |
| 18:27:31 | Tangent | GoRK : It'll be a few hours before I've drilled all the holes etc... |
| 18:30:22 | scanline | Tangent: You made a PCB for the max232? |
| 18:30:32 | Tangent | http://ipaq.secret.org.uk/TuxScreen/shanip232v2.pdf |
| 18:31:03 | Tangent | scanline : Technically, I'm still making it ;) |
| 18:31:25 | Tangent | scanline : I'm gonna have four of these... |
| 18:31:40 | Tangent | scanline : And easily be able to make another 12 |
| 18:31:55 | Tangent | I only need two |
| 18:33:28 | scanline | watches gv chug away at rendering the PDF... |
| 18:33:58 | scanline | hmm... shanip2 plus space for a serial port connector and max232 |
| 18:34:03 | scanline | no line in/out/etc? |
| 18:35:09 | Tangent | scanline : I didn't care for line in/out etc... |
| 18:35:19 | Tangent | scanline : I can always add them later... along with USB |
| 18:35:41 | scanline | So JP2 and JP3 would be for the audio connectors? |
| 18:37:53 | GPSFan | Tangent: your rev 2 board looks real nice. you think you will have your protype etched & drilled today? |
| 18:45:50 | Tangent | GPSFan : Should do... another 10 mins and the etch will be done |
| 18:47:43 | BZFlag | what's the serial port mod for? |
| 18:48:24 | Tangent | BZFlag : Going to tie it into the unused serial port on the sa1100 |
| 18:48:53 | GPSFan | great, I took off the connector bodies of J600, & J601, and you have to cut the traces on both sides of pin28 to clear the ground. I have a pic. if you are interedted. |
| 18:49:17 | Tangent | GPSFan : Yeah.. I'm definately interested |
| 18:49:26 | GPSFan | Tangent: you don;t have to remove the connector body to do that though. |
| 18:50:58 | BZFlag | Tangent: ahh, so not modifying the serial port, but adding another. cool! |
| 18:51:31 | BZFlag | Tangent: early rev sa1100 like in the tux had very broken usb. don't go there. |
| 18:52:01 | Tangent | BZFlag : OK.. that makes my life easier :) |
| 18:54:37 | CosmicPenguin | BZFlag: Thats too bad, because USB would be very cool.... |
| 18:54:47 | GPSFan | BZFlag: Serial 1 on the SA1100, is like 2 & 3, and is unused, the idea is to either use an external MAX232 like Tangent, or use the GPIO RTS/CTS lines that go out the existing serial port. The USB port (slave only at best) comes out J602. |
| 18:55:22 | CosmicPenguin | Though, a slave USB wouldn't be nearly as nice.... :( |
| 18:55:53 | GPSFan | Tangent: pic at: http://tuxscreen.net/download/schematics/serial2.jpg |
| 18:56:30 | Tangent | GPSFan : Excellent... Thank you.. that'll do nicely :) |
| 18:56:45 | prpplague | GPSFan: love the coloring job... |
| 18:57:16 | GPSFan | prpplague: I never took art in school... ;>) |
| 18:57:41 | Tangent | GPSFan : So the Rxd1 line is shorted to ground in three places... They really wanted to be certain didn't they? |
| 18:57:46 | prpplague | GPSFan: what kind of camera did you use, i can't get that close to a pcb with my camera |
| 18:57:48 | MicroChip32 | GPSFan: whats this pic, is this the mods to use the existing rts/cts for a 2nd serial (as opposed to using the unused sa1100 port) |
| 18:59:13 | Tangent | GPSFan : Are there RTS and CTS lines for the second port too? |
| 18:59:27 | Tangent | GPSFan : I'm guessing not |
| 18:59:35 | GPSFan | MicroChip32: this pic shows how to use the RS232 Drivers that were driving RTS/CTS of the existing serial port. To drive the TXD RXD lines from the existing, but unused serial port #1 of the SA1100. |
| 19:00:05 | MicroChip32 | oic |
| 19:00:29 | GPSFan | Tangent: there are only RTS/CTS lines for the existing serial port because Phillips decided to bit-bang them using GPIO's. |
| 19:01:18 | GPSFan | prpplague: the trick to close up photogtaphy is 2 fold, 1) enough loght, 2) close-up lens kit. |
| 19:01:22 | CosmicPenguin | New Java OS runs on "bare metal", supports iPAQ: http://linuxdevices.com/news/NS8885915946.html |
| 19:01:52 | prpplague | GPSFan: hmm i wonder if there is a kit for my sony |
| 19:02:33 | GPSFan | prpplague: does it have a threaded lens ring in front? |
| 19:02:36 | BZFlag | what are the circles on 27? cuts? |
| 19:02:43 | MicroChip32 | grrrr brb, reboot (windows sucks) |
| 19:03:26 | prpplague | GPSFan: negative, its on the low end of things, maybe upgrade next year, i'm still saving my beer money for a LART |
| 19:03:58 | GPSFan | MicroChip32: pin 27 and 28 are tied to ground on the comms board. pin 27 is ground on the CPU board, you must make the 3 red circled cuts to clear the ground from pin 28, which is RXD1 on the CPU board. |
| 19:04:39 | prpplague | man i wish this was arm based - http://www.cyclades.com/products/stdalone/pr2000.htm#backview |
| 19:05:41 | GPSFan | prpplague, if not, then get a magnifing glass and put it in front of the lens. it will allow you to get closer to the subject. Maybe close enough for what you want to do. This is a hard trick to manage with only 2 hands. ;>) |
| 19:06:02 | BZFlag | CosmicPenguin: you know of course, that that's where shaggy works right? shaggy did a lot of the code on the shannon. |
| 19:06:19 | prpplague | GPSFan: i'll try that next time, thanks |
| 19:08:56 | GPSFan | prpplague: save your money for a CreditLart ;>)) http://wearables.blu.org/wear-hard-01/20014339.html |
| 19:09:12 | Tangent | Woohoo.. my board is all etched... |
| 19:09:42 | GPSFan | Tangent: can you take a pic of it after you clean off all the etchant? |
| 19:09:53 | CosmicPenguin | BZFlag: I didn't know that shaggy worked there... He must be an awesome SA11XX programmer..... |
| 19:10:18 | CosmicPenguin | BZFlag: Can we convince him to come to our side? |
| 19:10:28 | Tangent | GPSFan : Pictures uploading now |
| 19:11:04 | CosmicPenguin | prpplague: Why do you wish that was ARM based? |
| 19:11:34 | BZFlag | CosmicPenguin: I keep in touch with him from time to time. He's pretty much heads down on the savaje stuff. he does plan to try our stuff out and comment on it when he gets the chance. |
| 19:12:49 | Tangent | wants a new camera |
| 19:13:26 | MicroChip32 | Tangent: hey i use my palm pilot for a digital camera. just cant do close ups with it |
| 19:13:33 | CosmicPenguin | BZFlag: I understand that he may be "tainted".... :) |
| 19:13:50 | prpplague | CosmicPenguin: we do a lot of frame-relay, p-t-p dds , and dry line circuits, and we need to include a lot of line diagnostics, but we can't get any of the router mamufacters to add diags to our specs |
| 19:15:37 | BZFlag | CosmicPenguin: yes, but nobody seems to care anymore. |
| 19:15:49 | CosmicPenguin | prpplague: I understand.... but surely, you wouldn't want an ARM as the core processor in your router? |
| 19:16:25 | CosmicPenguin | BZFlag: Until somebody decided to copy the design, I would guess.... :) |
| 19:16:53 | BZFlag | eh, it would make more sense to use the lart stuff now. |
| 19:17:30 | Tangent | GPSFan: http://ipaq.secret.org.uk/TuxScreen/Etching.jpg http://ipaq.secret.org.uk/TuxScreen/Etched.jpg |
| 19:17:37 | BZFlag | the sa1100 is not even available now. |
| 19:17:57 | Niddix | Wow.. I'm actually transfering something to the tux.. yahoo. |
| 19:18:04 | prpplague | CosmicPenguin: we i say, i'm just whin'ing because i'm beginning to get comfortable with ARM and don't want to learn another cpu enviroment |
| 19:18:09 | prpplague | s/we/when |
| 19:18:13 | Tangent | GPSFan : Only two of the four boards are problem free.. the others can easily be touched up tho |
| 19:18:40 | CosmicPenguin | prpplague: I understand that..... As long as you stick with RISC, you shouldn't be too bad... :) |
| 19:19:57 | Niddix | GPSFan: Did you every get those Inferno memory registers you wanted? |
| 19:20:24 | GPSFan | Tangent: nice, did you use the laser printer toner transfer system? btw this is a pic I took with my cheap Agfa e-photo 780. no closeup lens, but I used my Luxo desk lamp magnifier as both an aux lens and illuminator. |
| 19:20:34 | GPSFan | Tangent: http://wearables.blu.org/wear-hard-01/20014339.html |
| 19:21:00 | Tangent | GPSFan : Yeah.. that was laser printer stuff |
| 19:21:15 | Tangent | GPSFan : It's really pretty good :) |
| 19:22:01 | GPSFan | Tangent: oops this is the URL http://tuxscreen.net/download/schematics/j601.jpg |
| 19:23:44 | GPSFan | Niddix: no, I never did. did you ever ger Inferno upgraded or did you go straight to Linux? |
| 19:23:57 | Tangent | GPSFan : Yeah... that looks more like what my camera achieves |
| 19:24:46 | GPSFan | Tangent: that last one is 640 x 480 the others I used my Agfa e-photo1280 at 1280 x 960. |
| 19:25:20 | Tangent | GPSFan : I have a Fuji MX700... It's OK, but I'm starting to get really fed up with it being fixed focus |
| 19:25:20 | MicroChip32 | Tangent: is that a photo-etch system i presume ? |
| 19:25:42 | Tangent | MicroChip32 : No.. just print onto special paper with a laser printer.. iron it on... then etch |
| 19:25:57 | MicroChip32 | Tangent: cool |
| 19:26:15 | GPAFan_away | bbiaw |
| 19:26:29 | MicroChip32 | GPA ? |
| 19:26:35 | Tangent | MicroChip32 : The paper is about $3 per sheet |
| 19:27:36 | MicroChip32 | Tangent: ouch. but would be worth it if you do much prototyping. then ya gotta have the laser printer. |
| 19:28:33 | Tangent | MicroChip32 : Fortunately I do have the laser... I discovered that if I turn the print density up, I can iron on the laser printer toner direct to the top of the board for a cheap silkscreen too :) |
| 19:29:53 | MicroChip32 | lol |
| 19:35:51 | SpaceCoaster | Tangent: is it this stuff http://www.techniks.com/press-n-peel.html ? |
| 19:37:11 | Tangent | SpaceCoaster : Yep.. that's exactly the stuff... same paperwork with it :) |
| 19:37:13 | Tangent | goes off to drill and slice |
| 19:45:32 | SpaceCoaster | Found this pcb software http://lwn.net/2000/features/pcb/ |
| 19:47:46 | Lenolium | *pling* |
| 19:48:31 | RedBaron | So does anyone know about how much of a sound card the ucb1200 is? and how much support the CPU will need to give? |
| 19:48:32 | prpplague | Tangent: i've always wanted to try and make my own pcb, where do you guys get the supplies? |
| 19:49:34 | prpplague | SpaceCoaster: nice article SpaceCoaster |
| 19:50:26 | kernelwork | Call me lazy, but I have always wanted a free software PCB design utility that does autorouting. |
| 19:50:50 | prpplague | SpaceCoaster: when i worked in the oil industry a bunch of the EE guys made pcb with all the traces looking like naked women |
| 19:51:51 | SpaceCoaster | tries to think of mucky jokes involving ground planes etc. |
| 19:52:19 | RedBaron | prpplague: Back in high school, the school had a very simple 3 stage tank for the film and for etching. I dont know where they got it, but I would guess its realy a matter of getting the chemicals, the blank board, and a UV lamp. |
| 19:56:22 | MacAtack | are the jtag's like a universial thing... i was just told i need to get a jtag for another project i'm working on and the schematic they sent me has less parts |
| 19:58:55 | MacAtack | and now that i look at it its almost compleetly different other than the TSSOP chip.. this one has resistors and a voltage regulator on it |
| 20:01:19 | Tangent | prpplague : I get my supplies from my local Maplin store... |
| 20:02:01 | Niddix | prpplague: RadioShack usually stocks everything you'd need. |
| 20:02:33 | prpplague | Niddix: i boycott radioshit |
| 20:02:45 | MacAtack | prpplague: me too |
| 20:03:14 | prpplague | they turned their backs on the ppl who made them a big business |
| 20:03:30 | MicroChip32 | ratshit costs too much, unfortunately theyre the only place around here to find electronics |
| 20:06:16 | Niddix | prpplague: I usually avoid them as well, unless I'm in a crunch. You have Siemens or Greybar where you live? |
| 20:06:53 | prpplague | Niddix: negative, i live out in the styx |
| 20:08:42 | Niddix | prpplague: http://www.web-tronics.com/printed-circuit-board-supplies.html |
| 20:11:01 | prpplague | Niddix: thanks for the link, guess i need to order some supplies |
| 20:15:55 | Tangent | Hrm.. my only problem now is that I'll need a Max3232 to run from 3.3V... and I don't have any of them... and they don't sell them locally... and I don't want to pay the shipping on a $3 part |
| 20:16:48 | Niddix | Tangent: Get your parts supplier to order one? |
| 20:17:08 | Tangent | Niddix : Nah.. they suck |
| 20:17:18 | Niddix | Tangent: ;) |
| 20:17:33 | Niddix | Tangent: Well then, you have a problem. |
| 20:18:08 | BZFlag | MacAtack: jtag is a general standard. should interoporate, but might not have software support for all the options etc. |
| 20:19:16 | BZFlag | different jtag devices operate at very different speeds due to clocks and buffering. |
| 20:19:35 | BZFlag | the par port dongle is about the slowest I've seen, but also the cheapest. ;-) |
| 20:20:29 | Niddix | I'm syched.. I was finally able to load the new inferno image. |
| 20:22:25 | Tangent | Niddix : Heh.. just discovered that my local supplier does have the 3232 :) |
| 20:22:27 | MacAtack | BZFlag: ok thanks |
| 21:06:37 | GPSFan | Tangent: if you have clear skys tonight go out and see if you can see the aurora. http://www.spaceweather.com/ |
| 21:08:15 | Tangent | GPSFan : I'm in the UK.. no chance for me |
| 21:08:25 | Russ | I'm in arizona... |
| 21:08:38 | GPSFan | Tangent: london? |
| 21:09:22 | Tangent | GPSFan : That's right |
| 21:09:46 | Tangent | GPSFan : Well.. I've built the shanip part of my board now.. all I need to do is to hook it up.. |
| 21:10:08 | GPSFan | Tangent: this was taken in Scotland just a while ago. http://www.spaceweather.com/aurora/images/06nov01/VieiraLinhares1.jpg |
| 21:11:29 | Tangent | GPSFan : Cooool :) |
| 21:11:34 | GPSFan | Tangent: good luck witg shanip232 ;>) |
| 21:11:45 | GPSFan | s/witg/with |
| 21:12:18 | Tangent | GPSFan : Sadly it's cloudy here.. I just went for a look |
| 21:12:41 | Tangent | GPSFan : Will I find all the connection details on erire.com? |
| 21:13:03 | scanline | Tangent: Are you using the latest shanip2.pdf schematic? |
| 21:13:25 | Tangent | scanline : Something close... |
| 21:13:38 | GPSFan | Tangent; bummer :>( scanline's done it. he is the expert today. |
| 21:14:00 | scanline | I'm no electronics guru, that's GPSFan's job |
| 21:14:26 | Tangent | Hang on.. I'll stick a PDF online |
| 21:14:39 | GPSFan | scanline: maybe not, but you have direct experience. |
| 21:15:04 | scanline | GPSFan: Yeah... I think so far it's still just GoRK and I who've actually used this thing? |
| 21:15:49 | scanline | Tangent: Just make sure your circuit has R6 = 2.2k, and that it has R21. Those were our most recent changes I think |
| 21:16:23 | scanline | There are a few wiring changes... the output goes to a via connected to an op-amp now, not a mongoose pin |
| 21:16:25 | Tangent | scanline : It's about 1 hour too late to tell me that :) |
| 21:16:36 | Tangent | http://ipaq.secret.org.uk/TuxScreen/shanip232-schematic.pdf |
| 21:16:39 | scanline | and you'll need a jumper for the speaker power supply, not pictured on the schematic |
| 21:16:55 | scanline | Tangent: Worst case you'll have to dangle 1 resistor somewhere in the air :) |
| 21:17:09 | GPSFan | Tangent: refer to: http://tuxscreen.net/download/schematics/ucb.jpg and: http://tuxscreen.net/download/schematics/emain66by.jpg |
| 21:17:30 | scanline | it also might be helpful to have a ucb1200 data sheet |
| 21:17:31 | prpplague | scanline: nothing worse than a dangling resistor |
| 21:17:38 | scanline | hehe |
| 21:17:58 | scanline | Tangent: This looks kinda like Eagle CAD... |
| 21:18:25 | Tangent | scanline : Hmm.. funny that :) |
| 21:18:30 | GPSFan | scanline: this is the fun part helping someone 1/2 way around the world get it running! ;>) |
| 21:18:42 | scanline | Tangent: looks fine except that R7 should be 2.2k, not 1.2k |
| 21:18:51 | scanline | 1.2k will work, but 2.2k sounds much better |
| 21:19:27 | GPSFan | Tangent: R4 isn't needed, but won't hurt. |
| 21:19:44 | scanline | Tangent: Pins 1 and 2 on JP1, along with pin 2 of JP2 and all of JP3 are probably unnecessary |
| 21:20:04 | scanline | GPSFan: ah, yeah I didn't notice R4... |
| 21:20:46 | Tangent | scanline : Yeah.. I just copied the jumper block config from GPSFan's schematic |
| 21:20:54 | scanline | GPSFan: I did notice that the shanip2.pdf on tuxscreen.net has the new resistor values and lacks that 68ohm resistor. Thanks for updating it |
| 21:21:22 | GPSFan | ;>) my pleasure. |
| 21:21:27 | scanline | Tangent: JP3 would only serve to provide 5v to a PCMCIA mod, but with GPSFan's new much simpler pcmcia mod, it's not necessary |
| 21:22:23 | GPSFan | scanline: my mod hasen't been totally proved yet, Tangent did the Lucent version. |
| 21:22:41 | BZFlag | GPSFan: andersee got it working, no? |
| 21:22:41 | scanline | GPSFan: But andersee did your mod and was sucessful? |
| 21:23:21 | Tangent | Here's my little board... http://ipaq.secret.org.uk/TuxScreen/InPlace.jpg |
| 21:24:02 | scanline | Tangent: Cool. How'd you mount it? |
| 21:24:30 | prpplague | Tangent: i haven't been following, whats this board do? |
| 21:24:36 | GPSFan | BZFlag: yes he did, but with only 1 NIC card to test it is still not 100% sure. However my mod just changes where you change the 3.3V to 5V, the reset mod could always be added if we find that only a few cards work without it. |
| 21:24:41 | Tangent | scanline : At the moment.. just by the power of Gravity |
| 21:25:05 | Tangent | scanline : I was figuring that a little milliput under the board would do the job... That and the bolts on the RS232 connector |
| 21:25:08 | MicroChip32 | Tangent: sweet |
| 21:25:10 | scanline | Tangent: Okeydokey. Once you get the DB9 connector installed, you could use that to mount |
| 21:25:26 | scanline | milliput? Is that anything like hot glue? |
| 21:25:30 | Tangent | Yeah.. That part's gonna have to wait until tommorow.. |
| 21:25:43 | GPSFan | or BlueTak? |
| 21:25:49 | Tangent | scanline : Potting compound type stuff.. Mix the two halves.. it heats up.. then turns solid later |
| 21:25:52 | MicroChip32 | or silly putty? <G> |
| 21:26:06 | prpplague | old gum? |
| 21:26:09 | scanline | Tangent: Sounds like something a dentist would use for their torturing... |
| 21:26:21 | MicroChip32 | old gum? *spits koolaid all over his keyboard* |
| 21:26:26 | MicroChip32 | is rotfl |
| 21:28:40 | prpplague | MicroChip32: don't knock time you've been in need, did that once when i was in st.croix after a hurricane, bought a big bag of that nasty gum that comes wrapped in stupid jokes |
| 21:29:43 | prpplague | used it to putty up a conduit leaking water into the telco breakout box |
| 21:31:39 | MicroChip32 | prpplague: lolol, yep ive used old gum for stuff to, the right kind works almost as many wonders as duct tape |
| 21:36:06 | Russ | hmm...if there is an ethernet card, mount gets stuck in a running state |
| 21:36:35 | MicroChip32 | ok who here knows the sscanf function inside and out ? |
| 21:38:20 | scanline | MicroChip32: What is it you want to know? |
| 21:38:31 | MicroChip32 | scanline: sec |
| 21:39:11 | Russ | mount R current 4692 73 1 9 (NOTLB) |
| 21:39:17 | MicroChip32 | scanline: can i msg you |
| 21:39:21 | MicroChip32 | may i |
| 21:39:23 | MicroChip32 | ;)_ |
| 21:39:27 | scanline | yes |
| 21:55:48 | CosmicPenguin | Is there anything better than having the hardware guy say... "Oh... thats our fault?" |
| 21:56:41 | scanline | Congrats! |
| 21:59:01 | Tangent | GPSFan : What does the Green circle on ucb.jpg represent? |
| 22:01:36 | Hiraghm | Hi |
| 22:01:45 | Hiraghm | waves near BZFlag |
| 22:02:55 | Hiraghm | waves near microchip |
| 22:03:29 | MicroChip32 | waves at Hiraghm and 'accidently' smakes him. solly ;) |
| 22:03:30 | Tangent | Hiraghm : hi |
| 22:03:46 | Hiraghm | waves near Tangent |
| 22:07:07 | MicroChip32 | CosmicPenguin: yea ... having MS say it ;) |
| 22:08:26 | scanline | haha |
| 22:09:16 | Hiraghm | say what? |
| 22:09:43 | Tangent | OK.. Well i've got three wires to connect now... GND, Frame_Gnd and Signal_Gnd |
| 22:09:47 | SpaceCoaster | CosmicPenguin: is that your missed interrupt? |
| 22:10:33 | SpaceCoaster | s/missed/missing/ |
| 22:12:12 | Tangent | I don't suppose that GND is conveniently U500-14 ? |
| 22:14:18 | Tangent | wonders what J602 is for |
| 22:14:36 | MicroChip32 | Tangent: apply 200vdc to it and see what sparks ;) |
| 22:15:12 | Tangent | MicroChip32 : One sec.... Hmm.. must have been connected to everything... Now what do I do with all this smoke? |
| 22:15:27 | MicroChip32 | Tangent: save it for repairs :) |
| 22:17:04 | GPSFan | Tangent: the green circle is the speakerVCC for the UCB1200, needs to go to 3.3V |
| 22:18:14 | Tangent | GPSFan : Are U500-11 and 12 suitable for the ground connection? |
| 22:18:24 | GPSFan | What is U500? |
| 22:18:44 | Tangent | GPSFan : I mean IC500 |
| 22:19:48 | GPSFan | IC500 is under the Mongoose board, an LM324 is this the one you mean? |
| 22:20:22 | Tangent | GPSFan : Yeah.. that's the one |
| 22:20:24 | scanline | Tangent: That IC500 pin is audio output. If you need a ground, the serial port is convenient |
| 22:20:54 | scanline | there's also a ground on the ucb1200 |
| 22:21:08 | Tangent | scanline : I've got three grounds to connect |
| 22:21:19 | scanline | not really... |
| 22:21:32 | scanline | the only one that's separate is microphone ground |
| 22:21:37 | Tangent | scanline : I've got a 4-way ribbon cable for the three connections to IC500 + ground... |
| 22:21:42 | scanline | signal gnd, frame gnd, and ground is the same thing |
| 22:21:45 | Tangent | scanline : I have no Microphone... |
| 22:22:04 | Tangent | scanline : Yeah... but it's good for cutting down signal noise |
| 22:22:08 | scanline | uh... the ucb1200's audio input is labeled as a microphone input |
| 22:22:23 | scanline | i'd recommend connecting to the ucb1200's ground pin |
| 22:22:48 | scanline | there are 2 pins (sorry, don't know the numbers) going to a .1uf cap. The one closest to the ucb1200 is 3.3v, the other is gnd |
| 22:23:00 | Tangent | scanline : I'll do that for Frame & Signal Gnd... I just want something close to IC500 for the last gnd connection |
| 22:23:16 | scanline | oh |
| 22:23:32 | scanline | well, with the quality of the speakers used in the Tux it shouldn't matter :) |
| 22:24:12 | GPSFan | Tangent: the location for the black wire in: http://tuxscreen.net/download/schematics/emain66by.jpg should be sufficiently close |
| 22:25:08 | Tangent | GPSFan : That's on the other PCB.. on the other side of the shield |
| 22:25:27 | Russ | Tangent: if I put an ethernet card in, mount get stuck in a running state, and pinging gives a 41% packet loss |
| 22:25:46 | Tangent | Russ : Hrm... :( |
| 22:26:24 | Tangent | GPSFan : |
| 22:26:28 | Tangent | Doh |
| 22:26:29 | GPSFan | Tangent: that is on the comms PCB, which is where IC500 & IC300 (UCB1200) are |
| 22:26:53 | Tangent | GPSFan : Not my IC500 ... my IC500 is on the bottom PCB |
| 22:28:10 | GPSFan | Tangent: there is an IC500 on the CPU board too, it is not the one. you can't get at IC500 on the comms board without removing the Mongoose module. |
| 22:29:10 | GPSFan | Tangent: but in the pic: http://tuxscreen.net/download/schematics/emain66by.jpg the red circle is over the pad that connects to IC500 pin 13. |
| 22:29:46 | Petey | do i need to do a +5v mod to add ethernet? |
| 22:29:50 | Tangent | GPSFan : Ah... so IC500 is under that metal box then? |
| 22:29:58 | Tangent | Petey: Depends on your ethernet card |
| 22:30:31 | Petey | I don't have one yet.. well, I have a trendware sitting around but I might get another, since the dongle only works sometimes.. |
| 22:30:52 | Petey | I can get a used 3com 10/100 for $20 |
| 22:30:59 | Petey | if that'll work |
| 22:31:27 | GPSFan | Tangent: yes, that's why the pic shows to connect to a trace on the back of the board. I took the original Lucent pic and added the red circle, after some photoshop enhancement. |
| 22:32:07 | Tangent | GPSFan : That pic isn't the most self explanitory tho' |
| 22:32:17 | Tangent | GPSFan : Needs more red lines :) |
| 22:33:08 | GPSFan | Tangent: that's true, i talked scanline through it and helped GoRK to connect hsi up because the Lucent pics sucked. |
| 22:33:23 | GPSFan | s/hsi/his |
| 22:33:41 | Tangent | GPSFan : I have to admit.. .I'm struggling here |
| 22:35:15 | GPSFan | Tangent: ok, let me print out your schematic. |
| 22:35:20 | scanline | If you want another bad picture, I have one at http://tuxscreen.net/download/shanip2-pictures/frontside.jpeg |
| 22:35:32 | Tangent | GPSFan : The pins on the headers are the same as with yours... |
| 22:35:47 | Tangent | GPSFan : So far I've hooked up USB1200-8&9, 20&21 |
| 22:35:53 | Tangent | s/USB1200/USB1200 |
| 22:36:24 | GPSFan | tan: ok did you hook up UCB1200-10 to 3.3V |
| 22:36:28 | scanline | Tangent: So you also need pin 10, and the 3.3v/Gnd that's adjacent to 20 and 21 |
| 22:36:56 | scanline | Tangent: that orange wire in my little contraption is the jumper from pin10 to 3.3v |
| 22:37:19 | scanline | there's a .1uf cap with a pad that's very close to pin 20's pad |
| 22:37:22 | scanline | that's 3.3v |
| 22:37:24 | Tangent | scanline : Where can I find a closeby 3.3V? |
| 22:37:33 | scanline | :) |
| 22:37:40 | GPSFan | Tangent: that's also the 2 wire that went to the 8-pin shanip header pin 1 & 2 |
| 22:37:47 | Tangent | scanline : You're talking about C314? |
| 22:38:29 | scanline | probably |
| 22:38:47 | Tangent | http://tuxscreen.net/download/schematics/ucb.jpg |
| 22:38:49 | scanline | i know my picture is pretty bad quality too... |
| 22:39:04 | scanline | we need to get GPSfan to build one of these just to he can photograph it :) |
| 22:39:07 | Tangent | scanline : It's just that there's two solder pads on there... |
| 22:39:22 | scanline | looks at the ucb1200 data sheet... |
| 22:39:24 | Tangent | scanline : One close to the UCB1200, and one by the writing that says R306 |
| 22:40:02 | scanline | ok. the power pins you should use are 17 and 18 |
| 22:40:06 | GPSFan | Tangent: tha pad that connects to UCB1200-17 just to the right of the "4" in C314 |
| 22:40:07 | scanline | 17 is +3.3v |
| 22:40:11 | scanline | 18 is ground |
| 22:40:23 | scanline | you can follow the trace from pin 17 to a via |
| 22:40:56 | scanline | pin 18's trace goes under the chip, but it connects to the opposite side of that capacitor from the one pin 17 connects to |
| 22:41:27 | Tangent | scanline : OK.. give me a second, and I'll hook up the 3.3v to the right place... |
| 22:43:52 | scanline | UNIX really needs a spork() function... |
| 22:44:08 | Tangent | scanline : OK.. pin17 hooked to the Speaker Voltage pad... |
| 22:44:52 | scanline | cool |
| 22:45:56 | scanline | hi file |
| 22:46:05 | GPSFan | Tangent: next is the wires from the other header on the shanip |
| 22:46:36 | scanline | I'll be back in an hour or so... |
| 22:46:40 | scanline | is away: class |
| 22:46:52 | file | you have a weird schedule scanline. |
| 22:47:03 | scanline | 5PM lecture |
| 22:47:10 | file | ahhh |
| 22:47:14 | file | hurry then. |
| 22:47:19 | file | although you got 10 minutes. |
| 22:47:30 | GPSFan | Tangent: the ucb.jpg is now updated to show the 3.3V connection. |
| 22:47:31 | scanline | I live really close to the engineering building... |
| 22:47:32 | Tangent | GPSFan : OK.. I've done the frame ans signal grounds to the pads just under C314 |
| 22:47:41 | file | uh huh |
| 22:47:53 | file | scanline: when should I expect ickysneeze back? |
| 22:47:56 | GPSFan | Tangent: ok |
| 22:48:05 | Tangent | GPSFan : Cool.. That's the connection I did.. (In the jpg) |
| 22:48:09 | scanline | file: i don't know. bye... |
| 22:48:24 | GPSFan | ;>) |
| 22:48:30 | Tangent | GPSFan : So now I've just got the other header to do |
| 22:51:15 | GPSFan | Tangent: pic updated again showing ground. |
| 22:51:38 | Tangent | GPSFan : Yep.. that's the ground I got |
| 22:51:45 | GPSFan | ;>) |
| 22:51:54 | prpplague | GPSFan: whats the url? |
| 22:52:11 | GPSFan | Tangent: the next set of wires is shown on http://tuxscreen.net/download/schematics/emain66by.jpg |
| 22:52:36 | GPSFan | Tangent: except for the green wire which now goes to the circled pad. |
| 22:52:39 | Tangent | GPSFan : Yeah.. the wires are shown, but I don't know which is which.. |
| 22:53:21 | GPSFan | Tangent: ok the black is ground, the green isIC500-13 |
| 22:54:20 | GPSFan | Tangent: yellow is TROUT+ grey is TROUT- |
| 22:54:57 | Tangent | GPSFan : I wish he'd moved the cables from the RJ11 connector when he too those pics |
| 22:55:23 | GPSFan | tan: he wanted us to suffer... |
| 22:55:55 | Tangent | GPSFan : You're not wrong |
| 22:56:16 | GPSFan | did you see the original pic, is was so dark you could hardly see anything. |
| 22:56:54 | GPSFan | I should re-do that pic. maybe later this evening |
| 22:56:58 | prpplague | GPSFan: so what does this mod do? i've have been follow your work |
| 22:57:06 | Tangent | GPSFan : I'll snap this one in a sec |
| 22:57:26 | Tangent | GPSFan : So green has moved to the red circle? |
| 22:58:03 | GPSFan | Tangent: yes, that is how we got rid of the cruddy audio and interference with the phone line. |
| 22:58:31 | GPSFan | prpplague: this is an implementation of shanip2 using Tangent's PCB. |
| 22:59:14 | file | decides to part the channel... |
| 22:59:23 | GPSFan | prpplague: I'm just walking him through it due to my poor doc's, and the fact that scanline did it at 1:am. |
| 23:02:56 | SteveD_away | log |
| 23:03:41 | Tangent | GPSFan : Piccies uploading now |
| 23:08:06 | GPSFan | Tangent: new pic with updated #s: http://tuxscreen.net/download/schematics/emain66by.jpg |
| 23:08:57 | GPSFan | Tangent: that's still using the Lucent color code, I'll re-do it with signal names later. |
| 23:09:28 | GPSFan | Tangent: I've got to go for a bit, bbiaw |
| 23:10:04 | Tangent | Aw shucks... I still have no idea how to test this... |
| 23:20:52 | Tangent | http://ipaq.secret.org.uk/TuxScreen/Shanip-BottConn.jpg http://ipaq.secret.org.uk/TuxScreen/Shanip-TopConn.jpg |
| 23:23:08 | Tangent | How do I get a happy tone now? |
| 23:23:09 | CosmicPenguin | buhbye all |
| 23:24:37 | BZFlag | Tangent: you have ssh SF access? You can put images up there. (hint) |
| 23:25:01 | Tangent | BZFlag : Do I have SF access? I don't know about it if I have |
| 23:31:21 | GoRK | hello |
| 23:32:37 | Tangent | GoRK : Hi |
| 23:34:27 | GoRK | i have bits coming from mouser by the end of the week.. hopefully ill be able to make up about 10 of these boards |
| 23:34:57 | BZFlag | Tangent: sf account name? |
| 23:35:08 | Tangent | BZFlag : Tangent would be good |
| 23:35:11 | pattieja | is away: MOSLUG |
| 23:36:09 | BZFlag | Tangent is "Pat", somehow I doubt that's you. |
| 23:36:30 | Tangent | BZFlag : Yeah.. that doesn't sound like me |
| 23:37:02 | BZFlag | If you have never reqested a SF account you will need to go through the free registration. then send me your account name and I can get you CVS/ssh write access. |
| 23:37:38 | BZFlag | Tangent: what's your last name? Jim ... ? |
| 23:37:46 | Tangent | BZFlag : Conner |
| 23:37:54 | BZFlag | oh, yeah. sorry. looking... |
| 23:38:07 | AlHazWork | goes home |
| 23:39:35 | BZFlag | there are two Jim Conners: notjames and carokann, not you right? looks like you need to get a new account. |
| 23:40:17 | Tangent | BZFlag : Like I say.. If I had an account I never knew about it.. I've never tried to set one up |
| 23:40:35 | BZFlag | do it now. ;-) |
| 23:41:39 | GoRK | any new words on the kernel? |
| 23:42:13 | GoRK | i tried russ's latest 2.4.13 patch with jffs and got the same oopses and crash on mounting... im not sure it's just a jffs2 remount problem |
| 23:42:23 | Tangent | GPSFan : Check your scroll buffer for the piccies I posted |
| 23:42:29 | GoRK | i mean i tried it with both jffs2 and jffs |
| 23:42:41 | GPSFan | Tangent: you have a wire goint to pin 1 of J500 |
| 23:43:05 | Tangent | BZFlag : OK.. I've registered... I'm jac11 |
| 23:43:11 | BZFlag | GoRK: you could turn off the fb and ucb1200 drivers and see what happens with just serial. |
| 23:43:32 | GoRK | BZFlag: to see if that is causing it you mean?' |
| 23:43:37 | Tangent | GPSFan : You asking, or telling? and is that good or bad? |
| 23:43:56 | GPSFan | Tangent: I believe it should go to pin 3 |
| 23:44:13 | Tangent | GPSFan : Ah.. OK.. I'll have to rip the screws out again |
| 23:44:43 | Tangent | warns up the iron |
| 23:44:54 | BZFlag | Tangent: "jac11" ? does not show up yet. ping me on it later. |
| 23:46:10 | GPSFan | Tangent: Yep, the wire going to the first pin in the row should really go to the second. my pic still isn't clear enough, I'll try and fix it tonight. |
| 23:46:32 | Tangent | GPSFan : I'll take another snap when I've moved the wire |
| 23:46:54 | GPSFan | ok, I'm off to dinner ,be back an a bit. |
| 23:51:13 | scanline | is back (gone 01:04:33) |
| 23:51:51 | Tangent | Doh... /me forgot to take pictures |
