| 00:11:38 | andersee | is away: I'm busy |
| 00:14:24 | scanline | is away: food... bbl |
| 00:16:01 | Niddix | Russ: It appears that the check that is the problem is packet.udp.dest != htons(CLIENT_PORT) |
| 00:16:45 | Niddix | Russ: Ocassionally packet.ip.protocol != IPPROTO_UDP fails but thats probably some broadcast packet. |
| 00:27:26 | EGg0 | is away: Gotta pack. |
| 00:29:17 | Niddix | Russ: Well if I ignore the CLIENT_PORT, then ntohs(packet.ip.tot_len) != bytes |
| 00:34:11 | Tangent | does the victory dance... got my new PIC to PIC comms routines working |
| 00:42:22 | Niddix | high fives tangent |
| 00:42:33 | Tangent | Niddix : thanks :) |
| 00:49:28 | Niddix | Tangent: I've been looking around for DIY X10 kits to no avail. |
| 00:49:35 | BZFlag | Russ: is there a way to determine if udhcpc is in -q mode inside the script? |
| 00:50:03 | pattieja | is away: home |
| 00:50:25 | Tangent | Niddix : you should build one of these boards I made.. it's dead cool :) |
| 00:50:49 | Niddix | Tangent: Well the idea of not needing control wires is compelling. |
| 00:51:21 | Niddix | Tangent: I think I'd actually like something that signals the controlls over the grid. |
| 00:51:23 | Tangent | Niddix : I still need control wires... unless I'm using an 802.11 device to interface to it all |
| 00:51:56 | Tangent | Niddix : Nod... I may have a go at a powerline interface soon... but I'm not impressed with X10 generally |
| 00:52:07 | Niddix | Tangent: Why not? |
| 00:52:20 | Tangent | Niddix : Too slow... not reliable etc |
| 00:52:30 | scanline | is back (gone 00:38:06) |
| 00:53:14 | Niddix | Tangent: Why not go with a bunch of little Arms and power based ethernet ;) |
| 00:53:16 | Tangent | Niddix : Also, X10 stuff is somewhat lacking in the UK |
| 00:53:39 | Tangent | Niddix : Arms to control it all.. PICs to do all the interfacing :) |
| 00:53:48 | Tangent | Niddix : That's the actual plan :) |
| 00:54:15 | Niddix | Tangent: Well I was actually talking about a little arm in each switch ;) |
| 00:54:34 | Tangent | Niddix : Nod.. I know... It'll be PICs doing that job tho |
| 00:54:39 | Niddix | Tangent: And when they weren't doing anything they could be running Setti ;) |
| 00:54:58 | Tangent | crunchind DES keys |
| 00:55:07 | Niddix | Targent: Just think of all the distributed processing power you'd have in the house. |
| 00:55:30 | Niddix | Tangent: Knowing my luck the damn thing would become sentient and decide I couldn't live there anymore. |
| 00:56:24 | Niddix | Tangent: What is a PIC exactly? |
| 00:56:30 | Tangent | Niddix : If it happened, you'd be a rich rich man |
| 00:57:07 | Tangent | Niddix : Programmable interface controller... little CPU with high current I/O... 1K to 8K flash, few hundred bytes of ram, few hundred bytes of eeprom |
| 00:57:52 | Niddix | Tangent: I see, so its basically a special purpose CPU. |
| 00:58:50 | Tangent | Niddix : Actually a very general purpose CPU |
| 00:59:12 | Tangent | Niddix : There's one in my aircon, microwave, diswasher, washing machine, oscilliscope etc |
| 00:59:43 | Tangent | Niddix : here's the specific chips I'm using... http://www.microchip.com/download/lit/pline/picmicro/families/16f87x/30292c.pdf |
| 00:59:43 | Niddix | Tangent: Well I guess what I meant was in the end.. its special purpose once its programmed. |
| 01:00:00 | Tangent | Niddix : You can upload new code over the serial port :) |
| 01:00:33 | Tangent | Niddix : And the higher end models are capable of reprogramming themselves, so you can play with genetic code etc :) |
| 01:00:33 | Niddix | Tangent: I am currently looking at http://www.brouhaha.com/~eric/pic/chips.html |
| 01:01:03 | Tangent | Niddix : They're all the C series chips.. They're all only one-time programmable |
| 01:01:17 | Tangent | Niddix : The F series chips are all flash based, and much more fun |
| 01:02:00 | Tangent | Niddix : I started out with a bit of X10 stuff... (4 appliance modules, 4 lamp modules, 2 itmers, 2 PC interfaces), but found it very limited |
| 01:02:56 | Tangent | Niddix : So I bought a couple of kit boxes to interface my PC to the real world.. a parallel port based Data acquisition unit, a serial based temperature logger with 4 inputs, and a serial based relay box... and hooked them up to a PC |
| 01:02:58 | Niddix | Tangent: I bought a couple of RF lights and switches when our local Lowes moved and decided to mark everything down 50% |
| 01:03:20 | Tangent | Niddix : The X10 stuff I got was at something like 70% discount |
| 01:04:09 | Niddix | Tangent: Right now your control wires are lowvoltage? |
| 01:04:44 | Tangent | Niddix : I'll continue my little story |
| 01:05:05 | Tangent | Niddix : The serial relay box has 10A mains rated relays, so I'm using that to control the lights in my office |
| 01:05:54 | Tangent | Niddix : The DigitalIO box has digital inputs & outputs, and analog inputs and 1 analog output.. that's controlling another set of relays, and reading back battery voltage, solarpanel voltage etc |
| 01:06:06 | Tangent | Niddix : There's also the X10 stuff... |
| 01:06:43 | Tangent | Niddix : Having a PC with 3 serial ports + parallel port in use kinds sucked, and I wanted to be able to do all this from the tuxscreen |
| 01:07:15 | Tangent | Niddix : So I built a PCB with a couple of PIC chips on it to take all the modules, and make it into a single serial port for the tux to control |
| 01:07:42 | Tangent | Niddix : The PICs I'm using have built in UARTs, so it's dead easy :) |
| 01:09:34 | Niddix | Tangent: So what you just got working was the PICS controlling all that other jaz? |
| 01:10:19 | Tangent | Niddix : Nope.. had that working for a month or so now... I just upgraded my chip-to-chip comms routine to be about twice as fast, and 99.99% more reliable |
| 01:12:02 | Arc_Tangnet | Huh |
| 01:12:55 | Tangent | Niddix : I plan to add a load more chips and plug in my three UPS's too |
| 01:14:14 | Niddix | Tangent: I'm getting ready to start building a house. At the core there will be a battery system that will be sized to run the house (not the dryer and the like however) for several hours. |
| 01:14:45 | Tangent | Niddix : That's what the second set of relays are for in my system.. they switch between inverter or mains for the lights |
| 01:14:51 | Niddix | Tangent: It will also have solar, and probably some hydro electric generation capability. |
| 01:15:09 | Tangent | Niddix : That way I can use free energy when it's available, without needing a full grid-connected system |
| 01:15:18 | Niddix | Tangent: Nod. |
| 01:15:36 | Tangent | Niddix : I only have 106w Solay and 90AH battery :( |
| 01:15:42 | Niddix | Tangent: It would be great to automatically be able to shut off certain things if the grid went offline,. |
| 01:15:46 | Tangent | Gives me about 6-8 hours of lighting tho |
| 01:16:07 | Tangent | Niddix : Nod.. That's also why I want a tux to control it... the tux draws only a couple of watts |
| 01:16:30 | Niddix | Niddix: Yeah, I bought my tux to control the system. |
| 01:16:35 | Tangent | Niddix : Me and my mate are working on an architecture where you can have multiple guis on different devices |
| 01:17:25 | Tangent | Niddix : So you can lie on the sofa, and dim the lights with your iPAQ over 802.11, or sit at an Xsession, or use a Tux, or a telnet session etc |
| 01:17:53 | Tangent | Niddix : Also working on a nice drag&drop control language for it |
| 01:18:17 | Tangent | Niddix : have you seen the photos of this btw? |
| 01:18:24 | Niddix | says, "Computer, please turn off the lights in the workshop." |
| 01:18:40 | Niddix | Tangent: Of your board? Yeah I've seen em. |
| 01:18:54 | Tangent | Niddix : Yeah.. the voice activated stuff I want to do too :) |
| 01:19:34 | Niddix | Tangent: I also want to have an infrared senor at the front gate. Which is incidently almost 600 feet from the house. |
| 01:19:54 | Niddix | s/senor/sensor |
| 01:20:38 | Tangent | Niddix : Sounds like a job for a wireless link of some kind |
| 01:20:46 | Niddix | Tangent: I always get annoyed when someone knocks on my door. I mean I live in the middle of nowhere and you have to walk down a long driveway to get to my house. |
| 01:21:11 | Tangent | Niddix : You also want the camera there too then |
| 01:21:18 | Tangent | Niddix : See who it is before they get there |
| 01:21:46 | Niddix | Tangent: I just put a waterline in from the house that runs up to the garden that is near the gate. I dropped 8 strands of Cat5 cable into the trench. |
| 01:22:04 | Tangent | Niddix : Ah.. then you have no problems |
| 01:22:13 | Niddix | Tangent: Well dropped inside a PVC conduit. |
| 01:22:29 | Tangent | Niddix : My chip to chip protocol is designed to cope with that :) |
| 01:22:39 | Niddix | Tangent: I've also got a 14AMP powerline down there as well. |
| 01:23:09 | Niddix | Tangent: That was expensive to put the nonrigid metal conduit in there. |
| 01:23:16 | Tangent | Niddix : Plenty of power and data capability there :) |
| 01:23:29 | Niddix | Tangent: I'm just worried about interference. |
| 01:23:47 | Tangent | Niddix : Nod, but that's the point of twisted pairs and differential drive |
| 01:23:52 | Niddix | Tangent: The power is about 3 feet deep and the Cat5 is about a foot above that. |
| 01:24:07 | Tangent | Niddix : So you have a foot of earth between them? |
| 01:24:11 | andersee | is back (gone 01:12:31) |
| 01:24:17 | Niddix | Tangent: roughly.. |
| 01:24:23 | Tangent | Niddix : Should be fine |
| 01:24:24 | Niddix | Tangent: Maybe not quite in all places. |
| 01:24:36 | Niddix | Tangent and the water line between them as well. |
| 01:24:57 | Tangent | Niddix : I doubt if you'll get any interference on that at all :) |
| 01:25:26 | Niddix | Tangent: My wife thought I was nuts when I put the Cat5 in there. |
| 01:25:37 | Tangent | Niddix : Pah |
| 01:26:03 | Tangent | Niddix : She'll come to appreciate it when it's all done :) |
| 01:26:13 | Niddix | Tangent: Heh.. one can always dream. |
| 01:28:04 | Niddix | Tangent: I've got a project for a class I need to finish up. |
| 01:29:03 | Tangent | Niddix : What kind of project? |
| 01:29:52 | Niddix | Tangent: Oh I've got to come up with a Layered Protocol for communication between people. Sort of like the OSI |
| 01:30:27 | Tangent | Niddix : I take it you've seen the avion carrier protocol |
| 01:30:29 | andersee | What will you use for the physical layer? |
| 01:30:35 | andersee | ;-) |
| 01:31:16 | Niddix | Tangent: Carrier Pigeon? |
| 01:31:22 | Niddix | andersee ;) |
| 01:31:35 | Tangent | Niddix : That's the one.. there's an RFC for sending IP packets via pidgeons |
| 01:31:51 | Niddix | Tangent: Yeah I think I've read that one. |
| 01:32:14 | Niddix | Tangent: Talk about latency. |
| 01:33:00 | Niddix | Tangent: I would suppose that Carrier Pigeon would fit into the transport layer. |
| 01:33:41 | Niddix | I hate IS courses. |
| 01:34:09 | Niddix | I actually had an argument with my teacher when he told the class that access was an example of a non-relational database. |
| 01:34:46 | Niddix | And he kept interchanging the terms "flat-file" and "non-relational". |
| 01:34:52 | Niddix | sighs |
| 01:35:13 | Tangent | Niddix : I had a similar argument with a teacher who told us to write code to do a binary search on a linked list... it lasted two hours and he eventually gave in after someone wrote the code and showed him how dumb it was |
| 01:36:17 | Niddix | Tangent: It was like he read a few articles and maybe had seen a picture of the box that Access comes in. |
| 01:37:16 | Niddix | Tangent: It was painfully obvious he had never looked at even the simplest of sample databases that comes with it. |
| 01:37:42 | Niddix | Tangent: Either that or he has no clue what a relational database is. |
| 01:38:00 | Tangent | Niddix : And you you have to learn the incorrect rubbish they teach, because they set the exams too |
| 01:38:17 | Niddix | Tangent: He kept using Oracle, Sybase and SQL Server of course as examples of relational databases. |
| 01:38:17 | Tangent | s/you you/yet you/ |
| 01:38:34 | Niddix | Tangent: And Dbase, Paradox, Access, etc as non-relational. |
| 01:38:52 | Niddix | Tangent: I wanted to strangle him. |
| 01:39:31 | Niddix | Tangent: What any of this has to do with a tuxphone is beyond me. |
| 01:41:50 | Sammy | hi |
| 01:42:02 | Tangent | Sammy : Evening |
| 02:05:07 | Niddix | Ok thats done. |
| 02:08:26 | Niddix | How hard is it to mount a filesystem over a serial line? |
| 02:12:39 | Tangent | Niddix : PPP+NFS ... not too bad |
| 02:37:28 | BZFlag | Niddix: you are not planning on making your tux an oracle server? ;-) |
| 02:37:31 | BZFlag | nite all |
| 03:05:59 | Russ | Returns |
| 04:03:51 | Morn | Hi, been a while since I was here |
| 04:04:27 | sjm | Hi, How's things? |
| 04:04:55 | Morn | tis ok... just wondering how things are coming... I still haven't gotten around to putting linux on my phone |
| 04:05:08 | Morn | been kinda busy, since I moved out of Manhattan to CT |
| 04:05:22 | Russ | moving pretty code, still getting userspace up to speed with the new ts driver |
| 04:05:25 | thekernel | I think they have the DSP mostly figured out if not all the way. |
| 04:05:30 | Russ | er, good, not code |
| 04:05:35 | Russ | too much coding... |
| 04:05:39 | Russ | code is good... |
| 04:05:48 | thekernel | is code pretty? |
| 04:05:58 | Russ | unless spacecoaster wrote it |
| 04:06:10 | Morn | Is it in a usable state of I do the install after thanksgiving? |
| 04:06:14 | Russ | he needs to run scripts/Lindent on his stuff |
| 04:06:36 | thekernel | Well, I hope to get my GPS running soon. I did some more work on con-tiger (My datafile converter) |
| 04:13:30 | thekernel | Dead isn't it? |
| 04:14:01 | scanline | listens to Pink Floyd and hacks drivers |
| 04:14:29 | thekernel | listens to Semisonic and eats a burrito |
| 04:14:40 | scanline | that sounds fun too |
| 04:14:45 | scanline | i just had some pop tarts... |
| 04:14:53 | Morn | thinks about ice cream |
| 04:15:05 | thekernel | pop tarts give me heart burn |
| 04:15:09 | scanline | DCCs Morn a chicken pot pie |
| 04:15:16 | scanline | hehe |
| 04:15:23 | scanline | we scared andya away |
| 04:15:26 | thekernel | That's funny |
| 04:15:40 | Morn | scanline: home made chicken pot pie from PA dutch country is great |
| 04:15:53 | scanline | All i have are microwave pot pies... |
| 04:16:02 | scanline | Ramen noodles are always good though |
| 04:16:13 | thekernel | I nuked my burrito, does that count for anything? :) |
| 04:16:22 | scanline | yes... i suppose... |
| 04:16:35 | scanline | Burritos... yum |
| 04:16:40 | Morn | I grew up in Dutch country so that type of food is what I know |
| 04:16:41 | thekernel | They are lynn wilson burritos... |
| 04:16:44 | scanline | curses X11 keysyms |
| 04:17:06 | scanline | I live in a world of microwaved entrees and canned drinks |
| 04:17:14 | thekernel | ncurses :) |
| 04:17:21 | scanline | haha |
| 04:17:24 | scanline | I like ncurses |
| 04:17:37 | thekernel | It's like curses, but newer :) |
| 04:18:25 | thekernel | Who here has used Cosmic's microwindows? |
| 04:18:48 | thekernel | As in his distribution of microwindows (He got after me for being ambigious last time) |
| 04:18:54 | scanline | i've used it some. Haven't coded for it yet |
| 04:19:11 | scanline | yeah, i've used it (though i usually have my head in picogui's internals) |
| 04:20:14 | thekernel | got a mission call (for those who are interested) |
| 04:20:33 | scanline | mission call? |
| 04:20:47 | scanline | curses X11's lack of key repeat events |
| 04:21:03 | thekernel | It's an LDS thing. see lds.org to figure out what I'm talking about |
| 04:21:17 | thekernel | I'm going to Germany |
| 04:21:31 | scanline | oh, that kind of mission |
| 04:21:35 | thekernel | Yeah |
| 04:21:43 | scanline | not Mission Impossible kind of mission :) |
| 04:21:48 | Morn | my room mate used to be a Mormon |
| 04:21:54 | Morn | she left the faith though |
| 04:22:08 | thekernel | It happens all the time |
| 04:23:33 | Morn | She wants to go back to SLC though for the olympics and to visit friends this winter |
| 04:23:52 | thekernel | I'll be leaving just in time to miss the olympics |
| 04:23:58 | thekernel | lives in SLC |
| 04:24:10 | Morn | I have been there 3 times |
| 04:24:17 | thekernel | I have been here too long :) |
| 04:24:18 | Morn | went bunji jumping the one time |
| 04:25:43 | thekernel | Before I come home from germany I'm going to observe the political climate. If it's better to be a free software programmer out of the states than in I would consider going back for an extened stay |
| 04:26:41 | thekernel | I'll jump ship if the land of the free stop being that way with the tech industry. |
| 04:31:39 | Morn | fiddles with the ultra sparc some more |
| 04:54:03 | sjm | lunch time |
| 04:57:16 | scanline | Is anyone here familiar with Xlib programming? I don't know how to get repeated keys |
| 05:10:18 | raybass | russ |
| 05:10:21 | raybass | needs help |
| 05:11:15 | scanline | figures out X keyboard events |
| 05:11:17 | scanline | yay |
| 05:52:05 | jacques | ugh |
| 09:59:34 | little_kid | How do I again get a list of who's "in" -online? (no not by using pge up). |
| 15:06:52 | jacques | anyone awake? |
| 15:07:01 | Morn | kinda :-) |
| 15:07:11 | jacques | 2,4,13 kernel is not working for me - hangs on "mounting local file systems:" |
| 15:07:28 | Morn | sorry, I can't help |
| 15:07:35 | Tangent | jacques : When I tried it last, mount was getting stuck in D state |
| 15:07:51 | jacques | Tangent: what that mean? |
| 15:07:58 | jacques | Tangent: and how you determine that? |
| 15:08:02 | jacques | Tangent: and when was that? |
| 15:08:03 | Tangent | jacques : There's a line in the fstab/linuxrc that remounts a filesystem... if you comment it out, it'll stop hanging |
| 15:08:21 | jacques | Tangent: oooh, please elaborate |
| 15:08:21 | Tangent | jacques : I determined it becasue Russ talked me through the kernel sysrq stuff |
| 15:09:01 | Tangent | jacques : I can't elaborate... I overheard a conversation where someone said that they'd fixed it by commenting out a line where the filesystems gets remounted ro or rw |
| 15:10:21 | jacques | so the line is unnecessary? |
| 15:11:18 | jacques | Tangent: does it only happen to some ppl? why was it not found in testing? |
| 15:13:44 | Tangent | jacques : I think it happens to everyone who has tried 2.4.13 |
| 15:13:52 | Tangent | jacques : Russ would know |
| 15:15:32 | jacques | Tangent: ok, thanks. I'm going to wait til it's fixed i guess |
| 15:16:34 | jacques | Tangent: I saw conversation earlier which said they found and fixed the problem - it was in mtd - and it's in cvs |
| 15:16:48 | jacques | but not in the latest kernel source yet - mtd cvs |
| 15:19:20 | jacques | hmm, I cant find the remount |
| 15:20:08 | pattieja | is back (gone 14:30:03) |
| 15:26:52 | Niddix | Try getting the latest mtd snapshot. |
| 15:27:28 | CosmicPenguin | morning all |
| 15:27:52 | jacques | Niddix: ok - I will be happy to try it - do you have a pointer for me? |
| 15:28:02 | Niddix | Morning CosmicPenguin. |
| 15:28:43 | Niddix | jacques: I can't recall.. look in the buildroot-tux Makefile.. search for MTD.. make it 1120 instead of 1115 |
| 15:29:02 | jacques | Niddix: clever |
| 15:29:08 | Niddix | jacques: Supposedly the fix to mtd was put in at like 3:00am yesterday. |
| 15:29:53 | Niddix | jacques: I have not tried it yet, so I can't tell you it will work. |
| 15:30:31 | jacques | Niddix: is the mtd stuff applied to the kernel or the root image? |
| 15:30:59 | Niddix | jacques: as far as I know its a loaded module, so it would be in the root image. |
| 15:31:14 | jacques | Niddix: ok, thanks |
| 15:31:49 | Niddix | jacques: Of course you might want to reflash the kernel just to be safe :) |
| 15:33:15 | jacques | Niddix: well... |
| 15:33:22 | jacques | Niddix: buildroot is extremely fragile |
| 15:33:35 | jacques | i broke it badly trying to get it to build the 2.4.13 kernel |
| 15:33:51 | jacques | so I built that manually and just let it build 2.4.7 but flashed 2.4.13 |
| 15:35:49 | Niddix | jacques: I haven't tried building the 2.4.13 kernel yet. |
| 15:37:04 | jacques | only thing I noticed about 2.4.13 is that the backlight is screwey compared to 2.4.7 - very uneven |
| 15:37:26 | jacques | not that I could tell much since it wouldn't boot |
| 15:37:38 | Niddix | ;) |
| 15:37:46 | jacques | uh-oh |
| 15:38:21 | jacques | I think I do have to do something with the kernel because someone said something about russ needing to make a new kernel source for this to be fixed |
| 15:38:25 | Niddix | jacques: That doesn't sound good. |
| 15:41:19 | jacques | yeah :-\ |
| 15:49:28 | jacques | hmm, this might not be so hard |
| 15:49:50 | jacques | there is a script which patches the mtd stuff into the kernel source tree |
| 15:51:06 | jacques | i need a faster computer |
| 15:51:28 | jacques | i dont like waiting for things to compile |
| 15:55:37 | Niddix | ;) |
| 15:58:30 | jacques | hmmm |
| 15:58:36 | jacques | i made it worse |
| 15:58:49 | jacques | i think there's something I'm missing |
| 16:02:44 | jacques | this looks particularly incorrect: |
| 16:02:48 | jacques | SA1100 flash: probing 32-bit flash bus |

| 16:02:48 | jacques | number of CFI chips: 1 |
| 16:02:48 | jacques | SA1100 flash: no partition info available, registering whole flash at once |
| 16:47:26 | jacques | so, how long til the modem in the tuxscreen is working? :-D |
| 16:53:41 | jacques | has anyone run MAME on the tuxscreen? |
| 16:54:23 | CosmicPenguin | jacques: There is no modem (it will be a softmodem).... as for mame, I am sure one of the X folks has fired it up |
| 16:55:19 | jacques | CosmicPenguin: the modem uses the dsp, right? |
| 16:55:45 | jacques | CosmicPenguin: that's what I meant - or are you saying that the modem code is downloaded to the dsp at boot and we dont have the code? |
| 16:56:03 | CosmicPenguin | jacques: I don't believe that the DSP has any modem capabilities at all.... |
| 16:56:25 | jacques | CosmicPenguin: you are saying that the SA1100 was doing the modem work? |
| 16:56:37 | CosmicPenguin | jacques: No, we think that the UCB1200 was getting involved.... |
| 16:57:00 | | somebody said ucb1200 was at the other end of a fifo, (8 or 12 bytes), what data rate is the audio? |
| 16:57:00 | jacques | ibot: ucb1200 |
| 16:57:11 | CosmicPenguin | stupid bot... |
| 16:57:31 | jacques | CosmicPenguin: so are you saying there is very little chance of getting modem functionality working under linux? |
| 16:57:40 | CosmicPenguin | jacques: The UCB1200 is a digital to analog chip that controls various things like the sound, the touchscreen and the telecom.... |
| 16:58:05 | CosmicPenguin | jacques: No, there is a very good chance of getting the modem functionality working, we just need a little more time, and a good softmodem implementation |
| 16:58:21 | jacques | CosmicPenguin: ah, that's what I thought the dsp was doing - what did it do? |
| 16:58:28 | jacques | CosmicPenguin: :-D cool |
| 16:59:11 | CosmicPenguin | jacques: The DSP handles the most of the Telco specific functions as well as the interface to the "phone" part of the system (keypad, handset, etc, etc...) |
| 16:59:22 | jacques | CosmicPenguin: in playing with the "message" program under microwindows, I am realizing that this would make a great toy |
| 16:59:28 | CosmicPenguin | jacques: How so> |
| 16:59:42 | jacques | CosmicPenguin: it's like an electronic coloring book |
| 17:00:17 | CosmicPenguin | jacques: Thats true... it wouldn't be too hard to bring in an image and set it as the background.... |
| 17:00:24 | jacques | I know that's not what it's meant to be, and it needs a lot of work - it does not poll nearly often enough |
| 17:00:44 | jacques | the drawing program under inferno was much better at following the stylus |
| 17:00:53 | CosmicPenguin | jacques: Its painful, because Microwindows doesn't support line widths, so the speed hits you see is because I am reimplementing breshingham in user space |
| 17:01:21 | jacques | CosmicPenguin: ah, sorry if I offended withthe needs work comment - I didn't know you did it |
| 17:01:24 | CosmicPenguin | jacques: I have fixed it a little bit, but I still have to implement line widths on the Microwindows server.... |
| 17:01:39 | CosmicPenguin | jacques: No offense... |
| 17:02:20 | jacques | microwindows looks really good on the tuxscreen |
| 17:02:41 | jacques | it's almost like they went out of their way with the GUI over inferno to make it look bad |
| 17:02:54 | CosmicPenguin | jacques: thanks.... It really needs a artist's touch though..... :) |
| 17:03:12 | CosmicPenguin | jacques: I think thats a combination of old technology and them having to fit it in 3 or 4 MB of space... |
| 17:03:52 | jacques | CosmicPenguin: and tk :-D |
| 17:05:15 | jacques | CosmicPenguin: microwindows is accessing the frame buffer directly? |
| 17:08:17 | jacques | I'm surprised there's not a port of MAME to microwindows |
| 17:11:49 | CosmicPenguin | jacques: There is... :) |
| 17:12:08 | CosmicPenguin | jacques: But it is fairly old... last Xmas if I recall..... |
| 17:13:08 | jacques | CosmicPenguin: well it's not like the tuxscreen has the CPU power or RAm to play the latest games :-) |
| 17:13:19 | jacques | CosmicPenguin: I'm thinking pacman |
| 17:13:24 | CosmicPenguin | It might look alirght..... Mame is working very well on the Ipaq.... |
| 17:13:40 | CosmicPenguin | jacques: I'll try to get it working here presently... I'll have to stick it on a CF though.... |
| 17:14:27 | jacques | CosmicPenguin: yeah, the binary is huge - I can use my microdrive for testing but want to move to CF |
| 17:14:45 | CosmicPenguin | Sams Club has a 128MB cf for $54 bucks! |
| 17:14:52 | jacques | CosmicPenguin: whoah |
| 17:15:08 | CosmicPenguin | Thats more than the combined storage of my first 4 computers! |
| 17:15:35 | jacques | I have a 64MB and an 8MB CF |
| 17:15:42 | jacques | but the 64MB is in my camera |
| 17:16:31 | jacques | it's too bad SODIMMs are so expensive |
| 17:16:38 | CosmicPenguin | *shrug* |
| 17:16:56 | jacques | i could really use 32MB of ram |
| 17:17:38 | Tangent | jacques : I know the feeling |
| 17:17:44 | Tangent | jacques : Having 32M of swap helps tho ;) |
| 17:18:22 | jacques | Tangent: I'm running 64MB swap these days |
| 17:18:44 | Tangent | jacques : You must seriously hammer that poor little machine |
| 17:19:02 | jacques | Tangent: compiling glibc and xfree will do it |
| 17:19:41 | Tangent | jacques : Yep... I can believe that... for that matter, compiling qt is pretty hard for it too |
| 17:20:04 | jacques | Tangent: actually those are on my ipaq - I'm not sure I would want to try it with only 16MB ram |
| 17:20:21 | Tangent | jacques : Nod.. i figured we were talking iPAQ |
| 17:21:24 | jacques | I can't believe how much money crucual wants for a 32MB SODIMM |
| 17:21:29 | jacques | crucial |
| 17:21:37 | Tangent | jacques : How much they asking? |
| 17:21:44 | jacques | they are really taking advantage of corporations |
| 17:21:53 | jacques | Tangent: > $42 |
| 17:22:01 | Tangent | jacques : I'd pay that |
| 17:22:31 | jacques | Tangent: I can get 512MB SDRAM for that price |
| 17:23:07 | jacques | Tangent: I would buy some too, but I am pissed off at hearing how they keep substituting parts on people |
| 17:23:17 | jacques | that really pisses me off |
| 17:23:58 | Morn | I have one of the crucial 32MB SODIMMS |
| 17:24:07 | Morn | haven't installed it yet though |
| 17:24:31 | boodle | jacques: just sent back the wrong one to them |
| 17:24:32 | jacques | Morn: did you get the part you ordered the first time? without having to RMA it and yell at someone? |
| 17:24:41 | Morn | Yes |
| 17:25:02 | Morn | I actually ordered in like July |
| 17:25:02 | jacques | Morn: maybe they are learning - did you put any special instructions in your order? order over the phone? |
| 17:25:08 | jacques | Morn: ah |
| 17:25:17 | Morn | just didn't put it in because there was no support for it yet then |
| 17:25:18 | jacques | Morn: so you are from before the substitutions |
| 17:25:34 | Morn | I ordered over the internet |
| 17:26:03 | Morn | as soon as I have a 12v power supply though I'm gonna try the linux install on the phone |
| 17:26:03 | jacques | I wish we could do a group buy or something |
| 17:26:17 | jacques | Morn: are you in the US? |
| 17:26:25 | Morn | which pcmcia cards are supported now? |
| 17:26:29 | Morn | Yes, CT |
| 17:27:11 | jacques | Morn: go to the store and buy a A23 battery - for car alarm remotes - tiny little batt that looks like a short AAA |
| 17:27:22 | jacques | Morn: 2 will cost you about $2.49 |
| 17:27:30 | Morn | really? Ok |
| 17:27:34 | Morn | thanks for the info |
| 17:27:45 | jacques | Morn: it has worked great for me - did 2 phones so far |
| 17:28:01 | jacques | Morn: both energizer and duracell make them |
| 17:28:08 | Morn | If this works out well, I'm gonna order a second phone for my housemate |
| 17:28:12 | Morn | :-) |
| 17:28:40 | Morn | she still thinks running linux on your phone is a little odd |
| 17:29:27 | jacques | Morn: the 12V is only used as a signal - you don't need any real power capacity on your 12V source |
| 17:29:39 | Morn | oh, ok |
| 17:29:50 | jacques | Morn: I'm thinking about ordering more and giving them as christmas presents :-) |
| 17:29:51 | Morn | I thought I needed some sort of power |
| 17:30:07 | jacques | Morn: no, I thought that too |
| 17:30:23 | Morn | I was going to get a voltage regulator and set it to 12v |
| 17:30:30 | Morn | guess that would be overkill |
| 17:31:38 | jacques | Morn: I was going to use a small PC power supply |
| 17:32:09 | Morn | you just have to apply the 12v once right? once you unlock the flash rom it's unlocked... |
| 17:32:39 | jacques | Morn: correct |
| 17:33:02 | Morn | I'm building a new workstation/server today (dual athlon) |
| 17:33:17 | Morn | just waiting for UPS to deliver the silly motherboard |
| 17:33:54 | jacques | Morn: I envy you |
| 17:34:21 | Morn | Everyone is drooling over this system... dual athlon 2gig ram 100gig hd high end video and sound dvd |
| 17:36:35 | Morn | the ultra sparc I have is causing a stir too |
| 17:37:52 | jacques | Morn: i really want a dual athlon |
| 17:39:03 | Morn | This is a dual Athlon MP 1.4Ghz |
| 17:39:27 | jacques | top of the line |
| 17:39:42 | Morn | linux is gonna work great on it |
| 17:40:08 | Morn | I was joking with someone I could practically put all the system files on a ram disk with 2gig of ram |
| 17:40:15 | jacques | true |
| 17:42:02 | jacques | too bad the tuxscreen is 8-but |
| 17:42:07 | jacques | 8-bit color |
| 17:42:19 | jacques | I would love to run bbplay on it |
| 17:43:49 | Morn | I just want to get a nic for it so I can have the root partition on a linux server |
| 17:45:20 | jacques | Morn: get a nic for what? |
| 17:45:26 | Morn | the tuxscreen |
| 17:46:33 | jacques | Morn: ah, I got the netgear FA411's |
| 17:46:38 | jacques | they work great |
| 17:46:57 | Morn | I have a spare LinkSys card |
| 17:47:00 | Morn | I'll try that first |
| 17:49:06 | jacques | well, I'm gonna sleep for a bit |
| 17:49:09 | jacques | later |
| 17:49:11 | Morn | have fun |
| 17:49:14 | Morn | nice talking to you |
| 17:49:19 | jacquesZzZz | yeah, same here |
| 20:16:25 | MacAtack | another ot question :) ne1 know a linux utility that will display all Disc I/O activity? (like what files are being read from or written to?) |
| 20:18:02 | Tangent | MacAtack : ls -l /proc/fd/* |
| 20:19:16 | Tangent | MacAtack : ls -l /proc/[0-9]*/fd/* |
| 20:19:40 | MacAtack | you mean s/fd/fs/ ? there is no fd in my /proc |
| 20:19:56 | Tangent | MacAtack : I meant the second line I said |
| 20:20:05 | MacAtack | yeah just saw that |
| 20:22:16 | MacAtack | Tangent: pretty hardcore Thanks!!! |
| 20:22:39 | Tangent | MacAtack : Once of those sneak lines that's worth knowing about :) |
| 20:23:04 | MacAtack | hell yeah.. i saved it for future ref |
| 20:43:53 | MacAtack | Tangent: isn't ls -l /proc/[0-9]*/fd/* basiclly the same thing as lsof ? |
| 20:44:25 | Tangent | MacAtack : Yep.. pretty much |
| 20:45:11 | MacAtack | heh ok... i mentioned that to ~my~ guru and hes like, "dood don't over complicate things just do lsof :)" |
| 20:46:28 | Tangent | Yeah.. lsof is great as long as it's on the filesystem |
| 20:46:48 | spse__ | also handy on solaris |
| 20:46:57 | spse__ | where /proc isnt so featureful (or bloated) |
| 20:51:54 | as_ | Evnin all. |
| 20:52:57 | MacAtack | still afternoon in my neck of the woods :) |
| 20:53:19 | as_ | ;] |
| 21:08:20 | GoRK | greetings |
| 21:09:21 | AlHazWork | hola |
| 21:09:58 | GoRK | ugh i have been sick for like the last 3 days.. what is news? |
| 21:10:13 | AlHazWork | dunno, actually |
| 21:16:10 | MacAtack | hey has anyone ever heard of the tuxscreens being used in the military (Navy)? |
| 21:16:36 | AlHazWork | no, why? |
| 21:17:46 | MacAtack | a friend of mine (coworker acutally) said he saw a show on TLC or discovery about the Navy and he swares a tuxscreen was mounted to the wall behind the captan desk in is quarters (when they were interviewing him) |
| 21:19:55 | AlHazWork | sorta doubtful, it sure aint mil spec |
| 21:20:05 | AlHazWork | could have been the guy's personal property, I guess |
| 21:20:55 | ctr | is away: quick shower |
| 21:22:39 | andersee | GoRK: howdy |
| 21:23:21 | andersee | GoRK: I'm about to try madplay again vs uClibc... I fixed several bugs last night that might fix it... |
| 21:24:37 | andersee | greetings BZ |
| 21:24:59 | andersee | Did you thanks jfree for me? |
| 21:25:07 | GoRK | andersee: cool :) hey i almost have voIP working :) |
| 21:25:22 | andersee | GoRK: excellent!!! |
| 21:26:22 | BZFlag | andersee: nope. have not seen him yet. |
| 21:26:27 | GoRK | andersee: using libiax/asterisk... you could run your own asterisk server or register with iaxtel.com ... at some point asterisk will probably support h.323 and sip as well, so that's why i went with iax |
| 21:26:46 | BZFlag | andersee: he is interested in a DNS swap as well. interested? |
| 21:27:03 | andersee | BZFlag: sure. I think that can be arranged. |
| 21:27:16 | BZFlag | sweet. |
| 21:27:26 | andersee | BZFlag: I payed for busybox.net today. :) |
| 21:27:51 | ctr | is back (gone 00:06:51) |
| 21:27:58 | BZFlag | nice. hey, you should probably explicitly have "notify no;" on slave zones. |
| 21:28:19 | andersee | BZFlag: contributions met the $250 price tag, so I went ahead. I hope the dude actually transfers it to me quickly. |
| 21:28:21 | MacAtack | andersee: is that for the dreamcast shell ? |
| 21:28:22 | BZFlag | I get send you a notify, you pull the domain, and then send me a notify. ;-) |
| 21:28:47 | andersee | BZFlag: ugh. I thought I had that. lemme fix it. |
| 21:28:58 | MacAtack | AlHazWork: ok he's not 100% sure it was a tux but said it looked damn close |
| 21:29:02 | BZFlag | no prob I ignore them anyway. ;-) |
| 21:30:03 | andersee | BZFlag: fixed |
| 21:30:37 | andersee | MacAtack: dreamcast shell? |
| 21:30:40 | AlHazWork | MacAtack: A friend of mine used to be in the navy, was on a destroyer. He said they were allowed computers, but you didn't have much space for them, and it was required that you use a power line filter (and NOT a ups) to protect the ship's power from your computer. |
| 21:30:56 | AlHazWork | if you used a UPS, bad things would happen |
| 21:31:19 | BZFlag | goes to try updating a random domain... |
| 21:32:22 | andersee | GoRK: btw, what did you have to do to make perl 5.6.x compile? Any patches, or just set the PATH and let 'er rip? |
| 21:32:47 | andersee | is about to add perl to the working app list |
| 21:39:36 | GoRK | andersee: um no patches just a lot of fiddling with ./config.pl options.. |
| 21:39:40 | GoRK | err |
| 21:39:43 | GoRK | ./config |
| 21:39:52 | GoRK | or whatever it is that perl used.. some very bizzare system |
| 21:40:43 | andersee | k |
| 21:40:46 | andersee | thx |
| 21:50:09 | AlHazWork | BZFlag: So is the dns thing working well? |
| 21:57:17 | sjm | :q |
| 22:18:33 | bornet | hi |
| 22:18:56 | bornet | i'm interested in the tuxscreen, but i have some questions |
| 22:19:24 | bornet | can it works in Switzerland ? |
| 22:20:45 | dirkx | bornet: I found that the modem/line/phone interface works fine - but had to use a diode to half the european 220v into 110v - which is what the adaptor wants. Alternatively you could buy a 17$ voltage converter/plug convertor. |
| 22:22:59 | as_ | Err, you used a diode to half the voltage? |
| 22:23:19 | as_ | That doesnt make sense... |
| 22:23:41 | Tangent | as_ : It makes sense for driving a switchmode |
| 22:23:53 | Tangent | as_ : Half wave rectify the AC |
| 22:24:12 | as_ | Hmm. |
| 22:24:21 | Tangent | as_ : I agree.. Hmm |
| 22:24:28 | Tangent | as_ : But I think that'd work |
| 22:24:36 | dirkx | ass_: its a bit of a hack :-) but it works just fine. Add a small Cap. and look at it with the scope and it is actually reasonably clean. |
| 22:25:00 | sjm | Got a webpage for this? |
| 22:25:37 | dirkx | Tangent: :-) it works - I've been using US equipment for years whilile living in europe - obviously nothing high power - butthings like a Hub, a little 10/100 switch, a ISDN router, wireless phone, that sort of stuff. |
| 22:26:15 | as_ | I would think youd get the full voltage over the switching transistor. |
| 22:26:15 | Tangent | dirkx : I have a 500VA US feed in my server room for US kit |
| 22:26:30 | Tangent | dirkx : Auto transformer |
| 22:26:31 | as_ | Which it might be able to handle. |
| 22:26:32 | dirkx | sjm: No - but the circutery is simple - just insert 1N14x diode in one of the leads. Done. Do *not* use with switched power supplies of course - only for coil transformer. |
| 22:26:59 | as_ | That makes more sense. |
| 22:27:07 | sjm | dirkx: Hmm... I'll take a look - the same hack might work here is Australia (240V) |
| 22:27:52 | as_ | I would never use that method though. |
| 22:28:19 | as_ | It souds extremely dangerous, particulaly considering power supplies are cheep. |
| 22:28:31 | dirkx | sjm: do you have an AC voltmeter or osciloscope ? In that case it is easy to convince one self. Do attach a load (traditonal Z load -no fluoracnet tubes :-) of course. |
| 22:28:53 | sjm | dirkx: Yep, I'm an EE, so have all that fun stuff :) |
| 22:29:02 | bornet | dirkx: so, you have purchase a 220V power supply, or make your own ? |
| 22:29:03 | dirkx | as_: yes - of course. The proper thing is using a 220v <->110v halving transformer. |
| 22:29:41 | dirkx | bornet: so I simply halved the voltage of italy (which is also 220v) and then fed it into the tuxscreen's adaptor. You can do this several ways. The proper way is to get |
| 22:29:57 | as_ | That doesnt half the voltage. |
| 22:30:02 | GoRK | Russ: hey i am seeing rmk applying these patches :) are there diffs yet for 2.4.15-pre6-rmk2? |
| 22:30:04 | dirkx | an down transformer. They are 17$ or so - i.e. the type you use for traveling. A 'hack' you can use is with a diode. |
| 22:30:05 | as_ | Dont tell people it does. |
| 22:31:11 | bornet | dirkx: so, you need the diode, even with the converter/plug convector ? |
| 22:31:23 | dirkx | as_: I am sorry; but this is simply what I've been doing. And I agree that it does not truly half the voltage - but with a normal Z style load; such as an transformer - it is good enough. But no - you sould not do this for a 10Kwatt load. |
| 22:31:33 | dirkx | bornet: no - it is an OR - OR thing. URL: |
| 22:31:56 | as_ | With a resistive load, it reduces the power consumption to double. |
| 22:32:00 | jacquesZzZz | anyone here using 2.4.13? |
| 22:32:09 | as_ | Wheras without it is running at 4x. |
| 22:32:18 | GoRK | jacques_gone: yes im still on 2.4.13, though i suppose i should upgrade now :) |
| 22:32:27 | jacquesZzZz | GoRK: upgrade to what? |
| 22:32:32 | dirkx | http://www.action-electronics.com/trnsupdn.htm or http://www.dvdoverseas.com/voltage_converters.htm |
| 22:32:43 | jacquesZzZz | GoRK: I am stuck on the mtd mount hang problem |
| 22:32:47 | GoRK | 2.4.15-pre6 or something... |
| 22:32:53 | Tangent | as_ : With a resistive load, it works |
| 22:33:03 | GoRK | jacques_gone: you need to comment out the line in your /etc/fstab for /dev/mdtblock2 |
| 22:33:10 | as_ | Tangent, no it doesnt. |
| 22:33:14 | jacquesZzZz | GoRK: that's all? |
| 22:33:27 | jacquesZzZz | GoRK: it'll still be writable? |
| 22:33:33 | as_ | Power is I^2R or V^2/R. |
| 22:33:38 | GoRK | jacques_gone: yes, the kernel by default mounts up jffs2 as rw |
| 22:33:45 | as_ | Double the voltage, you get x4 the power. |
| 22:33:47 | jacquesZzZz | GoRK: ok, thanks :-) |
| 22:33:51 | GoRK | jacques_gone: if it doesnt just mount -o remount,rw / |
| 22:33:57 | bornet | dirkx: thanks for the URL. I will look at this solution. |
| 22:34:03 | jacquesZzZz | GoRK: I heard there was a fix in mtd cvs |
| 22:34:10 | as_ | Run on half the waveform, and your down to double. |
| 22:34:21 | as_ | It does not work correctly for a resistive load. |
| 22:34:25 | jacquesZzZz | GoRK: and I tried to build a kernel using that last night, but the kernel I built could not see the partition table on the flash |
| 22:34:37 | GoRK | i dont know... i have been sick for a few days and im already down 2 kernel versions! |
| 22:34:45 | jacquesZzZz | :-) |
| 22:35:25 | dirkx | bornet: but any radioshack or electronics or travel show in the Swiss can get you a similar one. You need a tiny one 35 watt should be enough. So that is CFH 25 or so. |
| 22:35:48 | bornet | dirkx: OK. I will look at this. |
| 22:36:57 | bornet | as i have an ISDN line, is it possible to use it (mazbe with a PCMCIA card) ? |
| 22:36:57 | andersee | GoRK: Russ provided me with a backtrace of the mount hang. I analyzed it vs the mtd source and spotted the problem and dwmw2 provided the fix. |
| 22:37:11 | andersee | GoRK: so its fixed now.... |
| 22:37:43 | jacquesZzZz | andersee: but how do I build a kernel with it fixed? |
| 22:38:17 | jacquesZzZz | andersee: my earlier attempt downloading latest mtd snapshot produced a kernel which thoiught there was no partition table on flash |
| 22:38:19 | dirkx | bornet: If your NT at home has an analog line - you can use it iwth that. You can also put a PCMCIA card in it for wireless or wired ethernet to the rest of your network at home. |
| 22:38:59 | Tangent | as_ : Read the section on moderate power for small heating appliances... http://www.iol.ie/~avondoyl/electrc2.htm |
| 22:39:16 | bornet | dirkx: my NT as 2 analog lines, but using the ISDN connection is always more fast |
| 22:39:19 | dirkx | bornet: but for example in italy the ISDN 'nt' - the white box near the door - does not normally have analog ports. You only get (two) if you pay a little more. But if you are using a normal (non ISDN) ophone in the house you ae fine. Some ISDN phones also have a 'data' or 'modem' port. |
| 22:39:29 | dirkx | bornet: ok - but in that case - you are limited to analog speed |
| 22:39:48 | dirkx | UNLESS you manage to find a 3.3v PCMCIA card with an ISDN modem. And get it to work with linux. |
| 22:40:10 | GoRK | andersee: ahh awesome! does buildroot-tux use the new or old kernel and/or does it include the fix for the mount bug in it? |
| 22:40:33 | jacquesZzZz | GoRK: old and no |
| 22:40:56 | as_ | Tangent, where on this page should I be looking? |
| 22:41:06 | as_ | There seems nothing here relavent. |
| 22:41:30 | Tangent | as_ : Nod.. nothing helpful.. just references to the fact that people make and sell that type of converter |
| 22:42:13 | as_ | Its it flawwed. |
| 22:42:44 | dirkx | bornet: - hmm a google.com search on 3.3v PCMCIA and modem and ISDN actually shows that that type of PCMCIA card is quite common. So if it works with linux you may be in luck :-) Swiss has euro-isdn ? |
| 22:43:05 | as_ | Tangent, this page could be referencing a different type of method. |
| 22:43:27 | bornet | dirkx: yes, this is now euro-isdn (altough we're not in the european union ;-) ) |
| 22:44:08 | bornet | dirkx: i think if the PCMCIA slot is working, i will found easly a ISDN adaptor. |
| 22:44:34 | as_ | It is possible to buy diodes with a forward voltage drop in excess of 100v. If this method were used, and I would still be dubios, it might work correctly on resistive heaters. |
| 22:45:18 | bornet | dirkx: how many time it take between the order and the delivery in Switzerlane (or Italy) |
| 22:45:23 | dirkx | Tangent: just a quick measure on the scope; load is a bay networks 9v adaptor. 220 volt AC (300 top top top on the scope) after the diode 107v AC and 149 top-to-top. The wave shape is kind of a sine with heavily chopped up tops; but not rectified so much. |
| 22:45:23 | as_ | However dirkx method as described, is flawwed. |
| 22:45:43 | dirkx | bornet: You'd have to ask BZFlag that (Tim Rikers) - and a lot depends on the speed/hurry you are in. |
| 22:45:57 | Tangent | isn't convinced that it's flawed for resistive loads |
| 22:46:14 | as_ | Tangent, I'm an EE, want me to go though the math again? |
| 22:46:50 | as_ | It is correct. |
| 22:46:52 | Tangent | as_ : Yep... I want to see a Spice simulation :) |
| 22:47:10 | dirkx | with a nice nutmeg graph at the end :-) |
| 22:47:13 | andersee | GoRK: The fix is to edit buildroot-tux/linux/drivers/mtd/mtdblock.c and remove the bogus call to invalidate_device() in mtdblock_release() |
| 22:47:14 | as_ | Power for a resistive load is V^2/R, happy with that? |
| 22:47:41 | andersee | that call causes a deadlock... |
| 22:48:29 | dirkx | have a ball, folks. We could settle this with a scope, a volt meter and a few beers, say in Sunny Italy ? - I am off for food now. Enjoy. |
| 22:48:41 | Tangent | as_ : Yep.. happy with that.. tho' it's Vrms |
| 22:49:00 | as_ | Yes, Vrms, or Just V for DC, the equations are the same. |
| 22:49:20 | as_ | So, if I double the voltage, the applience uses 4x the amount of power, right? |
| 22:50:13 | Tangent | as_ : Yep.. Happy with that |
| 22:50:55 | as_ | Right, now I insert a diode, we only get half of the waveform, so Vrms is only applies half the time, right? |
| 22:51:16 | as_ | ie, its on for half a cycle, and off for the other half. |
| 22:51:39 | as_ | So that reduces the power consumption, by a factor of 2. |
| 22:52:05 | as_ | Hense *4/2 = x2. The applience uses twice the power it was using before overall. |
| 22:52:31 | as_ | Happy now? |
| 22:52:54 | GoRK | andersee: cool. |
| 22:53:53 | bornet | just a question about software upgrade/configuration : as i understand by reading the wiki pages, the system come with inferno, and it seems difficult to put linux on it. |
| 22:54:06 | BZFlag | bornet: 4-7 days via priority mail etc. times are on the international postage calculator link |
| 22:54:23 | BZFlag | dirkx: and it's just Riker. ;-) |
| 22:54:47 | bornet | BZFlag: thanks. i must now wait on my PayPal account. :-(... |
| 22:55:19 | Tangent | as_ : But don't we halve the frequency at the same time? |
| 22:55:27 | Tangent | as_ : Thereby halving the power again |
| 22:55:31 | as_ | No, the frequency stays the same. |
| 22:55:43 | as_ | Even if you did half the frequency, the power would stay the same. |
| 22:55:44 | bornet | is it more difficult to put linux on the tuxscreen or on an iPAQ (what I have done many times) |
| 22:56:01 | BZFlag | bornet: I'll take a bank draft in USD if you want to mail one instead. |
| 22:56:14 | as_ | 100Hz has the same work function as 50Hz if its a sin wave. |
| 22:56:38 | BZFlag | bornet: about the same. The tux needs the FlashUnlock first. and then InfernoRemote. |
| 22:56:58 | BZFlag | bornet: but then updates are through the bootloader similar to the ipaq loader. |
| 22:57:05 | Tangent | as_ : Yes.. but how about a sine wave with no negative going portions? |
| 22:57:21 | Tangent | as_ : i.e. so instead of going +220 to -220, we go from 220 to 0 |
| 22:57:35 | as_ | Thats not how it works. |
| 22:57:53 | bornet | BZFlag: for the order, i think i will wait on the PayPal account... hope this will be at the end of the month. |
| 22:57:54 | Tangent | as_ : I've found two different companies that make and sell these things now |
| 22:57:55 | BZFlag | you don't halve the frequency, you just change the shape of the wave. |
| 22:58:05 | as_ | In order to understand the circuit, you need a common point, a ground. |
| 22:58:10 | BZFlag | bornet: either way is fine. thanx! |
| 22:58:29 | as_ | All the diode does is remove half tof the pulses. The negative half. |
| 22:58:54 | bornet | BZFlag: do you have try to use picogui on it ? |
| 22:59:31 | BZFlag | I have not yet. I do have microwindows on one. |
| 23:00:21 | bornet | i'm interesting in testing waba on it. Waba as a GTK and a PicoGUI port, so... |
| 23:03:25 | BZFlag | I have seen picogui screenshots running on the tux, I've just no done it myself. |
| 23:04:02 | GoRK | i run it :) |
| 23:04:10 | bornet | right. Micah is doing a great job with picogui. |
| 23:05:13 | GoRK | yeah, it's coming right along. it's nice working sort of untied from the standards of something like X :) |
| 23:07:51 | as_ | I'm going to bbl, dont you all kill yourselves playing with mains voltage. At least now while I'm not in a position to watch. |
| 23:22:23 | bornet | just surfing the web site. i don't understand at which speed the CPU runs. 133 or 206 MHz ? |
| 23:24:29 | Tangent | boris : 192MHZ at the moment |
| 23:24:48 | Tangent | boris : The CPU is rated at 133MHz... inferno overclocks it successfully to 206MHz in demo mode |
| 23:25:08 | Tangent | boris : But we haven't got all the memory timings correct for linux yet, so we can only manage 192MHz |
| 23:25:36 | bornet | Tangent: that's already great. |
| 23:26:12 | bornet | and what's about the memory ? is the 8+8MB base memory upgradable ? |
| 23:26:50 | Tangent | boris : It comes with 8MB on the mainboard, and an 8MB sodimm already fitted |
| 23:27:00 | Tangent | boris : You can replace the sodimm with a 32MB one |
| 23:27:49 | bornet | Tangent: thanks (bornet, boris is someone else ;) ) |
| 23:28:05 | Tangent | bornet : Pesky autocomplete |
| 23:28:16 | bornet | ;) |
| 23:31:15 | bornet | and what is the " 512k serial DataFlash" ? |
| 23:32:57 | GoRK | a 512kb serial atmel flash chip |
| 23:33:28 | GoRK | there is an mtd driver for it, but i dont think you can put a filesystem on it directly yet... you can read it and write it without problems, though |
| 23:34:11 | bornet | GoRK: this mean a slot for flash card ? |
| 23:34:22 | GoRK | no it's a chip |
| 23:34:45 | GoRK | compactflash or pcmcia flash (3.3v) should all work |
| 23:34:47 | as_ | Re. |
| 23:35:37 | bornet | GoRK: Oh ! I see. So, there is 4 MB flash + 512 kb (this not usable for a file system) ? |
| 23:37:51 | GoRK | yes |
| 23:37:59 | GoRK | it will be useable eventually for fs though, too |
| 23:38:21 | bornet | thanks |
