| 00:26.11 | file | hi prpplague |
| 00:30.19 | prpplague | is the tuxscreen wiki totally fux0red |
| 00:30.20 | prpplague | ? |
| 00:31.16 | file | prpplague: it always has been... and always will be... dead |
| 00:32.32 | GPSFan | file: not true, this time last year the wiki worked very well. |
| 00:32.41 | file | GPSFan: that was a joke |
| 00:32.51 | GPSFan | k, ;>) |
| 00:32.55 | file | prpplague: it's working fine for me - I can view pages... |
| 00:33.21 | file | or atleast a second ago I could |
| 00:33.36 | file | can't now |
| 00:33.38 | prpplague | ya i mean just not functioning well |
| 00:33.52 | prpplague | how hard is it to set up a wiki any way? |
| 00:34.01 | GPSFan | yea, so can I sometimes, other times they just hang my browser (IE 5.0) |
| 00:34.01 | file | it reminds me of something spawning processes and looping... |
| 00:34.02 | prpplague | i'd like to have one on my site |
| 00:34.08 | file | prpplague: not too hard |
| 00:34.12 | file | prpplague: even I could do it |
| 00:34.26 | prpplague | i wish i had someone to help with my site |
| 00:34.34 | prpplague | file: i'm html challenged |
| 00:34.49 | file | prpplague: mmm... phpnuke! |
| 00:36.45 | GPSFan | like now, I went to the recent changes page, cliked on a page, it loaded fine, I ckiked back, now the browser is hung with 100% cpu usage. this is the typical failure I see on the Tuxscreen wiki, it is said to be related to SF. |
| 00:37.01 | TheMasterMind1 | phpnuke?! |
| 00:37.06 | TheMasterMind1 | are you insane?! |
| 00:37.41 | file | TheMasterMind1: yes, yes I am |
| 00:38.00 | file | TheMasterMind1: then send me some SIMMs |
| 00:38.26 | TheMasterMind1 | heh |
| 00:38.27 | file | 32MB silver plated SIMms |
| 00:38.32 | file | er SIMMs |

| 01:05.14 | prpplague | anyone know which uart on the tux is the external rs-232 port connected to? |
| 01:07.19 | prpplague | nm found it |
| 02:29.03 | TomW | prpplague: pong |
| 02:49.28 | prpplague | TomW: i was looking at your tuxscreen dev board |
| 02:49.39 | prpplague | i don't see a max 232 chip on the main board |
| 02:49.59 | TomW | yeah, well don't look too hard at it, it probably has mistakes in it. |
| 02:53.13 | prpplague | ahh ok |
| 02:53.25 | TomW | heh, guess the most obvious thing I didn't put on the schematic, eh? |
| 02:53.29 | prpplague | TomW: been working on my board this evening |
| 02:54.16 | TomW | I am doing paperwork tonite. :( |
| 02:54.26 | prpplague | fun |
| 02:58.33 | TomW | trying to make sense of this paperwork. Decided that instead of having heaps of envelopes tied with elastic bands for the bank statements, utility bills, etc., that I should just pull them out, staple them together, and file them into manilla folders in the filing cabinet. |
| 02:58.58 | prpplague | TomW: eww |
| 02:59.08 | TomW | prpplague: imagine that, I found a use for the "extra" space in the filing cabinet. :/ |
| 02:59.13 | prpplague | TomW: lol |
| 03:00.00 | TomW | What is going to shock the shit out of my accountant is when I hand him the books over for 2002 _before_ October 15th for him to do the Taxes. |
| 03:00.22 | prpplague | TomW: hey on j600 601 did you actualy ground every one of the pins that were listed to ground? |
| 03:00.36 | TomW | Maybe I shouldn't do that, I haven't filed before Oct 15th in 7 years, maybe the IRS will flag me if I file this year in April? |
| 03:00.46 | prpplague | lol |
| 03:00.53 | prpplague | TomW: red flag city |
| 03:01.15 | TomW | prpplague: yup, they were grounded all together. |
| 03:01.25 | prpplague | TomW: ok just checking |
| 03:01.34 | TomW | prpplague: I just "wandered" some bus wire between the pins. |
| 03:02.33 | prpplague | TomW: ya i'm re-doing my frankin-tux |
| 03:03.13 | TomW | prpplague: well, I am out of manilla envelopes, so, I guess the rest of this crap will have to be filed later. |
| 03:03.25 | TomW | s/envelopes/folders/ |
| 03:03.32 | prpplague | TomW: file it in the paper schreder |
| 03:03.52 | prpplague | TomW: do the worldcom/enron dance |
| 03:03.56 | TomW | no! The guys at the IRS might want to see some of this stuff! |
| 03:04.18 | TomW | I can afford the accountant, but not a Tax Attourney |
| 03:04.33 | prpplague | lol |
| 03:04.54 | TomW | I don't make enough money to be able to cheat the IRS. |
| 03:05.10 | prpplague | lol, me either |
| 03:07.23 | prpplague | thats the best think about working for someone else, i can go to h&r block to get my taxes done |

| 03:09.05 | TomW | prpplague: I have the schematic for the CLPS-7500FE EVB and I just dragged it out (that is why I had to do paperwork, so I had room for the binder). |
| 03:09.26 | prpplague | sorphin: IMHO, thats like saying you can fsck yourself |
| 03:09.30 | TomW | prpplague: looks like the a lot of the webpal was lifted directly out of the EVB design. |
| 03:09.42 | sorphin | prpplague: umm... why's that? |
| 03:09.43 | prpplague | TomW: surprise |
| 03:10.03 | TomW | same 37C665 I/O combo chip, etc. |
| 03:10.18 | sorphin | prpplague: i've figured my taxes, and i've had them done, exact same result.. the only diff is that i wasted the $ paying someone :P |
| 03:11.24 | prpplague | sorphin: ya well, i can work on code for 48 hours straight if i have to, 10 minutes of the 1040ez and i'm ready to go postal on the idiots that designed the tax system |
| 03:11.36 | cpenguin_home | hey people again |
| 03:11.41 | sorphin | prpplague: i've never had that problem |
| 03:11.43 | TomW | prpplague: Cirrus used a CH7003 video generator and WebPal used the CH7001. |
| 03:11.49 | sorphin | prpplague: 1st off, i can't file 1040ez :P |
| 03:11.54 | sorphin | cpenguin_home: re |
| 03:12.01 | TomW | cpenguin_home: ? You were expecting Vampires? |
| 03:12.02 | prpplague | cpenguin_home: lo |
| 03:12.24 | prpplague | TomW: how hard does it look to attach lcd to the 7500FE? |
| 03:12.25 | sorphin | prpplague: and 2nd, my taxes are easy to do, the deductions i have, aren't even enough to override the standard deduction |
| 03:12.47 | prpplague | sorphin: even with that, i get frustrated with the questions |
| 03:13.18 | sorphin | 'like what? |
| 03:13.21 | sorphin | 'Name ? :P |
| 03:13.31 | prpplague | sorphin: 1040ez-plague - pay_tax=( _how_you_made_this_year_ * .1 ); |
| 03:13.46 | sorphin | umm |
| 03:14.05 | prpplague | sorphin: thats my idea of taxes |
| 03:14.12 | sorphin | maybe because i'm single it's easier, i dunno |
| 03:14.19 | prpplague | sorphin: no |
| 03:14.20 | sorphin | i can do my taxes in a couple mins |
| 03:14.34 | prpplague | sorphin: i don't keep those forms around, they just make me mad |
| 03:14.45 | sorphin | heh |
| 03:14.57 | sorphin | 'the only times i've had to have someone do them |
| 03:15.04 | sorphin | 'is split residency |
| 03:15.55 | sorphin | i don't get much back on my taxes so i'm not too worried about it |
| 03:16.08 | TomW | prpplague: basically, all the LCD signal pins attach directly to pins on the CPU, with the exception of a clock line that comes off the system clock generator (external clock source). |
| 03:16.11 | sorphin | i'd rather have the $ now |
| 03:16.32 | sorphin | TomW: basically why it can't do higher res atm ? |

| 03:18.16 | TomW | prpplague: both boards use the Chrontel CH9294 clock generator to drive the video clocks. |
| 03:19.24 | TomW | prpplague: I wonder if the 2 Meg Flash SIMMs for the Cirrus EVB would work in the WebPal? |
| 03:20.38 | sorphin | heh |

| 03:20.44 | prpplague | TomW: sounds like a knock off |

| 03:21.03 | prpplague | TomW: of course i'm using the assabet board for the hackkit |
| 03:21.27 | TomW | prpplague: No IDE connector on the Cirrus board, but it does have two ISA slots. |
| 03:21.54 | prpplague | TomW: that means the irq's are directly to the isa? |
| 03:22.10 | TomW | must be... |
| 03:24.52 | TomW | prpplague: ISA IRQ lines go into a PAL (16V8), then are pollable via an Octal Buffer (suppose they get an INT, then look to see what line is "set"). |
| 03:25.36 | TomW | prpplague: IRQs are probably combined within the PAL and initiate a single INT request to the CPU. |
| 03:34.09 | TomW | prpplague: no connections on the WebPal for the LCD controller signal lines. |
| 03:34.27 | prpplague | TomW: darn |
| 03:34.27 | TomW | prpplague: WYSIWYG |
| 03:35.17 | TomW | prpplague: 'tis ok for me though, I have decided to layout a board for the 7500FE chips that I have here, I can add that missing connector. |
| 03:35.53 | prpplague | TomW: fun |
| 03:36.15 | TomW | prpplague: probably stick 16/32Meg of DRAM + 32K boot prom + a CF socket on the board. |
| 03:36.15 | prpplague | TomW: got any estimates on totaly price on your board yet? |
| 03:36.46 | TomW | prpplague: naw, still tinkering with the signal lines stuff, what gets hooked to what. |
| 03:37.21 | prpplague | TomW: are you gonna have control of sales of the board? |
| 03:38.39 | TomW | yes and no, I will sell the design to the customer, but that would be a dedicated system for them to use in their application. I would keep a more specialized form of the design for me. Like adding / deleting hardware. |
| 03:38.59 | TomW | s/the design/a design/ |
| 03:39.12 | TomW | s/the design/a design/g |
| 03:39.17 | TomW | :D |
| 03:40.38 | TomW | prpplague: hmmm, I could save myself some trouble, perhaps, and cost, by robbing parts off a webpal to use on my protos. Like the CH9294 clock generator. |
| 03:40.51 | TomW | prpplague: ... and maybe some xtals. |
| 03:41.56 | prpplague | TomW: i was just thinking, if you get something produced you could sell it on my small-linux.com along with the hack kit |
| 03:42.38 | TomW | prpplague: not much else applies to what I need. The 7500FE board will have an LCD interface on it, plus some General Purpose I/O lines, and a total of 6 serial ports (2 RS232 and 4 that are switchable between RS485 or RS232). |
| 03:43.31 | TomW | prpplague: bring some signals out to a header / edge connector for ISA compatability / expansion. |

| 05:42.15 | Russ | unless you connect the other address line |
| 06:24.51 | TomW | Russ: yeah, I looked at that. It is not the task of soldering a wire to the un-connected pin as it is routing the wire to the bottom of the board. The PCB is solid without any drilled holes in the interior. I suppose I could attempt a "best guess" and drill a hole, hoping I don't break internal layer connections... |

| 17:08.01 | sorphin | GPSFan: no wonder they need such a big regulator :P |
| 17:08.19 | GPSFan | sorphin: that sort of interesting info should "pop" out of the schematic that TomW is doing. |
| 17:08.41 | sorphin | GPSFan: you saw tom's comment about how it's mostly pulled from the reference board ? |
| 17:08.51 | GPSFan | sorphin: yeah, it runs a lot cooler without the crontel powered. |
| 17:09.48 | GPSFan | sorphin: I had come to the same conclusion as tom did after looking at the Cirrus doc's, just haden't got the energy to reverse engineer the schematic. |
| 17:10.12 | sorphin | hmm |
| 17:10.24 | sorphin | <PROTECTED> |
| 17:10.24 | sorphin | Had to cut JP1 Had to cut JP1 (modified 0 times) newell |
| 17:10.24 | sorphin | Profile |
| 17:10.25 | sorphin | One of my webpals didn't want to run reliably in gdb or comm with wpflash. Cut the trace bridging JP1 and everything is fine. Suspect that the micro's port pin is not tristated, so it's conflicting with the console serial port input (J11-3). |

| 17:13.44 | sorphin | prpplague: and assuming she doesn't think they're a new accessory or something |
| 17:14.05 | sorphin | prpplague: i still feel bad for ashley |
| 17:14.18 | prpplague | sorphin: getting married? oh ya |
| 17:14.30 | prpplague | sorphin: she's a sweety |
| 17:14.48 | sorphin | prpplague: well, marrying a complete loser |
| 17:15.10 | sorphin | odd |
| 17:15.14 | *** join/#elinux TomW (tom@147seg-pc-1624-14.msns.str.ptd.net) |
| 17:15.20 | sorphin | if i copy stuff from usb drive to usb drive |
| 17:15.21 | prpplague | TomW: lo |
| 17:15.29 | sorphin | the usb crap hangs and i have no choice but to reboot |
| 17:15.33 | TomW | prpplague: max RAM on the WebPal is 32M. |
| 17:15.37 | sorphin | but i can access both invidivually |
| 17:15.40 | sorphin | TomW: righto |
| 17:15.50 | sorphin | TomW: look on linux-hacker |
| 17:15.58 | sorphin | TomW: a post about the powerdown pin on the crontel |
| 17:15.59 | TomW | prpplague: you have to use 2K refresh _only_, no 4K refresh devices. |
| 17:16.14 | sorphin | TomW: what about w/ the mod ? |
| 17:16.22 | prpplague | TomW: hey, quick question, on the tuxscreen schematic there are two buffers on the incomming lines of the rs-232, are those really nessary with a max3232 ? |
| 17:16.23 | TomW | sorphin: mod? |
| 17:16.32 | prpplague | TomW: right i have 2k refresh |
| 17:16.38 | prpplague | TomW: adding the a12 line |
| 17:16.43 | sorphin | TomW: yeah, the one i pinned out here too :P the 101 -> pin on the ram socket |
| 17:16.56 | TomW | you mean the RA11 line. |
| 17:17.08 | sorphin | well, he calls it A12 |
| 17:17.10 | sorphin | ubt yes that |
| 17:18.03 | TomW | sorphin: sure, if you can figure out how to get the wire from the top of the PCB down to the bottom to where you can solder it to the pin. Then you could have 64Meg. |
| 17:18.13 | sorphin | TomW: ummm |
| 17:18.17 | sorphin | tomw :someone else did it |
| 17:18.25 | sorphin | you drill a hole in the open area :P |
| 17:18.29 | TomW | there is no place to pass a wire from the topside of the board to the bottom. |
| 17:18.35 | sorphin | yes there is :P |
| 17:18.44 | prpplague | TomW: some models of the board have a hole |
| 17:18.50 | sorphin | prpplague: ;) |
| 17:18.58 | prpplague | TomW: only 3 of the ones i have, have holes |
| 17:19.05 | sorphin | prpplague: drill bit? what drill bit? ;) |
| 17:19.09 | TomW | sorphin: uhhuh, let me know where you found an "open spot" on a multilayer PCB, ok? |
| 17:19.21 | prpplague | TomW: lol |
| 17:19.29 | sorphin | TomW: ask the guy who did the mod :P |
| 17:19.35 | prpplague | TomW: i was planning to look more detailed about the mod tonight |
| 17:19.45 | sorphin | there's a page showing it |
| 17:20.47 | TomW | You could actually increase the RAM to 128M by adding the RA11 + RAS1 + RAS3 lines (three wires) and use a 4K refresh device. |
| 17:21.27 | TomW | problem is not soldering the wires to the CPU (you need steady hands + microscope), but passing the wire to the bottom of the PCB. |
| 17:21.39 | sorphin | TomW: ummm |
| 17:21.50 | sorphin | TomW: this guy that did the mod drilled w/ no probs :P |
| 17:21.53 | sorphin | and shows where |
| 17:22.00 | sorphin | if i could find the damn url (ken showed me it) |
| 17:22.07 | sorphin | but phoenix seems to not be keeping bookmarks |
| 17:22.08 | TomW | prpplague: " two buffers on the incomming lines"? |
| 17:22.48 | prpplague | TomW: ya let me grab the schematic |
| 17:23.17 | TomW | sorphin: agreed, it would be possible to "find" an area of the board that you could drill, I thought of that too, it still could be done. You could drill over next to the LM323 heatsink area of the PCB. |
| 17:23.27 | sorphin | actually |
| 17:23.42 | prpplague | TomW: doesn't the length affect timing? |
| 17:23.43 | sorphin | he did on the area between the cpu and the simm slots |
| 17:23.50 | sorphin | that open area to the left |
| 17:24.36 | prpplague | TomW: 74LVC125 |
| 17:24.57 | TomW | prpplague: yes, but you can adjust the DRAM timing within the ARM, I haven't looked at it on the 7500FE, but the SA1100 used a bit string to wiggle the RAS + CAS lines. |
| 17:25.16 | prpplague | TomW: ahh |
| 17:26.38 | prpplague | TomW: ya i'm showing two 74LVC125's before the max202e chip |
| 17:29.50 | TomW | prpplague: they are using the 74LVC125's as voltage level shifters. The output of the MAX202 is 0..+5v, the SA1100 processor is a 3.3v processor, it's input signal levels are spec'ed at 0..+3.3v, the 74LVC125 does that voltage conversion for you. |
| 17:30.44 | TomW | prpplague: you may damage the SA1100 by driving one of it's input pins at TTL levels. |
| 17:31.19 | prpplague | TomW: ahh, ok i see, the the max202 is a 5v tolerant chip, i'm using the max3232 which is 3.3v tolerant so i don't need the 74LVC125's |
| 17:31.44 | TomW | prpplague: _not_ 5volt tolerant, it _is_ a TTL device. |
| 17:32.43 | TomW | prpplague: the term "tolerant" means that it will operate outside of the normal VDD supply range (3.3v) and accept (tolerate) a higher voltage at it's pins. |
| 17:33.09 | TomW | prpplague: the MAX3232 is a 3.3v device. |
| 17:33.16 | TomW | prpplague: ok? |
| 17:33.41 | prpplague | TomW: gotcha, my bad on terminology, meaning one thing, typing another |
| 17:34.04 | TomW | prpplague: it is always a matter of props & levels (propagation times + voltage levels for HIGH & LOW states). |
| 17:34.22 | sorphin | TomW: digging through ibots logs for that url |
| 17:34.31 | prpplague | TomW: so the max202 is a TTL device, i.e it operates on a 0 to +5v levels |
| 17:35.07 | prpplague | TomW: so what do you call something that is a 3.3v device? |
| 17:35.26 | TomW | prpplague: the switching times (rise / fall times) are sometimes critical as well, they add to the inherent time that it would take a signal to be "passed" from the input of a device to the output. |
| 17:35.45 | TomW | prpplague: a 3.3v device. :) |
| 17:35.50 | prpplague | TomW: lol |
| 17:35.54 | TomW | heh |
| 17:36.16 | prpplague | TomW: the delay being refered to as the "propogation time" ? |
| 17:37.34 | prpplague | TomW: so, are the 74LVC125's an acceptable device to keep around for conversion of 3.3v levels to TTL? |
| 17:38.00 | TomW | prpplague: prop delays are the amount of time it takes for a signal to "pass" through (or activate) a device from the input to cause an output to change state. |
| 17:38.51 | TomW | prpplague: one of them, the LVC family is inherently a 3volt device family specifically designed for 5volt tolerant operation. |
| 17:39.33 | prpplague | TomW: ok thanks for the info |
| 17:39.35 | TomW | prpplague: rise time on an output is also sometimes referred to the "slew rate" of output. |
| 17:39.40 | sorphin | TomW: it's here http://www.luban.org/Webpal/ |
| 17:39.49 | sorphin | he did the mod, drilled, etc.. |
| 17:39.58 | prpplague | TomW: ahh i've seen that in the maxim docs |
| 17:40.01 | sorphin | that's where i confirmed i was right about which pins to use |
| 17:40.30 | prpplague | TomW: you know i was serious about setting up an account with you |
| 17:40.53 | prpplague | TomW: it'd be well worth the money to pester you with some question now and then :) |
| 17:41.24 | TomW | prpplague: your rise, or slew, can be calculated if you know that Timing constant of the circuit. For example, your output (driving device) has a specific output resistance, usually expressed as "output drive current" and the input of the succeeding stage has an input capacitance. |
| 17:41.52 | TomW | prpplague: most logic has a 4K output resistance. |
| 17:41.55 | TomW | ok? |
| 17:42.59 | TomW | prpplague: you effectively have a series circuit of a resistor and a cap, when you apply voltage to the circuit (or ground it to 0v), you have a specific time that it will take to "charge" the capacitor. |
| 17:43.25 | prpplague | TomW: basically your calculating a resistor/cap charge/discharge time |
| 17:43.32 | TomW | prpplague: correct! |
| 17:44.02 | prpplague | TomW: ahh, much clearer |
| 17:44.42 | TomW | prpplague: now keep in mind that that circuit is actually a more complex one: a resistor (source current supply) a cap (the input of the succeeding stage) and an inductor (wire trace between the input & output). |
| 17:45.36 | TomW | prpplague: even though you are "digital" a lot of AC theory applies as your signals are switching at high speeds (frequency). |
| 17:45.57 | prpplague | gotcha |
| 17:46.25 | TomW | prpplague: so, you not only have impedance (resistance + capacitance), but you have reactance (the AC equivilant). |
| 17:46.35 | sorphin | TomW: specifically, here's the pic w/ the hole if you don't wanna look at the page :P |
| 17:46.37 | sorphin | http://www.luban.org/Webpal/Hole_And_CPU.jpg |
| 17:48.05 | prpplague | TomW: ok so even small traces can have a inductive resistance to the change in state |
| 17:48.07 | TomW | sorphin: thanks! that is helpfull, I have it bookmarked. |
| 17:48.37 | TomW | prpplague: actually the thinner the trace, the higher the series resistance of that trace. |
| 17:49.20 | TomW | prpplague: Now, think on this: do you know what a wave guide (RF transmission line) is? |
| 17:50.03 | prpplague | TomW: yes i think i know it more of the military name, but go ahead |
| 17:52.29 | CosmicPenguin | prpplague: how long were you in the army? |
| 17:52.40 | TomW | prpplague: well, a trace on a circuit board actually _is_ / _becomes_ an RF wave guide and exhibits an inherent impedance. The signals switching through that wire are fast, you can estimate the frequency of operation by looking at (or calculating) the rise / fall times of the signal itself (remember that a sine wave has a periodic rate at which it runs, thus a digital signal also has a periodic rate, hence a frequency of operation). |
| 17:53.04 | prpplague | CosmicPenguin: 4 years, airbourne |
| 17:53.22 | TomW | prpplague: a peice of coaxial cable is a wave guide / transmission line. |
| 17:53.23 | CosmicPenguin | prpplague: one of our HW partners used to be a frogman |
| 17:53.41 | CosmicPenguin | It seems like a wierd jump from demolitions guy to hardware designer, but heck, I'll go with it... :) |
| 17:54.04 | TomW | prpplague: you ever own a CB / Ham radio? |
| 17:55.01 | prpplague | TomW: lol, no, but worked on lots of military including singars |
| 17:55.24 | TomW | prpplague: do you know about SWR (Standing Wave Ratio)? |
| 17:55.53 | TomW | prpplague: how about the "Maximum Power Transfer Thereom"? |
| 17:56.17 | TomW | one of Kirchoff's Laws of electricity. |
| 17:56.19 | prpplague | TomW: right the ratio at which the reflected wave produces a standing wave |
| 17:56.26 | TomW | correct! |
| 17:56.45 | prpplague | TomW: right i know _about_ that stuff, just never gotten any hands on to understand it |
| 17:56.54 | TomW | "maximum power transfer occurs when the source impedance is equal to the load impedance" |
| 17:57.04 | prpplague | TomW: i'm missing the practical end of things |
| 17:57.36 | TomW | So, what do you think happens when a 4K source (digital output) is driving a 40K load (input of a gate)? |
| 17:58.17 | TomW | <PROTECTED> |
| 17:58.23 | prpplague | TomW: you gonna get a power "reflections" |
| 17:58.51 | prpplague | TomW: and depending on the connections between the device get some rf noise out? |
| 17:58.55 | TomW | prpplague: _that_ is why you see RS485 circuits placing a 300 ohm resistor across the inputs to the receiver. |
| 17:59.05 | sorphin | TomW: just send him a damn EE fundamentals book ;) |
| 17:59.39 | prpplague | sorphin: i've already read several, i don't learn well that way |
| 17:59.39 | TomW | prpplague: also, that is how "active bus termination" works, you are minimizing the impedance mismatch, thus reducing the "reflection" and resulting distortion. |
| 17:59.40 | sorphin | TomW: re traces vs rf |
| 17:59.44 | prpplague | sorphin: i like lectures/interaction |
| 18:00.00 | prpplague | TomW: i.e. scsi and esdi bus's |
| 18:00.04 | sorphin | TomW: it only becomes a major factor when you really get into higher frequencies and it causes stray capacitance |
| 18:00.19 | TomW | sorphin: a digital circuit is more RF like, your correct. |
| 18:01.13 | sorphin | TomW: it's why i stay away from designing high speed circuits ;) |
| 18:01.27 | TomW | sorphin: ahh! Look at the rise times of the signals you are switching on the digital lines, they are running at several hundred megahertz! Even on a lowly 8051 you can have switching times reaching up into 100MHz. |
| 18:01.33 | sorphin | TomW: figuring that crap out to avoid interference gets on my damn nerves |
| 18:01.47 | sorphin | TomW: i'm thikning starting at 1ghz |
| 18:02.20 | sorphin | TomW: i have a microwave motion detector that the talk about that in the book for it, they run the traces a certain way, because the damn thing operates at 2ghz |
| 18:02.34 | TomW | sorphin: no, you don't have to figure it out, just respect it and accept that it is there. Design your boards to avoid those problems, develop an appreciation for the AC effects. |
| 18:02.49 | sorphin | TomW: that's what i mean, figure how to avoid it |
| 18:03.15 | TomW | I look at a circuit board as being like a living thing, it "breathes". |
| 18:03.30 | prpplague | TomW: and farts |
| 18:03.36 | TomW | LOL! |
| 18:03.42 | TomW | good one! |
| 18:03.45 | sorphin | prpplague: not a beer one hopefully |
| 18:03.54 | TomW | SBD |
| 18:04.08 | TomW | it also can get the "hiccups". |
| 18:04.17 | TomW | :D |
| 18:04.39 | prpplague | TomW: ya well my z80 ms.pacman board is being just plain bitchy |
| 18:04.56 | prpplague | TomW: the ps transformer when out and smoke some of the chips |
| 18:05.09 | sorphin | prpplague: um.. that'd be because it's a bitch (it's MS pacman after all) |
| 18:05.17 | TomW | prpplague: too bad you cannot put the smoke back in... |
| 18:05.24 | prpplague | TomW: no pcb damage so i'm hoping that replacing the stuff will be ok |
| 18:05.54 | prpplague | TomW: lots of 74LS161's and 74LS174's |
| 18:06.03 | sorphin | TomW: you think it would be worth doing anymore than the a12 line ? |
| 18:06.34 | prpplague | TomW: thanks for the info, gotta run, bbl |
| 18:06.46 | sorphin | CosmicPenguin: flamewar? where ? |
| 18:06.56 | TomW | the RA11 mod would be a worthy mod to do, 64 meg with only one wire is pretty inviting mod to do... |
| 18:07.20 | sorphin | TomW: and 4k refresh at that |
| 18:07.21 | TomW | where? where? I wanna go see too! |
| 18:08.19 | sorphin | TomW: i dunno if that guy knows how to count tho |
| 18:08.23 | sorphin | 20 pins up isn't 101 |
| 18:08.46 | sorphin | least not from how i learned to count |
| 18:09.05 | TomW | RA11 needs to be attached to pin 29 of the RAM SIMM socket. |
| 18:09.11 | sorphin | i know |
| 18:09.14 | TomW | k |
| 18:09.20 | sorphin | i meant on the cpu |
| 18:09.24 | TomW | heh |
| 18:09.41 | sorphin | "Now, put the wire thru hole and cut it so it will reach about the middle of CPU chip. Clean the wire tip and solder it to pin 101 of the CPU. That'll be 20th pin if counted up from lower left CPU corner on the photo above" |
| 18:10.02 | TomW | interesting bit of manual dexterity testing in getting that wire soldered to the cpu pin, eh? |
| 18:10.18 | sorphin | not really, 30g wire will work great |
| 18:10.24 | TomW | yes |
| 18:10.26 | sorphin | i just gotta find mine, else hit RS |
| 18:10.58 | sorphin | TomW: soldering a wire to the chip will be cake for me.. now... if i had to solder down the damn chip... |
| 18:11.01 | sorphin | that's anotehr story |
| 18:11.09 | TomW | I'm more interested in reverse engineering the electronics to the point of building my own 7500FE based PCB. |
| 18:11.47 | sorphin | towm: well, you said it was quite a bit pulled from the reference design, no ? |
| 18:12.44 | TomW | sorphin: right. What I am mainly concerned with is looking at the Clock & POR & RESET circuits to see how they did them on the WebPal compared against the EVB. |
| 18:12.55 | sorphin | ah |
| 18:13.35 | TomW | the reset (POR) logic of the 7500FE reads like crap in the manual, apparently there is a number of ways to "reset" the chip. |
| 18:13.49 | sorphin | one mod i'm definately doing via HW or SW, however, is powering down the crontel.. that shit does get hot |
| 18:13.56 | sorphin | heh |
| 18:13.56 | sorphin | yeah |
| 18:14.15 | sorphin | TomW: like toggle the power :P |
| 18:14.44 | TomW | hadn't noticed, but then, I have not looked at a running board. I have been staring at one I pulled to buzz out. |
| 18:15.08 | sorphin | nod |
| 18:15.22 | sorphin | not that the arm stays very cool that i recall, but still |
| 18:15.45 | sorphin | w/o the crontel, you could prolly get away w/ a much smaller regulator, cuz the arm shouldn't pull that much |
| 18:15.54 | sorphin | nothing near what the reg can deliver |
| 18:18.00 | TomW | sorphin: that regulator is a joke! Who uses a series regulator now days to supply an AMP or more of current anyway. Didn't they know about switching regulators? |

| 18:19.23 | TomW | the WP was probably designed by a "digital" engineer with no experience with switchers, he took the easy way out. |
| 18:19.48 | TomW | but, easy to be critical of someone else's design, isn't it? |
| 18:20.02 | sorphin | towm: apparently not, tho the webpal is from 1997 atleast ;) |
| 18:20.59 | TomW | yeah, you're right, the switchers of that "era" were only running at 85% efficency, not enough to justify their use. :P |
| 18:21.42 | TomW | sorphin: I just type "so" then hit tab in xchat. |
| 18:21.59 | sorphin | i'm using BX from 30 miles away from where the session is :P |

| 18:23.04 | TomW | B&W works for me. |

| 18:26.10 | TomW | anyway, I have to deliver that new Linux workstation to the customer today. It took me 14 hours to figure out how to pull NT off the IDE drive and get it working, again, in VMware. _this time_ I backed it up on tape! |
| 18:26.22 | sorphin | heh |
| 18:26.27 | sorphin | it's a pita |
| 18:26.32 | sorphin | same w/ 2k |
| 18:26.35 | sorphin | the hw changes |
| 18:26.38 | sorphin | and it wigs out |
| 18:27.00 | TomW | he's not going to like this, I won't give him the root password on this system. He is getting dangerous, he does a lot of "brute force" shit when he is root. |
| 18:27.10 | sorphin | heh |
| 18:28.48 | TomW | he trashed the other vmware installation of NT because he was trying to install sound drivers into the NT. It blue screened on him at boot, and it was hammered! The damned NT was in an NTFS partition and you cannot fix that thing when it is in NTFS! Micro$oft really fscked up on that one! |
| 18:29.33 | sorphin | yup |
| 18:29.36 | sorphin | i know |
| 18:29.53 | TomW | I could mount the drive under another VMware machine, but I couldn't get at the registry to fix it. |
| 18:30.10 | sorphin | of course, i have to fscking xfer from that drive to giga's maine drive then to another ext2 drive |
| 18:30.32 | sorphin | why? because fat32 decides lower and upper case are == |
| 18:30.39 | TomW | heh |
| 18:30.55 | sorphin | so it ignores the difference, and mkisofs DOESN'T make video_ts.ifo 1st in the image |
| 18:31.01 | sorphin | because it's not alphabetically |
| 18:31.16 | sorphin | fsking thing is looking for UPPERCASE which it can't be on fat32 |
| 18:31.21 | sorphin | stupid windows crap |
| 18:31.36 | TomW | that fscks up even PDF's that they generate on Windoze platforms. I had that problem, some clueless fool generated a PDF on windoze then I had to make it work on linux. |
| 18:32.32 | TomW | sorphin: had to look into the PDFs themselves to see what capitalization to change the filenames to . |
| 18:33.09 | sorphin | hehe |
| 18:33.39 | TomW | He does have the Adobe PDF creation tools, I understand that you can use those to edit PDFs directly. But, I am so used to ps2pdf that it just goes against my grain to have to learn another freakin' tool. |
| 18:33.50 | sorphin | hehe |
| 18:34.05 | sorphin | cuz ps2pdf was a pain |
| 18:34.11 | sorphin | and PStill for linux wouldn't run |
| 18:34.18 | sorphin | cuz it is linked to shite libs |
| 18:35.31 | TomW | This customer is a software whore, if it glitters, he buys it and loads it into his NT box! :( You cannot do that to NT, it chokes when you load too much shit into it. |
| 18:36.07 | sorphin | nt isn't meant for anything fancy |
| 18:37.10 | TomW | Ah well, I shouldn't bitch too much, his actions do give me reason to charge to keep his stuff running and it pays the rent. Funny how that works, windoze is a peice of crap O/S, but it is such an income generator. It is the O/S that you just love to hate |
| 18:37.27 | sorphin | yup |
| 18:37.42 | sorphin | now if maxim will just get me my samples |
| 18:37.43 | sorphin | ;) |
| 18:37.51 | TomW | what are those? |
| 18:37.57 | CosmicPenguin | Wow, this has been one noisy room today |
| 18:38.05 | sorphin | TomW: 233's and 235s |
| 18:38.08 | CosmicPenguin | I look away for 2 seconds, and bam... I'm lost |
| 18:38.15 | sorphin | CosmicPenguin: we're doing it just to lose you ;) |
| 18:39.25 | TomW | CosmicPenguin: you have to be either "on the bus or off the bus" buddy. |
| 18:39.39 | CosmicPenguin | sorphin: you' won't lose me that easily, this room is the only social interact I seem to be getting lately |
| 18:39.51 | sorphin | CosmicPenguin: sounds like a personal problem ;) |
| 18:41.04 | TomW | CosmicPenguin: hehee |
| 18:41.33 | sorphin | TomW: gonna use the 233s for now, and maybe later on if i decide to do both ports, i'll just use the 235s |
| 18:41.53 | TomW | sorphin: digikey has that stuff. |
| 18:42.00 | sorphin | yeah |
| 18:42.05 | sorphin | but that costs $ ;) |
| 18:42.11 | TomW | but, then, you don't want to pay. |
| 18:42.13 | sorphin | these were free :P |
| 18:42.17 | TomW | sheesh, leech! |
| 18:42.21 | sorphin | hey |
| 18:42.29 | sorphin | maxim sends me crap every month |
| 18:42.30 | TomW | heh |
| 18:42.33 | sorphin | telling me i can get samples |
| 18:42.38 | sorphin | and sending me data sheets and crap |
| 18:42.42 | TomW | yeah |
| 18:42.50 | sorphin | so if they're gonna offer |
| 18:42.51 | ade|desk | yeah i love em |
| 18:42.53 | sorphin | i'm gonna use :P |
| 18:42.59 | TomW | you have to take 'em up on it so they continue to offer it to you. |
| 18:43.29 | TomW | I don't know how they make money with all the samples they seem to give away. |
| 18:43.29 | ade|desk | years ago they sent me a shit load of 16bit dac/adc :) |
| 18:43.45 | sorphin | TomW: all i could think of to get was hte 233/235s |
| 18:43.52 | sorphin | i dunno what they make now that i could use |
| 18:43.59 | sorphin | don't need any dallas time clocks ;p |
| 18:44.08 | TomW | samples are like getting presents under tree when you were a kid... |
| 18:44.10 | TomW | :) |
| 18:44.27 | sorphin | heh, atmel sent me 6 flash samples before |
| 18:44.36 | sorphin | sst was more of a pain |
| 18:44.40 | sorphin | hence why i went w/ atmel |
| 18:44.49 | sorphin | too bad atmel is annoying w/ specs sheets |
| 18:44.49 | TomW | sorphin: yeah, but most processors don't have any notion of what time / date it really is. |
| 18:45.21 | sorphin | TomW: yet i still see boards w/ dallas chips |
| 18:45.51 | TomW | sorphin: the stuff I design is autonomous and is not connected to an ntp server. It has to know the correct date / time when it powers up. |
| 18:46.14 | sorphin | nod |
| 18:46.45 | TomW | besides, you cannot have all the files dated "jan 1,1970" can you? :D |
| 18:47.11 | Russ|werk | mine aren't |
| 18:47.13 | Russ|werk | I'm in AZ |
| 18:47.20 | Russ|werk | so they are date dec 31, 1969 |
| 18:47.29 | TomW | ROTFL |
| 18:47.50 | sorphin | Russ: i knew AZ was fscked, but i didn't know it was that bad ;) |
| 18:48.10 | TomW | they are in their own little world out there. |
| 18:48.22 | Russ|werk | -0700 |
| 18:48.24 | sorphin | TomW: just as long as they stay there ;) |
| 18:48.31 | TomW | oooo |
| 18:48.43 | TomW | brutal |
| 18:48.56 | Russ|werk | so, epoch came to AZ on dec 31, 1969 17:00 |
| 18:49.33 | TomW | yeah, that may be true as the computers didn't have to use ZULU time back then. |
| 18:49.45 | TomW | s/ZULU/GMT/ |
| 18:49.47 | sorphin | well, i'm in -0600 :P |
| 18:49.58 | sorphin | and mine all say Jan 1, 1970 :P |
| 18:50.24 | Russ|werk | TomW: what I mean is on a system with no clock, but has the TZ set in the environment, ls shows the file dates as dec 31, 1969 |
| 18:50.41 | Russ|werk | unless you are east of GMT, then it has jan 1, 1970 |
| 18:50.43 | TomW | I think that Russ deliberately inits the linux clock in his controllers to -1. |
| 18:51.07 | Russ|werk | TomW: could go all the way to -0x80000000 |
| 18:51.26 | Russ|werk | ~1902 |
| 18:51.56 | sorphin | can't wait till 2039 gets here ;) |
| 18:52.04 | TomW | yeah, you hear the story about Dennis Richie being asked bout the 32bit overflow of the unix clock, he didn't care, he'd be dead by then. |
| 18:53.07 | Russ|werk | sorphin: luckily, its time_t, and time_t is unsigned long |
| 18:53.17 | Russ|werk | so all we have to do is buy some 64 bit machines |
| 18:53.21 | TomW | ok, playtime is over, time for me to get to work. Time to get the ohm meter out and buzz the webpal out some more. |
| 18:53.30 | sorphin | Russ: well, i will, when the Opteron is out :P |

| 19:41.41 | TimRiker | heh |
| 19:41.50 | sorphin | you need to get a #8 screw |
| 19:42.04 | sorphin | inplace of the xbox one where that chip is going :P |
| 19:42.17 | TimRiker | #8 torx right? /me looks.... got T8 here. |
| 19:42.40 | sorphin | when i say #8 i mean size, not T8 |
| 19:42.46 | TimRiker | I thought the Matrix kits included a screw now? I'm I on crack? |
| 19:42.51 | sorphin | i think the board screws are T10s |
| 19:42.55 | sorphin | nope no screw |
| 19:43.01 | sorphin | just a spacer/lock washer |
| 19:43.06 | sorphin | oh |
| 19:43.11 | sorphin | maybe it does, i dunno |
| 19:43.14 | sorphin | didn't when i got it |
| 19:43.18 | sorphin | if it does |
| 19:43.22 | sorphin | you're lucky ;) |
| 19:43.38 | TimRiker | ah. hmmm. well I've not opened the box yet, I'll run to the hw store if need be after it shows up. |
| 19:43.41 | prpplague | ok, i need some to help me a stupid question, what is the difference between a CCFT and CCFL lcd panel, and don't same the T and L! |
| 19:43.55 | sorphin | prpplague: the T and the L :P |
| 19:44.14 | sorphin | actually, i dunno.. never heard of either |

| 19:44.43 | sorphin | TimRiker: if you have to go, take the xbox screw w/ you |
| 19:44.43 | sorphin | to match against |
| 19:44.57 | sorphin | it's i think 1/2 " long |
| 19:45.03 | sorphin | #8 in diameter is what you need |
| 19:45.37 | sorphin | TimRiker: since i used that screw, i've not had it budge at all, unlike some complaints from lusers using the stock screw |

| 19:46.52 | TimRiker | ~ccft is Cold Cathode Fluorescent Tube a type of LCD panel |
| 19:46.54 | | okay, TimRiker |
| 19:47.04 | TimRiker | ~ccfl is also a type of LCD panel |
| 19:47.06 | | okay, TimRiker |
| 19:47.27 | sorphin | ~ccfl |
| 19:47.29 | | hmm... ccfl is Cold Cathode Fluorescent Lamp, or a type of LCD panel |
| 19:47.33 | prpplague | TimRiker: so whats the difference between a tube and a lamp? |
| 19:48.22 | Russ|werk | maybe a lamp can be a tube, not neccessarily? |
| 19:48.40 | TimRiker | http://www.howstuffworks.com/question580.htm |
| 19:48.47 | TimRiker | sounds likely to me. |
| 19:51.09 | *** join/#elinux file (jwired@mctn1-3654.nb.aliant.net) |
| 19:52.12 | TimRiker | from what I can read, it's just the light type on the panel. the panel interface would presumably be the same. It sounds like a ccft is a ccfl but that there might be other "lights" other than tubes. Can't think of a current practical one for color, but the green lights on bw panels might qualify? |
| 19:56.37 | prpplague | TimRiker: well it looks like both the CCFT and CCFL |

| 23:19.45 | Lethal | MonMotha, I wish I was |
| 23:19.53 | MonMotha | now THAT is pathetic |
| 23:20.04 | Aelhaz | there was a guy who was that dumb, but i figure it was the heroin more than anything else |
| 23:20.25 | Aelhaz | there's button pushers, and then there's people who find bugs in device drivers and board ports. |
| 23:20.59 | Aelhaz | unfortunately these have the exact same job description, so it doesn't look any better on a resume |
| 23:21.06 | Lethal | there's always good and bad QA. more bad then good from the looks of things. |
| 23:21.09 | MonMotha | anyone know a cheap source of (small) CF cards? |
| 23:21.15 | MonMotha | in small quantities |
| 23:21.32 | Aelhaz | MonMotha: newegg.com hasn't been bad in the past . . . |
| 23:21.46 | MonMotha | Aelhaz: which reminds me, I need to put that kfree in my patch to wheaties.c |
| 23:21.48 | Lethal | this requiring a CS degree thing is probably just a lame attempt to purge a large number of useless applicants. the drawback of course is that you take out some useful ones as well. |
| 23:22.18 | Aelhaz | Lethal: I figure HR people are asking managers what they'd like to see in a candidate, and then putting it in the ad |
| 23:22.36 | Lethal | Aelhaz, that's probable too. I don't think I'd wand a coder as a QA person though ;P |
| 23:22.49 | Aelhaz | Lethal: there's a city PD here that wants a network administrator with an associates degree in criminology, a background in social sciences, and the ability to lift 50 pounds regularly |
| 23:22.56 | Aelhaz | Lethal: for $17/hr |
| 23:23.01 | Lethal | hah |
| 23:23.33 | Aelhaz | Lethal: Well, the thing is, management always wants QA to do things that require new code |
| 23:23.44 | Aelhaz | Lethal: and engineering will never, ever, under any circumstances, provide said code |
| 23:24.22 | Aelhaz | so you find yourself wishing you could get a CS intern or something |
| 23:24.22 | Aelhaz | but it never happens |
| 23:24.26 | Lethal | Aelhaz, well, QA should have some rough idea of code, or at least be able to pump out testsuites or other usability things, but I don't think its useful past that. |
| 23:25.11 | Aelhaz | right, and i used to do that. But once upon a time they wanted me to stress-test the double-buffering ability of a framebuffer driver for a low-rez LCD screen |
| 23:25.18 | Lethal | but I can definitely see the problem with engineering providing code. I've had to help out QA a couple of times at work, and I _hate_ doing QA stuff. :P |
| 23:25.20 | Aelhaz | how in the heck was i going to do that? |
| 23:26.03 | Aelhaz | nothing i can throw into a bash script is going to do squat to stress it |
| 23:26.14 | prpplague | Aelhaz: i was just looking for a url for this sysadmin who had a QA/help desk person who was a nightmare |
| 23:26.18 | Aelhaz | and my ability to grok c is extremely fuzzy |
| 23:26.45 | Aelhaz | I understand the syntax, I just can't follow the logic. It's not the way my brain works, I have other talents. |
| 23:27.32 | prpplague | Aelhaz: cooking pizza? |
| 23:27.51 | Aelhaz | what, right now? no. |
| 23:27.55 | Aelhaz | i should be so lucky. |
| 23:28.33 | Aelhaz | actually, I make damn fine pizza, from scratch. but knowing how to cook is actually an excellent way to prevent yourself from being hired at a pizza joint. |
| 23:28.54 | prpplague | Aelhaz: when i open my nudiebar/english pub/electronics parts/software development/open source think tank, you can come work for me, i'm sure we will have alot of QA on the nudie bar side |
| 23:28.58 | Aelhaz | they don't want people who know how to go from a can of sauce, a block of cheese, and a bag of flour to product |
| 23:29.02 | Aelhaz | they want people they can train |
| 23:29.19 | Aelhaz | prpplague: Wouldn't mind slinging pizza, either |
| 23:30.38 | Aelhaz | I used to make dough for pizzahut. Worst. Job. Ever. |
| 23:30.43 | Aelhaz | everybody hates the dough guy. |
| 23:31.00 | Aelhaz | the cooks hate the dough guy because there is either too much or too little |
| 23:31.30 | Aelhaz | the drivers hate the dough guy because sometimes dough sticks to the pans - even though technically that's their fault, since they grease the pans before they go home the night before |
| 23:31.47 | MonMotha | anyone know if a replacement for the CDP6402, AY-5-1015, or D36402R-9 UART was ever made? The only UARTs I can find these days assume you have a uP to hook it up to |
| 23:32.01 | prpplague | Aelhaz: thats ok, you can have fun with the dough, lol |
| 23:32.21 | Aelhaz | the manager hates the dough guy because the dough guy needs a frigging key to the store if you expect him to show up at 5am |
| 23:33.06 | Aelhaz | and the manager for some reason can't stand giving people keys, because they get lost, and then they have to get new keys made. |
| 23:33.33 | Aelhaz | I worked at three huts, and at each one i was expected to open the store in the morning without a key. I never figured out how that was supposed to work. |
| 23:33.44 | Lethal | Aelhaz, a rock |
| 23:34.05 | Aelhaz | they'd say, "You need to be here at 5 tomorrow" |
| 23:34.14 | Aelhaz | I'd say, "Sure thing, boss. I'll need a key" |
| 23:34.20 | Aelhaz | they'd say, "We don't have a key for you" |
| 23:34.51 | Aelhaz | I'd say, "Then I'll be here at 8, so you can unlock the door for me. Unless you want to come out at 5." |
| 23:34.54 | Aelhaz | they didn't like that. |
| 23:36.09 | Lethal | Aelhaz, so thats why you were at 3 different ones ;P |
| 23:36.18 | Aelhaz | The phone people probably didn't hate me, I doubt they knew i existed |
| 23:36.41 | Aelhaz | Lethal: oddly enough i was fired twice, and both times picked up work at another hut within hours |
| 23:37.14 | Aelhaz | Usually a matter of politics |
| 23:37.21 | Aelhaz | the first two times, I worked for unpopular bosses |
| 23:37.30 | Aelhaz | "So and so fired you? Man, it'd really piss her off if i hired you" |
| 23:39.05 | prpplague | lol |
| 23:41.07 | Aelhaz | the aparant reality is that pizza delivery units steal delivery territory from eachother every few years, so they all hate eachother |
| 23:41.23 | Aelhaz | even within sets that all belong to the same guy |
| 23:42.18 | Aelhaz | they don't really "steal" territory, they go to regional management and say, "If we had these 8 blocks, we'd be more profitable, and so-and-so can hardly deliver to that neighborhood anyway, so it will increase customer satisfaction" |
| 23:54.32 | prpplague | argh, this is driving me insane! |
| 23:54.40 | Aelhaz | what are you working on? |
| 23:54.41 | prpplague | i hate losing url's |
| 23:54.59 | sieve | night all |
| 23:55.04 | prpplague | Aelhaz: i've lost this url for about the help desk moron |
| 23:56.12 | prpplague | gotta run |
| 23:56.18 | prpplague | later folks |
