| 00:04.36 | prpplague | joe_bleau: i have a couple of choices |
| 00:04.43 | joe_bleau | CCFL lamps on the outside? |

| 00:05.47 | prpplague | thats the one i like the mosst |
| 00:06.17 | joe_bleau | Yeah, decent keyboard, expansion slot, 4 AA batts. |

| 00:06.48 | prpplague | thats ones nice but doesn't have the function keys |
| 00:06.53 | joe_bleau | Is that a printed graphic outside the LCD area on the first one? |
| 00:06.59 | prpplague | joe_bleau: yea |
| 00:07.34 | joe_bleau | Oh, a thermal printer? Interesting. |
| 00:07.43 | prpplague | joe_bleau: this one is interesting - http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=6052623808&rd=1&sspagename=STRK%3AMEWA%3AIT&rd=1 |
| 00:08.00 | prpplague | joe_bleau: it has a touch screen, and the upper panel can be detached |
| 00:08.05 | prpplague | joe_bleau: like a web pad |
| 00:08.41 | joe_bleau | Yep. Decent pricing, it sounds like. Do you have an idea what's inside? I'm guessing 8 bit micro... |
| 00:09.24 | prpplague | joe_bleau: yea almost all have some type of 8051 style device |
| 00:09.43 | prpplague | joe_bleau: main thing i was interested in was a small lcd that i could use |
| 00:10.04 | joe_bleau | What size/res are these, do you think? |
| 00:10.49 | prpplague | joe_bleau: general these things range from 32x32 to mid size of 94x32 |
| 00:10.59 | joe_bleau | pixels? |
| 00:11.01 | prpplague | joe_bleau: with the max of about 128x64 |
| 00:11.05 | prpplague | joe_bleau: yea |
| 00:11.21 | joe_bleau | B.G. Micro has something like that on sale, with controller/driver. |
| 00:11.32 | joe_bleau | $10 or so, backlit. I've been tempted. |
| 00:11.35 | prpplague | joe_bleau: oh yea? |

| 00:11.51 | prpplague | joe_bleau: that one is kinda of trendy |

| 00:13.22 | joe_bleau | Might be trendy (I wouldn't know), but the screen seems smaller than the others. |
| 00:13.56 | prpplague | joe_bleau: HO lovely thats what i've been looking for |
| 00:13.59 | prpplague | joe_bleau: thanks |
| 00:14.12 | joe_bleau | You're quite welcome. BGM is good people. |
| 00:16.26 | prpplague | bummer 3.5v min for a high value |
| 00:16.31 | joe_bleau | All it's missing is a LCD controller: http://microcontroller.com/news/dualcore_DCIC9907.asp |
| 00:16.38 | prpplague | would have to use some sort of buffer |
| 00:18.32 | prpplague | hmm, i'll keep that one in mind |
| 00:20.04 | prpplague | 128x64 might do well |
| 00:20.33 | prpplague | hmm, with a 4x6 font thats just 32 chars across |
| 00:20.43 | joe_bleau | Yep, sounds kinda tight. |
| 00:21.16 | prpplague | joe_bleau: yea i planned for it to be small |

| 00:22.47 | joe_bleau | Onboard char generator? |
| 00:23.17 | prpplague | joe_bleau: yea there is a 5x7 fonts |
| 00:23.26 | joe_bleau | I've got some panels with a T6309 (mumble) controller. Easy to use. |
| 00:23.27 | prpplague | joe_bleau: but i would use it in graphics mode |
| 00:23.34 | prpplague | joe_bleau: yea? |
| 00:23.47 | joe_bleau | Yeah. Probably about the same size. |
| 00:24.24 | joe_bleau | T6963 sounds more like it. |
| 00:26.59 | prpplague | joe_bleau: hehe i knew what you ment |
| 00:28.07 | prpplague | if i use the one from allelectronics, i'll have to use a couple of 245's |
| 00:28.23 | joe_bleau | I didn't see...was it backlit? |
| 00:30.07 | prpplague | no no backlight |
| 00:30.29 | joe_bleau | Pass on it then. Find one with a backlight...much sexier. |
| 00:30.42 | prpplague | hehe |
| 00:31.03 | prpplague | really had to find what i need |
| 00:31.19 | joe_bleau | Do you need onboard controller? |
| 00:31.29 | prpplague | yea |
| 00:31.39 | joe_bleau | If not, strip something from a JB or Pixter or whatever. |
| 00:31.42 | prpplague | joe_bleau: don't ask, can't tel |
| 00:31.54 | prpplague | joe_bleau: yea that was my first thought |
| 00:32.06 | prpplague | joe_bleau: but i need something that i can parallel bit bang |
| 00:32.10 | joe_bleau | I wonder if the color LCDs from the newer Palms are cheap yet. |
| 00:32.34 | joe_bleau | Oh, so you need the controller. OK. |
| 00:32.47 | prpplague | joe_bleau: yea doing this to demo a core |
| 00:47.23 | prpplague | joe_bleau: which laptop did you like the best? |

| 01:34.38 | prpplague | joe_bleau: which one of the laptops did you like the most? |

| 01:39.30 | joe_bleau | I dunno. Don't like the 'trendy' one, as the screen looks too small. No preference between the others. |
| 01:40.01 | prpplague | joe_bleau: yea i'll probably hack a new screen into whatever i get |

| 03:28.25 | jbevren | hmm |
| 03:28.31 | joe_bleau | Hmm, indeed. |
| 03:28.32 | jbevren | opengl doesnt make a half-bad video scaler |
| 03:28.35 | jbevren | hehe |
| 03:28.49 | jbevren | now if I could only get sata and my dvdrom working at the same time |
| 03:28.51 | jbevren | hehe :) |
| 03:29.02 | joe_bleau | sata on an octane? |
| 03:29.06 | jbevren | nope |
| 03:29.10 | jbevren | PC laptop |
| 03:29.17 | jbevren | my octane doesnt have TRAMs :( |
| 03:29.27 | joe_bleau | Neither does mine. |
| 03:29.29 | jbevren | ati's drivers dont have Xv support |
| 03:29.44 | jbevren | so I thought I'd try xine's opengl video backend |
| 03:30.05 | jbevren | anyway, the harddisk is sata, and the dvdrom is apparently pata |
| 03:30.26 | jbevren | that's low priority tho, I have all the important stuff working |
| 03:30.34 | jbevren | but talk about your no-frills audio driver :) |
| 03:30.42 | jbevren | volume, mic, line |
| 03:30.44 | jbevren | thats it heh |
| 03:51.07 | jbevren | joe_bleau: I have better luck playing video on my O2 |
| 03:51.11 | jbevren | what's your octane setup? |
| 03:51.52 | joe_bleau | I dunno. I did the el cheapo R12k upgrade, 512MB, SI. |
| 03:52.24 | joe_bleau | No PCI, no XIO cards. |
| 03:52.44 | jbevren | 300mhz? |
| 03:52.50 | joe_bleau | It is now... |
| 03:52.53 | jbevren | using irix or? |
| 03:52.54 | joe_bleau | (resistor mod) |
| 03:52.57 | jbevren | mine's 300mhz.. |
| 03:53.00 | joe_bleau | Yep, 6.5.something |
| 03:53.06 | jbevren | what player? (20 questions mode) |
| 03:53.11 | jbevren | :D |
| 03:53.15 | joe_bleau | Player? |
| 03:53.20 | jbevren | video player |
| 03:53.27 | joe_bleau | don't know. |
| 03:53.30 | jbevren | hehe |
| 03:53.41 | jbevren | I mentioned opengl being a good scaler, and you first mentioned the octane |
| 03:53.44 | joe_bleau | I used it more for audio hacking. Haven't powered it up in two months. |
| 03:53.47 | jbevren | so I figured you had a setup for it :) |
| 03:53.58 | joe_bleau | openGL -> SGI in my mind. |
| 03:54.08 | jbevren | grrI really need to get my freq scaler working |
| 03:54.19 | joe_bleau | I wanted to do some openGL hacking on it, but had trouble getting glut going with gcc |
| 03:54.26 | jbevren | ah |
| 03:54.47 | jbevren | I typically use my O2 for vidcap when I actually bother |
| 03:55.01 | jbevren | although I still cant figure out how to get it to use MACE for encoding |
| 03:55.39 | joe_bleau | I just wish the octane wasn't so freakin' noisy. |
| 03:56.17 | jbevren | nod |
| 03:56.24 | jbevren | do you have the cherokee psu? |
| 03:56.35 | joe_bleau | I have the old one. |
| 03:56.38 | jbevren | I'm told theyre quieter |
| 03:56.47 | jbevren | mine's cherokee, its not TOO bad, but it could still be quieter |
| 03:56.56 | joe_bleau | mine has a black handle |
| 04:02.43 | jbevren | ok I give up for the night |
| 04:02.45 | jbevren | enjoy |

| 16:28.21 | sorphin | T0mW: hey gramps |
| 16:28.35 | T0mW | morning |
| 16:29.01 | sorphin | T0mW: how's things in .pa.us ? |
| 16:29.58 | T0mW | eh, not bad, a few brush fires around the area as it has been pretty dry. |
| 16:30.03 | sorphin | ah |
| 16:30.58 | T0mW | other than that, the flowers are coming up, the dresses are appearing. heh |
| 16:35.27 | prpplague | T0mW: hey |
| 16:37.37 | T0mW | prpplague: what's up dude? |
| 16:38.59 | prpplague | T0mW: nada, work work work |
| 16:39.13 | prpplague | T0mW: you ever do much with lcd's using stuff like the sed1330 |
| 16:39.15 | prpplague | T0mW: ? |
| 16:40.57 | T0mW | prpplague: not much call for that in my line of work. |
| 16:42.07 | prpplague | T0mW: yea, didn't think so |
| 16:43.20 | T0mW | prpplague: I think that a customer of mine uses an ElectroLuminescent display with a similar chipset. From what I've seen, it is a PITA to work with. It has a graphics plane and a text plane, and these can overlap? |
| 16:43.39 | prpplague | T0mW: hmmm |
| 16:45.29 | T0mW | prpplague: AFAICT, it is mainly built for systems that don't have enough power to run a real lcd controller (DMA). |
| 16:45.52 | prpplague | yea |
| 16:46.06 | prpplague | T0mW: basically its just a small 8bit parport lcd controller |
| 16:46.16 | T0mW | heh, yes |
| 16:48.57 | prpplague | T0mW: just tinkering around with some stuff |
| 16:52.12 | T0mW | prpplague: parts are in, the board was shipped Monday, the stencil should go out today.. I'll be messing with another board this weekend I guess. |
| 16:52.49 | T0mW | now, if I can only get some of this other work done, then I can go play. |
| 16:53.03 | T0mW | :) |
| 16:53.18 | prpplague | T0mW: i have so much coding to do it isn't even funny |
| 16:54.36 | prpplague | interesting |
| 16:54.54 | prpplague | the kids educational laptop that was sold 4 years ago boasts: |
| 16:55.07 | prpplague | "Dual Processor with built-in ROM and RAM" |
| 16:55.19 | prpplague | wonder what processors they are |
| 16:55.34 | prpplague | the lcd is suppose to be 20,000 pixels |
| 16:55.41 | prpplague | my guess is 160x128 |
| 16:55.43 | T0mW | heh, ARM7TDMI + SED1330 ? |
| 16:56.01 | prpplague | T0mW: arm920t + sed1335 |
| 16:56.42 | prpplague | T0mW: you use hct245's when you need to do 3.3v to 5v level shifting? |
| 16:58.28 | T0mW | depends on the application. If it is a bus driver / buffer for a high speed path, I like the LVCT series of logic: true 3v/5v interface. Otherwise, for general purpose work, yeah, HCT will do. |
| 16:59.12 | prpplague | T0mW: ahh, basically some of the lcd's i was tinkering with have 5v logic |
| 17:00.04 | prpplague | T0mW: http://www.bgmicro.com/prodinfo.asp?sid=04580787037037047222137214&prodid=LCD1030&page=1&cri=lcd&stype=3 |
| 17:00.31 | T0mW | IIRC, HCT will switch at 2v for a high, but you have to be carefull of the output level. The output level can be as much as 4volts, depending. At 4 volts you are overdriving 3volt logic (3.3 + 10% == 3.63v) |
| 17:01.15 | T0mW | HCT can be used to drive 5volt logic from 3v stuff. |
| 17:01.43 | T0mW | going the other way, you may have to put some 10ohm series resistors in the lines. |
| 17:01.53 | prpplague | T0mW: yea, this would be all output iirc |
| 17:03.23 | T0mW | what you want to watch out for is feedback from the 5v supply into the 3v supply via the port pins. Although current can be small, it does cause heating inside the i/o and degrade the lifetime of the port logic. |
| 17:03.36 | prpplague | ahh |
| 17:03.47 | T0mW | sort of like charging a battery |
| 17:04.28 | T0mW | even though a processor says "5v tolerant pins", that is what happens. |
| 17:04.41 | T0mW | the excess voltage has to go someplace |
| 17:06.21 | T0mW | prpplague: I think that I ran into that for the first time with the Mot 68EZ328 processor. Motorola said the pins were 5v tolerant but that using them in that fashion would degrade their lifetime. Most 3v logic will not tolerate an overload and let the smoke out. |
| 17:16.26 | prpplague | i'm dying to find out whats inside this kids laptop |
| 17:20.14 | T0mW | Mandriva2006 gets up to installing the bootloader then bails out complaining it cannot find shorewall (stupid a$$ firewall). |
| 17:20.50 | T0mW | I don't want their stupid firewall, I have my own |
| 17:29.54 | jbevren | doh! |
| 17:33.27 | T0mW | neither "shorewall" or "mandi-ifw" is in the rpmsrate... |
| 17:33.44 | T0mW | nor are either of them in the gi |
| 17:34.39 | T0mW | sheesh, all we need is a "helpful" linux distro (a.k.a. Microsoft wizzards) |
| 17:48.08 | T0mW | more than one way to do this |
| 17:48.21 | T0mW | gut the package |
| 17:58.41 | prpplague | T0mW: hey, i'm tinkering with a project, might need you to mentor me on the pcb stuff |
| 17:59.20 | T0mW | np |
| 17:59.36 | T0mW | worst is the CAM operations: gerber and excellon drill files |
| 18:00.26 | T0mW | prpplague: get a copy of GCPREVUE from someplace, it only runs on Windows. I run it on Win98SE |
| 18:01.08 | prpplague | T0mW: the gnu layout stuff has an equivilant to gvprevue |
| 18:02.06 | T0mW | :/ |
| 18:02.22 | T0mW | I have yet to find an equivilant to gcprevue |
| 18:03.14 | T0mW | as far as that goes, I have yet to find an open source package that will do a good job of PCB design. Most are lacking in some respects. |
| 18:03.40 | prpplague | T0mW: yea i'm using the eagle cad linux |
| 18:03.58 | T0mW | then stay with that, it is what I use and works for me. |
| 18:05.21 | T0mW | prpplague: probably the worst thing to learn is the library stuff. You really have to master that as you will find that you don't have all the footprints for devices and will have to make some. |
| 18:05.26 | T0mW | and |
| 18:05.40 | T0mW | there are devices missing, such as LPC2000 ARM, etc. |
| 18:05.58 | T0mW | prpplague: pretty straight-forward though |
| 18:07.32 | prpplague | T0mW: yea, i just need simple power supply stuff |
| 18:07.39 | prpplague | T0mW: plus maybe a tsop |
| 18:07.49 | prpplague | T0mW: those 245's |
| 18:09.12 | prpplague | T0mW: gonna shove a s3c2410 into this - http://i12.ebayimg.com/05/i/06/e4/56/83_1.JPG |
| 18:09.30 | T0mW | There are a few cheap PCB houses. One I was dealing with for the ZipIt addon board, they did alright, but the quality was iffy on some of the boards. So, for a "real" board, I went with 4pcb.com. They do a nice job! |
| 18:10.21 | T0mW | prpplague: wtf is that thing? |
| 18:11.22 | jbevren | tom: youve seen them at walmart |
| 18:11.30 | jbevren | theyre the kiddy computers that teach math, spelling, etc |
| 18:14.47 | T0mW | jbevren: prpplague's son is pissed 'cause his Dad disassembled another one of his toys! |
| 18:15.01 | jbevren | lol |
| 18:15.04 | prpplague | hehe |
| 18:15.17 | prpplague | not really since i buy the toys for me |
| 18:15.22 | prpplague | hehe |
| 18:15.48 | prpplague | T0mW: that laptop thingy cost $20 on ebay |
| 18:15.55 | prpplague | T0mW: has lcd and keyboard |
| 18:16.04 | prpplague | T0mW: 4 AA size battery slots |
| 18:16.21 | prpplague | T0mW: gonna see what i can do with it |
| 18:16.51 | prpplague | goal is to get it working enough to use a irc client with a 802.11 dongle |
| 18:20.19 | T0mW | suspiciously, that graphic looks like a big cardboard panel with a smaller BW LCD inside of it? |
| 18:20.26 | jbevren | precisely |
| 18:20.32 | jbevren | my sister kept getting them for her kids |
| 18:20.37 | T0mW | oh, it is? |
| 18:20.39 | jbevren | so I gave her a commodore 64 :) |
| 18:20.44 | T0mW | LOL |
| 18:20.46 | jbevren | they -loved- the c64 |
| 18:20.48 | T0mW | a stop up |
| 18:20.52 | jbevren | oh yeah |
| 18:20.54 | jbevren | programmable too heh |
| 18:20.56 | T0mW | a step up even |
| 18:21.02 | jbevren | my nephew made some small basic games |
| 18:21.05 | T0mW | better games |
| 18:21.12 | jbevren | more color, better audio :) |
| 18:21.35 | T0mW | yeah, the Color LCDs are quite expensive |
| 18:23.35 | prpplague | T0mW: yea its just a small graphics display |
| 18:23.42 | prpplague | T0mW: specs say 20,000 pixels |
| 18:23.51 | prpplague | T0mW: which i'm willing to bet is 160x128 |
| 18:23.59 | T0mW | exactly |
| 18:24.33 | T0mW | I'll stick with the zipit, at least it has an 802.11b wifi installed |
| 18:25.32 | prpplague | T0mW: hehe, well, i have a reason for doing this |
| 18:25.44 | prpplague | T0mW: gonna show off a new s3c2410 board |
