| 07:32.09 | RobotGuy | Howdy |
| 08:26.47 | methril | morning |
| 08:28.42 | RobotGuy | G'Morning? |
| 08:29.15 | RobotGuy | Well, OK, it is 1:28 AM here. Technically, that qualifies as morning. |
| 08:31.52 | methril | hehehe |
| 08:32.04 | methril | you got to bed late |
| 08:32.52 | RobotGuy | I slept earlier, woke up at 7:00 PM |
| 08:33.58 | methril | hehehe |
| 08:38.34 | RobotGuy | It's been real warm here, so I sleep as I can. |
| 08:39.20 | RobotGuy | I am going to a convention next week. It's OSCON. |
| 08:42.29 | RobotGuy | All week long. |
| 08:44.22 | methril | and there you stay in a hotel with air :) |
| 08:57.51 | RobotGuy | I don't have to travel to get there other than taking a bus and MAX train. :) |
| 08:58.18 | RobotGuy | I live about 20 - 25 miles from Portland. |
| 09:15.13 | *** join/#edev lyakh (n=lyakh@p57BD27C9.dip0.t-ipconnect.de) |
| 09:22.50 | methril | one question about uP/uC |
| 09:23.08 | methril | i have to chooose one, and the first step, i don't know if it's the architecture |
| 09:23.57 | RobotGuy | What is your application? |
| 09:34.48 | methril | here they want to develop a modular arch, to use with for more than one app |
| 09:35.41 | methril | we'd like LCD (2D) and some encription capabilities |
| 09:36.11 | methril | the rest, the usually I2C, SPI, UARTs, USB and Ethernet |
| 09:40.06 | RobotGuy | Is this for a particular or generic device? |
| 09:41.01 | RobotGuy | Encryption can be done in software. |
| 09:42.01 | RobotGuy | Except the Ethernet, which could be easily added, A Hammer Kit has what you are asking for. I have full Python on my Hammer now. |
| 09:42.41 | RobotGuy | Also a web server and web framework (DJango, written in Python), and an IRC Bot also written in Python. |

| 14:34.59 | chouimat|work | so I don't want to imagine what 32GB looks like ... but I would like to have that kind of memory |
| 14:35.23 | chouimat|work | g1powermac_PB: now the computer feel fast |
| 14:35.39 | g1powermac_PB | heh, you know, that may be just enough to run firefox 2 for about two months straight ;-) |

| 14:36.14 | chouimat|work | g1powermac_PB: this mean you can have a lot of eye candies |
| 14:36.40 | g1powermac_PB | meh, I just want to render video graphics in real time :-) |
| 14:37.17 | chouimat|work | g1powermac_PB: I think for my birthday next february I will buy the missing 24GB ... |
| 14:37.29 | g1powermac_PB | my iMac was a massive leap over my ancient 867mhz G4 powerbook, but now the imac is getting limiting |
| 14:37.56 | chouimat|work | g1powermac_PB: I still have my 1ghz ibook g4 |
| 14:38.09 | g1powermac_PB | yup, I still got my powerbook, I'm on it right now :-) |
| 14:38.18 | g1powermac_PB | hence, the _PB at the end of my nick :-) |
| 14:39.34 | g1powermac_PB | man, I really could spend like $20k on the stuff I'd like to get. . . |
| 14:40.12 | RobotGuy | Both my PCs are very outdated for what I need. |
| 14:40.22 | g1powermac_PB | mac pro, new hd camcorder, maybe new macbook pro |
| 14:40.42 | g1powermac_PB | audio equipment, two lcd panels for the dev machine. . . |
| 14:41.02 | chouimat|work | g1powermac_PB: same here but I will go for a new drums set |
| 14:41.09 | g1powermac_PB | ahh, nice |
| 14:41.19 | g1powermac_PB | used to play the drums way back when |
| 14:41.21 | chouimat|work | but I will need a house for this |
| 14:41.51 | g1powermac_PB | I got myself a guitar a while back that I'd like to learn to play |
| 14:44.10 | g1powermac_PB | does enjoy hacking cheap things together to make stuff that would normally be fairly expensive |
| 14:44.19 | g1powermac_PB | like my studio light system |
| 14:50.09 | g1powermac_PB | this is my next camcorder though; http://www.amazon.com/Canon-XL-H1A-Definition-Professional-Camcorder/dp/B0016PPMRY/ref=pd_bbs_sr_6?ie=UTF8&s=electronics&qid=1216306031&sr=8-6 |
| 15:03.00 | RobotGuy | That's only about 1/2 year income for me. |
| 15:04.43 | g1powermac_PB | *sigh* just got the bloodwork report back. . .another one of my liver enzymes are elevated |
| 15:05.54 | RobotGuy | wonders what to do with the old chair when he gets a new one. |
| 15:06.24 | RobotGuy | There is a $60.00 motor controller that will handle the motors. |
| 15:08.04 | RobotGuy | It might be fun turning it into a robot base. Hmmmmmmm. |

| 16:20.37 | T0mW | this is true, I signed so many papers yesterday that I may have signed my eternal soul away |
| 16:20.48 | g1powermac_PB | and your first born :-) |
| 16:21.36 | T0mW | now, the FICO score be damned, it is time to start using some of that credit to start work on getting this place habitable. |

| 16:24.24 | RobotGuy | considers what he could do with a couple Hammers and a power wheelchair base |
| 16:24.40 | CosmicPenguin | that sounds like an episode of Jackass |
| 16:25.26 | RobotGuy | Yeah, I guess it does! :P I'm speaking of the electronic variety of Hammer though. |

| 16:26.22 | g1powermac_PB | meh, I like madtv's recreation of that movie with kenny rogers ;-) |

| 16:27.35 | T0mW | RobotGuy: foreclosure |
| 16:28.00 | RobotGuy | How not habitable is it. |
| 16:28.09 | T0mW | RobotGuy: AFICT, they didn't properly winterize the house and there may be probs with the water pipes |
| 16:28.25 | RobotGuy | Uh oh. |
| 16:28.26 | kergoth`work | morning |
| 16:28.27 | CosmicPenguin | the bank didn't winterize it? |
| 16:28.34 | kergoth`work | T0mW: grats on the house |
| 16:28.38 | g1powermac_PB | T0mW: hrmm, that isn't good |
| 16:28.56 | RobotGuy | Nobody going to OSCON next week? |
| 16:29.02 | prpplague | T0mW: i'm sorry |
| 16:29.39 | prpplague | hates owning a house |
| 16:29.57 | kergoth`work | i like owning a house.. but then i'm renting it, so someone else is paying my mortgage |
| 16:30.01 | CosmicPenguin | loves equity |
| 16:30.04 | RobotGuy | doesn't own a house and most likely never will. |
| 16:30.20 | g1powermac_PB | would like to build his own house. . . |
| 16:30.28 | kergoth`work | if i buy another, it will likely be a 15 year mortgage and then pay double every month to pay it off in 7 years.. or at least pay a few extra times a year |
| 16:30.31 | g1powermac_PB | out of concrete. . . |
| 16:30.35 | kergoth`work | and then rent it out when i move again |
| 16:31.13 | T0mW | kergoth`work: yeah, but, you can cut holes in the walls and nobody cares |
| 16:31.22 | kergoth`work | hehe |
| 16:31.32 | prpplague | CosmicPenguin: equity doesn't compensate for all the hassles |
| 16:31.34 | g1powermac_PB | T0mW: hehe, we can do that now, the landlord we have really doesn't care :-) |
| 16:31.43 | CosmicPenguin | prpplague: life is a hassle |
| 16:31.44 | g1powermac_PB | T0mW: just as long as it looks nice in the end :-) |
| 16:32.16 | prpplague | CosmicPenguin: alot less hassle with an apartment |
| 16:32.24 | g1powermac_PB | T0mW: I never changed out so many things in this rental house we're living in now |
| 16:32.25 | prpplague | or even a townhouse/condo |
| 16:32.25 | kergoth`work | and then you're throwing your money away |
| 16:32.36 | CosmicPenguin | I guess it depends on what your priorities are |
| 16:33.05 | RobotGuy | It seems like owning a condo is just owning an apartment. |
| 16:33.14 | prpplague | kergoth`work: i hear people say that, but i see HOA dues, property taxes , yard equipment, trash service as throwing money away |
| 16:33.20 | T0mW | g1powermac: heh, real luxury apartment, eh? |
| 16:33.27 | kergoth`work | property taxes are tax deductable |
| 16:33.35 | kergoth`work | trash service is minimal |
| 16:33.51 | kergoth`work | don't need yard equipment if you pay a yard service company, or go with a townhouse or condo |
| 16:33.54 | g1powermac_PB | T0mW: nah, just an older house who's ceiling fans and other light fixtures were really needing replacement |
| 16:33.59 | CosmicPenguin | HOA dues increase the value of your home |
| 16:34.09 | kergoth`work | and the house is likely to appreciate, which will easily compensate for all those miniscule expenses |
| 16:34.12 | g1powermac_PB | ugh, HOAs suck |
| 16:34.17 | kergoth`work | (at least once the hosuing market gets out of the shitter) |
| 16:34.33 | prpplague | like i said, those are things i'd rather not deal with |
| 16:34.43 | g1powermac_PB | though it could've been just the insane person that was running the HOA we had. . . |
| 16:34.46 | CosmicPenguin | Selling a house in a HOA controlled neighborhood is likely to pay you back every penny you put into the HOA |
| 16:35.06 | T0mW | prpplague: I only have one thing to say: I have handed over > $50K to my landlord in the past 12 years... |
| 16:35.33 | T0mW | equity |
| 16:35.37 | g1powermac_PB | she'd put liens on everyone's house the day after your HOA payment was due |
| 16:35.51 | CosmicPenguin | hah |
| 16:36.05 | kergoth`work | yikes |
| 16:36.08 | CosmicPenguin | That chick needs a job |
| 16:36.11 | prpplague | CosmicPenguin: i'm sure it does |
| 16:36.14 | g1powermac_PB | then there was lots of other crap that went on |
| 16:36.25 | g1powermac_PB | like harrasment over our ebay business we had |
| 16:37.06 | prpplague | CosmicPenguin: kinda of moot point anyway, my wife wants a house, so i have to have one :( |
| 16:37.46 | T0mW | prpplague: every bird needs a nest to feather, heheh |
| 16:38.11 | CosmicPenguin | what an interesting expression |
| 16:40.07 | RobotGuy | renames Hammer-RDP to Mallet |
| 16:43.49 | RobotGuy | I'm taking non-operational W.A.L.T.E.R. to OSCON with me. |
| 16:46.59 | RobotGuy | needs a replacement for mdev |
| 16:47.27 | RobotGuy | Thumb Drive isn't being properly detected and device files not created. |
| 16:48.17 | RobotGuy | I was reading about udev, but it says that wouldn't be appropriate and most use hal. |
| 16:48.42 | RobotGuy | That's fine for a regular PC, but I don't think it would be appropriate for an embedded system. |
| 16:48.53 | RobotGuy | Too many dependencies. |
| 16:49.32 | prpplague | RobotGuy: i've tested mine on the nail heavily, and i have zero problems |
| 16:49.51 | RobotGuy | prpplague: Using mdev? |
| 16:50.08 | prpplague | RobotGuy: no, static dev |
| 16:50.17 | prpplague | no reason to use mdev |
| 16:50.30 | RobotGuy | I was wondering about that. |
| 16:50.44 | RobotGuy | Seems like mdev just overcomplicates things. |
| 16:51.47 | kergoth`work | i could see mdev fro an embedded device that has a usb host, and if you don't really know what devices may be plugged in |
| 16:51.49 | kergoth`work | beyond that.. |
| 16:52.41 | CosmicPenguin | static dev is a pain though |
| 16:52.48 | CosmicPenguin | the concept of udev fits embedded very well |
| 16:52.54 | CosmicPenguin | the implementation may not |
| 16:53.00 | CosmicPenguin | but that can be improved |
| 16:53.06 | mnemoc | hotplug2 is nice |
| 16:53.28 | prpplague | yea, i'm not saying that udev/mdev don't have their uses, i generally design for a specific application |
| 16:53.58 | kergoth`work | on another note, if you guys are like me in needing quick references for everything, http://www.gnugeneration.com/books/linux/2.6.20/kernel-api/ is nice |
| 16:54.14 | prpplague | oh nice |
| 16:55.45 | kergoth`work | looks like it has the important structures too, i.e. http://www.gnugeneration.com/books/linux/2.6.20/kernel-api/re376.html |
| 16:56.40 | RobotGuy | kergoth: Well, that is kind of the situation I have, but I will know what devices will be plugged in. They just may not all be plugged in at the same time or in the same order. |
| 16:56.46 | kergoth`work | converted it to lrf to read on his sony ebook reader |
| 16:58.23 | RobotGuy | CosmicPenguin: Why is static dev a pain? |
| 16:59.40 | CosmicPenguin | RobotGuy: a number of reasons - its time consuming, its difficult to maintain on machines with dynamic packages |
| 16:59.40 | kergoth`work | anyone remember how to make gdb show assembly inline with a function code listing (list)? |
| 16:59.51 | CosmicPenguin | it uses up inodes needlessly |
| 17:01.01 | kergoth`work | man i loev this book reader but i wish it refreshed faster and handled pdfs better :| |
| 17:01.25 | RobotGuy | CosmicPenguin: I don't think that describes my robot. |
| 17:01.41 | CosmicPenguin | your mistake is assuming that there is one right way to do things |
| 17:02.08 | RobotGuy | It should always have a thumb drive (but not always) and a USB WiFi adapter. |
| 17:02.24 | RobotGuy | CosmicPenguin: No, I just want to find the right way for what I am doing. |

| 18:06.20 | kergoth`work | anyone remember how to dump a backtrace from kernel code, without doing a panic? |
| 18:06.25 | prpplague | virtualy all do these days |
| 18:09.28 | RobotGuy | Do I have to get the firmware module rt73.bin separately? |
| 18:10.03 | prpplague | yea |
| 18:13.53 | RobotGuy | So that would lead me to Edimax or Ralink. |
| 18:15.02 | prpplague | RobotGuy: read the README with the driver it explains how to get the bin file |
| 18:15.02 | GPSFan | prpplague: did you ever get a chance to find the z2.cfg that you used when you tested the jtag pins out? I hope to do some mmore z2 jtag work this weekend, so if you might find it and a good place to attach nSRST I'd be a happy camper... ;>) |
| 18:15.34 | prpplague | GPSFan: sorry no, i've been swamped with this 8050 dev |
| 18:15.42 | prpplague | GPSFan: i'll see if i have time this afternoon |
| 18:16.25 | GPSFan | prpplague: thanks, is there any way I might get a hold of some of the pix you took? |
| 18:17.02 | prpplague | GPSFan: i didn't take any, i just used the ones g1powermac took and marked the jtag/serial on those |
| 18:17.23 | GPSFan | prpplague: I meant the see-thruogh ones. |

| 18:19.37 | prpplague | CosmicPenguin: the s3c24xx uart controllers don't have support for ring indicator or carrier detect, but most people just wire those to gpios |
| 18:19.50 | *** join/#edev bronson (n=bronson@38.97.100.54) |
| 18:20.12 | prpplague | CosmicPenguin: the s3c24xx uart driver doesn't directly support that so people ready the status of those lines via proc entries |
| 18:20.46 | prpplague | CosmicPenguin: i was thinking of adding an option to pass a gpio value for RI and CD via the uart_cfg struct |
| 18:21.31 | prpplague | CosmicPenguin: that sound "acceptable" to the general kernel stuff to you? |
| 18:22.37 | CosmicPenguin | sure |
| 18:25.56 | RobotGuy | prpplague: You mean in the kernel sources? |
| 18:26.28 | prpplague | RobotGuy: ?? |
| 18:31.30 | RobotGuy | prpplague: I don't see any mention of firmware for the RT73 unit I have. |
| 18:33.39 | prpplague | RobotGuy: what kernel version are you using? |
| 18:34.11 | RobotGuy | 2.6.26 |
| 18:37.20 | prpplague | should be able to download it from a dozen or more sites |
| 18:37.40 | ds2 | is there such a thing as a quad, hex, or octal 1.8V CMOS level buffer with open collector/drain outputs and a 3.3V tolerant input? |
| 18:38.00 | RobotGuy | prpplague: The logical sites to go to are the Edimax and Ralink sites. No mention of any firmware for RT73 there. |
| 18:38.11 | prpplague | RobotGuy: no, it won't be on those |
| 18:38.43 | ds2 | RobotGuy: look here - |

| 18:39.42 | prpplague | ds2: yea there is such a thing, but i don't know the part number of the top of my head |
| 18:39.55 | prpplague | ds2: t0mw would know |
| 18:40.03 | ds2 | prpplague: any chance you know a mfg of such? I can search for it that way |
| 18:40.50 | prpplague | ds2: any of the 74 series manufacturers should have it |
| 18:41.06 | ds2 | 'k thanks I'll start there |
| 18:41.43 | prpplague | ds2: mouser and digikey both have good matrix searchs for narrowing down what you need |
| 18:42.26 | ds2 | mouser overwelms with search results; I'll try digikey later - main thing I wanted to know is if it exists |
| 18:43.19 | ds2 | Yippeee found one... fair child |
| 18:43.30 | ds2 | now to see if I can actually get it ;) |
| 18:45.07 | RobotGuy | ds2: It isn't there |
| 18:45.32 | ds2 | RobotGuy:you just need RT73.bin? |
| 18:45.41 | RobotGuy | ds2: Yeah, I guess so. |
| 18:45.45 | ds2 | one sec |
| 18:46.29 | ds2 | downing it first to make sure it works |
| 18:46.39 | RobotGuy | Where did you find it? |

| 19:31.09 | g1powermac | hmm, I know there's an LED controller out there that'll let you hookup multiple leds to it and be controlled via a microcontroller I guess over maybe a serial connection, does anyone know of a part number like that? |
| 19:32.02 | ds2 | thought maxim had something like that |
| 19:32.30 | g1powermac | if its maxim, that'd be awesome |
| 19:32.36 | g1powermac | goes to check them out |
| 19:35.13 | g1powermac | hmm, I see high brightness LED controllers, not exactly what I'm looking for, though I must bookmark that for another project. . . |
| 19:37.00 | g1powermac | needs a controller that can individually control many leds |
| 19:39.28 | g1powermac | doh, they do have something that'll work |
| 19:39.34 | g1powermac | the MAX6958 |
| 19:43.02 | g1powermac | hrm, though not really |
| 19:49.19 | RobotGuy | g1powermac: TLC5940 |
| 19:49.40 | RobotGuy | There are also a few Maxim parts. |
| 19:51.24 | g1powermac | ahh, nice |
| 19:52.59 | g1powermac | now I just need a huge perf board and a boatload of leds. . . |
| 19:58.25 | g1powermac | meh, the only thing with the TLC5940 is its serial connection. . .can't just hook it up to a UART |
| 19:58.48 | chouimat|work | g1powermac: I did a nice test : 10 minutes to compile qt4.4.0 :) |

| 20:12.15 | RobotGuy | Wow, there are five WiFi cells near me. |
| 20:14.04 | RobotGuy | g1powermac: Picky picky. :P |
| 20:14.27 | g1powermac | RobotGuy, hehe |
| 20:14.46 | g1powermac | though really this type of serial connection seems to be common with this kind of device |
| 20:17.04 | g1powermac | huh, surprising, I figured at least one person on ebay would be selling giant perf boards |
| 20:17.37 | g1powermac | though there is this nice stackable one. . . |
| 20:18.12 | MothaWork | g1powermac: the USART on most microcontrollers can operate in a synchronous mode, though sometimes only half duplex |

| 20:18.30 | g1powermac | MothaWork, catch phrase is 'most' :-) |
| 20:18.36 | MothaWork | well, true |
| 20:18.41 | MothaWork | but all the 8051s and AVRs I've seen can |
| 20:19.01 | MothaWork | the original Intel 8051 USART was capable of it, I think |
| 20:19.05 | g1powermac | I'll have to look at the uart in the ds89c450 some more |
| 20:19.46 | MothaWork | that sounds like an 8051 |
| 20:19.57 | MothaWork | though if it's the Dallas one, they change some stuff |
| 20:20.04 | g1powermac | it is |
| 20:20.14 | g1powermac | yea, its dallas's 8051 |
| 20:20.58 | g1powermac | hmm, this is a pretty big perf board: http://cgi.ebay.com/PKG5-CIRCUIT-PANEL-PCB-DIY-Prototype-Board-130X250-C5_W0QQitemZ290245846871QQihZ019QQcategoryZ7285QQssPageNameZWDVWQQrdZ1QQcmdZViewItem |
| 20:24.16 | g1powermac | I get five of them too. . . |
| 20:30.54 | g1powermac | MothaWork, according to the datasheet, the serial ports are 100% compatible with the 80C52 standard |
| 20:31.20 | kergoth`work | who's the current busybox maintainer? |
| 20:31.28 | kergoth`work | 's so out of the loop nowadays |
| 20:32.07 | g1powermac | digs a little further into the ds89c450's user guide |
| 20:32.52 | MothaWork | g1powermac: ok. Wasn't sure if they changed the USARTs or not |
| 20:32.55 | g1powermac | MothaWork, heh, yea, you're right |
| 20:32.59 | MothaWork | I know the CPU core is optimized |
| 20:33.20 | g1powermac | Mode 0 does the synchronous serial half duplex stuff |
| 20:33.24 | MothaWork | there you go |
| 20:33.31 | g1powermac | and I never noticed that before, doh |
| 20:33.48 | g1powermac | that would've saved me some headaches with other projects ;-) |
| 20:33.50 | MothaWork | well, it is a USART, not a UART |
| 20:34.11 | g1powermac | tell that to the stupid tech writers who keep calling it a UART in the dallas paperwork. . . |
| 20:34.38 | MothaWork | I think the Intel datasheet used the term USART |
| 20:34.40 | g1powermac | its always referred to as "UART" not "USART" |
| 20:34.42 | MothaWork | I know Atmel's datasheets all do |
| 20:34.54 | g1powermac | bad dallas tech writers ;-) |
| 20:34.56 | kergoth`work | Denys Vlasenko ... whoever that is |
| 20:34.57 | MothaWork | at least I think they do on 8051. They do on AVR, but then it's a different peripheral |
| 20:35.05 | MothaWork | I never liked the Dallas/Maxim datasheets |
| 20:35.16 | g1powermac | yea, they have issues |
| 20:35.42 | g1powermac | well, that worked out wonderfully |
| 20:35.50 | MothaWork | they have some really neat parts, though |
| 20:35.52 | g1powermac | now onto buying the massive perf boards |
| 20:36.00 | MothaWork | I'm just put off by the issues some people have sourcing them |
| 20:36.20 | g1powermac | is going to build an LED sign of the logo for "This Old Gadget" |
| 20:36.38 | g1powermac | with full control over the brightness of the LEDs to give it cool effects :-) |
| 20:40.26 | MothaWork | individual control? |
| 20:40.29 | MothaWork | that's a lot of PWM outputs |
| 20:40.53 | MothaWork | I'd probably look into doing some sort of external CPLD based thing and hook it up via SPI, since I don't know of a micro with THAT many PWM outputs |
| 20:41.01 | MothaWork | I guess you could PWM in software, but that's a lot of CPU time |
| 20:46.45 | g1powermac | MothaWork, thats why I'm using a batch of TLC5940's |
| 20:48.59 | MothaWork | even still, that's only 16 channels |
| 20:49.39 | g1powermac | well, with five TLC5940's, I'll have control over 80 leds |
| 20:49.54 | MothaWork | heck, what you're talking about is big enough that I'd probably matrix it if I didn't need individual PWM control, which is tough with a matrix |
| 20:50.23 | MothaWork | that said, you can toggle IOs pretty fast on modern micros; a PWM'd matrix might be doable |
| 20:52.27 | g1powermac | hmm |
| 20:54.24 | MothaWork | basically run the rows as regular IOs and PWM the columns (or vice versa) at a rate several times higher than the row rate |
| 20:55.01 | MothaWork | should be able to get at least 5-6 bits of intensity out of that |
| 20:55.14 | g1powermac | hmm |
| 20:56.09 | g1powermac | for me to do that though I'd have to get something that would do the power sinking, as I know the ds89c450 won't be able to handle that kind of power |
| 20:56.29 | MothaWork | many micros can sink at least 10mA |
| 20:56.48 | MothaWork | now it'll be kinda dim if you do that (depends on how many rows), but it's doable |
| 20:57.04 | MothaWork | you could buffer each side with transistors |
| 21:00.41 | g1powermac | meh, I think the TLC5940's would be easier, especially if I forget individual control and do more regional control over different sections |
| 21:01.27 | RobotGuy | Is there a secret to opening up a LinkSys gateway? |
| 21:01.58 | g1powermac | opening anything like that is always a challenge |
| 21:02.14 | g1powermac | opening the zipit2 the first time was, well, interesting. . . |
| 21:06.49 | RobotGuy | I'd like to not damage the case if possible. |
| 21:07.41 | MothaWork | those types of cheap consumer electronics are usually laden with plastic clips |
| 21:07.47 | MothaWork | or even glue! |
| 21:07.48 | g1powermac | yup |
| 21:07.54 | MothaWork | they are sometimes flat out impossible to open without damaging them |
| 21:08.02 | g1powermac | having long finger nails, especially thumbnail really helps |
| 21:08.07 | MothaWork | especially if you don't know where the clips are |
| 21:08.47 | g1powermac | fingernails are hard enough to get in between the plastic layers to unhook the clips, yet soft enough to not damage anything |
| 21:08.59 | RobotGuy | Hmmm, well this unit doesn't work as it is (bricked, I am assuming), and all I really want is the board if I can recover it somehow. Warantee is already voided. |
| 21:21.05 | RobotGuy | I'm thinking this case will not survive.. |
