| 00:12.28 | ds2 | raw panels in singles seems to go for $150-$300 range :( |
| 00:13.19 | MonMotha | yeah, the raw panels even in reasonable qty are about 2-3x the cost of the consumer electronic item containing them |
| 00:13.31 | MonMotha | the TV and PC monitor makers must have truly crazy volume |
| 00:13.53 | g1powermac_PB | why not buy just the consumer models and rip out the lcds? |
| 00:13.59 | ds2 | data |
| 00:14.00 | MonMotha | g1powermac_PB: lack of documentationm |
| 00:14.03 | g1powermac_PB | ahh |
| 00:14.18 | MonMotha | ds2: did you get a response back about those 7.8"ers |
| 00:14.20 | MonMotha | ? |
| 00:14.28 | ds2 | wonder if someone having to hold inventory has to do with it |
| 00:14.38 | ds2 | MonMotha: yep. shocked at the price |
| 00:14.43 | MonMotha | well, holding inventory is not cheap, especially not in this qty |
| 00:14.50 | MonMotha | ds2: high? what were you expecting? |
| 00:14.59 | MonMotha | I know the cost on those, but I can't tell you. |
| 00:15.36 | ds2 | MonMotha: I suspect these are prime new panels... I was expecting something sub $100 and I am willing to accept seconds/cosmetic defects |
| 00:16.27 | MonMotha | ds2: ah. These are prime and new. |
| 00:16.46 | MonMotha | I actually have the boxes they came in :) |
| 00:16.51 | MonMotha | or at least some of them |
| 00:16.51 | ds2 | MonMotha: for what I want, prime and new are overkill |
| 00:18.20 | ds2 | it is like putting in a rolls royce engine into a Yugo :( |

| 00:50.55 | Mirell | MIB II quote.. |
| 00:51.02 | Mirell | Seemed vaguely appropiate. |
| 00:51.31 | ds2 | Got to remember Movie... not NMS when someone talks about MIB |
| 00:51.51 | Mirell | Hee |
| 01:19.58 | MonMotha | ds2: nothing wrong with a rolls royce engine in a Yugo |
| 01:20.03 | MonMotha | overkill, certainly, but it'll work :) |
| 01:21.59 | ds2 | the problem is when you are trying to sell a fleet of yugos fitted this way and not loose your shirt doing it |
| 01:55.29 | solar | about how many amps at 12VDC would it take to kill or seriously hurt me? (for safety reasons) |
| 01:58.16 | ds2 | depends on your skin resistance |
| 02:00.31 | solar | i have a 75AH sitting next to my bed. I fell out out bed one night and landed hit my knee on it. So I'm thinking the chances of me getting shocked are pretty good. |
| 02:01.04 | solar | trying to figure about how many is too many for indoor use. |
| 02:02.31 | ds2 | I think if you have a cut so there is a blood path, the values are much lower |
| 02:02.39 | ds2 | wasn't the numbers like 1-2mA can stop a heart? |
| 02:07.14 | solar | oh I'm #$% already then. Sorta want to shoot for around 250AH |
| 02:08.17 | solar | well probably 300 |
| 02:08.58 | ds2 | I just don't worry about such things |

| 02:12.02 | ds2 | directly across the heart |
| 02:12.05 | ds2 | look it up |
| 02:12.28 | ZeZu | oh i believe you just seems like a low # |
| 02:12.36 | ZeZu | i guess its getting that 1-2mA there |
| 02:13.02 | ZeZu | I've gotten zapped a few (too many) times, doing dumb things |
| 02:13.35 | ZeZu | I know a car battery could get you pretty good, but requires some water in the mix :) |
| 02:14.09 | ZeZu | even a 600A cold cranking battery wont do much of anything against bare dry skin |
| 02:16.17 | ds2 | so it is a bit higher - |
| 02:16.19 | ds2 | http://www.cdc.gov/NASD/docs/d001801-d001900/d001824/d001824.html |
| 02:17.13 | ds2 | but I think those values are for the skin path, not say... from one bleeding wound to another |
| 02:19.27 | joe_bleau | Seems like the current capacity of a 12V battery hardly matters, as even 10mA is enough. |
| 02:19.35 | T0mW | heh, I seem to recall that chinese guy using a 12volt battery to torture Mel Gibson in Lethal Weapon? |
| 02:19.53 | joe_bleau | I'd be more worried about getting something metallic across the terminals. That could be very ugly with 100s of A behind it. |
| 02:20.00 | joe_bleau | Vaprorized metal, anyone? |
| 02:20.06 | T0mW | wet him down good then dragged the battery lead onto his chest. heh |
| 02:20.19 | ds2 | http://en.wikipedia.org/wiki/Electric_shock |
| 02:20.40 | ds2 | "a much lower current of less then 1 mA, (AC or DC) can cause fibrilliation..." |
| 02:21.22 | T0mW | I think I recall that 5..10ma of 500volts going from one hand to the other is enough to stop your heart. I always work with high voltage with, literally, one hand in my pocket. |
| 02:21.50 | ZeZu | hmm |
| 02:22.13 | T0mW | it is not so bad if the electricity travels down your arm to a leg. |
| 02:22.23 | ZeZu | i touch car batteries all the time, the ammount of resistance its way too great to even get anything out of it |
| 02:22.33 | T0mW | correct |
| 02:22.46 | T0mW | typically, you will be a few megohms |
| 02:22.49 | ZeZu | I would certainly be concerned if i was wet and touching jumper cables very near each other however |
| 02:23.06 | ZeZu | but still not the same was how ds2 is talking about |
| 02:23.09 | T0mW | dry, that is a few megohms |
| 02:23.16 | ZeZu | i think med. paddles are way way up there |
| 02:23.41 | T0mW | not so high, remember, you only need a few millamps at several hundred volts. |
| 02:23.42 | ds2 | now repeat that during a tropical hurricane near the seaside |
| 02:23.55 | ds2 | soaking wet with sea water |
| 02:23.56 | ZeZu | The technique used an alternating current from a 300 or greater volt source delivered to the sides of the exposed heart by 'paddle' electrodes where each electrode was a flat or slightly concave metal plate of about 40 mm diameter. |
| 02:24.09 | ZeZu | o.O |
| 02:24.13 | T0mW | heh |
| 02:24.13 | ZeZu | haha |
| 02:24.15 | T0mW | lol |
| 02:24.31 | T0mW | I'll take a pass on that one. |
| 02:24.41 | joe_bleau | Wonder what the impedance of paddles on the exposed heart is. |
| 02:24.44 | T0mW | not my idea of everyday fun. |
| 02:25.12 | joe_bleau | Been a long time since I've been shocked. |
| 02:25.53 | ZeZu | i was dumb enough to try to cut through a live extension cord .. it was a good zip |
| 02:26.14 | ZeZu | went to a bigass sign too, if it was 220 then im just real lucky :) |
| 02:26.32 | T0mW | I've seen a guy get shocked with a Lincoln arc welder. If you know anything about electric welders, they are basically low voltage / high current transformers. They take 110v or 220v and drop it down to a few volts, that way you get the high amperage. |
| 02:26.43 | joe_bleau | Bet your cutters weren't so lucky. |
| 02:27.03 | ZeZu | yea i've got on in the garage |
| 02:27.04 | joe_bleau | What's the open circuit on that welder? Bet it's more like 60-80VAC. |
| 02:27.10 | ZeZu | old craftsman |
| 02:27.12 | T0mW | I saw tommy change the range on one of the older models with pullout plugs (a plugboard type) and it threw his a$$ about 12 feet. |
| 02:27.15 | joe_bleau | HF on a TIG welder can bite too. |
| 02:27.44 | T0mW | he leaned on the welder with one hand, then pulled the plug with the other, pow! |
| 02:28.12 | T0mW | he lived |
| 02:28.30 | T0mW | he was also 20 years old at the time... |
| 02:29.10 | T0mW | joe_bleau: hard to tell, I only know that they are stepdown transformers. |
| 02:29.44 | joe_bleau | I thought they were designed to be magnetically lossy, to act a bit like a current source. |
| 02:29.50 | T0mW | correct |
| 02:29.57 | joe_bleau | More like a MOT than a standard stepdown xformer. |
| 02:30.02 | T0mW | but, multi-tap |
| 02:30.26 | T0mW | we had one that you cranked to get down to your amperage. |
| 02:30.54 | T0mW | before electronics, heh |
| 02:31.17 | T0mW | s/electronics/electronic controls/ |
| 02:31.49 | T0mW | joe_bleau: how hard is TIG to use? |
| 02:31.57 | T0mW | I've only done arc |
| 02:32.08 | T0mW | and some gas |
| 02:32.17 | joe_bleau | More like gas welding. I can drag a bead, but I'm not really qualified. |
| 02:32.24 | T0mW | nod |
| 02:32.32 | T0mW | I see they have cheap setups now. |
| 02:32.36 | joe_bleau | Grainger shows OCV on their site: http://www.grainger.com/Grainger/categories/power-tools-and-metalworking/electric/arc-welders |
| 02:33.29 | T0mW | ah |
| 02:34.21 | T0mW | thinks he'll pay someone to weld rather than buy a welder. |
| 02:35.54 | MonMotha | joe_bleau: did you get the opportunity to look at those LCD modules I found? Some of them looked like they could work for your project at work. |
| 02:36.02 | ZeZu | i've got something similar to : http://www.sears.com/shc/s/p_10153_12605_00920505000P |
| 02:36.46 | joe_bleau | No, which modules? (I think the lcd project is gonna be put on hold, as it's very unlikely we can hit their new deadline.) |
| 02:38.02 | T0mW | ZeZu: so, what does one do when they own something like that? Build cars? |
| 02:38.41 | ZeZu | idk about building them, but repair frames and other random things that involve welding :) |
| 02:40.38 | T0mW | heh, enter into demolition derbies. |
| 02:42.51 | ZeZu | sounds fun |
| 02:44.55 | solar | anybody ever seen a sdcard go into read-only mode and not want to come back out? yes the tab is pushed fwd |
| 02:46.03 | T0mW | solar: cheap-o brand-x card? |
| 02:47.32 | solar | actually. Seems maybe local computer. Just tested with another sdcard |
| 02:47.37 | solar | and same thing. |
| 02:47.59 | solar | one kingston and another I use fine in other devices. |
| 02:48.24 | MonMotha | joe_bleau: oh, you must have missed my messages. May I PM them to you again? |
| 02:49.15 | T0mW | I would suspect noise on the power supply lines to that card. IF you have ruled out a possible command format problem. I assume that you are just doing run-of-the-mill read / writes when it does this? Nothing fancy? |
| 02:49.20 | MonMotha | though I guess if that project is on-hold, then it doesn't matter as much |
| 02:49.51 | solar | T0mW: really basic. Like just trying to mount or fdisk the card |
| 02:49.54 | MonMotha | solar: the tab is entirely just a mechanical thing. It's up to software to enforce it. |
| 02:50.11 | solar | seems more like the kernel is confused |
| 02:50.22 | T0mW | solar, I have not had that happen with SD. |
| 02:50.42 | solar | me either till last night |
| 02:51.26 | T0mW | I've primarily used SD cards with proprietary embedded systems, not a lot of exeperiece with using them with linux though. |
| 02:53.20 | MonMotha | I've only ever used SD cards in Linux from a USB reader, and those just show up as USB mass storage |
| 02:54.08 | solar | yeah here also. |
| 02:54.15 | solar | I even managed to flash it 1 time. that is the kicker |
| 02:54.49 | solar | got a guy on another channel saying he heard something about the kernel getting a bit wrong. But only for disks |
| 02:56.23 | ZeZu | are you booting from it ? |
| 02:57.17 | solar | No. At this point I just need to edit my inittab so I can get a console |
| 02:57.53 | solar | oh but yes. I will be booting from it. |
| 02:57.54 | ZeZu | hmm i would say if it mounted it RO then never unmounted and remounted RW it could explain it |
| 02:58.12 | ZeZu | but you should be able to tell, or if you have an entry in fstab for it |
| 02:58.43 | T0mW | I've two test systems (S3C2410) that boot from SD cards, nothing unusual has happened with relation to the SD cards. |
| 02:59.18 | T0mW | oh, then there is the zipits. |
| 02:59.28 | solar | fstab in gentoo is all manual. This would be just a simple. mount /dev/sda2 /mnt/beagle/2 .. |
| 02:59.36 | ZeZu | i've had something similar happen with a hard drive once, but that was the case , the kernel didn't want to unmount |
| 02:59.51 | *** mode/#edev [+o Mirell] by ChanServ |
| 02:59.52 | ZeZu | solar, sure but it could specify ro |
| 02:59.59 | solar | probably kern. I'll try a few revs back when I was last playing with the 8050. |
| 03:00.12 | solar | oh ZeZu. yeah I checked that to make sure it's off. |
| 03:00.36 | solar | and note I did manage upon first boot of the laptop. I mounted it fine and put a new image on it. |
| 03:00.43 | ZeZu | i figured, was just throwing out my .02.. it took me a while to figure that out, but my experience with linux then was null |
| 03:00.59 | solar | but I did not umount it properly before pulling the power |
| 03:01.25 | ZeZu | fsck maybe, but it would run it automatically normally too |
| 03:01.36 | solar | then umounted after the fact etc. So running a new mke2fs -T small /dev/sda2 would be fine. If it let me do it. |
| 03:02.05 | solar | fsck only wants to work in this case with the -n flag (for read-only checking) |
| 03:02.13 | joe_bleau | MonMotha: sure, email, pm, whatever, whenever. |
| 03:02.15 | solar | shrug. It's probably got to be a kern bug. |

| 04:46.33 | MonMotha | I've had some luck finding docs for random LCDs pulled from consumer electronics |
| 04:46.43 | MonMotha | seem to "hit" ~10-15% of the time |
| 04:47.00 | MonMotha | I found docs for the one that got ripped out of a DVD player, for example |
| 04:47.43 | ds2 | with the prices I am seeing for LCDs, I can buy a eeePC |
| 04:48.06 | ds2 | part off the MB, SSD, etc to sell AND come out ahead |
| 04:48.08 | MonMotha | yeah, it's kinda scary |
| 04:48.25 | MonMotha | those consumer items just have crazy insane ludicrous volume |
| 04:48.37 | MonMotha | they can sometimes quote their volumes in millions of units |
| 04:48.45 | ds2 | there aren't THAT many eeePCs around |
| 04:49.05 | MonMotha | I wouldn't be surprised if they use the parts in other things |
| 04:49.08 | MonMotha | Asus makes a lot of stuff |
| 04:49.19 | ds2 | good point |
| 04:49.42 | ds2 | if they really have that much volume, there must be an outlet somewhere for the imperfect panels |
| 04:51.12 | MonMotha | 1.7M units shipped as of 3Q 08 |
| 04:53.43 | ds2 | Hmmm |
| 04:54.06 | ds2 | so a 10-20% reject rate for imperfect panels should equal a lot of them floating around somewhere |
| 05:07.04 | MonMotha | dunno |
| 05:07.10 | MonMotha | maybe they just immediately scrap them |
