| 00:55.09 | joe_bleau | 12.5mF @ 370V ?! Sounds like a *big* cap. How large is it, physically? |
| 01:16.15 | sunrunner20 | huge |
| 01:16.28 | sunrunner20 | i think she said 2.5" diamater |
| 01:20.01 | sunrunner20 | i need to build a large cap charg circuit |
| 01:20.07 | sunrunner20 | get get a group of flash tubes |
| 01:20.36 | sunrunner20 | multi use flash bang |
| 01:20.38 | sunrunner20 | w/o the bang |
| 01:20.59 | sunrunner20 | use it in the locker room when dumb fucks decide to turn the lights out and stand in the entry way |
| 01:21.14 | sunrunner20 | i need to get a small digi cam corder |
| 01:21.29 | sunrunner20 | set it up |
| 01:21.32 | sunrunner20 | somewhere hidden |
| 01:21.43 | sunrunner20 | record what happens when they do it |
| 01:21.46 | sunrunner20 | and i set it off |

| 02:27.20 | jbevren | mili is .001 |
| 02:29.34 | GPSFan | jbevren: are you going to write up your scanner server for the wiki? I have an adaptec card and an hp 4c scanner, and amthinking it might be a good thing to do with one of my DHT's.. |
| 02:30.41 | GPSFan | btw 12.5 millifarads @ 370Vdc is a serious cap..., can easily kill you.. |
| 02:36.03 | jbevren | GPSFan: I will eventually. Its pretty straightforward, since I used debian linux to do it |
| 02:36.17 | jbevren | did you catch the pictures of my project? |
| 02:37.21 | sunrunner20 | GPSFan: i know |
| 02:37.56 | jbevren | GPSFan: that said, I want to work on making a custom microwave controller heh |
| 02:38.11 | GPSFan | jbevren: the DHT in a scsi box, yeah, I'm looking through all my junk looking for something appropriate. |
| 02:39.00 | jbevren | GPSFan: the big challenge is getting /dev/sg0 writable by saned |
| 02:39.08 | jbevren | that's where dpkg-statoverride comes in :) |
| 02:39.28 | jbevren | dpkg-statoverride --add --update 0770 root saned /dev/sg0 |
| 02:39.30 | jbevren | :-D |
| 02:39.41 | GPSFan | sunrunner20: when I forst saw your post I thought you had made a typo and menat uF, but at 2.5" dia I relaised that yo did relaly mean mF.... |
| 02:39.55 | GPSFan | crap , can't type this evening... |
| 02:40.05 | sunrunner20 | lol |
| 02:40.31 | GPSFan | jbevren: that's the kind of info that's so critical to others reproducing your project. |
| 02:40.39 | jbevren | nodnod |
| 02:40.48 | sunrunner20 | i'll need to make a discharge circuit |
| 02:40.59 | GPSFan | I would just have done chmod 777 /dev/sg0 |
| 02:41.10 | jbevren | that would work |
| 02:41.14 | jbevren | and everyone seems to be using that |
| 02:41.20 | jbevren | I'm just more security-paranoid :) |
| 02:41.42 | jbevren | realistically, I should have added a 'sg' group for the scsi generic class device access |
| 02:41.48 | jbevren | and set saned in that group :) |
| 02:42.02 | jbevren | debian's saned build has its own uid heh |
| 02:42.05 | GPSFan | yeah, but your way is more in keeping in line with the spirit of dpkg |
| 02:42.17 | jbevren | right |
| 02:42.26 | jbevren | cause an update on /dev would reset the permissions |
| 02:42.45 | jbevren | it also keeps the dpkg-aware security checks from complaining |
| 02:42.58 | GPSFan | right.. |
| 02:43.01 | jbevren | you could dpkg-statoverride 777 root root the device heh |
| 02:43.12 | jbevren | but anyway |
| 02:43.24 | jbevren | There's a couple things I want to do first |
| 02:43.49 | GPSFan | btw, I gor the atyfb driver running on the DHT. so now there are 2 cards that work. |
| 02:43.52 | jbevren | run xsane locally on the device (remote-X11 to your terminal via ssh forwarding) in case you dont have or cant install sane |
| 02:43.57 | jbevren | and a webserver for fetching scans |
| 02:44.06 | jbevren | oh? |
| 02:44.07 | jbevren | aty just crashed for me |
| 02:44.13 | jbevren | did you need any tricks? |
| 02:44.20 | sunrunner20 | LOL |
| 02:44.28 | sunrunner20 | this fractal is going to take an hour to render |
| 02:44.38 | sunrunner20 | 9000x9000px |
| 02:44.43 | jbevren | sunrunner20: My friend and I did a mandelbrot that took 35 days on an origin 2000 |
| 02:44.57 | jbevren | then we realized that mandelbrot only has so much color depth |
| 02:44.58 | jbevren | lol |
| 02:44.59 | sunrunner20 | origin 2000? |
| 02:45.21 | jbevren | http://www.jbevren.net/o2k/DSCN1592.JPG |
| 02:45.23 | jbevren | origin 2000 |
| 02:45.27 | jbevren | thats my friend, standing beside mine |
| 02:45.44 | GPSFan | yeah, the latest kernel 2.6.16-pre? removes the init that needs to be done to the hardware, was/is there in 2.6.15-5, and in addition there is a patch that needs to be done for non x86 hardware. |
| 02:45.52 | sunrunner20 | holy shit |
| 02:46.02 | sunrunner20 | how big was that mandelbrot? |
| 02:46.20 | jbevren | 1000x1000, 24 bit colorspace |
| 02:46.32 | jbevren | we found out to our disgust that there were only about 9 bits used |
| 02:46.38 | jbevren | or something like that :) |
| 02:46.45 | jbevren | we should have gone huge with an 8bit colorspace |
| 02:47.15 | jbevren | anyway, he intelligently spit the work into 14 batches (I have 14 live cpu's) |
| 02:47.22 | jbevren | and it ran for a month heh |
| 02:47.31 | GPSFan | jbevren: wow... |
| 02:47.34 | sunrunner20 | whats it look like? |
| 02:47.38 | sunrunner20 | besides |
| 02:47.42 | jbevren | like a 1000x1000 mandelbrot :( |
| 02:47.43 | jbevren | heh |
| 02:47.51 | sunrunner20 | dude |
| 02:47.59 | sunrunner20 | there are litterally thousands upon thousands of combonations |
| 02:48.04 | jbevren | mandelbrot, the math itself, doensn't use that much colorspace |
| 02:48.15 | jbevren | we realized the depth it didnt use and never bothered putting the data into an image |
| 02:48.24 | sunrunner20 | -_- |
| 02:48.43 | jbevren | 5 mins.. |
| 02:49.01 | jbevren | I like having my friend stand beside the thing, he's only 5'5" |
| 02:49.05 | jbevren | so it looks huge heh |
| 02:51.21 | jbevren | sunrunner20: sadly, I originally suggested an 8bit depth and a huge imagesize |
| 02:52.11 | sunrunner20 | http://sunrunner20.brainspore.net/files/resourcesmodule/@random42b891e9445d5/1141613506_SterlingFractal.zip |
| 02:52.18 | sunrunner20 | good program |
| 02:52.26 | jbevren | I used to use xfractint |
| 02:52.35 | sunrunner20 | thats for windows |
| 02:52.40 | jbevren | how parallelizable is your application? |
| 02:52.44 | jbevren | xfractint is for windows? |
| 02:52.49 | sunrunner20 | no |
| 02:52.54 | sunrunner20 | the program i linked to |
| 02:52.55 | sunrunner20 | is windows |
| 02:52.56 | jbevren | oh |
| 02:53.03 | sunrunner20 | and from what i can tell |
| 02:53.06 | sunrunner20 | its purely serial |
| 02:53.06 | jbevren | windows doesnt run on origin 2000 hardware |
| 02:53.10 | sunrunner20 | but |
| 02:53.13 | jbevren | :-D |
| 02:53.31 | jbevren | NT4 did have a MIPS port |
| 02:53.39 | jbevren | but it never ran on SGI |
| 02:53.49 | sunrunner20 | 9000x9000 8bit pretty damn complacated fractal |
| 02:53.57 | sunrunner20 | i estimate takes an hour |
| 02:54.32 | jbevren | yeah well my amd64 can probably outdo half of my origin |
| 02:54.34 | jbevren | heh |
| 02:54.39 | jbevren | so that's not surprising |
| 02:55.00 | sunrunner20 | try that progry |
| 02:55.06 | sunrunner20 | wine should run it no problem |
| 02:55.12 | jbevren | no. :) |
| 02:55.16 | jbevren | I would actually, |
| 02:55.21 | jbevren | but I'm not interested in fractals atm :) |
| 02:55.34 | jbevren | queue position: 13 |
| 02:55.40 | jbevren | I feel like I'm waiting for MS tech support :) |
| 02:55.43 | jbevren | I started at 400 |
| 02:56.28 | jbevren | GPSFan: I was explaining to my brother why I would want linux controlling my microwave heh |
| 02:56.37 | jbevren | what if I want to see the radar |
| 02:56.43 | jbevren | weather radar that is |
| 02:56.53 | jbevren | or maybe communicate with the controller in the stove |
| 02:57.10 | jbevren | or have it IM me when it's finished (think cellphone IM client) |
| 02:57.22 | jbevren | hehe |
| 02:57.32 | jbevren | people arent alwasy within earshot of their kitchen |
| 02:57.50 | sunrunner20 | http://sunrunner20.brainspore.net/files/imagegallerymodule/@random429e79e399d07/gallery8/b_W_one.jpg |
| 02:58.14 | GPSFan | jbevren: better linux than windoze.. |
| 02:58.22 | sunrunner20 | view it |
| 02:59.24 | jbevren | lots of chaos in that one |
| 03:00.00 | jbevren | symmentry's messy too |
| 03:00.13 | jbevren | sunrunner20: my favorite is the gingerbread man |
| 03:00.36 | jbevren | anyway |
| 03:00.40 | jbevren | I got through the queue |
| 03:00.41 | jbevren | bbl :P |
