nmz787yes10:01
nmz787that is another episode10:01
chidonmz787: I'd let you hire me to do the drawing10:08
chidonmz787: also, how is the mouse situation developing?10:08
nmz787well, i was sad to let them go10:19
nmz787i did it near some bushes in a parking lot10:19
nmz787i probably should have taken them to a bigger park10:19
nmz787they were just scampering around under the bush after I had bleach sprayed the bin and thrown away the food and paper liner i had in the bin10:19
nmz787so i dunno, i feel like they're eaten or dead from not having a nest... but I could be underestimating instinct10:20
nmz787they were definitely deer mice though10:20
nmz787the ones who are known to be hanta virus reservoir10:20
nmz787that doesn't mean they had hanta10:21
nmz787but...10:21
nmz787seems the only real treatment for hanta is breathing pure oxygen since its a respiratory thing10:21
nmz787it's also RNA based, so I guess I could huff NaOH fumes or something to clean my lungs of RNA10:21
brownieshow many moose did you have?10:21

nmz7878.5ms gtg10:24
nmz787but i dunno how much that matters10:24
nmz787isn't that like 117hz10:25

archels8 ms is not ultra fast10:37
ThomasEgi.. lcd panels have been "fast enough" for like a decade now.10:43
ThomasEgii wonder why people still use those reaction times and stuff.10:44
ThomasEgiit's just marketing.10:44
ThomasEgiif you want to go for something. color reproduction might be an parameter that's worth the discussion.10:44
ThomasEgispeed is only really of interest when you'r using 3d shutter glasses.10:44

archelsFast enough for what? There are still plenty of bad panels, of which the slow response time can easily be discerned by just looking.11:01
archelsBut I agree on the the colour reproduction.11:01
ThomasEgiarchels, the last panel i know with slow respones are is the one in my now 12 year old backup-laptop.11:05
-!- Lucas__ [6c115747@gateway/web/freenode/ip.108.17.87.71] has joined ##hplusroadmap11:05
ThomasEgiwith the introduction of the active tft matrix , that problem was pretty much fixed. especially for tv as it doesnt require quite as fast response as gaming11:06
ThomasEgicolor on the other hand.. there are still so many screens out there with yucky color reproduction..11:07
ThomasEgionce you have had hands on somethig like a the iiyama displays used for traide fairs and exhibitions.. you'll see the world with different eyes11:08

nmz787but still isn't most video outputted by windows or debian 60 or 90hz11:38
nmz787yeah i dunno there are a lot of screens that are 2ms, but i guess that's just for gamers11:39
nmz787i code mainly and watch tv shows or movies, so 117 hz (8.5ms) seems more than sufficient11:39
nmz787i don't like those new 120hz motion interpolation features some tvs have anyway11:39
nmz787color is important though :{11:39

TheEmpathit is possible to use a radio frequency transmitter to extract hydrogen gas from saltwater, then ignite the gas to reach 1500 C. http://www.youtube.com/watch?v=JiKa4nOkHLw11:45

uf6667TheEmpath: I think a faster way is to create NaAlH411:55
uf6667and control H2 production using water drip11:55
uf6667the production is fairly fast at room temp, exothermic reaction11:55

jrayhawkI actually do sub-millisecond-accuracy testing for this, and no, LCD timing issues are not a problem of the past.12:21
nmz787jrayhawk: what's the effect?12:21
jrayhawkmultiple frames of delay, sometimes variable12:22
jrayhawkthis matters deeply to gamers and people doing screen-based timing tests.12:22
nmz787ahh12:23
nmz787so even though grey to grey is 8 ish ms (117hz max refresh rate) ,there's some wobble12:24
nmz787so is that monitor dependent or graphics or CPU/scheduler?12:24
jrayhawk'gtg' does not measure input latency.12:25
jrayhawkBasically every latency number advertisers use is useless.12:25
jrayhawkTN panels change color plenty fast, the problems are all in the lazily implemented firmware/controller logic.12:26
jrayhawkthings like color correction, scaling, firmware settings UI display, etc12:28
jrayhawkI think the next monitor I get will be a Yamasaki Catleap 2B Extreme12:28
jrayhawkwhich blessedly has none of those things12:28
jrayhawkspeaking of which, TN displays suck for viewing angle and color accuracy; small IPS panels are getting fairly affordable.12:29
ybitanyone know of other examples of skynet, a "fictional, self-aware artificial intelligence system " in terminator12:31

nmz787there are some decent looking 40 inchers on craigslist, samsung and sony, but they're 2-4 or 5 years old12:47
nmz787so i dunno if its wise to get better brands, older, or the latest chinese clone12:47
jrayhawkSonys theoretically have UPnP MediaServer-friendly firmware, though in practice it appears to be flaky as hell.12:49
nmz787so i was asking this question in another channel, then pasted jrayhawk's comments and some dude got all pissed at me12:51
nmz787saying i should have used pastebin12:51
@kanzureyou probably should have used pastebin, yes12:51
nmz787you post news articles sometimes though12:51
nmz787why dont you put that into pastebin?12:52
@kanzurebecause you guys let me get away with it12:52
nmz787great12:53
nmz787you've allowed my neural network to be borked12:53
@kanzuremost of the time i don't use pastebin for things in here because i can just upload a file to my server12:56

nmz787like oh, yeah, your teachers forgot to tell you 2 million equals one thousand14:25
jrayhawkcontrast ratios are also worthless numbers14:26
jrayhawkmost likely one of those is dynamic contrast ratio and one of them is real.14:27
jrayhawkwell, "real" insofar as any number with no published methodology can be14:27
jrayhawkOne of the tricks firmware can do is dynamically adjust the backlight for very dark scenes.14:28

@kanzureis there an open source eye tracking framework thing? maybe something using opencv?16:23
@kanzurei am also curious to know if there are eye tracking studies that study people looking at eye tracking studies.16:24
nmz787heh16:24
ThomasEgikanzure, shouldnt be too hard to find. it's just tracking a circle after all.16:25
nmz787i think getting the info out is a bit more work tho16:26
nmz787setting up all the initial shit16:26
chris_99don't they normally use IR though16:26
@kanzurehttp://nashruddin.com/eyetracking-track-user-eye.html16:28
ThomasEgichris_99, not sure. but removing the IR filter from a webcam takes me bout 2 minutes. and one minute is finding the right screwdriver16:30
nmz787yeah but then you need a vis filter on that16:30
chris_99you need an IR torchy thing to, as it picks up the IR reflection too16:30
chris_99from the pupil16:30
ThomasEgisome IR led's and some developed analog photo film (fully exposed).16:33
ThomasEgithat gives you a nice black piece of film material. which filters out most visible light. but its rather transparent to IR16:34
ThomasEgii did such mods in the past. pretty funny as it several kinds of fabric are almost ransparent in the IR range.16:34

nmz787none of those folks called me back in regards to a portland lab16:53
@kanzurethose costs add up quick16:53
nmz787yeah but a 3d scan only takes maybe 30 mins16:54

Malusethhave you guys seen any cheap 3d scanners?18:12
@kanzureyes.18:12
Maluseththey are like 3k at least right?18:12
@kanzureno.18:12
@kanzurestereoscopic webcams don't cost that much.18:13
Maluseththat's another way of bypassing the dilemma18:13
Maluseththanks18:13
Malusethbut is there an assembled one perhaps18:13
@kanzurean assembled webcam?18:13
Malusethi mean...18:13
Malusethfully portable, standalone thing18:13
@kanzureyes, a webcam.18:14
Malusethhow many webcams would i need in order to scan a person?18:14
Malusethlol18:14
ThomasEgistereoscopic webcams have a horrible 3d resolution :D18:14
ThomasEgithere are ways to get 3d scans from a single camera using a line laser.18:14
Maluseththank you i will look into that18:14
ThomasEgihttp://www.david-laserscanner.com/18:15
ThomasEgithe basic version can be tried out for free.18:15
Malusethwow18:15
Malusethamazing. knowledge pays off always.18:16
ThomasEgitheir structured light scanner aint bad either.18:16
Malusethok i wish i had the money to buy something like that18:16
ThomasEgiseen it in real life.18:16
-!- _Sol_ [~Sol@c-174-57-58-11.hsd1.pa.comcast.net] has joined ##hplusroadmap18:16
Maluseth499 euro wuw18:16
ThomasEgiif you go for the laser-line scan. all you need is a reasonable webcam.18:16
ThomasEgiand a laser-line pointer. you can get them for 10 bucks on ebay18:16
Maluseththen software does the trick? wuw18:17
ThomasEgii'd recommend a green laser. as most cameras use bayer patterns which has twice as many green pixels as red or blue18:17
ThomasEgiyeah.18:17
ThomasEgias i said. their basic version is free.18:17
ThomasEgibut it isnt all too difficult to write a simple line-tracing software yourself.18:17
ThomasEgimade one as weekend project myself since that laserscanning thing doesnt run on linux.18:18
Malusethno i'm just learning right now complete beginner...18:18
Malusethbut vmware can run windows on linux right?18:18
nmz787i worked on a 3d scanner a while ago18:18
nmz787lookup point clouds18:18
ThomasEgiyeah. but i don't want to run windows.18:18
ThomasEgihttp://p3dp.com/doku.php?id=thomaseg1:start18:18
nmz787point cloud to 3d mesh18:18
ThomasEgithat was my result. after a weekend of tinkering18:18
Malusethnmz787 thanks.18:18
Malusethyou guys are geniuses18:19
ThomasEginmz787, cloudcompare?18:19
nmz787yeah it had two cameras, basic web cam types, can't remember if they had color bayer filters or if they were greyscale18:19
nmz787ThomasEgi: never heard of that18:19
Malusethsigh how can i get there18:19
@kanzurestop using windows18:20
ThomasEginmz787, pretty neat open source toolkit for working with pointclouds18:20
@kanzurestop using dreamweaver18:20
ThomasEgistop watching tv18:20
Malusethi think i'll just download the basic version, buy the stereoscopic webcam, and laser line pointers18:20
Maluseth:)18:20
nmz787but snapping pics was linked to stepping a stepper motor which had a platform attached18:20
ThomasEgiyou don't need a stereoscopi webcam18:20
Malusethyes yes. i'm doing that now18:20
ThomasEgia simple webcam will do.18:20
Malusethwasted enough time watching cartoons and playing games18:20
nmz787and each step was accompanied by several of the structured line black white alternating lines18:20
ThomasEgiMaluseth, in case you have a projector.. you could go with structured light scans.18:21
ThomasEgithey are amazing.18:21
Malusethso many ways. i dont have one, but i guess now i'm thinking it kind of works like chroma keying - green screen stuff18:21
ThomasEgibiggest problem i ran into at one point was. the distortion from my camera. you could actually see how the flat background got distroted in depth. didn't bother to fix that18:22
Malusethnvm i'll just use it and understand it18:22
Malusethif i can18:22
Malusethamazing info hopefully i can make something out of it18:22
Malusethhey 3d printer at 500 bucks18:22
Malusethsolidoodle or something18:22
nmz787you can develop a flatness profile with a checkerboard pattern and some software18:22
@kanzureyou can build a reprap for less than $50018:23
@kanzurefor someone with no money you sure do like to spend it18:23
Malusethi like to imagine, i can't spend anything18:23
nmz787basically you print a checkerboard pattern, or buy one mounted to hard wood/metal, then photograph it in various positions... i've literally had to dance around holding a 6 ft sq checkerboard befoire18:23
ThomasEginmz787, if you know your background is flat. you don't even need the checkerboard pattern.18:24
ThomasEgisimple hough transform of the triangulated data should get you the plane equation of the flat background18:24
nmz787then you run some (matlab was the one they had) code to figure it all out, and it spits out a nice matrix of numbers that define your optical distortion18:24
ThomasEgiand from there. you can calculate stuff backwards. creating a transform matrix18:24
nmz787yeah that's the fancy word for it18:24
nmz787i was usin a pico projector18:26
nmz787the one from digikey i think, the flagship one that TI endorses18:26
nmz787was decent res18:26
nmz787they were hoping to package it all into a product18:27
nmz787(they were an OEM for TI)18:27
ParahSailinMaluseth, did you take advantage of my free advice?18:27
MalusethNo parah... i didn't. I have a Grandma who needs taking care of.18:29
MalusethIf I was alone I may be able to.18:29
ParahSailinill have to be less generous to random strangers in the future18:30
Malusethbut thank you...18:30
nmz787here's what it looked like http://www.coolest-gadgets.com/20090202/real-view-3d-scanner/18:30

ThomasEgihehe. exists..18:32
ThomasEgibut costs18:32
Malusethhow much would it cost?18:33
ThomasEgimore than you want to pay18:33
@kanzureParahSailin: yeah i don't know what the point is here18:33
Malusethoh18:33
ThomasEgimilling is probably the most expensive part18:33
ThomasEgias it requires extensive mechanics and controll circuitry18:33
nmz787i never saw a mini foundry18:33
@kanzurenmz787: i'm pretty sure gingery had one18:33
ThomasEgicasting is rather cheap.18:33
nmz787seems wasteful18:34
nmz787i mean, seems more efficient to do bigger batches18:34
Maluseththere's limits on what you can make with filaments for the 3d printers right? i mean their density can't sustain itself?18:35
Malusethif in motion or something18:35
@kanzureyou seem to be all over the place18:35
@kanzurewhy are you jumping from a foundry to 3d printing?18:35
Malusethi am trying to piece these puzzles together18:35
@kanzurewhat puzzles18:35
Malusethi figure, after going plastic, you gotta go metal, and be able to learn programming languages to connect somesort of circuitry18:36

Malusethbut hard to convince a person who dont know how to use a computer sigh18:38
Malusethow18:38
@kanzuregive her an ipad. old people love ipads.18:38
Malusethit's good to know though18:39
Malusethkanzure: good idea18:39
ParahSailinkanzure, i recommend making here harder to find18:39
@kanzureParahSailin: i think you might be right18:39
ThomasEgimost of the time. traditional manufactoring of mechanical parts isn't that much of a bad idea.18:40
ThomasEgiunless they can be made from plastic18:40
ThomasEgior have very complex shape18:40
Malusethfor very complex shapes, plastic is a better choice because it's more flexible?18:40
Malusethok18:40
ParahSailini want to print my own nails to hammer studs together though18:41
ThomasEgiParahSailin, throw in enough money. and you can get everything printed.18:41
Malusethok i am going to research on everything bbl18:41
ParahSailinbeing facetious18:41
@kanzureParahSailin: why can't i get the high quality newbies?18:42
@kanzureit's not fair18:42
ParahSailinyour channel is not guessable18:42
ThomasEgihumans are strange. invited someone to share my lasagna with... the lady decided not to drop by and go to a party instead. might have hooked up there who knows. can't understand how someone could miss lasagna..18:42
