| kanzure | has anyone ever seen injection molding of a milling machine? | 09:38 |
| -!- willPow3r_ [n=will@cpe-66-75-6-181.san.res.rr.com] has quit [Remote closed the connection] | 10:07 | |
| katsmeow | kanzure, is injection molding the frame ofa milling machine any different than injection molding any large mass? | 10:08 |
| kanzure- | well, I'm talking about the whole thing I guess | 10:15 |
| kanzure- | more broadly my question should be of the nature of "insert here a request for your knowledge of weird ways to go about manufacturing other manufacturing unit processes" | 10:16 |
| katsmeow | i don't believe the accuracy of the injection molded device will make for an accurate milling machine,, unless you have an electronics compensation package to bolt onto it | 10:20 |
| kanzure- | http://en.wikipedia.org/wiki/PET_film_(biaxially_oriented) <- had to track down what 'scotch tape' adhesive really is (besides cellophane) | 10:22 |
| kanzure- | http://www.tattooartists.org/Gal3975_UV_Blacklight_Ink.asp | 10:35 |
| * kanzure- considers mixing sharpie with "UV blacklight tattoo" ink | 10:36 | |
| kanzure- | blacklightink.com | 10:37 |
| katsmeow | too kool | 10:39 |
| kanzure- | ah it's called BMX 1000 | 10:41 |
| kanzure- | or "spectral marking pigment" | 10:41 |
| kanzure- | oh wait, aren't UV sharpies advertized on TV all the time? | 10:42 |
| kanzure- | http://www.amazon.com/Sharpie-Invisible-Marking-Ink-Pen/dp/B000UH0MZG "1 new from $5.95" | 10:42 |
| katsmeow | and sharpies tend to stay put when sweating | 10:46 |
| kanzure- | well, what I'm trying to do now is find a UV toner cartridge for a laser printer | 10:51 |
| kanzure- | there's UV inks and diy formulas for such for inkjet printers, which might be ok I guess | 10:52 |
| kanzure- | anyway, the idea is to print out a pattern, expose a polymer to UV light but covered with the UV-inked-mask from a printer | 10:52 |
| katsmeow | so print the layers of a 3D object? | 10:59 |
| kanzure- | huh? | 11:00 |
| katsmeow | you run the printhead or laser lite over a pool of polymer, harden a thin pattern, drop the platform in the polymer pool .010 inch, print anothe layer, repeat | 11:03 |
| kanzure- | oh, I wasn't considering layered printing | 11:08 |
| kanzure- | but that's doable methinks. | 11:08 |
| kanzure- | http://synth-diy.blogspot.com/2008/10/making-of-uv-oven.html | 11:08 |
| kanzure- | hehe | 11:08 |
| katsmeow | been done, even | 11:08 |
| katsmeow | gee, no one heard of using flourescent lites? | 11:09 |
| kanzure- | I need a UV "glow in the dark" styrene acrylate copolymer, or polyester resin (not a UV-cure polyester resin), or styrene butadiene | 11:09 |
| kanzure- | yeah really. "I know! LEDs! yeah!" | 11:09 |
| -!- willPow3r [n=will@cpe-66-75-6-181.san.res.rr.com] has quit [Read error: 110 (Connection timed out)] | 11:10 | |
| kanzure- | hm, laser printers have a resolution of 8 to 16 micrometers (600 dots per inch) | 11:10 |
| kanzure- | don't know how useful that is here.. | 11:10 |
| * katsmeow mentions tpfq line etching | 11:11 | |
| kanzure- | ? | 11:13 |
| katsmeow | oh, for printing etch masks | 11:13 |
| katsmeow | laser the traces onto a pcb, the etchant removes where you didn't laser | 11:14 |
| kanzure- | but the laser seems to just do dots | 11:16 |
| kanzure- | and it's not useful to only have dots in making small patterned surfaces | 11:16 |
| katsmeow | umm, so don't turn the laser on/off for dots, keep it on | 11:17 |
| katsmeow | or step smaller | 11:17 |
| katsmeow | overlap the dots more | 11:17 |
| kanzure- | what's the minimum step size? | 11:27 |
| kanzure- | of a typical laser printer I guess | 11:28 |
| katsmeow | depends on the printer, i spose | 11:28 |
| -!- katsmeow is now known as katsmeow-afk | 11:34 | |
| -!- willPow3r [n=will@cpe-66-75-6-181.san.res.rr.com] has joined #hplusroadmap | 11:52 | |
| kanzure- | so the literature is saying that in general the max resolution is 200 micrometer width channels using laser printers | 12:01 |
| kanzure- | this is unfortunate, it would have been awesome to be able to print a 20 micrometer-max-resolution mask of UV-absorbent ink for use with the UV oven or something | 12:01 |
| kanzure- | the maskless UV lithography paper (pinhole UV led thingy apparatus w/ 50x objective lense) uses a syringe pump, a costly item for actuation of the substrate | 12:01 |
| kanzure- | piezos and tweets are used sometimes in amateur STM setups, but I'm not entirely sure how usable they are for actuation of this sort | 12:02 |
| kanzure- | a way to do this without requiring actuation would be great, but the printer resolution is just too big. :( | 12:02 |

| kanzure- | http://www.geocities.com/spm_stm/Disk_Scanner_Exp.html | 12:08 |
| kanzure- | hm, I don't understand how this could provide any sort of motion overall. I mean, I guess it could push something a bit if you left it underneath a piece of paper | 12:08 |
| kanzure- | but I don't know if that makes any sense :) | 12:08 |

| fenn | wow this is awesome http://www.myvu.com/DormRoom.aspx | 14:06 |
| bkero | heh | 14:08 |
| bkero | fenn: find me a pair with dvi | 14:08 |
| fenn | why bother when the best resolution you can get is 800x600 | 14:14 |
| fenn | 640x480 for <$1000 | 14:14 |
| bkero | ? | 14:20 |
| bkero | Yea, the budget for this entire thing is $450 | 14:20 |
| fenn | the cheapest HMD with 800x600 resolution is like $1300 used on ebay | 14:24 |
| fenn | myvu is a good choice | 14:24 |
| fenn | there is so much crap out there | 14:24 |
| * fenn playing around with xzoom for full screen 320x240 resolution | 14:25 | |
| -!- willPow3r [n=will@cpe-66-75-6-181.san.res.rr.com] has quit ["Leaving"] | 15:09 | |
| fenn | huh. myvu is based on microoptical | 15:57 |
| fenn | We realize this in LiFePO4 (ref. 6), a material with high lithium bulk mobility7, 8, by creating a fast ion-conducting surface phase through controlled off-stoichiometry. A rate capability equivalent to full battery discharge in 10–20 s can be achieved. | 17:04 |
| fenn | from http://www.nature.com/nature/journal/v458/n7235/abs/nature07853.html | 17:04 |
| bkero | fenn: I'm not concerned about the resolutoin as much as the input | 17:10 |
| bkero | I need digital input frmo the beagle | 17:10 |
| bkero | Right now I'm doing svideo->composite from the beagle | 17:10 |
| bkero | Which looks like a HUGE pile of shit | 17:10 |
| fenn | how so? | 17:11 |
| fenn | also i'd be interested in what happens if you don't connect the chroma signal, just luminance->RCA connector | 17:12 |
| bkero | composite signals don't do good at text | 17:54 |
| bkero | Or high resolutions | 17:54 |
| bkero | 640x480 being 'high' | 17:54 |
| fenn | do you think it'd be possible to hack the myvu circuitry? | 17:58 |
| fenn | (not that i have any idea what a HDMI signal looks like) | 17:58 |
| fenn | might be worth trying coax cable | 18:00 |
| bkero | I was thinking about doing it | 18:14 |
| bkero | Since the LCDs use LVDS | 18:14 |
| bkero | So I'd need HDMI->LVDS, which is possible, but the converter boxes are expensive, and big. | 18:15 |
| fenn | what's inside the glasses? some epoxy blob asic? | 18:16 |
| bkero | Pretty much | 18:17 |
| bkero | Most of the electronics are in a small box attached with a wire | 18:17 |

| kanzure | fenn: got it | 19:23 |
| kanzure | how about this? use the STM-piezo thingy and attach a mirror to it | 19:24 |
| kanzure | use it to pattern the UV led | 19:24 |
| kanzure | *to pattern with the UV led | 19:34 |
| fenn | ahahaa nice borg gear http://teleglasses.net/teleglass_t3-f_video1.html | 20:26 |
| fenn | better video http://www.youtube.com/watch?v=PMLmY3XJXEA&NR=1 | 20:28 |
| bkero | wtf | 20:29 |
| fenn | resolution sucks though - 320x240 | 20:29 |
| bkero | hugelame | 20:29 |
| fenn | not so sure | 20:30 |
| fenn | definitely cooler than 99% of the video glasses out there | 20:30 |
| bkero | The 320x240 automatically discuonts them though | 20:35 |
| bkero | *discounts | 20:35 |
| fenn | yeah, that's not good for anything | 20:37 |
| fenn | huh | 20:38 |
| fenn | Entertainment is not the main purpose of this innovation. They are targetting three fields of industry, beauty and medical care and the portable type digital microscope, the microscope and the video magnifier industry | 20:38 |
| fenn | scalar is a microscope manufacturer, primarily | 20:40 |
| bkero | beauty? | 20:56 |
| fenn | they have handheld video microscopes for looking at hair follicles or skin spots or something | 21:00 |

| kanzure | fenn: you might want to review the channel logs for previous links to myvu | 21:10 |
| kanzure | last time, I asked gene to document his random googlings and what he found on the wiki, but he didn't | 21:10 |
| kanzure | and there were a few times before where we found some fairly good links and such.. | 21:10 |
| bkero | I sparked that search a few times :) | 21:13 |
| bkero | (with the same project fenn is referring to)2~ | 21:13 |
| kanzure | so I went to the home today | 21:18 |
| fenn | for the price it's hard to find anything cheaper than myvu crystal in 640x480 | 21:20 |
| kanzure | hm, the piezo tweet goes 0.16 microns/Volt, max range of motion of 2.9 microns | 21:22 |
| kanzure | wonder if that's enough for moving a mirror to write with the LEDs | 21:23 |
| kanzure | I guess as long as 2.9 microns is the max size of features | 21:23 |
| kanzure | (erm, the entire design) | 21:23 |
| kanzure | the UV maskless lithography paper of course only had a min feature size of 17 microns. great. crap. | 21:24 |
| fenn | if you tilt the mirror you can get any range of motion you want | 21:24 |
| kanzure | the way that the STM guy did it was he cut up a piezo into four sections | 21:25 |
| kanzure | for +x, -x, +y, -y | 21:25 |
| fenn | yeah well that's not what you're doing | 21:25 |
| kanzure | but it could be. | 21:25 |
| fenn | look at speaker laser galvo's | 21:25 |
| kanzure | huh? okay. | 21:25 |
| kanzure | http://www.google.com/search?hl=en&client=opera&rls=en&hs=8rK&num=100&ei=zebKSfHjF8LfnQflhrjMCQ&sa=X&oi=spell&resnum=0&ct=result&cd=1&q=speaker+laser+galvanometer&spell=1 | 21:26 |
| kanzure | hard drive speakers? | 21:26 |
| fenn | blah. | 21:27 |
| fenn | gluing a mirror onto a hard drive actuator ought to work | 21:27 |
| kanzure | the rotational motion mechanism? | 21:28 |
| kanzure | or the arm? | 21:28 |
| kanzure | "The arm on a typical hard-disk drive can move from hub to edge and back up to 50 times per second -- it is an amazing thing to watch!" | 21:29 |
| kanzure | seems to be restricted to the range of motion of an arc | 21:29 |
| kanzure | heh | 21:29 |
| fenn | that's all you need | 21:29 |
| kanzure | yes | 21:31 |
| kanzure | okay, great | 21:31 |
| kanzure | I guess this means I get to play with hard drive drivers now or something | 21:31 |
| kanzure | erm, software meaning of 'driver' | 21:31 |
| kanzure | "Some early PC drives used a stepper motor to move the heads, and as a result had access times as slow as 80–120 ms, but this was quickly improved by voice-coil type actuation in the late 1980s, reducing access times to around 20 ms." | 21:32 |

| kanzure | I'm trying to figure out the actual size of the disks, not just the form factor of a hdd. I guess it's some portion of the overall form factor, but that doesn't really tell me much. | 21:35 |
| kanzure | particularly the radius so that I can figure out what an unhacked hdd will provide | 21:35 |
