| kanzure | http://www.personal.psu.edu/u0y/nanoreef/papers/360204hs.pdf | 10:21 |
| kanzure | delinquentme: sure.. http://diyhpl.us/~bryan/irc/2010-05-28_puma500.jpg is mine | 10:22 |

| kanzure | hi itdnhr, jmil | 10:30 |
| * itdnhr waves at kanzure | 10:33 | |
| kanzure | timschmidt: you around? | 10:33 |
| kanzure | itdnhr: tim is wanting to do some welding-via-reprap | 10:33 |
| kanzure | actually i should be talking about phreedom, he was the one doing wire edm in here before | 10:34 |
| kanzure | phreedom: ping? | 10:35 |
| jmil | hey kanzure | 10:35 |
| kanzure | howdy jmil | 10:35 |
| phreedom | kanzure: pong... | 10:37 |
| kanzure | phreedom: how's that edm machine :P | 10:38 |
| itdnhr | phreedom: Wire EDM via pulsed discharge from supercaps sound interesting? | 10:38 |
| phreedom | you don't really need any super caps | 10:38 |
| kanzure | jmil: anything new? did your paper get published | 10:38 |
| phreedom | regular ones will do :) | 10:38 |
| phreedom | kanzure: I'm out of free time now :( | 10:39 |
| phreedom | hw stuff has to wait | 10:39 |
| itdnhr | there's a project similar to what I'm talking about in the hackaday archives, but the guy who did it is using a PIC, a custom PSU, etc, compared to an arduino mega and computer PSU - 'standard' fair. | 10:39 |
| itdnhr | phreedom: I happen to have a set of 35F/2.5v supercaps with 5mOhm internal resistance | 10:39 |
| phreedom | I don't think I ever encountered an edm tool that used 2v | 10:41 |
| delinquentme | kanzure, its cute.. what do you use it for? | 10:41 |
| itdnhr | I have seven of them; planning on using a 5F/12V bank | 10:41 |
| itdnhr | 2v should theoretically work, but would require a prohibitively large level of accuracy; not a whole lot of wiggle room between your business end and metal | 10:42 |

| kanzure | delinquentme: it's a giant lamp rack right now | 10:48 |
| delinquentme | haha gotya | 10:49 |
| kanzure | lamp rack. what? i meant coat rack or lamp stand | 10:49 |

| kanzure | jrayhawk: supposedly i'm doing post-update image generation scripts today | 11:03 |
| kanzure | i have some stuff in skdb.git like iges2png and step2png | 11:03 |
| kanzure | plus stl2pov (and i'll need to write openscad-to-stl-to-pov as a quick wrapper) | 11:04 |
| kanzure | iges2png works by using opencascade to convert from IGES to STL | 11:04 |
| kanzure | opencascade uses opengl for visualization but it seems to require xorg to be running | 11:04 |
| kanzure | i was wondering if you have any hints on how i could molest it to run headless and still let opengl do its thing | 11:05 |
| kanzure | opencascade's "save a png of the object" function is literally "take a screenshot of the active xorg session" | 11:05 |
| kanzure | so if you have windows in front of the opencascade viewport, those windows will be present in the screenshot | 11:05 |
| kanzure | i should note that the opencascade developers are.. awful | 11:06 |
| g4k | kanzure: what's an iges file? | 11:10 |
| kanzure | it's a lot like STEP (ISO 10303-21) except without useful descriptors or words in the file format >:o | 11:11 |
| kanzure | it's a solid geometry file format for specify surfaces and boundaries of a 3D object | 11:11 |
| kanzure | (both STEP and IGES fit this description) | 11:11 |
| kanzure | however, neither of these are parametric file formats :/ | 11:11 |
| kanzure | which reminds me.. someone should bug me to release my notes on the solidworks file format. i've made some progress in reverse engineering it but i haven't put the notes anywhere usefl | 11:12 |
| kanzure | *useful | 11:12 |
| kanzure | rest of the wire edm conversation from above is over here: | 11:14 |
| kanzure | http://groups.google.com/group/openmanufacturing/t/affcd3e8ac2750fe | 11:14 |
| kanzure | in case anyone is actually trying to follow this :x | 11:14 |
| g4k | are you caffeinated, kanzure ? | 11:15 |
| g4k | or perhaps manic | 11:15 |
| g4k | comparatively, which is easier as a first project: gel electrophoresis, or flow cytometry? | 11:17 |
| kanzure | i'd like to be manic but i don't think i am | 11:17 |
| kanzure | i just abuse nootropics or something | 11:17 |
| g4k | yeah, isn't caffeine considered a nootropic? | 11:17 |
| g4k | or is it just an anxiolytic now ;p | 11:17 |
| kanzure | sure, but i'm actually on adderall | 11:17 |
| g4k | ah, np then buddy | 11:18 |
| kanzure | huh? | 11:18 |
| g4k | no problem* | 11:18 |
| kanzure | that's not what i was.. nvm | 11:18 |
| g4k | anyway, let me abuse that hyperactive brain of yours for a minute | 11:18 |
| g4k | gel electrophoresis or flow cytometry? | 11:18 |
| kanzure | i'm still trying to decide | 11:18 |
| kanzure | would you be building your own power supply for gel electrophoresis? | 11:19 |
| kanzure | i.e. http://openwetware.org/wiki/DIYbio:Notebook/Open_Gel_Box_2.0 | 11:20 |
| g4k | http://www.bch.cuhk.edu.hk/workshop-dna/background.html | 11:20 |
| kanzure | i.e. http://88proof.com/synthetic_biology/blog/archives/303 | 11:20 |
| g4k | this guy is using 8 9v batteries | 11:20 |
| kanzure | g4k: and you know about the hand-based methods too? i.e. water bath setup | 11:21 |
| kanzure | i guess a water bath setup is "technically" easier in the sense that you don't have to build much | 11:21 |
| kanzure | what the hell. sorry, i was assuming you were doing PCR | 11:21 |
| kanzure | i'm going away now that i've disgraced myself. i'll brb if you leave any questions | 11:22 |
| kanzure | g4k: gel electrophoresis, especially if you want community help/assistance/troubleshooting. | 11:22 |
| g4k | alright | 11:24 |
| kanzure | i mean.. in terms of quantity of available help ;) not in terms of "we won't help you" :) | 11:25 |
| g4k | i know | 11:26 |
| g4k | sounds fun :) | 11:27 |
| -!- JaredWigmore is now known as JaredW | 11:29 | |
| g4k | kanzure: thank you for pointing out openwetware.org, holy grail man | 11:38 |
| kanzure | their registration process is a little fucked up | 11:51 |
| delinquentme | g4k, you're a researcher? | 11:53 |
| delinquentme | and kanzure you were sending him to a gel electrophoresis help forum? | 11:54 |
| kanzure | no? | 11:54 |
| kanzure | i showed him some power supply schematics | 11:54 |
| kanzure | g4k: i help maintain the diybio faq on openwetware.. i.e. http://bit.ly/diybionews which might be interesting if you're into hype | 11:57 |
| archels | 1.5kV @ 1mA? Maybe you can hack the HV PSU from an old laser printer. | 11:59 |
| g4k | delinquentme: not exactly, i'm a guy looking for stuff for our hackerspace to do | 12:09 |
| delinquentme | g4k, wheres ur hakerspace:D? | 12:10 |
| g4k | Orlando, FL | 12:15 |
| g4k | going to buy a television too large for my room, bbl! | 12:16 |
| delinquentme | http://88proof.com/synthetic_biology/blog/archives/318 with something like this ... does it matter what language you hack it with .. just so long as its a core language? | 12:19 |

| delinquentme | kanzure, if my teeth are messed up .. du have any cheap ways of hacking oral inserts to fix them | 15:15 |
| archels | lol. | 15:15 |
| delinquentme | ^_^ | 15:18 |
| delinquentme | im tripping out over it that for invisalign they want 3 grand | 15:18 |
| delinquentme | F that | 15:18 |
| delinquentme | theres gotta be a cheaper way | 15:18 |
| delinquentme | and its like MINIMAL movement like after i get wisdom teeth yanked .. one tooth needs move liked 3 mm | 15:19 |
