| lekernel | azonenberg: btw I don't think it would be possible to use a cd/dvd writer - those need the factory-made "groove track" to position the beam | 15:27 |
|---|---|---|
| lekernel | I think you could merely reuse the laser diode, not much more... | 15:28 |
| azonenberg | lekernel: thats what i meant | 17:24 |
| azonenberg | i'd use a bluray diode and a full custom mounting rig | 17:24 |
| azonenberg | obnauticus: Things have been going slow lately with school but things are coming along | 18:47 |
| obnauticus | now i do azonenberg | 18:47 |
| obnauticus | i have a bunch of chemistry equipment | 18:47 |
| obnauticus | and access to an e-beam and stuff | 18:47 |
| Action: azonenberg drools | 18:47 | |
| obnauticus | so i guess I could actually help | 18:47 |
| obnauticus | lol | 18:47 |
| azonenberg | evaporator or lithography? | 18:48 |
| obnauticus | both. | 18:48 |
| obnauticus | electron beam | 18:48 |
| azonenberg | e-beam without context could mean either | 18:48 |
| obnauticus | and photolithography | 18:48 |
| azonenberg | fancy | 18:48 |
| azonenberg | Is that in a real cleanroom or somebody's basement, though? | 18:48 |
| obnauticus | It's a real class 1 clean room | 18:48 |
| obnauticus | that I have access to | 18:48 |
| azonenberg | class 1? Shiny | 18:48 |
| obnauticus | http://www.purdue.edu/discoverypark/nanotechnology/ | 18:48 |
| azonenberg | the one at my school is class 100 | 18:48 |
| obnauticus | durpoopoo has one | 18:48 |
| obnauticus | super sexy | 18:48 |
| obnauticus | I have an elipsometer and stuff | 18:48 |
| azonenberg | nice | 18:48 |
| obnauticus | GA tech tried to make a comporable one | 18:49 |
| obnauticus | ran out of funding ion the middle of construction | 18:49 |
| azonenberg | Lol | 18:49 |
| obnauticus | they tried to make it 1/3 bigger than ours | 18:49 |
| obnauticus | but instead it is 1/3*ours | 18:49 |
| obnauticus | because $$$ | 18:49 |
| obnauticus | Purdue has $e8's for research | 18:49 |
| azonenberg | Nice | 18:49 |
| azonenberg | Right now the project is on hold until my roommate gets a few more parts to get his lathe up and running | 18:50 |
| azonenberg | then we're making a better spin coater | 18:50 |
| obnauticus | ah | 18:50 |
| azonenberg | the current one is made from 2x4s and a power drill | 18:50 |
| obnauticus | I have access to an entire machine shop too | 18:50 |
| obnauticus | with HAAS CNC and shit | 18:50 |
| azonenberg | Shiny | 18:50 |
| obnauticus | that's jank | 18:50 |
| obnauticus | I have 3 machine shops | 18:50 |
| obnauticus | purdue is fucking awesome | 18:50 |
| azonenberg | We're trying to avoid using too many fancy resources when possible though | 18:50 |
| obnauticus | yeah | 18:50 |
| obnauticus | for obvious reasons | 18:50 |
| azonenberg | since the whole point is to keep it DIY accessible | 18:50 |
| obnauticus | but for testing and proof of concept for methods | 18:50 |
| obnauticus | i can test fancy stuff | 18:50 |
| azonenberg | Oh, yeah | 18:50 |
| obnauticus | just fyi | 18:50 |
| azonenberg | I have access to a filament evaporator outside the cleanroom (easier/cheaper to get time on) | 18:51 |
| azonenberg | that i've been using for metal deposition | 18:51 |
| azonenberg | and we have a machine shop too | 18:51 |
| obnauticus | ah | 18:51 |
| azonenberg | But a lathe in the living room is just so much more fun | 18:51 |
| obnauticus | You're aware of FSAE, right | 18:51 |
| obnauticus | you go to RPI so you're bound to have friends on it | 18:51 |
| azonenberg | My roommate is on it | 18:51 |
| azonenberg | the other orommate | 18:51 |
| azonenberg | i have four lol | 18:51 |
| obnauticus | lol | 18:52 |
| obnauticus | I am/was on my university's team | 18:52 |
| azonenberg | nice | 18:52 |
| Action: azonenberg uploads pic | 18:55 | |
| azonenberg | http://i.imgur.com/duk4n.jpg | 18:56 |
| azonenberg | My living room | 18:56 |
| azonenberg | in the middle of a few projects so its a tad messy | 18:56 |
| azonenberg | but you can see some of the lab areas | 18:57 |
| azonenberg | Lathe at left, server rack on the right, wet bench just right of center | 18:57 |
| azonenberg | dead center in the far back is the electronics assembly workstation and, behind that, the microscopy bench | 18:57 |
| azonenberg | hows that for a home setup? :) | 18:58 |
| Sync | obnauticus: haas machines suck | 19:00 |
| Sync | but haha, you do all that fancy cleanroom stuff, we just ... don't | 19:01 |
| obnauticus | Sync yeah, i know | 20:10 |
| obnauticus | haas aren't that great | 20:10 |
| obnauticus | i have access to actual high quality CNC's as well | 20:10 |
| obnauticus | the names escape me at the moment | 20:10 |
| Sync | http://koti.mbnet.fi/kizmo/misc/haasbuttons.JPG | 20:11 |
| obnauticus | rofl | 20:11 |
| obnauticus | ah | 20:12 |
| obnauticus | it's an MB10 | 20:12 |
| obnauticus | and whatever the bigger one is | 20:12 |
| obnauticus | fryer ones though | 20:12 |
| obnauticus | an MB10 and MB15 | 20:14 |
| obnauticus | those are the CNCs i use most of the time | 20:14 |
| obnauticus | one doesn't have an auto tool changer so it works pretty fast | 20:15 |
| Sync | tool changers do not hinder machine performance | 20:27 |
| obnauticus | Sync they do | 22:46 |
| obnauticus | they limit your effective range | 22:46 |
| obnauticus | your Z travel, specifically. | 22:46 |
| Sync | that depends on the machine, the cnc machines I worked on did not have such issues | 22:47 |
