Wow, just saw this log... excellent work! I'm gonna go find a class I can join! Only half joking... When I was at the MakersFaire this weekend there was a place called techshop which was recruiting students to learn how to use their machines and get lab time... wish it was closer. http://www.techshop.ws/ I'm thinking a community college might be closer/cheaper... but might not have all that cool stuff. Kewdtz, how much liquid can fit in that res?
