I figured if you haven't heard of it already, you might want to check it out. I'm currently trying to build one of these. It's a lot more involved (computer wise) to setup than I origionally planned, but i am making a lot of progress with the mechanics and 'some' of the electronics. The group may benifit after it is working. It makes copies of itself!! If any of you are interested in lending a hand getting it going, I could certaintly use the help.
Bring it out! If you can get the tools and parts you need to work on even a piece of it to a meeting, I would be willing to help. I'm pretty sure everyone else would be, too.
It'd definitely be great to see one of these in person.
