Very sweet! Im looking forward to any projects you might put up for the Firefly. Are you going to put links to them on your site or just list them here?
I'd like to do a servo controller for up to five servos via RS232 just like the oodles of commercial ones (Pollu, Scott Edwards, Parallax etc...)
Why buy when you can program and build one yourself. Check out the Mongoose update in the robotics section of these forums for one of the next kits coming out.
