Drawbot 3 is underway

Well, I've got all the boards designed, and all the last of the parts arrived today from Digi-Key.  Now I'm starting the actual build by etching the first board.  This is a USB to RS-485 converter, and will provide my laptop with an RS-485 bus.  Tomorrow I go buy a new soldering iron, and some damn sharp tweezers.

I need to say thanks to Smallbox and Angie's List for the $1000.00 Nice Grant that makes this all possible.
