Another Open Micromanipulator Project
Followers of μRepRap might be interested in the MicroManipulator project here. This is using some bespoke hardware, but it is all Open Source. By driving ordinary stepper motors as servos and using an array of magnetic rotation sensors and handmade bearings, he's managing to get movement resolution down to 50 nanometres.
As yet no fabrication capability, but there's no reason a μRepRap probe and deposition system couldn't be strapped onto it. There's some interesting control software there that might be useful too.
Anyway, here's the video intro https://www.youtube.com/watch?v=MgQbPdiuUTw
