Hope it all goes well dude, I'll be following the build diary. I've seen adz's one, Ceros, and that looks pretty good. I may have to look for parts on the forum, or maybe see if the heavy Eric is still available, and spend some money on that. All being well, something may go right. We have all sorts at the college, Milling machines, Lathes, CNC machines, 3D Printers (Albeit them being small makerbots, though they'd be amazing for antweights). I've tried to make a bang bang servo/microswitch speed controller before, it didn't go too well, although some sort of relay should suffice nicely. barring that, I'm sure I've got one for a feather somewhere, and botbitz is supposedly cheap.
