For me, one of the most exciting aspects of working with the SX and programming it in SX/B is the ability to create accessory devices like last month's animatronics controller. With what we've learned, it seems that the next logical step is a Parallax AppMod-compatible device; since Parallax already has a great servo controller (the PSC) that uses this protocol, let's build a compatible motor driver. And for those just getting started or don't want to have a PCB etched, have no fear! We're going to whip this baby together with a handful of parts and Parallax's incredibly low-priced SX28 proto board.
