Based on the venerable L298 Dual H-Bridge , Solarbotics has put together a really nice little kit for low-mid voltage level motor control applications.

You trade a little sweat equity for the few bucks you save over other offerings by fully assembling the kit yourself.

One of the nice bits about this kit is that it includes a 5V regulator to supply the logic portion of the L298 natively instead of relying on a 2nd supply voltage to the board.  This helps to make it very easy to drive either 2 DC motors or a single stepper motor from a microcontroller or other control device.

One of the things I need to do while working towards motion control projects is to practice some of the fundamentals.  I’ve worked with many of the concepts and mechanisms professionally, but more from the support end.  I haven’t touched the stuff for a few years now, and want to learn things at a more fundamental level.  In order to do this my plan is to pull motors and mechanisms from recycled equipment (printers, scanners, etc.) and set up a few labs for myself along the way.  Perhaps I’ll try to salvage some of the electronics as well with some good old-fashioned circuit bending.  I should be able to at least reuse motor drivers that are found, but for now I’m going to rely on inexpensive motor driver kits to allow myself more freedom to experiment.
