Controlling Hand Drill with Roboduino using Arduino

This will explain how we re-purposed a hand drill to re-spool solder using a roboduino (arduino compatible), two servos, and a DIY encoder.  While one could use TRIACs to play with the AC power going into the drill, just using a servo to control the throttle is simple and avoids the pesky high voltage.
