Introduction
This project was actually done some years ago by some great posters on RCGroups and DoItYourselfDrones. You can read the original threads at these two links:
Basically, this is a dynamic balancer for motors and props that can be built for under $50. In the original write-ups there are two versions of the control board and firmware but this build only covers the version that uses the Teensy micro-controller.
