For this project we were hired to do a small hacking for a trade show. I worked on this with Molmol Kuo. Special thanks to Eric Rosenthal for the consultancy with the electronics and Zach for the support with the code.
The Electric Hoist that we’re giving has a built-in motor controller, a capacitor, and a pendent switch, that allows manually adjusting the directions.
The goal of the project was to move raise and lower a couple of pallets with other stuffs attached to the hook of this winch, not uniformly on time. So we hacked the motor to be able to control the direction from an Arduino UNO, but still allow any manual control from the pendent switch (when arduino is not running).
