Ball Ballancer - PID test rig

This is a ball balancing test rig for experimenting with PID tuning. PID is a control loop feedback system. A Ping Pong ball is balanced on an aluminum angle. The angle is tipped side to side supported by a pivot. A hobby servo is used to move the angle. The caps on the angle have mounting holes for a Adafruit VL53L0X breakout board (laser distance sensor). Included in the files are the pivot, end caps, and servo base.

The pivot supports a 1", 1/8" thick aluminum angle. My angle is approximately 500mm in length. This length is the maximum reliable range for the VL53L0X using a white ping pong ball target.

Also included are the Fusion 360, and Step design files if you wish to make modifications.
