Hi, i am a new to electronics, and i would like to build my own PID controller

Before i jump into the water i would like to have your opinions on what do you think would be a simple for me to control with the PID controller that i am going to build?
My aim is to make an experiments on a real system, with possible disturbances.
  • Controlling a voltage across a capacitor
  • Controlling a temperature (for example of filament lamp or something)
  • Controlling the position of a motor
  • Controlling the velocity of a motor
  • any other suggestions?
thanks

I've always wanted to build a ball balancer, but never got around to it.

My version was to have a ball bearing on a tilting N scale section of railroad track. A motor would tilt the track, and the position would be determined by using one rail as a voltage divider and the other to sense voltage at the position of the ball. I *did* built the main frame and the track, and the electronics for position sensing -- which worked. But I left it at that.

Ultimately, I wanted to build a clock: three rails and three balls. Each rail/ball being Hours, Minutes, and Seconds. The seconds track would 30 seconds "long" with the ball oscillating between the two extremes of the track every minute.
