    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.

    This one is pretty cool:
