    Levitating Speaker Plays Back Eerie Recordings

    Let’s face it, levitating anything is pretty fascinating — especially when you think there should be wires. This project puts a new spin on magnetic levitation by using a PID controller to levitate a speaker while it plays music!

    It uses the standard levitation setup — an electromagnet, a permanent magnet, and a hall effect sensor.

    Music is wirelessly transmitted to the speaker via Bluetooth
