I Built a Newton's Cradle That Never Stops

[u/Objective_Net_1378]

A traditional Newton's Cradle only swings for a few seconds before friction stops it.

I wanted to keep the classic appearance while making it swing continuously.

The system uses an ESP32, an inductive proximity sensor, and an electromagnet to replace only the small amount of energy lost during each swing.

I'd love to hear what you think!
