My boyfriend made me an arduino controlled glass bead setup

I showed him all the posts on this sub and he got excited about being able to overengineer a gadget for me lol. It's an arduino that controls a motor that has a little pulley system in the top to drive the shaft with the magnet. The knob on the right spins to control speed. We're both electrical engineers so I also fully could have made this but I am a passenger princess first, woman in stem second 🥰 polish is illusionist by mooncat
