YouTuber Built a Real-Life [Electromagnetic] Mjölnir That Only the Worthy Can Wield
Inspired by Thor from The Avengers, one man has built a real-life Mjölnir (name of Thor’s magical hammer in the Marvel comic book and movie world) that is unliftable by anyone but him, so long as it is on a metal surface:
Using a capacitive touch sensor attached to the handle, an Arduino Pro Mini, and an electromagnet poached from the transformer of a microwave oven, YouTuber Sufficiently Advanced created a giant hammer that only he can pick up. The hammer’s creator then took his invention to the streets, tricking people into trying to lift the hammer.
