Allen Pan has made a replica Hammer of Thor in a quest to become the new God of Thunder. Using an Arduino Pro Mini micro controller, fingerprint and touch sensors, Allen created a magic of magnets.
The trick was creating a strong magnetic field, so it feels too heavy to lift. When the electromagnet is switched on, it locks to anything made of metal.
The electrial enginner made use of a fingerprint scanner inside the handle to turn off the strong magnet and be able to lift the hammer.
Pan took it out on the streets of LA and asked passers to try to lift the hammer, as you can see in the video below:
