|Mjolnir powered by Arduino|
The Mjolnir only answers to Thor and is inscribed with the words: "Whosoever holds this hammer, if he be worthy, shall possess the power of Thor."
Now, Allen Pan from the Sufficiently Advanced YouTube channel created this Mjolnir replica but with a twist, he uses strong electromagnet that was embedded to the hammer controlled by a finger scanner that was attached to a microcontrollers (Arduino that powered internet of things devices and project).
Allen went to Venice Beach and challenged passersby to lift the legendary hammer.
