Replica Mjolnir with Fingerprint Scanner

In the Marvel Comics universe, Mjölnir is a special weapon in that only the worthy can lift. Most of the time that only means Thor. Few other heroes or people have been able to wield the magical hammer. YouTuber Sufficiently Advanced came up with a practical version of the hammer that works in real life. His Mjölnir contains an electromagnet and a fingerprint scanner. The programming prevents anyone else from picking it up. In the above video, he takes it to Venice Beach and tries to get bystanders to pick it up — it’s rather amusing.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. Reminds me of the (sadly decommissioned) sword in the stone ceremony at Disneyland.

    If you don’t know, they used to do a ceremony where Merlin would would have several guests try to pull out the sword. Everyone would fail (always adults) and then finally a little kid would succeed.

  2. Hi,
    I like to teach kids electronics using Arduino and Raspberry Pi in my free time. My son and our neighbors get excited around Halloween because they can help build something.

    This year, I have not started on a project. When I saw the YouTube video with mjolnir, I immediately started searching for components. I can see the Arduino, a solid state relay, couple of transformers and bunch of batteries. I am not sure how the transformers are driven from 4 x 12 SLV batteries.

    If you guys have a kit or schematic, I will love for my kids to build this and prank our neighbors.
    Thank you,
    Gaurav
