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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
