Thor’s hammer is one of the coolest weapons in the superhero universe. Called Mjolnir, it can summon lightning, crush through pretty much anything and help the Norse god fly. No wonder Caleb from Hack A Day wanted one for himself.
But the gifted builder wasn’t looking for yet another simple prop that looked like Thor’s hammer, he wanted something that actually produced bolts of lightning. Armed with his own DIY superpowers, Caleb Kraft set out to create a foam replica of Mjolnir and sought the help of battery-powered Tesla coil maker Staci Elan, who provided a tiny but effective device able to produce 80,000 volts of electricity. Caleb says he had to make a choice: “I was either going to go portable and live with small arcs, or make this a stationary piece and hide a giant Tesla coil in a base. It would have bigger arcs, but I couldn’t carry it around.” In the end, he opted for the portable version, fitting his light but realistic looking hammer with a a small 12v powered coil. It creates 3″ arcs when going to another piece of metal, and can power on light bulbs if you hold them close to the hammer. Nowhere near as cool as the real Thor’s powers, but pretty awesome for a mere mortal, wouldn’t you say?
