Hasta La Gadget!

If Thor’s Mjolnir hammer wasn’t bad enough on its own, the heavyweight hammer is also capable of summoning lightning from the heavens. Caleb over at Hack A Day thought about this and decided he needed his own electrified Thor’s hammer.

Instead of standing in the middle of a field during a lightning storm, Caleb decided to go with something a bit safer. With the help of builder Staci Elaan, Caleb’s Mjolnir is outfitted with a working, battery-powered Tesla coil. Despite outputting 80,000 volts, the Tesla coil is actually quite safe – just zapping subjects with a tiny, tickly sensation, and not the full force of Thor’s mighty hammer. And since it’s a Tesla coil, it can even light up fluorescent bulbs placed near it.

That was fun, though I do wish the lightning bolts it emits would be a bit bigger. I guess you’d need a larger, plug-in Tesla coil – and Thor would probably have to wear a Faraday suit.

Check out more details on the build over on Hack A Day.

Tesla coils are one of scientists’ go to tool for making science appealing to kids. As if producing your own lightning wasn’t enough, tesla coils can also be used to produce music by pulsing its sparks at appropriate frequencies. You can do all that and more with the oneTesla DIY kit. Although you might not like the “more” part.

The oneTesla was conceptualized by Bayley Wang, Heidi Baumgartner and Daniel Kramnik. All three are members of MITERS, a student-run tinkering shop at MIT. Which brings us to the catch of oneTesla: you have to build it yourself. Even the inventors admit that it’s best left to people with advanced skills in soldering and electronics. But that’s partly the point of the kit. I’m sure you’ll learn a lot about electronics even if you just watch or assist in assembling the oneTesla. And once it’s built, you can do this:

Flight of the Bumblebee or Attack of the Mosquitoes? The oneTesla has been such a hit at Kickstarter that its cheaper pledges have already sold out; as of this writing you’ll have to pledge at least $299 (USD) to reserve a unit, and you’ll have to wait until May to receive yours. I say it’s worth it.

Two things that are always cool: Tesla coils and Nerf guns. One thing that’s cooler than those two things: a freaking Tesla coil Nerf gun. That’s right. Rob Flickenger converted a Nerf gun into a handheld Tesla coil. Freaking. Sweet. More »
