Wireless light bulbs with a Slayer exciter

slayer rocksWhile playing chiptunes, creating lightning, and illuminating fluorescent tubes with a homebrew Tesla coil is awesome, they’re not exactly the safest electrical devices around, and certainly aren’t easy or cheap to build. There’s another option open if you’d like to play with strong electromagnetic fields; it’s called the Slayer exciter and is simple enough to light a few fluorescent bulbs … Read the rest

Modulator box connects iPod to Tesla coil

tesla-coil-modulator

This pass through audio modulator lets you playback stereo audio on two Tesla coils. But don’t fret, you can just use mono files if you only have one coil on hand. On one side there are inputs that connect to the audio source. The other side drives the Tesla coil, switching it on and off based on the relationship … Read the rest

Home built stun baton turns you into a cop from Demolition Man

home-built-stun-baton

It seems much like a cattle prod, but [Pode Coet] definitely had people in mind when he built this stun baton. It’s not for the faint of heart — especially since a wrong move could stop your ticker cold. But the design and fabrication are top-notch, and he didn’t hold back when it comes to build images and details.… Read the rest

Mains rated solid state relay test box

We like our nice, safe, 5V prototyping projects where the only thing that might get fried is a chip. But there are times when you want to switch appliances for one reason or another and then you’re going to want a mains rated relay. [Viktor] got tired of having exposed high voltage on the bench during the prototyping stage of … Read the rest

244 9 Volt Batteries in Series – Arcing Ensues!

244-9v-batte…n-series

Here’s another hack that we would definitely discourage you from trying at home, 244 9 volt batteries wired in series. There’s really not much more to it than that, but [jersagfast] takes this setup through its paces arcing through air first, a LED light second, and then a CD. The air arc is probably the most impressive, but a … Read the rest

[Staci Elaan]‘s awesome portable tesla coils.

We stumbled onto [Staci's] videos a while ago when we posted this big tesla gun. While it wasn’t the first portable coil we had seen, it was certainly an impressive implementation. In the comments we found [Staci] had already been making these for a while. Hers were big and small, had awesome modulation, and looked freaking cool too.

It … Read the rest

hijinks at 50,000 amps

So you happen to have a really beefy transformer sitting around in your living room. What are you going to do with it? Short stuff across it to watch it glow of course!

This video is exactly that. While we flip flopped between “what is this guy doing?” and “ooooh, look at it glow!”, we thought you would surely enjoy … Read the rest
