Build a Set of Plasma Speakers for Electricity Generated Sound [Science]

Speakers with cones and drivers? That’s not mad scientist enough for you. The only kind of tunes you want to listen to are those generated by high voltage electrical arcs. This weekend build a set of plasma speakers and rock out like Nikola Telsa.

What are plasma speakers? Properly modulated electrical arcs can produce music rather than just the Telsa-coil like zapping you’d expect. The modulation changes the way the arc of electricity moves the air around it just like the vibration of a violin bow over a string can produce a pleasant or discordant sound. Watch the video above to see a plasma speaker in action–you may want to turn down your speakers at the beginning as they start the video with the unmodulated arc which is quite noisy.

Want to build a set to wow your neighbors (and risk blowing out their pace makers in the process)? Hit up the link below to read more.

Jason Fitzpatrick is warranty-voiding DIYer and all around geek. When he's not documenting mods and hacks he's doing his best to make sure a generation of college students graduate knowing they should put their pants on one leg at a time and go on to greatness, just like Bruce Dickinson. You can follow him on if you'd like.
