Plasma Speaker - No actual speakers needed, just lots of electricity
Brandon Davenport
This chunk of wood with nails in it has the same capabilities as a speaker - sounds to good to be true right? Well it is true and it is utterly awesome! A plasma speaker is a device that generates a super high voltage electrical arc that makes purple light and has the ability to produce sound, or in this case music. The only audio equipment needed is an audio source like an iPod or in this case a CD player, and the electricity does the rest of the work, vibrating in the air and producing sound.
How to make your own
The creator, Plasmana has put together a nifty little how-to over at Instructables and trust me, its not for the in-experienced. If you don't know what a UF4007 diode is, or what a Flyback transformer is, we don't recommended you dive into this project, instead enjoy the video! If you are some sort of whiz at this stuff, by all means, go ahead and slap one together, then send us your creation! We would love to see it (if you have the guts to do so).
