Video: Plasma Speaker / Tweeter

Posted on Sunday, April 06 2008 @ 12:10:57 CEST by

Here's a video of a Plasma Speaker / Tweeter. Looks pretty cool:
Now built the completed circuit on a single PCB. Made vertical electrode setup from tungsten carbide (bottom) + stainless steel (top). Reflector made from PVC pipe with rear mirror, which can be backlit with RGB LED's. 1/2" gap at base to aid upward convection / cooling and improve flame stability. EHT now slightly lower and the gap size has been reduced. Track is 'Hold Me Now' from the Thompson Twins - chosen purely for it's good dynamic range, vocals & clever percussion ! Let me know if would like to see & hear any particular song - see what I can do
