Martin Grebe tipped us about this cool plasma tweeter in the comment section of this article. Timetec did a fantastic job on building this unit! His musical selection isn’t my favorite but the great operation sure makes up for that.

"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."
