How does it work ? How can I make others ?
I bought it about 7 years ago at a gadgets store, never found it advertised on the net, but also unsure on how to search for it. It is a 'novelty' type gadget; about 60 cm. long, 3 cm. diameter clear glass tube, has a built-in microphone and the driving electronics at one end of the 'fluorescent' ; powered with a 12VDC wall adapter.
The bright red plasma glow grows toward the end of the tube at the loudness of sound, it does not modulate its brightness, modulates its lenght.
Anyone knows anything about ?
