Plasma Speaker / Tweeter - Fun In The Dark :)

Connected the RGB LED's to a simple binary ripple counter. Some of the filtered audio is fed to the clock input, to create a sound-to-light sequencing effect. Looks really nice in the dark - It's a pity the camera doesn't pick up the vivid intensity of the colours.

Clearly the low frequencies are limited but the length of the ionized gas i.e. distance between electrodes. What is the maximum possible distance between electrodes? Could this be made say a metre high like current floor standers? What are the practical implications?

@ImprobableWizard

You need 1.1KV (1100 Volts) per millimeter, to create an arc in air. So, a 1" plamsa arc between 2 fixed points requires approx 26000 volts. A meter long discharge would require well over 1 million volts with 50% relative air humidity.

kool listen to music and zap bugs at the same time lol

Amperage kills.

[magicstix0r]

Nice. I'm assuming the frequency response you can get out of this thing is directly related to the length of the arc?

[Henzzman]

@timetec This can be done with a walton-cockroft multiplier or with a marx generator.The thing is how to modulate the arc to music.Though i think that a tesla coil may also be easily capable for 1 meter arcs and still playing music.No doubt all this will draw insane amounts of power,to create a sound that is beaten by the cheapest speaker there is.Still a cool idea.

@xxmrbloodxx You get jolted, duh

[dumle29]

are these for sale?

[robot797]

@timetec do you sell it?

[seriousamm]

@acronus

lol so true. its pretty badass

[cjellwood]

Now thats what I call 'Live Music' lol! (ouch)

[barbienipper]

Are you using tungsten electrodes?

[xxmrbloodxx]

what happens if you touch it?

[aaa801]

how would i go about making one of these

i have the equivelent of a radioshack near me
