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."

aw how ya gonna hate on the thompson twins alan?

The problem is the cancerous ozone it makes….

You people sure are gullible as hell.

Sounds like ME is a disbeliever. These devices are real, they don’t sound as good as real speakers but they are amazing!
Permalink
Are you willing to release the diagram on how to make the PCB?
Permalink
Forgive me for my sudden lapse in intelligence (just woke up), but is the sound coming from the arc? That is awesome! It even gives off some bass. I want to make one!!!!

Don’t veleive such a crap. Sound is waves of air and how do the glowing discharge can ever sways an air with precession of music oscillations?

*beleive. It’s a bit too early for 1 april.

Right as soon as I played this video, an Alice Deejay song started playing on my pandora, (internet radio station) how random is that?
Permalink
OMG, it’s the same song too.

To anyone who doesn’t believe it, this has been done before by many other people:

@evernight
the plasma produces heat and the heat causes expansion of the air around it causing a pressure wave to form, when the arc stops, it collapses and the other part of the wave is formed. the light is a byproduct, the light doesnt make the sound, its the heat.

I found this stuff so cool, and i’d love to build one, maybe next year…
I also leave this comment cause i was listening to an internet radio, and the same alice deejay song was playing just when i started the video… that was funny… but it became real funny when I read Takato’s comment !
cheers

Another video been uploaded with a track by Dream Theatre.
a world apart from that Thompsson twins tosh (try saying that fast 🙂
You can actually see the plasma moving to the music – unreal!

I did something similar for a science project back in 1972. Used a torch flame to provide an ionized path and drove it with a modulated high voltage DC supply.

where’s village people? jaja!
Ac/Dc rules dude

see this and tell me how good that is? http://www.plasmatweeter.de/

Very nice job. My dad had a pair of them back in the late 60s. Even piezoelectric tweeters can’t reproduce sound as crisp and clean as plasma. I’d love to have the schematics. He would get a kick out of it if I could build him a pair like yours.

yas man
here you have a shem. http://www.volny.cz/jmartis/singing_arc_fm.png
i’m gona make my wwith this shem. there is the ver vith tl494 but it dosent reproduce the mid’s vell as the sg3525 , here is some material http://www.hvlabs.com/plasmasonic.html so you can make a cheep one .
You can even use high voltage http://www.youtube.com/watch?v=vZfLGrRodCY like here 300 V DC
See ya…

This is not new; my father told me when he was in college(late 40’s-early 50’s) he had a friend @ M.S.U. in Lansing MI that had a propane fired tweeter and horn setup-Dad said it sounded
amazing back then, better than anything he heard since…
plasma’s inherently efficent, lightest weight to power of any,
except (maybe) electrostatic’s…
