FM Plasma Speaker Version 2 (HD)

All audio comes from plasma arc. Incoming audio signal is frequency modulated using the SG3525. The high voltage stage is a half bridge driver wi...

@PeteDog444 In terms of frequency modulation, I think they both had similar audio quality. However, I had much better luck with PWM and a 2 switch forward flyback power stage using the TL494 and some driver ICs. The power output is linear with PWM unlike FM which is more hyperbolic, causing dis...

  @Alex1M6 It was the SG3525AN DIP package.

  @AutotuningMensch In my final design, I used a splitter to send the audio to a normal sub woofer. The sub woofer plus the stereo plasma speaker system delivered results on par with retail 2.1 speaker setup.

  @TheRoknemec Thanks for the feedback! I don't remember the exact model number (school owned camera), but it was one of the first Sony 1080p Handycam AVCHD HDD that they sold. Great camcorder!

Stereo Plasma Speaker - PWM

This is the final, completed version of the plasma speaker system. To get the highest audio reproduction, PWM was used (PWM is linear). The setup...

@2ManyNoobs Unfortunately, we didn't get around to making any specific measurements, but it is quite loud...on the order of any other $50 pair of computer speakers. The same is true for a frequency response graph...we didn't get around to it, but you are right. It definitely rolls off on the lo...

  @jayynecobb I agree...poor music choice. Unfortunately, I was stuck with my buddy's Ipod selection on the day of filming. I'll definitely have to try it out with the Darth Vader theme.

  @thunderdrums009 We used a rapid prototyping machine, which basically was a 3D printer, to make the cones.

  @Rythymoxide2020 The project isn't that expensive...once you get a working design. The expensive part is replacing the FETs, board, and other components when they blow up while your're tweaking the design. If you did it with perfboard and didn't have a horn/plexiglass enclosure it's probably $2...

  @ottanicubano88 Thanks for the feedback...feel free to ask any questions as you make your design. The schematics available online provide great starting points.

  @mikkelmmk18 Although we didn't do any official testing, the audio quality, especially the high frequencies, is exceptional. Also the thickness of the beam in this design allows a relatively high volume and extends the frequency response to about 100 Hz. When a sub is added, it works great as s...

  @aviationist This particular set up does not generate very much ozone if any at all. The beam is very stable and is contained in the plasma; ozone is created in other designs/tesla coils because they arc into open air. However, UV radiation is another matter. I haven't tested it, but I'm sure ...

@trampolinist2 To be honest, I have no idea what the name is. I had to change the audio because of legal reasons, and I just picked the most random beat in the audioswap library.
