Plasma Arc Speaker

This is my plasma arc speaker. The music your hear is from the arc and nothing else. There are no other sources of music in the room. It works by using a 555 timer to convert an audio input signal into a frequency modulated signal used to drive a flyback transformer. I will be modifying my design to produce a longer arc, which will result in a louder sound output.

Parts I Used to Make my Plasma Speaker:
1. 12V 50A Power Supply: http://amzn.to/1SqM8qd

2. Flyback Transformer: http://amzn.to/1NiRWkc

3. Ceramic ring magnet: http://amzn.to/1Sawjdq

4. Stainless steel electrodes(or tungsten). You can make them from rods found in printers. The larger, the better because small electrodes will melt.

5. Copper Grounding lugs: http://amzn.to/1VgaH05

6. Block of wood to mount the grounding lugs. http://amzn.to/1oOtSzn

7. At least 2 Logic Level MOSFETs- http://amzn.to/1RNckiZ The STP40NF10L I used are great because they have a super low Rdson at 5V and even lower at higher voltages.

8. Heatsinks - http://amzn.to/1SIhSaI Preferrably with a fan to further cool them down.

9. Heatsink compound: http://amzn.to/1VKF25j

10. NE555 Timer - http://amzn.to/25TnHfi Be wary of using other 555 variants as some are not capable of driving the MOSFETS directly.

11. 3.5mm audio cable: http://amzn.to/1MopfHL

12. Other components shown in the schematic.
