The Plasma Speaker

Step 8: Final test

Okay, you are very close...
Test your plasma speaker to make sure if it is working or not.

If its working, let out a sigh of relive that you did it!

If its not working, don't overreact of frustrated, (I know it is very frustrating when something does not work).
A few things can go wrong with this circuit, here is a list of some problems...

• Solder bridge - That is the most common problem in soldering.
• Some connections missed out - Also another common problem...
• Damaged components

Try find and fix the problem, there is no point giving up - unless you are really lazy to do so...

After you got your plasma speaker working, it is a good idea to the circuit into a project box. I will protect the electronics from being damaged from foreign objects and protects people from an electrical shock.

This is my first soldering project fyi, but just a funny bit of information, when I hooked my circut up to a speaker(at a lower voltage) it was not playing MY music but intead it was picking up AM1100 radio, what could cause this? Its kinda funny XD

You'll protect our electronics from being damaged from foreign objects? Thanks man!

So, what pins we connect in flyback transformer??

I don't know how much it will help, but why don't you try using the heat sink off of a CPU? Include the 12V DC fan on the 12V DC power supply. Or put 2 fans. I know that the audio might be overpowered by the sound of the fans, but that could be fixed with an in-line 100 Ohm 10 watt pot. Those ratings seem to work best for controlling fan speeds. You could also go automatic by using a thermocouple input into a small 10 watt amplifier to drive the fans. Don't forget the heat transfer paste!

 Because it is, the two wires are joined, the negative of the higher power source  goes to the black wire going downwards and the coil is joined to the heat sink that acts like the center pin. ;)

 why does it look like there are two wires soldered onto the same pin of the mosfet?
