Testing banggood plasma speaker Tesla coil, 15w DC 15-24V 2A

!!(With this test there is one part missing (C1), i found it and i will make new tests later)

Testing with 9v battery, or what is left of it.
Tesla coil work with fluorescent light quite close.

I replace the leds cause i first solder them wrong. Minuses are closer to the coil.

I tested also this with 12V, 2A- Adapter and there was good plasma showing. Wire was getting really hot and cutted..

If you have idea how to build toroidion or topload to these, put it on the comment section, thanks...
