Fixed frequency/music/pulse arc extinguisher for Tesla coil

Classic solution, with long and short pulse width switching, low frequency pulse switch, music fixed frequency switching,
long and short pulse width switching (the button on the far right)
to switch
 
the low frequency pulse switch (the one on the far left) by modifying the 555 peripheral capacitor
, still by modifying the 555 peripheral capacitor When switching
to this mode, the pulse width can be turned on long and violent.
Music fixed frequency switching (the one in the middle)
changes the path between the two chips above and the 555 enable pin below.
Square wave music can be input from the audio interface (with left and right channel switch)
Don’t set the pulse width too high at the beginning (don’t blame me if the tube bursts).
The frequency is
393 and must be genuine, otherwise the music function may not work or even be usable. If
you strictly follow the parameters in the picture,
the short pulse width mode is 50~280us
long pulse. Wide mode 110us~1.2ms
low frequency pulse mode, the lowest is 4-5hz, the highest is 128hz,
the normal mode is the lowest 92hz, the highest is 2.2khz (in this mode, if the pulse width and frequency are too high at the same time, it will become a cw continuous wave, worry about bursting the tube)
This is the same model Video of circuit making (although not much views [sad])
