MMC bank question

Do you think that those capacitors are good option for 300w SGTC Powered by flyback transformer with ZVS driver?

My plan is to use 2 paralel rows with 15 of them in series. This should have 30kV DC and 6.26nF. 30 of R75UN247050H3J cost 474 CZK (around 22.3USD) on TME, I think that It's a good price.

I want to use 15 10MOhm, 3.5kV, 0.5w resistors in paralel with each pair of capacitors, Is it right?

Flyback arcs with cactus electrode

I just used a cactus leaf as a electrode and it made those beautiful orange arcs.

HV source was a flyback driven by modified temu ZVS driver (IRFP064N 》IRFP250N) running on 25V 10A max.

Arduino survived...

The copper plate was connected by some screw in power suply and this happened by mistake.

Small pulse transformer for stun gun.

I made this pulse transformer from ferite core from radio, wire from microwave fan and 3D printed coil. I made it for 1.5kV pulse input from spark gap, but I haven't finishe 1.5kV power suply, so I tested it with arduino on 70kHZ and 3% duty cycle and this happend...

Pls don't hate my english if it's bad.
