My new ZVS driver

I've built this ZVS driver and it stays calm like a rock when it runs on 300w.

Why is the arc white?

It's just a low-pressure air, it was purple for a moment and then it turned white.

Sorry for the video quality, but the phone was unusable because of the EMI.

First SSTC attempt

It's just the simplest slayer exciter with IRLZ44N running on 20V 2A.

The resonance frequency is 530kHz.

Finaly at home after 14 days electronic detox (vacation)

I missed my oscilloscope.

Upgraded 300w ZVS flyback SGTC first run

I upgraded the capacitor from Leyden jar to 32kV 8nF MMC bank. Now the whole circuit fits into the base and the sparks are bigger.

I wanted to achieve exactly the best resonance and light up wirelessly some bulbs and a high-pressure mercury lamp but my dad made me stop because it was too loud so maybe later.

Finaly, after 1250 turns...

I thought my hands will die. I used 0.15 mm wire from microwave oven fan.

My secondary coil 😭

After I finally finshed winding I dropped it on some sharp corner.

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.
