This machine is a beast. Will look good in my lounge room or doing demos at the local high school.
5 foot sparks Might clear the air of corona virus. I wonder if it likes ozone Laughing

This is the oldie tuned down a bit so it would work in the shed.
Sparks are about 26 inches long and hit the roof.

Picked up a small made in China Tesla about two years ago and never got round to unpacking it, so now that I am back in a Tesla mood Thought I would check it out..
It is Okay and quality is quite good. Tossed it together and gave it a run.

Is fine and produces approx 10 inch discharges. can also play music if you feed it with square wave audio.

Bummer! Just after that last pic the power supply MOSFETS decided to blow.

All fixed now. Very Happy Although the power supply input fuse is blowing on a bit too regular basis when the unit is running full power. GRRRRRRR .Might have ta stick a 6 inch nail in the fuse holder. affraid Laughing Laughing

Well worth watching.
My little machines power supply has smoked itself once too often (mosfets blew their guts out, literally) and is now in the fix it later bin. Mad
  I cranked the input volts up a bit and things worked fine in low power selection but when i selected high power the mosfets disagreed and said stuff this I'm outa here. Laughing

This son of a gun bites.
Won't be lighting up any globes in my gob with this one.  pale
Held an earth wire up to the discharge load and the spark bypassed the earth and nailed me good. Spark here is about 11.5 inches. May not be the 26 inch discharges that my old original not so well tuned tesla could dish out but not bad for what this little one is.

Interesting how some of the discharges can start out quite zig zaggy and then become be fairly  straight ish.

Place a glass jar over the top load and bright orange flashes appear along the plasma flows

Just found out that if you spray a bit of hair spray into the jar and up-end it over the top load and fire the tesla the jar launches like a rocket. affraid lol!
I knew it would do that, I just wanted to see it. Laughing

I recall when i was 16 or 17 and had built my first tesla coil I rigged up a setup so I could put hydrogen into a large plastic bottle. I made the hydrogen using a high school science experiment set up . Screwed a spark plug into the bottle lid and connected the tesla output to the spk plug and fired the tesla and Walla! a hydrogen bomb that worked very well. Mum was not happy and I never did that again. affraid
