Any chance you could comment on what power transistor you used? It wasn't labeled in your schematic

Very nice explanation! I'm really surprised that the PWM 555 was ok with being turned on/off via Vcc on the timer itself. I would have probably expected the PWM signal to be always on, always modulating, and then the latch just controls some sort of "enable" on the base of the solenoid mosfet. I suppose by switching the PWM timer on/off then you've eliminated the need for a switching transistor on the mosfet base. Am I missing something otherwise obvious on that? Quite clever! Also, the rpm of your engine is pretty low, but do you know what frequency range the PWM is switching at? Very nice engine and excellent video explanation. Thanks a lot!

I bought one like this 2 years ago and I still haven't got it running. Think it helps if you have a Physics degree 😂

It would have helped the viewers if you showed how to connect the equipment to the Tesla coils. But thank you for the demonstration.

Os raios saindo da bobina são bonitos mas, é um grande desperdício de eletricidade, ele poderia ajustar a bobina para transmitir a energia para outra conformo Nikola Tesla explica em suas patentes...

Wow, are you still building these?

Is it possible to achieve the same result using 4 microwave transformers as HV source?

This is amazing method I think it could be used to test the surface resonance of any conductive freestanding object pretty awesome!!!

Beautiful running engine! Is it a push pull style? I only ask because of the dual pickups. Thanks!

How did Tesla do this when he didn't have any of these tools? Or did he?

Hi, thanks for sharing. but i have to connect both negative end of tuner & the oscilloscope in order to get a visible sine wave. any advise?

Arc to the strike ring triggered sequence of events causing flashover. Most likely several streamers terminating in the air half way between the toroid and the ring deposited space charge that was attracted to the coil winding insulation. When final streamer reached the ring these charges on the outer surface and charges of the winding formed a "capacitor" that was discharged when arc got close enough. The sequence quickly repeats and region of discharge (due to both dielectric stress and thermic stress) grows which caused the flash over. Any case the coil was operating on the edge of flashover-big toroid without breakout point (voltage peaks certainly over 700 kV) and not much imbalance is required for this to happen. "Overcoupling causes" are generally overrated. Even with very small coupling one can trigger racing sparks/flashover if the energy is to high while big smooth toroid is installed on relatively thin secondary.

Thank you for sharing this!

Gorgeous fun boys! <3

What are those white stripes moving downward ? they appear only when the power is high enough but you can see them in the entire video. (0:46 they are right in the middle)

Hi, im building a tesla coil and need the spark gap to fire at 40khz. Is there a way i can measure the bps/frequency accurately without damage to the device?

What does it sound like?

Would it be possible to obtain a schematic of the electronics?

Hello I’m looking to buy one if you can please help me +36705979994

mega mate...............

superb, thank you for sharing

Very cool and what is the music please

Great !!!

Very useful info not found anywhere else. Just did not understand the balancing with the pencil marks. Thank you for taking the time.

Been nice to see the actual way you generated the timing pulse

beautiful thanks

How much watt?

It looks alive.

It's amazing.....

Very nice running of legendary engine. Just like heart beat. But too short video.

Pode ser uma fonte simples mesmo com lm317

I love steampunk! Thanks!

Hi... Please excuse my ignorance but could you tell me what value capacitor bank I should use when finding the resonant frequency of the primary? I was under the impression that the resonance changes due to capacitance value... is this correct? Thank you for a great video as I can see it has helped many others...

hi i,m sorry to be a pest , i realise a plan is a bit to much to ask . i understand most of how your power feed works but i would really appreciate it if you could tell me if the dog clutch is available to buy or do you need to make one, at first i thought it was a worm . hope you can advise me thanks john

hi follytowers could you put me on the right path for making the power feed or i,ll be very happy to pay for some basic plan for the worm and wheel ratio etc cheers john

nice job love to copy what you have done did you have any trouble with excess backlash

That’s epic boys.

I like that you use industrial and other high quality components. I can tell you’ve been around and seen some cool things

hello, please give a circuit [email protected]

If you want a single streamer try a sphere top load, ive seen arcs climb straight up and just stand there its real spooky because they dont retract immediately

Even with BP not immune to rail/ball strikes

Its a beast.

Your coil loves that topload. I think I might try running without a breakout point today.

AuNatural. Thats how I like em'. So got the coil set back up and will be running in 1.5 hrs. Ive recruited a cameragirl so mabye I will get some good video. Appreciate the uploads, Phil!

That was a huge flashover. As soon as the racing spark appeared which happened just after the coil latched onto that strike ring it would have detuned the coil as it covered 70 percent of the length of the secondary which caused the second spark from ringing which then disrupted the field around the toroid and as the bolt off the top was white hot and very close it got pulled in. What im curious about is how well is that strike rail grounded. it being under plastic might have cause dielectric seperation of enough charge to reflect some of the energy being pumped from the toroid to the strike rail back up the arc and then at 1:51 look at the knee of the toroid arc and look at the wave wiggle in the secondary arc. The shape suggests that the two arcs were field coupled to an extent and that allowed the jump to the bottom of the secondary arc from the toroid arc by the reflected charge. Right before the jump to the secondary the flashover resembles from midpoint up the shape of the toriod arc parallel to it even with the hook at the to p of the flashover arc although somewhat shorter in scale. just some speculation. That is how you power arc the secondary. I never had mine do anything that crazy. It was still putting out small streamers from the toroid as it was cooking itself. aVery white hot arcs. Beautiful. I might run my coil tonight as it is 40 degrees out and weather forcast is good. Gonna go set it back up and wire my sparkgap back in. Hopefully the revamp is better than before and I can crank it up. Have a good day.

this is an amazing coil. Absolutely Philnominal!

Cool engine
