I built this on a breadboard. I strongly recommend no one else does.  EMF voltage spikes from the blocking oscillator on the left that don't destroy the Transistor or the batteries get stepped up to between 100 to 900V DC. Ten stage Cockcroft-Walton cascade then increases this to God knows what.

I managed to throw a spark 6mm from the output (blue) as well as some decent plasma corona, before I started seeing arcs between the diodes, smoke, and gave myself a few decent shocks. Don't build this.  Caps bigger than a few pf will hold enough energy to kill you instantly, even with the source disconnected.  After 3 stages the volts will be high enough to start jumping across veroboard tracks, and above 8 stages it'll leap breadboard holes easily.

The simulation is fun to run though, and also tests how much CPU load your phone can  handle.

But how does dc voltage is stepped up with transfomer??

faceblast

10 years ago

it's not DC, the first transformer is a chopper circuit. The second steps it up.

Okay this looks nice but it shows only 100v at the the output. Im no expert but a 100 v arent as merely enough to make a spark let alone 0.6mm while for 1cm spark 20000v are needed. I think maybe E.C. fault?

I should learn to read the comments first. I put it to the 1sec count and my phone froze for a bit. Kinda awesome.

May have to try tweeking this - maybe try switching the input with a multivibrator with a variable period.

Probably just never got around to commenting. I doubt someone with enough equipment to make one of these would also be careless enough to really injure themselves. Not everyone has 1:20 transformers lying around.

rbrtkurtz

9 years ago

I disagree with most of that. "Someone with enough equipment..." It's just diodes, 102 caps, two transformers, and a breadboard. Sure, not everybody has a 1:20 transformer on hand (the one I have that is close is more like 1:18), but they're easy to get. I'd have to order more caps because I think I only have about 5 102s on hand (maybe not enough of any one diode, either), but an idiot like myself could easily build this. Should I? Do I need to? Will I? Hell no! Anyhow, noobs, hobbyists, amateurs, etc., are blowing up components all the time trying to build stuff they don't fully understand. Hell, I blew up all kinds of stuff when I started learning.

faceblast

actually it works really well with a 1:1 common mode choke. best results so far have been on a 2x 30 turns on a 30mm toroid

faceblast

also the diodes have to be fast recovery

Mamish

Re: hurz. Valid point, but I was talking more about personal safety than component safety. I'd bet most people with a half-decent inventory have at least some awareness of HV safety or at least the risk involved. I never said they wouldn't destroy all their parts; I still lose MOSFETs to the occasional brainfart these days. No serious injuries yet though.

LoL .. Don't build? Probably a good idea but good ideas never stopped me. I would build this point to point and submerge it in oil or wax though, that should take care of diodes sparking and cool it a bit. Current regulation would be good to. Breadboards aren't meant for high voltage. Nice job on the circuit.
