I just made this setup this morning with a 2sc3320 transistor and it worked great! Thank you! I am going to link to your video in my description because, well, you made it all happen. Thanks very much :)

Great video. Clearest I have seen yet on how to turn flybacks into usable powersupplies

Any reason why the diode gets really hot but the transistor is barely warm? Its not working and i get sparks on the battery contact when i connect it to my 18v drill battery, but no arcs

This is the Absolutely Best Info/Instruction i've seen so far i think. Because He is the ONLY one i have seen here on youtube who explains the effect that different windings(Feedback/Primary) will do and what you should do to protect the Transistor, and so on.. But when i Replicated it it didnt work. i wound both Feedback And Primary ClockWise but it didn't work, as i said, so i switched the connections of the primary, and then it worked Great. I REALLY wish there was A LOT more videos out here that Explains WHY it's better with a "perfect" Air-Gap between the Cores of a Flyback Transformer.. And for those who maybe destroyed the original one, how to make a new better one, for Hv stuff.. And so on. MAybe i'm just like that as a person. Sorry for my Grammar/Spelling,, Im from Sweden

Thanks for the video!

My Flyback worked like a charm ✨️ Thanks for the simple explanation. It took me less than an hour to make... my transistor needs a bigger heatsink though. (Gets fairly warm) Other than that EXCELLENT!!! I produced 2 inch bright purple streamers using just a 12 volt lipo battery. I'll probably need a radiation scan later 🤣. Tons of ozone. Thanks again 👍🏽👍🏽👍🏽💗

You can put a capacitor between the collector and emitter so the transistor doesn't heat up very fast and it also prevents it from killing the transistor from voltage spikes but you will be getting a lot of heat on the 22 ohm resistor

Really nice work man!

This is pretty cool flyback driver. I really like the circuit and your way to prevent damaging the flyback transformer (heatshrink tubing and candle wax!). Anyway, cool project as always and keep up good work.

the circuit and the diagram are not the same, the diode is in a different place. the diagram shows it between emitter and the midpoint of the voltage divider. but in the actual circuit its between emitter and collector of the transistor.

yes, the diagram is wrong, the diode has to be from emitter to collector to protect the transistor from the voltage peaks of the coil.

Hi! Great video, I really enjoy your content. I've read that you use a motor cycle battery at 6-10 amps for the power supply. Could I also just hook up any old car/moped/motor cycle battery to the circuit? I realize this is a lot of power, would it be lethal to be shocked by the output electricity or any electricity from the circuit/battery?

@ludicscience

yes you can use a larger battery, power will not increase, the circuit takes the amps that it needs. a larger battery will not pump more amps.

which flyback transformer did you use..? I tried but it's not working and th resistance of coil are also not same as you have shown.

Does it use a lot of current to drive?

hi i build this but im getting very small arcs(current drawn from my psu 0.2amp), can it be because of i used 253 ohm and 47 ohm resistors instead of 220 and 22 ones? i did the calculations and the voltage divider should give almost the same values. please help :(

Thanks for the tutorial. Ive wound two separate flybacks with both sets of windings as set out. When i applied voltage from two 18650 batteries (about 8 volts fully charged) to the 12-24 volt flyback the tip35c burnt out. Is this to be expected? Also i used .8 mm enamel wire for both windings on both flybacks, then encased the coils in epoxy. Is there an optimal gauge of wire to use? I'm drawing an arc of about 20-25 mm on the 12 volt flyback - up to 35 mm when shrouded with argon gas! Thanks once again for the video, the project was fun to build and I've learned so much.

Hello sir, Can we use CFL circuit to drive ( OLD B&W TV, disc shape) of flyback transformer.

Works fine . I had a spark at 4 volts. And from an homemade high voltage probe I red 2 Kv and with a 12 volts dc 20 Kv. Does that make sense?

It works great! Only after burning some transistors (if you are a beginner)

Can the inner primary and feedback be used instead of separate windings?

can you hook up the outputs of multiple flybacks in parallel to increase the output or will it smoke something? I have done this with neon sign transformers.

Thanks so much for your videos! You obviously know a lot about what you're doing. I was trying to replicate your circuit (the physical circuit because I read that the schematic was wrong) and the weirdest thing happened. I'm using a PC power supply that delivers 22A and 12V and when I first powered it on I got an arc for a split second and then the wires coming from the PC power supply started smoking. I then went back and checked my TIP35C and found out that the circuit fried it because there was continuity without a drop between pins 2 and 3. Any ideas? I don't want to keep on blowing my TIP35C's. Thanks in advance for your help!

Use the original transformer Primary winding. in conjunction with a power switching Transistor such as a Bu508 and about 80 volts Ht. Use an aux winding on the Transformer for the Feedback or wind one with about 8 turns. You should get about 25 KV.

can we use lite the electrical bulb? i how many amp in it?

When I connected them, since mine doesn't work with the method in another video.... I tried them one by one, and when I connected them the pins made arcs between each other and (my flyback is with an internal capacitor) they charged the capacitor. What is your opinion???

Hey dude, I know you texted this a really long time ago but if you yourself do not know then you show not be touching a high voltage transformers, no offense my man but if you dont instantainously know this that means you have no experience and so should not be messing with this until you understand your theory. Im sure now though you are well experienced. My point what if this video was fake? or what if it gave the wrong info? And you clearly wont know. So youll get hurt and also possibly die too.

Why flyback curcuit built according your instructions uses only about 2 A though the 12V supply battery can provide much higher cuurent? That is why, I think, the arc is so weak if compared to your case.

Can anybody help! I rigged up same circuit with 24 primary turns and 16 feedback turn and 12v as Supply but the primary winding started to burn... Do I need any extra component for reducing current?

Hullo. I attempted to recreate this circuit, with PC power supply wire for prim and feedback windings and c4106 for a transistor Resistors are: 3 in series for 213 Ohms and 3 in parallel for 24 Ohms. But when I plug it with 7.5V DC adapter, it does nothing and on 20V 3.25A laptop adapter it only emits some crackling sounds, completaly no arcing from HV+ output wire. Also my transistor gets very hot in 10-20 seconds, altough resistors remain cold. Are that power supply wires completely non-suitable for these windings, or is it that C4106 transistor doesn't fit for it? Or maybe I have damaged my flyback somehow, as I am sure I didn't mess up with circuit.
