Best Ne555 Flyback Driver! Step by Step (easy)

[@Epsicronics]

can we just apprecite for a moment how good this guy's ptp soldering is?

[@Buzzhumma]

Use the highest heat setting and tin both parts first. Then put them together and drop a dribble of solder onto the part without touching the iron to the part

[@Epsicronics]

[@NITESCIENTIST]

Update: I figured it out. I adjusted the primary windings to 9 turns, and the performance far exceeds even what you displayed in the video. Thank you so very much for this tutorial. I deeply appreciate it.

[@f.a3202]

could you please tell the max and nominal current consumption?

[@NITESCIENTIST]

@@f.a3202 It draws current and begins working almost immediately, at around half power, it draws around 1.3 amps. My equipment isn't sensitive enough to be anymore accurate than that, and I don't want to push it past half power because I already blew the circuit 3 times.

[@NITESCIENTIST]

@Mallu boy just wind it yourself

[@NITESCIENTIST]

@Mallu boy I honestly just used 18 gauge insulated wire. 9 turns is great, 7 will fry your mosfet.

[@NITESCIENTIST]

@Mallu boy The arcs I can get out of it are approximately 40mm to 50mm at half power.

[@MasterIvo]

the primary is switched on the low side by the mosfet, this will produce positive inductive spikes. those could kill the mosfet. better capture that energy in a cap for reuse.

[@Headbutter-Lettuce90]

Nope that wont work well, paralleling a cap and the primary will create a resonant tank circuit, its better to use a flyback diode

[@DolezalPetr]

@@Headbutter-Lettuce90 you use a different topology to achieve better results with storing energy in a capacitor, I think that is what he meant

[@Headbutter-Lettuce90]

@@DolezalPetr Oh i guess i was wrong

[@Headbutter-Lettuce90]

@@DolezalPetr no he said that the primary strikes with a current peak

[@DolezalPetr]

@@Headbutter-Lettuce90 yeah that is why a different topology is better where you can reuse it to charge capacitors

[@stealhty1]

Back in the 50's and 60's elements where solder just like so , in the absence of circuit plates

[@NITESCIENTIST]

I just finished wiring and testing this driver, and it works perfectly. I am, however, not getting the kind of performance that was demonstrated in the video. My arcs, at max power, jump at right around 8mm. I need at least a 13mm arc to properly test a prototype. I suspect my transformer is to blame, but any input would be greatly appreciated. Thank you for the excellent tutorial.

[@constantinjitariu1439]

Transformer it is my transformer makes arcs that jup over 40mm

[@yiannisyiannis]

Yes! Thats because it depejds on the tranformer... not all flybacks are the same... thos small changes on each transformer can have a critical change to you circuit performance....

[@devilssongs530]

Same pinch, my flyback_eth_crt transfomer jumps the plasma_arc between its own pin when i apply more voltage, what a creek. Now i am thinking to make custom secondary winding for that.

[@paramitadas7545]

You are using a bench-power supply here, which is limiting you're current flow. So if you use a battery, instead of power supply, as there will be no more current limitation the arcs whic are thin and blue in color currently, will be thick and white hot. Hence it will give better arcs. But the length of the arc will not get affected as it depends on the voltage. Now I might be wrong about this whole thing, but I think I am not wrong. Feel free to correct me if I am wrong.

[@dalenassar9152]

I think your 555-based circuit can be greatly simplified, as the 555 output is a push-pull half-bridge. Do you have any suggestions on driving a ferrite core to get out around 1kv @ a couple amps?? THANKS MUCH FOR THE GREAT VIDEO!!!!

[@Ryan-lu9km]

Can I power this driver with two 9 volt batteries (18v), instead of a power supply ? How much current does it draw ?

[@yiannisyiannis]

Hello there... I made the circuit and when I power it I can hear the frequency from the transformer but I dont dee any sparks... also when I move the pot the frequencey that i hear also changes.. no sparks tho... I am powring it from a 12 v battery.. is this the reason why it does not work?

[@styrishrodrigues]

Why didn't you add Zener diode or snubber across Irfp460?

[@josegante6982]

because the circuit change the polarity.. if you put a diode.. No arcs..

[@Jonodrew1286]

Bloody awesome - I did similar with CCFL lamp driver - with a big swirl 10’000 hour lamp on it - the cap burnt out so I took it apart and repurposed it for flyback usage - insane arcs but not really for flyback use and can get hot with prolonged usage…… That a neat circuit and construction is floorless - I have done a few ZVS circuits like that too… 👌👌👌👍👍

[@_jonathanfilip_]

I made a circuit very similar to this just minus the 3904 and 3906. Does any one know why I get so much ringing in my circuit??

[@RODALCO2007]

Would it not be a good idea to put a fast diode UF4007 across the IRFP450 to protect the Mosfet?

[@Teslaundmehr]

I think this is not necessay because they have an internal diode 👍🏼

[@Teslaundmehr]

A TVS Diode would be better

[@RODALCO2007]

@@Teslaundmehr Ok, thanks for your reply. Just checked the IRFP450 datasheet and it has an internal diode.

[@judlex7300]

Hello bro, could you tell me what i did wrong? Everytime i do this circuit my mosfet gets very hot and gets killed i have a good heatsink and fan cooling. But i think thats becuase i use external winding instead internal one

@@CC-xc1xq It was vintage flyback from the good ol' days (monochrome TV) where the required voltage was higher, hence the ratio of the transformer.

@@panjak323 I'm assuming you meant to say 30 mm, as there is no way you generated nearly 900 kV with a flyback transformer, assuming 30 kV per cm air gap

@@apo_chromatic 1 MV is enough to cover 1m distance and even more. Depends on how you build up the spark, if you ionize the air first, the break down voltage drops to 2-10kV/cm. For example my TC had been able to output 1,7m sparks, but output voltage was about 1MV only (assuming 5000V on primary resonant circuit with 1:200 ratio) .

[@Teslaundmehr]

Ever hear of a video description?? ;D

[@firstnamehidden6514]

Yes, video descriptions are slow in conveying construction information and do not give the builder the knowledge of exactly what he is trying to build at at first glance. Like drawing pictures to communicate when you don't know the common spoken language. The results include unnecessary temporal depletion, aka time wasted. So you appear to be an advocate for wasting people's time for personal gain, or a far worse crime in electronic engineering. Not being able to work with a circuit diagram.
