hey. i have a flyback and this is what the pins are: col. , b+, 25v, 12v, 8v, 180v, abl, gnd., afc., and heater 10. there are 2 wires coming out of the side and the big ont that in a tv goes to the crt.
could u plz tell me witch ones to hook up to what to do somthing like this??
Hahaha ("hot glued the .frikkin crap out of it") that comment crack me up mate!! Ya have to glue them up don't ya mate. I once didn't and ow my god it went mad with arcing over to all the pins lol. Well I was giving it 36 volts!! I always try not to destroy my flybacks as I love-em!!Ya videos are awsome. Keep up the good work and be safe! ;)
Hey what's ya name by the way?? It's not junior lol Id kill my parents if thay did that to me lol
@high1voltage1rules All of my decent flybacks are dead, I am left with crap now. I wound my own, now, with way thick wire, but with an excessive amount of power to my new ZVS, it pulls a good 5 inch arc about 2/5" to 1/2" thick. I need to get some thinner magnet wire, and wind one for higher voltage, so the arcs can stretch farther. My real name is Salvatore. And whats your name again? I know you mentioned it before. Thanks
the mosfet heats up when you are not arching because the power is building up and not discharging in another form of energy. so the excess energy is in the form of mosfet heat. GOOD JOB though you should probably hold the black wire with a long piece of wood because even though the wire is insulated, at that high of a voltage the wire cover is not even an insulator anymore
@AddColorsToYourLife That makes a lot of sense! Thanks for pointing it out why the mosfet heats. Holding the wire is not really, but would certainly hurt if it burnt through the insulation. I only did that in this video, I used a chicken stick after.
Hey mate thats the best 555 driver iv seen i fink lol your camera seems to make the arcs look fake lol obviously they are not fake but its funny how the cam makes it look that way and it looks cool how theres corona on the lead your holding btw ive made a 2n3055 feedback flyback driver but im just looking for the flyback could you give me some tips on how to get the longest life out of it possible
@jake3085 Thanks, well, there was a lot of corona in real life, but the camera sure did enhance that pretty well. And that is with a UV filter. Maybe a polarizer filter would stop that instead. Not that it bothers me though. To be honest, I have never made a 2n3055 feedback driver. The closest I ever made was by using a TIP120, which worked well up to 24V at a low current. There is no real methods of making it last longer that I know of, besides using superior cooling.
1/1k + 1/2.2k = 1/R or 685 ohms When adding resistors in parallel you add them as inverse. When you add them in series you just add their values together.
@blackmesa25 I have not collected any in a long time. I have not been able to go garbage picking lately. Every flyback is different, they like different frequencies, have different current and voltage outputs, some have capacitors, ect. When I ever see one in the trash, I am sure I will rip it apart and leave a little surprise on the victims curb lol
I should make a video of my collection. What I should do, is wind my own someday since I keep killing them.
Hey! I've already killed 3 555's! What could I do to protect my 555? Should I use diodesIm running it at 12V and max 1.4A, so I dont think the input power is the problem. Thank you!
Adding a capacitor helps with self-oscillant driver too , but the issue is that you use max power even when not drawing arcs , do you have same issue with 555 driver?
@lo9765 Yes, the capacitors are needed in the self-oscillant driver (ZVS) for it to work correctly otherwise there will be pretty much no output. On the ZVS, the driver uses very little power when there is no load, but when you draw an arc, that is when it sucks up power. With my 555 driver it seems to draw the same power when or when not arcing, which may be why the mosfets heat so badly in most cases.
@juniortore1 no , i'm not using zvs , i'm using simple transistor oscillator with feedback , using 2x 13007 high voltage npn power transistors wired in parallel , a capacitor in parallel with primary winding and one in parallel with feedback resistor , using 35 volts power supply , which under it drops to a lot lower voltage , i get about 60-70 watt output , with almost white arcs
@juniortore1 the only problem i have is that it draws max current even without load with the risk of overheating rectifier of the power supply, and i get ton of heat on transistors too , but that is normal , i have to use a fan to keep them cool , or current will drop very fast , capacitors tends to heat up too
Hey man, how much current are you pulling from there? I've already connected it without a res cap and an inductor directly to the supply (with a12v reg. for the 555)
Do you think it is possible to provide about 500w with that driver?
@dzdice At 36 volts I was drawing about 2-8 amps. In my opinion, even if resonant do not input over 24 volts, because if anything fails your driver is trash, and possibly your power supply. It is possible to do 500W but the arcs will probably be very crappy if your mosfet does not immediately explode. In my opinion, make a half bridge or ZVS driver and you can draw much bigger arcs with much less input and driver heat and driver stability. (see later zvs videos I made)
@ciprianwiner no problem, hopefully it helps, also, that little inductor transformer on the in series with the input certainly helped a bit, so try some work with the inductors in series with the mosfet-flyback-positive voltage
@juniortore1 ok i will try to put an inductor choke in series with the mosfet-flyback-positive voltage(i got a pretty good one from my old monitor) :D
@juniortore1 no, take a small transistor to drive a couple 2n3055s. 2n3055 has 15A and 60v (i think) so the only thing you will have to wory about i inductive kickback frying your npn's. i just ordered a couple high power "IR" npn's that can take 30A and 200v. this should take care of any inductive kickback and drive a flyback without warming
The mosfet runs cooler while arcing because when you have no arc, nothing is dissipating the energy and it ends up reflecting back to the mosfet. If you scope the drain pin you will see the spikes get much higher with no arc. If not for the avalanche ability of the mosfet, it would just blow whenever that happened.
well if the tv your working with has the flyback on a seperate cicuit board and not on the main board then you might be able to but otherwise my idk. the only reason i would use it streaght from the tv is because 98% of my projects involve building stuff without buying stuff because only cvs is within biking distance and theirs no way my mom would drive me for something like this. but ill find a way. also i do have a flyback seperate from a tv along with 2x 12 V batterys .
the mosfat heats up when not arcing because their is no dicharge which is like charging a battery without a smart charger and letting it run for longer than its safe charge zone and another is i would make my own capsitor with a glass jar because it will not heat up as much because its just salt water in a jar. and 1 more thing
i know making a 555 driver for it makes big arcs but i thing u can use it straite off the tv. all youn have to do is ground 1 wire to the metal frame and then 2 the FBT
@juniortore1 also when i said you can run it directly off the tv... well you can but not for long amounts of time and the reason they would fry is because insted of creating the arcs aetween the glass part of the tv (i forgot what that is called) but you have to ground it and the flyback cant be connected on the main circuit board along with the other components. it has to be a tv where the flyback is seperate from the main board which then the flyback would likly be sitting behind the--
@08Kutt Just to let you know, I hate the IRFP250. Only reason I re4ally used it is because it is cheap and can do 30 amps. From now on, I will use different, newer, better designed mosfets or IGBTs
@08Kutt Dude, use a voltage regulator! or power the 555 timer with a different 12 volt transformer, combine the negative wire of the 12 volt to the higher voltage negative. In simple terms, go with the 12 volt regulator since its hard to explain the other method
@08Kutt Why schematics? I explained it good enough didnt I? Just average 555 flyabck driver, with a .22uF capacitor across the flybacks primary. And for the inductor, its not needed, but I found it to help keep the mosfet even cooler than it was. That just went in series with the + and the flybacks primary to mosfet drain
@mgregggphone I am working on a good 555 board. I will make a video of it shortly. It is on a solder type breadboard, has a 10k 25 turn trimmer pot for duty cycle, and a 50k 25 turn pot for frequency. The frequency is set by a .01uF capacitor. This board has the npn/pnp pair for more power. I have not finished the connections on it, and want to get screw terminal sockets for the input. I plan to test it this weekend
i tried using a 0.22uF 400v capacitor and some random inductor but i ended up stuffing everything up so it doesn't work so i will remake it without resonance stuff. instead, i will use something 3 12v SLA batteries (with the 555 regulated) to get a massive output.
HOLY SHIT BRO! I can a crap load of corona hissing around your fingers when you hold the black wire. This kinda could be a sign hat the insulation may fail sooner or later and you may get hit with nasty HF burns! Ouchies! Maybe you should probably use a bit of HV cable cut off the flyback power out and you should solder that onto the existing black wire. Still, awesome video! I love that! I have so go to do that when I get my IRFP250 MOSFET's in a weeks time
I love that "How do I do that? Well, I don't know how I do it. It just works that way." bit. :p :) ~ I've got *so* many questions about this vid. I'll have to PM you, even if you don't (or can't) answer the questions.
@TheTacoActOf1763 Bro, you honestly have NO idea what high voltage electronics is like! Please keep your nasty insults to yourself and don't let them out. juniortore1 does not deserve all of that crap you are giving him. Go away. Now. Please
If you saw my latest flyback video, my arcs shot off about as far as yours, but for some reason mine drew a shit ton! But awesome arcs never the less!
Now see, if you had some Pots instead of resistors, there's a good chance you could get better yet arcs =) Also, that ferrite transformer you used as a ...Ballast? It's a SMPS transformer that powers the whole board. Usually 300W or so, and ranges from id guess 5V to 24+
@PhxSt0rmz Well, I am not ripping this mess apart. Ill try that when my breadboards arrive.
And its not only acing as a ballast, something with inductance is going on. Without it, my mosfet heats badly (still not like before butttt...) And when I wire it up, the arcs are noticeably bigger on 12 volts.
The MOSFET stays cool because the impulse that normally feeds the arc is being wasted in the MOSFET's diode that protects it from over voltage and damage ... some parallel diodes could help it , idk for sure so maybe someone will explain it better but i know MOSFETs don't like spikes from transformers. But wow! those look great for 555, i've actually never made anything with 555 that wasn't just making heat xD or horrible noise as it was messed from some interference ...
@filipkof Ya, the 555 flyback driver normally makes a LOT of mosfet heating. I have had 2x IRFP250 mosfets die at 12 volts from overheating. And yep, thats what I thought. Also, this goes with the concept of getting rid of kickback, but the capacitors may help smooth that.

@HazzWold1993 Well, I think the inductor plays a role here, I will make a schematic of it in another video when I buy or find the proper capacitors.

If you saw my latest flyback video, my arcs shot off about as far as yours, but for some reason mine drew a shit ton! But awesome arcs never the less!

@zker666 Ya, I saw it. Well, now to try to mess with capacitors :D
Here, it draws 8 amps or so, but the mosfet doesn't heat. As to without the capacitors, it uses the same amps, but it heats BAD

Now see, if you had some Pots instead of resistors, there's a good chance you could get better yet arcs =) Also, that ferrite transformer you used as a ...Ballast? It's a SMPS transformer that powers the whole board. Usually 300W or so, and ranges from id guess 5V to 24+

@PhxSt0rmz Well, I am not ripping this mess apart. Ill try that when my breadboards arrive.
And its not only acing as a ballast, something with inductance is going on. Without it, my mosfet heats badly (still not like before butttt...) And when I wire it up, the arcs are noticeably bigger on 12 volts.

That is one nice driver!
But dude, use a chicken stick, there was visible corona to your hand!

@holycrapapie Thanks. Ill build a mini PVC one sometime.

The MOSFET stays cool because the impulse that normally feeds the arc is being wasted in the MOSFET's diode that protects it from over voltage and damage ... some parallel diodes could help it , idk for sure so maybe someone will explain it better but i know MOSFETs don't like spikes from transformers. But wow! those look great for 555, i've actually never made anything with 555 that wasn't just making heat xD or horrible noise as it was messed from some interference ...

@filipkof Ya, the 555 flyback driver normally makes a LOT of mosfet heating. I have had 2x IRFP250 mosfets die at 12 volts from overheating. And yep, thats what I thought. Also, this goes with the concept of getting rid of kickback, but the capacitors may help smooth that.
