12V 555 Flyback driver

[2cooliobeans]

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??

[atelierpenguin]

@2cooliobeans I haven't any pin information of my FBT. (it's junk parts) That is a result of pin by pin try and errors.

[swedensy]

i dont see any schematic, what you talking about?

[swedensy]

Are you holding HV output cabel?

Im just trying to see wht pins are you using too.

[YoshiProgrammer]

Your circut.... ITS SO ORGANIZED!!!! MY EYES!!!! THEY BURN!!!!! XD

[kmncztms]

next to the ground pin, is a pin connected to a capacitor

Put a wire between the ground and capacitor pins.

And while approaching the hv out, it created loud white discharges ;D

Be careful though, it fucked my hands really bad when I let my guard down :S

[tyreza79]

you can build something to make this disk turn hell faster and creat more energy !!

do something ot hand cranck it !!! it wil be awsome !

[Masamuneblade7]

@tyreza79 Actually I was thinking something along those lines... I found that high voltages tend to make little effect on motors, I think its amps that drive the magnets... It sucks

[Masamuneblade7]

Hey penguin, I have the exact same transformer. I was messing with it earlier, I have in sequence 16 9-v batteries (My multimeter registers 141 volt output) But for some reason when I touch my two pins for the feedback on my transformer, I get a 1mm arc before contact... How does my 140v jump to 1kv through the feedback? That and for some reason when contact is made, I get pathetic sparks from the HV out up against the pinout...

[GearzVoNKod3]

My problem with this circuit is that sometimes I can hear a faint oscillation in the circuit somewhere, but when I connect the IRF510 nothing happens. When I connect the coil to the circuit, the 555 heats up really fast and the IRF510 stays cold, and the flyback does not get driven. What could be causing this?

[atelierpenguin]

@GearzVoNKod3 I didn't test any situation of drive. I can't understand where you insert the coil in your circuit.

[powermaks]

@GearzVoNKod3 the 555 is locking up on you. do you conect a capacitor between pin 5 and ground?

[RRdigy]

I have a problem. I think that i made the circuit for my flyback transformer right but theres somethin wrong-It gives out only 19 volts when i use a 9 volt battery! there are sparks but they are only about half a milimeter long. Why it doesn't make normal sparks and big volts?

[atelierpenguin]

@RRdigy Maybe 12V-1A or higher DC source is needed. or increase or decrease primary turns.

[kmncztms]

@RRdigy At first, I used the original windings, and I only got 250 volts. Then I made 2 of them myself (feedback and primary), and they worked fine. They made about 2 cm long sparks.

[powermaks]

@RRdigy check the polaraty. also tune the pots. (if you are using 5K pots over resisors) and try 12V 2A

[elettronicarusso06]

Ciao,mi fai avere lo schema, il disegno della piastrina,e l'elenco componenti del Tuo circuito? lo vorrei usare come prova eat dell' HR .

Grazie ancora e buona serata.

Many components. Why do it complicated when it goes easily.

[0903390901]

My FlyBack EASY scheme. transistor MJE13009.

[prototype9000]

i powered mine electromechanically

[juniortore1]

Funnnnn

[TheLightningStalker]

Try the circuit on my website. I've actually burned up several flyback transformers with it.

[plavins1]

2n3055 IS OK TOO .. check out my vid of my 2n3055 flyback driver.

[Dri0m]

@plavins1 hmm 2n3055 is weak because schematic making 20-50kHz, but maximal frequency of 2n3055 is 10kHz, so after a time it burns

[darrylportelli]

hey I have one of these flybacks...can they be used for high voltage experiments since normally, the old flybacks are used(which you can disassemble and rewind). if I can use this type of flyback, what is the pinout of the flyback or how do I find the pinout.

thanks

[atelierpenguin]

@darrylportelli Try all neighbors two pin for primary it's must be zero ohm DC.

I found such a blind process

[mik32526]

the arcs are fuzzy and stray because the circuit needs a few more amps

at that length with a few more amps arcs should be quite unless frequency is off a little

step up the mosfets and you got a beast!!!

good luck try makeing some capacitors in a month or so look back to my channel for instructions on how

[panzuman]

whats the difference between an ne555 and a ks555?

[08Kutt]

12V AC?

[zker666]

12v DC in about 20kV out

[LoneOarman]

those pins work for me also, but are they primary coil. I'm using the other side for primary, the pin one as neg and three and hot.

[rroge5]

how do you know which 2 pins your going to put the input into?. ive tried searching hard to figure this out. but the internet doesnt contain enough info ,

[anorwood84]

Get out your ohm meter and start searching. There are usually only 2 pins for the primary and they are right next to each other. You will find them by testing with an ohm meter, they have a resistance of about 0.7Ohm.

[LoneOarman]

You have to test to find the layout with a 9v battery. It's all over the web, and you do not need a 555, just a 47mf capacitor and a single audio transistor.

[holycrapapie]

@rroge5

The primary pins on a FB transformer are usually a bit further away from the other pins.

[rroge5]

ive been wondering about how you identify them for like 2 years! finally someone tells me something usefull., >.> this is like when i used to think 5 band resistors were useless, but 1 of the bands is furhter away from the other 4.

[holycrapapie]

@rroge5

Always happy to help a fellow DIYer!

[LPFthings]

That pin up the top you were zapping is the inbuilt high voltage capacitor. If you connect that one to the ground pin , then arc to it you will get big loud sparks :D

[sorefame123]

Can you use normal cables? Don't you need to use High Voltage ones?

[atelierpenguin]

Normal one is OK

[ubuntupokemoninc]

@sorefame123

normal is ok if you like shocks, low voltage goes threw the insulation, i am speaking from experience

[ibrahim01656]

how did you make your circuit send me

[predator2036]

you dont any driver too the flyback just use the tv circuit board but like starting a tv without a cathode ray tube!

[hbenders3356]

schematic is in the details

[zezimashock]

yea i saw it to late -_-

[jovicakluk]

check mine out its much more powerful

[zezimashock]

shematic?
