Joule Ringer!

[xee2]

Do you have a more recent flyback cvircuit you could post ?

Thanks

FRC

I have not made any new Joule ringer circuits. This is a basic flyback circuit.

You had your excitter powering a Joule ringer. Do you now have the Joule ringer powering the excitter? Or is this an excitter powered by a capacitor? The lowest current that I can get my excitter to work at is about 20 ma. You must have your excitter working at a much lower current. Congratulations.

Nah - the exciter is STILL powering the joule ringer. But, if i use 1AA in a phone charger to directly charge my 58000 uF capacitor that runs my joule ringer i can only get one CFL to work (and not one of the big 36W ones). If i use my exciter with 1AA in a charger, and connect the toroid to an AV plug which goes into my 58000 uF cap, then i can run lots of CFLs at once, and they ring for a long time afterwards when the battery is disconnected.

Try it Xee - i know you have an exciter and a flyback oscillator. Connect a top load (which is DISCONNECTED from the exciter secondary - mine just hangs on top of the secondary. If i connect it i lose resonance) to a couple of IN4148 diodes which connect to the power capacitor terminals of your flyback oscillator. Now add CFLs to the output of the flyback. Seems to me you can use any and as many as you like. Use a radio and LED AV plug to determine when the flyback ALSO reaches resonance (as the exciter does). And Bobs your mums brother. Id be really interested in your results.

The basic fuji circuit has 3 windings - a 15 turn clockwise, a 6 turn counterclockwise and the large winding of 1750 turns clockwise. The circuit works just like the Brovin/kacher or slayer ciruict so it finds its own resonance. The biggest key to getting the results Lasersaber is seeing is the transistor he's using not necessarily the coil. I've had success with an 850, 1100, 1400 and 1750 turn secondary, although I had problems with arcing on the 1400 and 1750. The transistor is the key to it's success or failure.

Well managed to fry the Fuji circuit. Will have to get another one. These seem to have a lot of potential. I think I know why I could not find xee2's flyback circuit, It was not here, it was posted at Overunity.com. Still learned a lot from the Fuji circuit and have a few salvageable parts from it. Hope the next one works out better.

After 1:25 no battery connected, its all just running off the cap. (Big, 58000 micF)

aaron,

thats nice that you have data/info of that fuji core

perhaps you might want to post those here?

I was also planning to make a "bigger" version of that fuji core

hints for coil winding

aaron5120,

try this:

if you have a spare -fuji- circuit/core to spare with, why not disassemble the core and count the number of turns for the primary(take note thats for 1.5V operation)... multiply # of turns to your desired input voltage, say 12V(x10T = 120T).. that would be the primary, and feedback...

as for the secondary (the one going to the FL, wind a thinner gauge magwire) and do some 1000+ turns, measure with an ohmmeter , same as the orig, about 200 ohms...


of course you could also wait for lasersabers reply

@Raff,
Thanks for your suggestions. I already have the data of number of turns and wire gauges of the Fuji trafo, what I don't know are the ideas Lasersaber got for winding the secondary in order to perform as per the designer wants. He has already wound a lot of them and got much experience. For instance, should I put teflon tapes around the winding every several layers to avoid arcing,etc... Nevertheless I appreciate whatever hints you guys have for winding the HV coils though.....

as for me, I dont think our area sells these fuji disposables. too bad, cant play with them

I love this joule ringer and i cant thank you all enough for leaving the interesting details for construction. I seem to be able to keep adding to the output as long as i stay on low input levels. If i try anything more than 6V it doesnt seem so easy to get the joule ringer to resonate, but with low power levels there is a lot this can do.

Here my latest build. 50v 9700uf.

@Lasersaber,
Hey Buddy, I already got the (ferrite and coil form) set from Surplus Sales.com, and are ready to wind the transformer of your J Ringer circuit. Any hints you can give me in order not to trash the magnet wires I am going to put into the coil( due to the HV sparks)? Thanks a lot for your help!
I got the flash circuit trafo,but it is too small,and it sparks and burns easily with a little bit of overvoltage at the input!

Do you have a schematic ? Video is kind of dark, would like to know what you mean by small flyback? Any help would be appreciated. Thanks

I was attempting to place leads from the CFL to the back of circuit board. I must have shorted something. Heard a big pop and that was it.

FRC,

how did you manage to fry it? I think from over voltage at input? or maybe -too low- inductance at primary (due to a higher input voltage)... that circuit is optimized for 1.5V operation.

if I remember correctly, those transistors are rated 20V @ 2A ... it can survive the dc voltage but not from spikes(few hundred volts) generated during switching..
