Joule Ringer!

@lasersaber:  Thank you for your reply, I understand your hesitation to talk about unfinished work. Making a good video is also a lot of work.

I did not use the transformer from a disposable camera. My choice was the little fly back transformer depicted in the photo below, because I found it in my collection of forgotten and useless things. But winding your own transformer is best because one can control the parameters.

I could make it work with a tower coil (75 mm diameter, 1000 turns, 0.3 mm enameled coper wire) and a 9 turn pancake driver coil (0.8 mm enameled copper wire). But it also had quite a high power consumption near 15 mA at up to 24 Volt in the best case (see at the beginning of page 8 in this thread, also on page 7).

My feeling is, that the Slayer type driving of the base of the transistor is the trick. But I could not do this with the little yellow transformer, only with the tower coil. The interesting thing with a Slayer type circuit is the absence of a trigger coil (because the secondary acts as the trigger).

Strange things are going on at the base of the transistor with the little yellow transformer and I could never solve this issues to my satisfaction. The base going several Volts below the emitter seems to be the worst and I could only solve this with a diode, either like Slayer does, a diode from base to GND, cathode at base; or a diode between trigger coil and base of transistor, also cathode at base, as depicted in my last diagram posted.

I am looking forward to transformer and coil winding according to lasersaber. Somewhere in my house there is a transformer core (similar to what you are showing on the photo), I only have to find it. But I rather believe in big air coils, if only because they look so cool; like Frankenstein technology from the 19th century. Strange claims have to be backed up with strange looking contraptions, otherwise people do not believe them. So, if you want a huge audience for your YouTube videos, put some huge coils in them.

Greetings, Conrad

Heres a flyback ringer being charged by an exciter on 1AA in a phone charger.  Powers a 36W CFL brighter than ive ever seen when just using an exciter.

Ive tried the same setup with 32V @ 1A.  Everything in the room lights up and the ringer rings for a loooong time

Here is a quick update video showing my latest build running in a few different configurations.  Sorry about how dark the video is, before I uploaded it to YouTube it looked much better.

Hi Laser Saber, nice to meet you.

I have some questions of your joule ringer.

I see that you use a bifilar coil, but if you don't use bifilar, the cap it discharge faster?

How much miliamps do you get from the secondary with the CFL and bifilar?

In your other joule ringer videos I see that the part of bifilar circuit, it was open for a few seconds and you were shorting with your fingers. I thought that it was the feedback circuit, but the caps didn't discharge at all(without feedback) can you exaplain me that part ,i'm confuse. U_U

That's not so important but, how can you get HV with the tiny transformer from tiny joule ringer circuit? I mean, the transformer it was smaller than a coin. How many turns from primary and secondary?


well, that's all for now, thank you!
And sorry for some english mistakes(i'm spanish), bye!

hey guys
this is the transistor that is in the high voltage board that lasersaber showed
h1061 is the number
