Joule Ringer!

[flathunter]

Sorry guys!

I made a little mistake in the circuit of my flyback oscillator (use of the word ''my'' is dubious....the schematic is an improvised version of slayers exciter and conrad and xees and koolers flyback designs.)

The correct version can be found on energeticforum.com - im afraid to post any more pics on here as it seems to screw up the screen.  Sorry again!  (IN WORDS - the secondary on the flyback connects directly to the plus on the cap - it doesnt go between the resistor and small cap)

Please try using an av plug near an exciter field to charge the caps on your joule ringers - i think you'll be pleasantly surprised by the excellent results.  Have patience and use an LED/av to sniff out when the flyback (or trigger transformer) reaches resonance - if it suddenly loses resonance, just put your arm near the exciter tower.

@lasersaber:

Without a circuit diagram and details about transformer and coils, it remains some sort of a teaser.

I believe it is working as you say, but I could not replicate the alleged performance (see my many posts in this thread).

+ @all:

My tests (with a little fly back transformer) showed not difference between a "resistor-capacitor pair" and a "coil terminated with four 1N60 diodes" connecting the trigger coil to +V. Obviously I am doing something wrong. My best performance was a power consumption of around 5 mA with 12 Volt and around 300 Hz. The brightness of the 15 Watt CFL was low (like one of the small CFLs on your latest photo). For a decent brightness (reading at 30 cm distance) I needed 35 mA with 12 Volt.

May be the secondary has to sit on the base of the transistor (or on the other end of the trigger coil) like in a Slayer Exciter?

I got ten surplus fly back transformers (for PC-Monitors), all different. Removing the core (of two transformers) was no problem (I leave the others as they are for the moment). Without core (as kooler did) I hope to be able to run the circuit at a higher frequency (which should result in higher brightness of the CFL).

A question at experts: One of my fly back transformers has the HV-cable (the one with the suction cap) missing. Examination of the "hole" where the cable should be, showed no metal part in it. Is it possible that the HV-cable is not actually connected to the secondary coil but receives the high voltage by induction? (Just being very near the coil along its whole height?) I do not want to rip out the HV-cable from one of my other fly back transformers (to have a look) for fear of not being able to reconnect it properly.

I will post a video showing step by step how to build this device in the near future.  The delay on that has been because I do not want to have to remake the video again and again as the device improves.  I am now at a reasonable level of performance, I have found exact parts and where they can be ordered from and I know how to wind the transformer from scratch.  When I get the video done it will be all that's needed to replicate the device as seen in my last photo.

I believe it is working as you say, but I could not replicate the alleged performance (see my many posts in this thread).

Which camera transformers did you use?  The only ones I have gotten to work were the Fuji AA version.  The transistor that comes with that camera works best as well.  Did you ever replicate the circuit as shown in my video titled "Joule Ringer update + schematic."  The only difference between that version and my newest one is that I made the new transformer myself, used a different transistor and added the second coil to smooth it out a little.  I works almost the same without the second coil and is just as bright.

I am amazed you and others have gotten this to work so well using a fly back transformer.  I will have to try again but I could never get it to work very well with one.  Thanks sharing all your work on this project.
