Joule Ringer!

@lanenal

That looks great!  I am on the road with work right now but I will give it a try when I get back in town.

@All

I am almost ready to post the DIY videos on how to build a joule ringer including the transformer.

I have also discovered that the Joule Ringer will run a lit CFL for a couple seconds after the power is disconnected, even with no electrolytic capacitor in the circuit. It just runs on the coils alone for a few seconds. I will also show this effect in my next videos.  Here is the circuit that I use when running with no capacitor.

Hi lasersaber
that is great news. I have been so busy with the air batteries I haven't had time to explore your joule ringer that much, so I am looking forward to your DIY video!!!
Thanks

Great news lasersaber !

Maybe your bifilar coil then acts as a cap,
as in your bigger designs it probably has about 100 nF capacitance between
the 2 wires...

Looking forward to see the videos.

Regards, Stefan.

@lasersaber: I am so thrilled that you will give the modified circuit a try! Please let me know your result. Look forward to your new video, expecting myself to be shocked again.

@all: Here is a kickback joule ringer circuit. This time I have added a diode across the C and E pins of the transistor, and a 70pF capacitor in parallel with the driving coil. The main purpose of these two new elements is to help kickback the energy stored in the driving coil in the collapsing phase. When the transistor is turned off, the driving coil will oscillate with the 40pF capacitor, but only for half a cycle, thus when the current in the driving coil is reversed, the diode across CE start to conduct and the energy in the driving coil is kicked back to the 10,000uF capacitor.

Based on the understanding I have, I would like to propose a modified Joule Ringer circuit as in the attached. A diode is used to encourage recharging and forbid discharging. The value 1N4007 is tentative (ideally, it should have high breaking voltage and fast response). The 4M pot is for standard Joule Thief trigger coil configuration, which will regulate the frequency.

Clearly, the huge spike picked up by the power coil is directly dumped onto the cap. This is something to be careful about.

This reminds me of the Micro TPU!
