Joule Ringer!

[flathunter]

Hi Guys!


I've managed to get some great results with a very simple circuit which may interest you.   600 - 800 microamps lighting lots of CFLs and xenons on 1AA.  The circuit is just a darlinton pair (TIP 31C) a 280 ohm resistor, and a flyback.

And here is another video of a very similar circuit demonstrating the ''ringing'' effect that Laser showed us all those months ago (Thanks Laser!  Im a big fan )....it also shows the current draw with the CFL lit all the way down the (literally) the last microamp....Im using 1AA in an emergency charger to give the 58000 microfarad cap the initial blast of energy

@ Laser et al,


Interesting video from Laser on Youtube (the toroid combo lighting an array of (120v?) bulbs. Fairly serious and non-delirious. I shall upgrade my vanilla flavoured joule thief.

But I wonder (as commentators on YT have also asked), whether this is an abstraction event, which is to say, that by resonant induction, the ferrite toroid (with multiple windings) is really grabbing electricity parasitically by induction from the surrounding electrical crunchiness (e.g. from the mains voltage supply in nearby walls etc).

Is this parasitic abstraction (we could use other words) of electricity by resonant induction (getting free electricity from wires in the wall)?  Or does Laser's ringer work more than say 20m away from any electrical mains wires and sockets as well?

Finally, and only slightly off topic, another wonderful youtube publisher (aside from laser) is Afrotechmods....and, getting closer to being on topic, he has some fascinating inductor and transistor videos; the best I have seen on Youtube. His video entitled 'Fun with Ultracapacitors' is funny. I sprayed the tea I was drinking over my power-supply. Certainly the most amusing electrical engineering video. Coin collectors may find the video hard to watch.

Great schematics from LaserSaber!!!! Thank you very much!!!!!

Suzanna is published a new schematics of zero point reciever

I drew a similar diagram with an input of 2 long wires to two counterwound coils.   The output was immediately rectified and taken to a battery.   The drawing is still somewhere, but mot necessarily on my old Sandisk thumb drive that doesn't work with newer software.   I might have to look for it later amongst my notes.

I have read the entire thread on the joule ringer and watched the related videos, find it quite interesting to produce such ample light with such a small current draw. I like the idea of building a small V.A.W.T. to produce enough electricity from the wind to light an area. I was wondering about the torroid itself being difficult to find, and I did some experiments using other materials. Soft iron has the tendency to become magnetized so it would not work for this kind of circuit, but if a soft iron core is pulsed with DC pulses where the polarity of the input is reversed every other pulse, I think it is possible to use a core made of something as simple as bale wire. I am not experienced or very knowlegable of electrical circuits, so if there is someone out there who can recognize some problem with this idea I certainly would appreciate being enlightened.

Nice of you all not to address my newbie ignorance of using a soft iron core, after some testing it seems that quite a bit of amperage is needed to induce a magnetic flux into an iron core so the efficiency goes right out the door. I did find that alot of speakers use perhaps Mumetal backings on the magnets. I believe that cutting the center out of these large round speaker magnet backings will yeild a large flat washer looking ring that could perhaps be used as a torroidial core. Should I get my hands on one I'll be sure to post the results of my findings. Happy experimenting!
