Joule Ringer!

[xee2]

This works slightly better than the toroid inductor. Going higher than 22 milli-Heneries did not seem to be helpful. I do not know who manufactured it (bought at surplus store). Resistance is 27 ohms.

Different Inductors

Here is a short video of the Joule ringer circuit
with the center tap transformer and an inductor
in line with the base transistor.
The first small toroid inductor is at .1 ohms.
The large inductor with 10,000 feet of wire is at 134.4 ohms.
And the solonoid inductor is at 268.1 ohms.
I was supprized to see the little solonoid was a higher resistance
than that of the large inductor. Maybe it's the iron core inside.

I've been trying to get Xee2's circuit running with a 1a 120-12.6 VCT, and both MJL21194 and TIP3055's... but so far, all I get is a sharp blast off the bulb, and jump to about 1a draw.. then nothing. Doesn't latch and start oscillating. So I tried changing out the base resistor to 2k, 1M, 300 ohms... tried removing the cap. I have a 3 watt Rheostat inline with the input side, too... when I run it with no rheostat, it peaks HUGE... right up to 5A (So I don't do that a bunch!) .. the flash is way brighter than it ever gets, ran normally. So not too much luck yet. Also tried switching the primary wires around (leaving the center tap of course).

hmm

maybe my components just aren't close enough.
you'd think it'd run tho.. it i could just get it to oscillate.
maybe i better hook up a pot to the base.

** update, got it running. Thanks Xee2! On a side note: My Mastercraft $50 300 watt inverter made the bulb buzz and flicker... whereas this circuit is clean running! Works great!


WOW...
I was horribly unimpressed (to be honest) with its output/input at 12.2 v... then ...
I threw it on a 3.7v lithium ion cell, dialed it in on the base a bit , and BANG, started to hum a bit... input dropped to about 180-210 mA
great light...

I think I know why they call it the joule "ringer" now.Ultra efficient or not, I love how it is AC... that has real benefits! My Li-Ion was running (still at 4.05v) after 20 minutes of playing with it. Running at about 240 mA, the room (otherwise pitch dark) was adequately lit (that's less than a watt!). One more as a desk lamp, and I'd be reading a book. Throw 2 tiny solar panels producing 6V/200mA (so 400 theoretical) at each battery in the day... and you got some free light all evening! Just what I'm after.

XEE2 Joule Thief / Ringer Replication Video

Many thanks to XEE2 and all you folks, this is a very useful alternative energy circuit indeed. Here is a vid of me playing with it, in the dark, and a comparison to the light produced from it, and an incandescent night light.

@ kcarring

Thanks for sharing your results.

I played around with this setup today. The output could light LEDs up to 500V. This already made radio shack transformer is a blast. I was trying to make an inverter that deliver high current, but it seems these design only carry good voltage. However I've find a trick that can convert those high voltage to current efficiently. Yes, cap dump. .82uF 2100VAC charged to 500V and dump to light up a normal bulb. Continuous short won't light it up. It's rather an interesting thing that you can create heat or not on the same output.

Hi guys!

I have something similar to a joule ringer here - I can keep a CFL lit for a few mins after a quick blast with 1AA in an emergency charger. Heres a video with the circuit diagram. I'm using a flyback for my coils and a darlington pair arrangement. (TIP 31C).

Without the cap/neon parallel addition, it'll light 72W CFLs (but with no ringing effect). Admittedly I get the same results with MJE13007 as well as the darlington pair (and the IRF series)

Hope its interesting for you guys!

I just have a fresh idea this morning how to dump cap through air gap without resonance. Going to try building voltage multiplier and connect it to the joule thief AC inverter until it jumps gap. If OU lies in capacitor disruptive discharge, then this method could replace resonance.

Very nice

does your AA have a boost there in hat little pack?
interesting how you have the coil hooked up...
will have to give it a try. thanks for sharing the schematic.

Yeah - its a typical little 1aa emergency mobile phone charger - they are very cheap. Boosts the 1.5V to 5V.

Getting it tuned takes some time - I had to try a lot of different resistor/cap combiantions to get it acting like that with the CFL. But Im sure i can get it working better, as I was able to several months ago using an exciter and AV plug to charge the big cap.

@Seth
it was your video that got me back into all this, after a couple of misfires with wrong transformers.

I'm delighted to say that i'm in the club ! (wait, that sounds wrong)

First runner, of the 3-2 transformer type, but not using a RadioShack one.
15W CFL
3.7V li-ion salvaged battery
150mA, drops over time to I don't know what yet, by 10mA in 10 secs

474K capacitor
120K pot just to dial in on the Base, sits midway and fires
RN2Z diode ( http://www.yu-ke.com/uFile/1513/2009102616926885.pdf )
Transformer - WH35-14B40

All salvaged from general cr@p and slung together generally cr@p, but works

Variation:

This one is same setup, same current draw.
Found that the battery is actually flat, so that's why the current went down on the other setup

Thanks Slider!

Have you got a circuit diagram for your PSEC build? I wondered how you had it hooked up. And have you got the one above ringing? I mean does the CFL keep flickering after the intial charge?

Here's a better video with a radio to pick up the frequency as it slows down.

[Slider2732]

Haven't got anything ringing yet...not even had a phone call today
Just starting out and have something to start from. It was that simple push to go at it properly that was the needed thing, to catch up a bit
Will PM ya more info on the PSEC type experiments.

Hi.Here is another modification to the Xee joulethief transformer which seems to work quite well.I added the lasersaber base diode and put a capasitor in parallel with the diode and in testing with a xenon bulb i found that the xenon would fire at lower input current levels and it also delays the bulb going out.
Here is a vid.Jonny.
