Joule Ringer!

Hi folks, Hi lid, thanks for sharing the vid, I'll be doing something similar with a box of some sort.
In case people have not seen this video, it is a simple way to power a non-modified cfl and I would think it would be ideal for the led bulbs people are using, though i have none to test.
Though it did fire up my 15 watt cfl to full brightness.
See what you think.

My French inverter ---boxed and ready to use

@All
I finished up my French Flip Flop inverter and boxed it up. It is ready to use now. I wanted that to be done before I tried the inductor on Xee's circuit. I will work on the inductor idea tommorrow. It looks like a great add to the circuit.

Here is the boxed French inverter:

Joule thief with 120 VAC LED bulb - part 4 (adding base inductor reduces current without reducing brightness of bulb)

Hi Xee2,
the power source 1.5 v dc WOW

So there's a chance for a water / or crystal or cement battery
way to go
cheers

Inductor.

I found it helps just to remove the base resistor altogether when the inductor's in the circuit, as it's not needed. All the circuit needs is one oscillation. The LC tank works as well alone as it's RC counter part, in the lower voltage version. So, I suggest that you take the base resistor out if you put the inductor in.

NOTE: current drop is result of decrease in frequency

Base inductor.

I ran a 5 then 15 watt flourescent bulbs simply by tying a 12 volt relay coil into the base tank of Xee2's circuit, like Jonnydavro. A real snap off the breadboard. It works; won't light without it. I used the same 3.3uf 1k cap & pot values. Now an LRC tank. I plan to press the inverter circuit into the other side of the board. I can build that circuit blindfolded. Lot's of fun!

Thanks Xee and totoalas for the confirmation on the benefits of a base inductor addition
@Totoalas.Your current draw looks great considering the load you are runningAre you using the torroid as your base inductor or is it for something else?
Thanks for trying it out and sharing your results.Jonny.

you are correct jonny as base inductor the dimension is 1 1/2 by 1/2 by 1/2 inches this i salvaged from an old UPS there are existing 4 strands in the toroid and i just used the thicker gauge maybe 18 awg i just dont have neons in this ckt but all other values are the same
upsate i can light one fluro lamp 10 w out of 6 in parallel
cheers

Hi folks, Hi lid, thanks for the vid and info. I dug around for a larger transformer and found one bigger and it already had an 18 gauge bifilar as the step down side. This one must be rated for over 100 watts.
So I wired it up and fired up a 15 watt cfl to full brightness, though my mosfets get hot rather quickly, so maybe heat sinks would help.
It draws 1.4 amps or 17 watts with the cfl. We'll see how the heat sinks work.
This bigger transformer has a 5 ohm secondary and each half of primary is .4 ohm.

edit: yes, heat sinks did the trick.

Parts

Hi Lidmotor - I have both the circuits setting side by side and both work really well. I think that I do get a little more out of the French inverter but it is also using a little more power. It could be a matter of tweaking the circuits a little more though as I am not limiting the inverter currant like you are. It looks like a good idea though. I was hoping that you might share what MOSFET's and transistors you are using. I didn't have large enough MOSFET's so I substituted 2N3055 transistors which work fine but I do have to use heat sinks. That could be because I am not limiting the currant. It runs a 7.5 watt feit led bulb with no problems. Lights the whole room. It lights the Lights of America 2 watt bulbs brighter than when plugged into the wall. This is real exciting stuff after working on this stuff for so long. I can't wait to see what's next.

@Zardox
I am using easy to get parts on mine. The transistors are 2N2222 NPN. The mosfets are IRF510. When I first put the circuit together I used IRF730s and they also worked. I think that any NPN similar to the 2N2222 would work. The caps and resistors are exactly what the French gentleman showed on his diagram. I tried other values but could not get as good of results. All of the parts I am using you can get at Radio Shack. This IS exciting stuff. You can put a 1N4007 diode at the mosfet, grab the backspike off the transformer, and charge up a cap to about 3o volts. Put a cap pulse charging setup there and off you go.
Jonny's rendition of Xee2"s circuit looks even better for doing that. These circuits can be used as backspike chargers if one wants to go that way.

The French Flip Flop Inverter on a board and running a radio and LED bulb

@All
I went ahead and soldered up the French inverter onto a circuit board. I am now using a 25 ohm Radio Shack rheostat to control the amp draw. It isn't tough enough so I ordered a better one.
I want to try Jonny's circuit out next and a few other things but getting this French inverter boxed up so I can use it is a proirity right now.

Here is a video of the inverter on a circuit board and running a couple things:

Xee2 Jonny Joule Ringer 201111

Hi.I had a go at Xee's Joulethief/inverter today and I did not have the right transformer but I did have a twin 120v input,twin 12v output one which is quite easy to convert into a joulethief by just connecting the two inner pins on primary and secondary so i tried that and it worked but the output was not too high,probably due to the turn ratio of my transformer so I tried a trick which introvertebrate and myself have tried on Bedini motors which is the addition of a small relay coil to the base circuit and that changed everything.The first thing that happened was the output increased significantly.The additional bonus is that 2 more sources of HV appear across collector emitter and also the relay coil.Both of which could be used for lighting or charging.
The circuit will light cfl bulbs quite nicely and i hope to get hold of some LED bulbs which I think are the best form of lighting for this circuit,judgeing from results posted here.
I also tried running a mains powered radio which is 240v in the UK and it worked quite nicely so I will try and find a 5 pin transformer next and see if output increases.
Here is a circuit diagram and vid.Thanks Xee .Jonny.

@minoly,

You're probably right, I may have just found a new way to wear my battery out. The industrial tolerances of factory transformer windings and battery and bulb manufacturing bring precision to the circuit. The battery voltage depleted untill the voltage hit exactly 12 on the button, then it just sat there! May just have humed up and stewed it's own juice. The power set to the factory bulb setting, the second bulb rings in resonance too. An inductor between the R C tank and the transistor base increases voltage enough to illuminate 4 Watt flouresents. The problem is, magic of resonance should disappear with those voltage mis-matches.

@T-1000,

I'll get to work on that scope shot.

I hope I'm not misunderstanding. My comment was meant to lean in the direction that you have found a way to take from the battery without it knowing you are doing so.

JB and Bearden go over this in FEG. If you hit the natural resonant freq of the electrolyte in combination with your battery, at the right draw, your battery will behave exactly as you have shown and you should be able to take more from it than you normally would under "conventional" circumstances.

so the battery will do more work for a longer period of time. sure it will still deplete, but you'll get more work out of it for "free".

once we slap a resistor in there, the "ringing" should disappear as well as the effect.
