Joule Ringer!

@ kcarring

Try this.

EDIT: If I understand what you are doing, when the capacitor is discharged the mosfet is shorting the power supply to ground and this energy is not doing anything (just wasted). With this circuit the energy goes through transformer and builds up magnetic field. I think this will give more brightness for the same current. However, I do think your circuit will give AC whereas this one does not (but it sort of does).

@xee2vids

Thanks. I'm assuming you have over simplified the 555 setup, and meant the diagram to be a mod to what I already have set up as an oscillator?

You are correct. See edit.

@xee2vids

Thanks. I tend to believe you on the short to ground, because when things DO go wrong, with my circuit, for example you decide to change capacitance and overdo it, or try a new FET... and if things go wrong, the ammeter hammers into the multiple amps, FET fries, 555 cooks. It's all or nothing LOL I have a little IC/FET burial ground from this experiment. Thanks I'll try what you have there, interestingly simple, like most of your stuff, it's been a lot of fun.

If you are burning out that many fets you may need to increase the 100 ohm resistor value so that fet does not turn on as much. Try 1K.

SkyWatcher's split positive.

I spent a few days sketching up circuit schematics to switch the 3 batteries around automaticly in SkyWatcher's split positive Joule Thief system, when I hit on a pretty simple solution: 36 wires; Six SPST on off electronic switches, and a timer chip. Six wires from each of the battery poles to a long breadboard. Each set of wires arranged and connected in the next battery permutation order. The timer simply turns the switch on to each set of the 6 differently ordered wires sequentialy at 8 hour intervals, and Viola! A tiny photo voltaic cell should recieve enough power from the Super Joule Thief bulbs to recharge the 9 volt switch battery.

@Xee2vids

I tried your mod, but couldn't get it to fire up.

My next trial circuit will be this one:


I'll probably drive it with mosfets instead, though.

Another really interesting setup, more high tech, and low voltage is outlined here:

My next trial circuit will be this one:

Good luck. Please tell us how you add the extra coil needed.

Hi Kyle,

Why don't you spend 5 minutes watching this one -

Joule Thief- Joule Ringer

Take special note of the two identical bulbs. One is in series from the supply.

Penno

p.s. circuit is posted at OU in joule thief thread, I think.

is this one

for now work only with this bulb ,with 5watt bulb no success

@penno64 Interesting video.. I understand the diagram... and I think I understand what is happening... what is the amp draw? Thanks

@xee2vids, ok will do. I figure I will take a toroid, wind 100 turns, figure out the Al, then rewind for correct uH, if I can't find one that fits the bill. Been vusy building this.

Cheers

Since this is one from the active JT Threads, i will post a link here from a guy what added an 10n Capacitor to the Base from his JT Design.
His efficiency did go up with Leds, not sure if it is the same with light Bulbs, but maybe it helps.

the video is mine the amp draw is 430 mA
work also without diode with bulb connected to : C 1,1 2,2 3,3 4,4 5,5 6, with the same amp draw
in practice the coil is six wire in series and i take the energy only from one wire i have try 5 watt bulb with no succes

can you tell me what you think is happenenig becouse i don't understand
thanks

Fuji/Kodak mod joule ringer circuit...

Hello...

I just finished assembling the basic circuit with Gadgetmall's 68pf cap/20k pot modification and a 47nf cap from the base electronic ballast from a CFL to put in series with the bulb for additional brightness.

The circuit works good, with a std 1.5v, 595mah battery it ran, full output, for 3hrs 45min. Running it at 3v I got the same results. I only changed the pot to a 50k, maybe should use a 100k so it can be used as a dimmer but really don't need it.

I'm now going to move on to adding Lasersaber's bifiler coil to the circuit. Is this bifiler coil to improve the efficiency of the circuit and give it longer run time? In any case this is my next step.

Here is my completed light project...
