Joule Thief

@ jesus,
ElecCalcuCap.ZIP file

Thank you for finding that capacitor calculator, I right clicked it and saved the file to my C drive, I clicked on the exe and it poped up.
I dragged the exe to the desktop, it has a nice smiley face icon to click on.

As most of us guys here need it translated into english, so I emailed the software owner asking him if he might do this and put a activation click icon to click on to run the calculaton.
Other than that, good work.

@ ist
Nice work getting all those capacitors, I bet if you hook them all up together they will make a few Farad
What you planning to do with all them caps ist? I know you by now, you got something secret planned up your sleeve ha ha.

@MK1,
Thanks for the thanks, nice to get them once in a while.
Those transisters on your perf board, what value might they be? hmmm got to be a NPN and a PNP, depends on your circuit there.

I will take a look at those Utube addresses shortly, buut first I have to post my work I did today, ist is wanting to know, I know, I know, I just know, ha ha.

I think your one inch toroids are the same as some I used a few years ago. I was able to get over 50 volts out using only 20 turns in the following circuit with one AA battery. If you use 200 turns you should be able to get over 100 volts out which should be enough to light one of your 100 LED Christmas strings. May only required 50 turns, but since I have not tested it I put 200 to be safe.

I added that cap between the positive coming from the battery and the negative going to the battery a shown in the picture to see what it would do. For my big toroid, it did absolutely nothing. The same steady 3.2vdc and 98mA dc.

@MK1
The bridge rectifier is soldered together and tomorrow after work I will see about some more winding on my JT. Actually, I really need to just re-wind the whole toroid because the wires were too short this time and everything is crowded. I just don't like that. I didn't solder everything together very orderly so it's time to start over. I've got a little bit of magnet wire that I think will work for my big toroid. I will try it tomorrow afternoon.

Ok, I have to be up in 5 hours. L8R.

@electricme

Yes they are pnp and npn , i took them a printer board they are made to drive dc motors .They are a2023 and c5611.

@all

It is possible that you already have a ready made bridge diode in old power supply there the ones with 4 legs and a + and - on it.usually black like a big transistor.

@all


I made this for you , so this is my single jt with pickup coil , it is in the blue box and each ends is to be connected to the diode bridge(after that you can experiment charging big caps or lighting many led lights.

In the red box is the regular led circuit but it has 2 led and it is the part that we should try to reuse to make initial pulse, but since it is high in voltage it is hard to feed back without effecting the current at the resistor that needs to be stable because it will change the freq .

So that is when i decided to but 2 of those on on toroid, to bounce energy from one side to the other.

***REAL IMPORTANT ***   The number of turns on the coil work on a ratio factor at the same size. 1volt 4 turns IN = 5volt 20 turns Out .

But since there are 2 wire on the joule thief by making it the same amount you just double the voltage , So the initial potential is not 1.5v but the double 3v.

Sorry i try my best to be clear and simple in my explanation but i am a pour Frenchman,lol

But some german?  Electricme you got zapped?

@MK1
Thank you very much for the diagram! 
My question is if you connect the ends of the pickup coil to the bridge, which ends of the bridge do you connect them to and what do the other ends of the bridge connect to? It does not look like they connect to anything in the diagram.

@timmy

You connect the pickup coil to the ac side of the bridge. That is also covered in detail 2 or 3 pages back.

@all

Good work.
I still have some tricks up my sleeves .
