Joule Thief

Where did you get the good deal on those leds again?

Ebay. Follow the link. Takes about 2 weeks from Hong Kong retailer. He has all kinds and many different colors. I bought the 100 super bright white for $8.99 shipped.

Edit:
I plugged my 7-7-70-70 coil on the Goldmine 1inch 5for$1 toroid into the circuit. I changed the cap to a 100nf. I'm measuring 42ma input and of course this coils sings as I believe it is resonating. LEDs are approx 3 times brighter than my previous test with the 3/8 inch toroid at 100ma input. The first pic is with the lights in my room dimmed and the other 2 are with the lights on. All pics are with the camera flash off. I'm gonna wire in some more LEDs in series. I bet this setup will light all 100+ of my LEDs without flinching. Talk about Super Bright

@ hazens1

Congratulations on your excellent circuit performance and thanks for posting the photos and circuit diagram. I also think your 7-7-70-70 will light 100 LEDs. It may even be able to light a CFL if you remove the rectifier.

Wow Hazens1, this is great. It is so bright!
Have you tried these non rectified?
I think they should work without the rectifier. I am curious.

@All,
I think I am making my second tier thing too complicated.
I am beginning to think I only need an ordinary inductor.

I have never made one, but it should be easy after all this circular type.

Last week or when it all started, I had made up the 2 tiers and used the secondary from one to power the next.
But it was terrible. It was very dim.
MK1 had just mentioned that some of these transistors are able to work in reverse direction. So, just in case mine would work backwards, I took it out to flip it.
But when I took it out nothing happened to the lights. So, I had several extra wires, then I dropped one and it landed on the a hole and the lights got very bright, and that is when it all started.

I can see by the diagram I put up earlier, that there appears to be some duplication of leads. Maybe I don't need so many wires. Maybe I just need 2 and maybe neither one needs to be bifilar. At this second tier place anyhow.

It should be easy to try.
I will get to that this weekend.

thank you,

jeanna

@ Jeanna:

I have been working on replicating Jonnydavro's No Bearing One Magnet Bedini Motor.  I have 2 videos on youtube but have not posted them here as it is a bit off topic.  However,  several other folks have placed air core coils along the high speed spinning magnet and are getting very good power output from them.  these coils are no more than a Radio shack coils of magnet wire as it comes from the store.  This is being used as a "pick-up" coil.  Not bifilar.  Maybe the same thing is true for your pick-up coils as well.  Let me know and I can post links to mine, Lidmoter's and Jonnydavro's videos on this device.  Great work Jeanna as always.

@all,
You are all doing excellent work here, puts me to shame with my lack of posting, but I just did something which took over a week to do.

This is not related to the actual Joule Thief itself but it could be.


My Accedential Experimental Battery Recovery Experiment.

I got myself 2 x 12v 12AH Gell cells from my local scrap place, it turned out 1 was OK, but the other Gell cell batt just wouldn't take a charge, no matter how much I abused it. Read trying to pump in a 12v batt a charge of up to 28volts.

So I took off (prized) all the access covers, and put in 20mm of water in each cell.
Still no go, it wouldnt charge.
Then I added about 60mm of hot water to each cell from the tap, now it began to recharge, but only to about 5volts.

Then I boiled the billy, got the water stinking hot, filled the syerange and put some more "HOT HOT water" in each cell.
Well well well, the battery recovered, it came right up to full voltage, at a charge rate of 13.1 volts at half an amp.

I can only assume, the hot water was the key to break down the sulfation on the plates.
BOILING WATER, be careful with it.
