Joule Thief

[jeanna]

I am re-reading this thread a little at a time, and I see on page 17 Dec 12 first groundloop made 2 drawings that are very close to what this is and then in the next post #166,  wilby added a picture of 2 thiefs running off a common battery.

So, what I am doing here, is using the cap by the battery to keep it steady and at low amps and long duration.

I am not sure about the amps, yet. It may be the number of turns more than the battery cap.

I am thinking about the turns ratio from primary to secondary. It is true, as xee2 predicts, that the lights in parallel on the breadboard are dim and cannot be brought up as they could in the circuits I have made using a toroid with few secondary turns.

I guess tomorrow, I better make that variation to this breadboard one. I will let these 2 run all night. The soldered circuit here is very bright. It has a VR on it too but the range is only between 500 and 1K, so it won't dim very much.

I am making gloves for a friend, so my hands are pretty busy for now.

Well, when I got back from work, I attempted (twice) to make another video but my experiment did not work out like it was supposed to.  I hate when that happens.  I will try again.



@ IST:

That is a great idea for the garden lights that resemble flowers with the pedals being solar cells.  Very good thinking all around I would say.  Cheap to make, very functional and a little twist that most folks would love.  This is the kind of creativity I enjoy and respect, and I have seen a lot of it right here in our topic.  You should make those.  It may not make you rich, but it might pay for a lot of wire and supplies.  Excellent idea!

I agree with Ist idea . I see Little tiny flowers and little tree garden lights . you plant them in the ground with copper zinc trunk at the tips of them there are leds and as a boost solar fruit with of course the major part  our little modded JT Great . Lest hurry up make a prototype and start selling .. We can make Millions . just look at those water globes . he already sold MILLIONS OF THEM > this will be a great addition to anyones home /landscape // no ugly solar lights only pretty little bushes and flowers that run from the earth ....

@ Gadgetmall:

Agreed.  And to those who say...."well, you guys are only in it for the money," I say, hey we need a little money to carry on our research here.  Not a lot, but some.  I have supercaps, large ferrite toroids, big blocks of magnesium, solar cells, etc. on my wish list at the moment.  These are not free.  So, IST, go for it, that is an excellent idea that I know will work.

@ Jeanna:

I caught your idea about the little galvanized buckets.....and then carbon rods and JT circuit?  This one is also an EXCELLENT idea as well.  Cheap (inexpensive rather) self powering led lights..........you probably could not make enough of them to keep up with demand.  I admire your thinking and creativity.

I know others here also have some ideas that are great as well.  I really enjoy being with you folks and I can not wait to see what we do next.  God bless all of you.
