Joule Thief

@all

Well it seems a have made enemies,All i see from that is a reflection of the world ,always tools to discredit people and limit knowledge,
most people still what to get rich quick, some are here for that, some are here to learn and so to share knowledge.Is that really what is needed.
If people help each other instead of making money of there back, we would not be in this mess to begin with.Most of what is done here is not much different then 100 years ago except tesla was a genius but was a man, Today modern man has the brain pickup where he left off,if we use it, most of the time we just complicate stuff since its supposed to be,but really is not.

I am sorry to revise my last experiment reading on the meg thief , it still gives me 66 volts dc when rectified , but only 25ac ? I got this wrong or is this strange, i will try some type of grounding earth or the neg of battery.So i got two coil giving me 66 volt dc.

If anyone has a tough on this , input would be welcomed.

It is certainly possible. But, without providing more information about what you are doing it is hard to tell if there are any errors. The following is some info on AC that I put together. I hope this helps.


EDIT: These statements are generally true. But when the AC is not a pure sine wave the only way to really make good measurements is to use a scope.

@ All:

Nothing really amazing here.  I had a few minutes so I charged up one of my new supercaps using a regular battery (1.5 vdc) for just a few seconds.  Then I took some jumpers and hooked to the - on the empty bat. holder and the + on my switch.  Flipped the switch and.....it lights...very brightly too.  I had some other things to do so I just let it run for the fun of it.  It has been 16 minutes and it is still on. (Maybe 60% brightness?)  The led is a 10mm superbright, white, 28,500 MCD.

Bill           ***EDIT***  19 minutes and the led is all but out.  Remember this was only running on the capacitor, no other power source.

Reel nice those are incredible parts, there not called super for nothing.

This is great.

Some idea on what to do next ,we will need so see how it works when it is feed by a pickup coil , maybe making a special one just for it with as many turns then the jt coil to get the initial impulse back, the real big problem i see so far is to feed it 1.5 volt because i have made experiment with higher voltage on the regular joule thief and at 3 volt you get a 40% lost in energy(it could be limited at input but the jt output about 6 volt at the led and would need to be down at 1.5 in the cap) . But if you only take as much as given it may be enough to get resonance, self resonance.If we can get it to resonate we could tap that energy real easy .

Remark on the TPU unit, it needs 3 freq , its like 3 note make a cord on a piano or guitar we should think of that when tuning it.
