Shake & Bake

After charging the capacitor by means of the putting it in the near field of the joule thief coil - then removing from charging, the light did stay on continuously for 5 hours.

Under load (light on) the capacitor still reads 2.5v.
When I turned off the load (the led) the capacitor jumps up to 3.4v. Now this is AFTER the single light was left on for 5 hours.

When I got my flash lights I did a stand alone test and found that each light produced different results as to ability to stay lit, after giving each a fixed number of shakes. But even in the stand alone test I was surprised how long they individually would stay lit.

All 3 still on

Hi David
Thanks for the above. If the cap is fully charged, by what ever means, how long do you think the LED should stay lit for such that it can cast a pool of light? It is now Saturday morning and all 3 are still lit at the same output. The central light which has not been touched has been lit for 63 hours now.

If I get a light meter and measure the light output, what formula could I use to convert that light output into joules, so I could calculate the energy here?

John,

How long? I believe that the duration is directly proportional to the health of the circuit and the cap (leakage) to self charge from the environment.

While monitoring the voltage status it is clear that the capacitor diminishes while under load but once load is removed the voltage bounces back up spontaneously. I would have no doubt that under very low load conditions that the circuit is self powered. But it must be achieved with just the right balance of component factors and frequencies.

The simple capacitor can often do things that batteries cannot - I think this is one very good example.

I wonder if the fact that the circuit is totally enclosed in an insulator has any effect upon the performance?

Ok, update, Sunday evening after 110 hours the LEDs are not so bright, though the middle light still casting a discernible light pool. Waving a aluminum pie over the torches made the lights flicker and 2 went out. Shook up one torch, when replacing it, the other outer torch started to flicker. There appears to be some form of coupling going on here, rotating the torch appears to find a sweet spot between flickering and on continuously, I will take one of the torches apart and try and find out what components are used.

Fake and existing thread.

There is another thread about exactly the same.

I stated and explained there why and how this is a fake, though there has
been cheaper and bigger scams on the market lately. Anyway you can see
it here:

Aromaz is Correct!

So following on from DavidEs suggestions, I have now taken one of the torches apart to check the components.......guess what?

The wires from the coil are not even connected.
The large caps are in fact 2 x CR2032
The magnet is not a magnet

The internal construction is so poor that just rotating the torch moves the batterys making and breaking them. No wonder the performance was so good!

So I have been scammed by e-bay. If nothing else, looking at the funny side, this has kept me and a few friends well excited since last Wednesday thinking there is a fantastic resonance effect here. So back to the other half being again not impressed but smug!

See attached pics of the internals - will I get a refund though?

Well the workmanship on my Chinese version is superb

That being said - I still am amazed at the charging effect when putting the coil near a resonant joule thief coil. The resultant light intensity and duration is far greater than charging it via shaking. As long as the resonant circuit runs, the light stays on and is very bright.

The capacitor can be charged and conditioned by means of electromagnetic induction. Depending on the efficiency of this, it is a very interesting mechanism that warrants additional study.

Thanks for that, when I get some new torches I will give it ago. Must say very impressed with the firm I got the 'fakes' of. I wrote t them this morning explaining that they were fake and the reason why - this evening had a letter of apology, full refund and can keep the torches! Any suggestions what to do with the bits?
