Yes but I wish I coul reach a bunch of this metal used in lamps that has the same thermal expansion factor than glass: I could hace a whisker in and a whisker out the working space...
Brilliant! Lecorfec actually I think you are achieving something quite significant given open combustion and the heat exchanger made from an insulating material! Excellent work and video!
Very nice work... the only suggestion I would add would be to use a slightly larger capacitor to even out the light on the LEDs as it might make your display just a little more impressive. Overall, very impressive, well designed and executed.
There is not any capacitor. the leds are working on AC (1/2 time both way)... I would really enjoy to rectify the voltage but the voltage drop in normal diodes is an issue. I am buying "Schottky" diodes to check if it would be better!
Dear Sir, Very nice model. Rather than Schottkey diodes, try a step up transformer. If you put the output of your "pulsogenerator" to the 6.3VAC winding of an old filament transformer, you would get a 20 X step up to the 120VAC side.. The power loss through the transformer will likely be less than that in any Shottkey diode. At higher voltage, the diode drop will be less significant. . Regards T. Carron
If I hadn't just watched your previous videos, I'd be tempted to call this a hoax. 25 LEDs would be ~500 mW! That's pretty good from what's basically a candle.
That is only one piezo but did you try also with a stack of piezos?

Thanks,
Your proposition seems good but I don't know what amount of heat is transfered to the tube: most of heat is lost!

Looking forward to your next evolution!

Thanks,
it is a bit strange that it works quite well with such insulating material!

superbe demo
cela parait si facile à faire...MAIS NON
vos videos sont une source d'inspiration pour moi.....

Thanks for your contribution!
I will try your idea but not before april I have to waste my time to earn a living until then!
I will then post a video of a radio and an electric motor powered by the pulsogenerator!

You push me to make the next video of the Pulsogenerator powering the 36 leds... but only half of the time for each of them!
I guess a "candle" is quiet powerful from a thermodynamical point of view.
