Joule Thief

[stprue]

someone posted this one which is real nice..

Yes this is the one I was looking for Kooler.

Thank you much!!!

@conrad: thanks, the reason for the Schottky makes good sense, and I think I agree with all the rest of your post as well. I even got my JT test bed with basic JT circuit to work using the 40+40 turn bifilar air-core coil I wound just for the demonstration (connected as bifilar with the head-tail interconnect connected to the positive rail) , but it does use more current. I'm getting some very interesting effects with the modified Loopstick variable inductor w/ primary, but I haven't gotten around to videoing it yet.

Here's a circuit I found that seems very interesting and might be adapted to run an LED from the "electrosmog", but might need earth grounding.

@TinselKoala: thank you for the circuit which uses the mains humm as a power source. The full bridge rectifier seems to be the way to go. It could work in combination with the low Voltage Peltier Joule Thief circuit at http://www.overunity.com/13175/25mv-joule-thief-powered-by-peltier-merely-using-our-body-heat-free-energy-247/ . I ordered some 2SK170 transistors and will try.

In order to catch high frequency electro smog from mobile phone towers and WIFI spots one needs very high frequency diodes (8 GHz). I have some, but not being at home at the moment I can not look them up just now. Will post their specification some other day.

By the way, all AM radio transmitters have been shut down in Europe. Only some Eastern European countries like Russia still send some radio programs via AM. So, one has to go for FM (60 to 120 MHz), TV (400 to 800 MHz), cell phone transmissions (some GHz) and the WIFI and WLAN spots (up to 8GHz) or the 50 Hz humm from the 220V mains (which propably is the most promising).

Radar could be a power source (because all countries sweep their territory with Radar, and they reach up to a 1000 km radius overlapping each other. But the frequency is around 400 GHz or even higher. There are diodes for this frequency but they are not easily available on the market.

An other area is VLF or ELF (down to a frequency below 1 Hz). The military uses it for submarines and also lightning causes ELF transmissions. It needs very long antennas, but my garden fence could be the antenna. There still might be some surprises in the ELF range (http://en.wikipedia.org/wiki/Extremely_low_frequency) , it is not well researched. Nature might transmit something there which could be used as a powersource.

Greetings, Conrad

@Pirate
Thank you Bill....... I will B in touch shortly by land line
@TinselKola, I like your Crt drawing in the "air power" to run a something,,,,,, put a Super Cap on it's output and see if you can save it.
@Conradelectro, exactly, spot on about the caps.
Q... how do I cram 1,000,000 posts since I was here last? lol
@ Everyone, Happy new year to you all.

Another circuit.

@Tk like the circuit, I remember building something similar many years ago.

Happy 2013 everyone!
