Joule Thief

[jeanna]

Hi everybody,

I have been trying out different light fixtures for the latest high voltage "xmass" toroid.
It is so perfect as a light and even more perfect for use with the rheostat, but this funny thing is happening.

Since I can screw the unmodified bulb into the base of the fixture all I need to do is attach the secondary wires to the switch of the fixture.

WRONG.

There appears to be significant HV leakage.
Those lights are glowing very dimly right through the turned off switch.
They glow a bit brighter if I touch the bulb.
I am sure this is because of the nature of HiVoltage-Hi frequency (727v, 6.5KHz), but I will need to attach the battery to the switch as usual and solder the secondary to the screw base to get around this...IF it will even get around it.

This is a commercial UL tested light fixture new from the store. So, there is not a question about it being old and wire weary.

Anyway, I thought this was interesting enough to mention it.

@Gadget and Jadaro, I will be very interested to see if you can get warmth from these even with an insulated case. There seems to me to be no heat production at all over here.

I was wondering if the toroids get electromagnetically coupled? ..are they placed perpendicular to one another, or are the linear?

With toroids all (or most) of the magnetic field stays inside the toroid so there is no couplilng to things around it.

@ All

I am very happy to have lit a LED on 1x Earth cell .8 volts at ~4 mA's of (19 3/4 inch long copper and galv-steel) running direct into a very basic Joule thief with no cap at all and a Bif wound coil + a secondary coil on small toroid.

LED lights up good on secondary coil or just connected normally.

I would like to run my complete house lighting off these, but I would need 100-200 of these cells in my back yard -depending on how bright I get these LED's to light.

1x Earth cell .8 volts at ~4 mA's lights my LED - good  ... FREE POWER
2x Earth cells .8 volts at ~7 mA'a connected together lights LED - very good  ...FREE POWER
1x AA battery lights LED - very bright

One photo of LED lit...

Hopefully I'm on my way to absolutely free power...


Sorry for cap in photo... that was taken when I used cap, but since I have now taken cap out and I dont need it now...

Can anyone help me with taking this (1x Earth cell-Joule thief-lit LED) experiment further

Freepow:

Nice job lighting the led.  Check this topic out here:

Lasersabre just hit 1.6 volts and 38 mA's on his set-up.  He has been running a small electric motor on his cell for many, many hours now.  The last time I checked on my EER it was at 1.9 volts and 19 mA's still.

Jeanna, Gadget and all:

Check out this video of how to make LED ice cubes:

It does a nice job as a diffuser and uses some clear resin similar to what Gadget was talking about. This stuff would allow us to make all sorts of diffuser designs, not just the cubes.

Anyway, thought you might like to see this.
