Jim:

Thanks for posting those links, I have them somewhere but, who knows where, ha ha.  What do you think of my 100 led earth battery experiment?  I am really excited about this!  Now I want big, big supercaps.  Today leds, next month, my home ac unit, ha ha.  (Hey, you never know)

@Bill
Yeay! I knew you could do it!!!!!!!

@Hazens,
Thank you for that diagram

Now there are 2 fluorotubes. This is so exciting...
I have one of those mediums left. I don't have that transistor, but maybe it will be OK. I do have some fuji ckt transistors, but I bet the 3904 can do this.

10 ohms? that is low!
Does it get warm?

400v is higher than the fuji got the volts. I bet you could light a bigger tube with higher wattage rating.

thank you,

jeanna

@ Jeanna:

Thank you very much!

@ hazens:

Jeanna is correct.  My Fuji put out just under 400 volts and I was able to light two 48" tubes (40 watts each) with it using about 1.3 volts input.  They were not full brightness of course but still, it was a lot of light.  I'll bet your JT can do at least one of those right now.

I am so stoked I can't sleep so I made another video.  In this one, I am using the same Earth battery, Fuji Joule Thief, and 2 supercaps to light an 18" long 15 watt tube:

This is fun!!!

@Bill,  Ooh Sleepless one who is so stoked with success, he he.

Congrats with all your success, I took a look at the 1st quick video you put on youtube, very very nice indeed, you wouldn't want to trip over that lot in the dark, you might get ankle jolts ha ha.

Seriously, the Joule Thief forum has really made huge inroads from the plain old simple JT, it's awesome what we are all doing here now.

Con Grads Bill, well done mate.

@all,

I just got sat on my ass     by my Hazens1 JT circuit, hazens, you didn't warn me it has "bite" with in it lol. To make it worse, the battery wasn't connected at all. It whacked me a beauty.

I also forgot I had soldered a 103K 1Kv rated SWC disc ceramic capacitor across the 2 x 100ohm resistors, between the Base and the Toroids leg.

I had just soldered a 104K Polyester capacitor across the output after the single diode, I connected the battery, it loaded up, I had disconnected the battery, then wack, it hit me with 319.volts.
I just measured it on my new DMM.

Hay, is this something we have missed, is the Polyester range of capacitors better than the humble ceramics? Polyester capacitors have a translucent look with them. I have a fer in my parts draws, gonna do some experimenting soon.

But gota watch at Bills second video first. he he.
