Joule Thief

Hi jim,
I picked this one up from Jaycar ( the Oscope ) for around $178 if I remember correctly, but was on special for $150 the week prior, bummer missed out on that. I got hold of my dads very old dicky smith cro and turned it on once to check out my NS coil that I had in the ground and about half an hour later the thing died, so had to get another, I heard the usb's oscilloscopes were ok, I wouldnt know as I am still working it out.

Have any of you guys had any success with lighting up a string of Leds or cfl's with the Fuji AAA board, I posted earlier that I had the AA but after checking it out again it is definately a AAA, maybe this is why I am only able to get around 280vdc, I also noticed that the board is slightly different to the AA, but I think you guys already knew that. If this AAA board cant light up anything, and I cannot find a Fuji AA board then I think I may have to make a larger coil and hook it up as a secondary, any suggestions on using a Fuji AAA to light up a string of led's or cfl's would be very much appreciated...oh btw I also have some Kodak boards..all AA's are these capable?

Thanks

Wayne.

I have lit 400 leds (4 strings of 100 each) using the modified Fuji AA.  I have run my Christmas lights the past 3 years using this little circuit.  The amp draw is fairly high, but not that bad.  As i mentioned, I never had any luck with the AAA board, although I know that others have. I have to say that I get more light by lighting two 40 watt 48" tubes with the Fuji.  I have done cfl's but I don't like the light output from them for the buck.

You can see this on my youtube videos.  I have also lit 400 leds from the Fuji powered by my earth battery only and no AA.

Jim:

Great to hear from you Mate.  As I just posted to Wayne, try lighting tubes and not cfl's.  I have done both and you get way more light from the tubes than the cfl's, in my experience.  Of course, I like leds the best, no mercury and all.  I hope you are doing well down there and staying warm and dry.

Hi Bill
Wow I am really impressed with the 400 Leds being powered from the EB's. That is also my goal, but 100 will do for now 


I have watched all of your youtube videos and as usual am always impressed with what can be done these days, it sort of makes me feel like we are entering a new epoch and are very close to discovering something that will change the way we carry out our daily routines

do you remember if anyone has posted any info on secondaries for the Fuji AAA or Kodak AA as I am only on page 59 of this topic and would like to get up to speed with JT circuits

The Fuji circuits have a built in secondary.  The transformer has a primary and a secondary.  There is also a trigger coil that I am not aware of anyone using as it would put out about 2,000 + volts.  This is what that large cap fires.

There is no magic to any of these circuits BUT, I do feel that folks are doing some great things that have not been done before, and they are very useful and practical things. 

Try to get an AA Fuji even if you have to buy it new.  You can use the film (or not) and then use the board.  Be advised that we learned that both the AA and the AAA come in the same box.  I always open the box to see which one it is before buying.  (The Fuji AA has the black switch on the front of the camera.)
