Joule Thief

[Pirate88179]

@ Jeanna:

Well, 100 of my led lights are colored, the other 100 are clear.  Yes, I believe I could easily read with the 100 clear ones.  But, when I tried just 100, they were very bright, maybe too bright.  I figure that each string is made to run on 120 volts from the wall so, if we are putting out 300 volts, I needed to run the second 100 to keep the others from frying.  This is why I think I can run another 100 for a total of 300.  These could all be clear leds which would be very, very bright.  The leds in the Christmas lights are the very small ones.  What I would call a "regular" led is 5mm in dia. and the large superbrights I used in my earlier joule thief experiments were 10 mm.  So, I am guessing that these small leds are maybe 2.5 mm?  Would it not be cool to run 200 leds from the earth battery?  I am going to get more Fuji circuits to play with as I am sure to blow this one out sooner or later.

I have one more question for the electronics guys here.  You have all seen my Fuji board as modified per instructions.  There is no cap, and I removed all of the other components as instructed.  Today, while wiring to my led tree lights, I got zapped yet again....a pretty big jolt.  Funny thing is, I had not (on purpose) put the AA bat. in yet while I was fooling with it.  It had been sitting on the top of my fridge over night with no battery installed.  What is left on my board that can store power like that?  Is it that silver crystal can?  Or the transformer?  The only other thing on there is a resistor and I know they can't do that.  Again, this zap was about as good as I got off the cap while removing it.  I am baffled by this. I now handle this board very carefully, with, or without a battery installed. (yes, I can learn quick)  My guess is the transformer but I have never heard of this effect before.

That silver thing is actually a capacitor (probably 0.02 uF). If you had gotten zapped with the fully charged large 100 uF cap (5000 times more energy) you would probably have a small hole in your finger. That is why I suggest removing it.

ok im impressed bill lol 

when is some one gonna try and CHARGE A BATTERY  SO YOU ALL CAN HAVE OU 


LOL

2 tests charge with hv rectified via  a 1n4007 diode ....

and carge with out a diode

try a car battery 

i hear deep cycle just love rf / re ..... 

ist

to hook 2 jt's togather i would make 2 almost the same    1 npn 1 pnp  and i might try reversing the wind...

found a great vid lol   http://www.youtube.com/watch?v=er4F4BIUAfY

is that an aa battery in there .....   must be 1 hell of a TUNED COIL

to do that...

Thanks.  Nice video.  Yes, that appears to be a single AA battery there.  What was he doing or trying to do?  The flash was impressive but the noise was even better.  That was a lot of power seeking equilibrium in a very short time I think.

Interesting idea you have for linking 2 jt's together.  What do you think will happen?  Do you think they will be synchronized and achieve some sort of resonance?  I guess there is only one way to find out.

@xee2:

A cap?  wow, I didn't know that.  I thought I read somewhere, maybe on Jose's site, that this was a crystal for tuning or something.  If it is a cap, well, that explains it.  This thing has zapped me every time I fool with it it seems.  I try to be careful but.....zap!  Also, I did get zapped with the large cap while discharging it for removal.  It probably was not fully charged up (thank God) but it was still a good jolt.  Maybe one day I will learn.

Don't know if I posted this one before or not.  I guess I am still excited by lighting 200 leds from a AA battery.  If this is a repeat, I am sorry.  I will make some more soon and hopefuly they will be in focus. (I will use a tri-pod)
