Joule Thief

@kooler Hey did you get any 1001 boards . have an interesting idea for self powered gen . Need to couple it with Tesla idea in place of the OSC.

hey man,
i have done a very similar deal once with my shop roof.. its steel and 120 feet long it give me alittle over 6 volts it took 3 weeks to charge a AA battery.. to were it held a charge.. the 6 volts was after a voltage multiplier..
it would be nice to find a way to make a higher voltage then try to use it..
i didn't get any 1001 boards i was so excited to get something for free.. i just got one demo board..

Here is my demo board. (3002)  I also now have three A 1V/1uA Ext R&C Silicon Oscillator/Timer TDFN22EP-8 (from packing list)

I do not see a chip on my board or any way to mount the ones sent.  Does anyone know?  I feel like an idiot.

PS  The packing list calls each of those 3 items a quantity of 3 each for a total of 9.  Do they come apart or something?
       STPrue, did you get something that looks like these things?

It's there Bill . that little black square is your baby! It is UI.

Pirate,

That's the sample board and sample surface mount chips I received. I plan to interface it to the joule ringer circuit using a 'NPN' transistor hooked up to the 'PWM_OUT' on the board. One of those chips is mounted on the board at 'U1'.

Hope this is not a silly question, went to the dollar store and purchased a light that goes inside a pumpkin.  This light has three LED’s that turn on and off, one after the other giving a strobe effect.  Runs off 2 AA’s so I had to take it apart to see what makes it run.  Absolutely no components to the circuit except the black blob (like the ones seen on solar light circuits) where the board runs the connections from the LED’s, and power into this central spot.  Anyone have any idea what the component might be driving this and could it possibly run from a JT.  Would be fun to build a multi light low power stobe.  Any help is appreciated.  Can post pictures later, but doubt that would help identifying part.
