Hi All,
Just made my first working Joule theif today following instructions in
**broken link removed**
I measured the current in the circuit coming from the battery to be 40mA, I then added another led in series... and it again showed about 40mA.
Can anyone let me know how this whole thing works, I read about it on the site and it explained a lot but I have listed the questions I have below - maybe someone knows,
1) How does one bump up the amount of mA available - ie how do I bump up the current in this design?
2) as The current seems the same after I put 2 LEDs in series does that mean that the coil will keep powering X number of LEDs in series? What would be the max, anyway to know mathematically?
A lot of these questions probably stem from the fact I dont really know about coils/transformers.
Cheers
Peter Dove
