Good work, Lynx!

Looks like I have a lot of catching up to do.  I have been on vacation and out of touch with this project for a week.  I did have a little time yesterday to get back into playing around on the bench.  I saw this page a while back and finally got around to experimenting with the circuit.

http://tacashi.tripod.com/elctrncs/inverter/inverter.htm

I did not have any of the parts specified, but what I did have worked very well.  I used a 470 Ohm and 1K resistor, 0.047uF and 0.01uF caps, 26g and 30g magnet wire, TIP31c transistor, and a slightly larger transformer core than what is shown on the link.  18 turns for the trigger, 35 turns for the primary and 275 turns on the secondary.  With these components the current draw is 110mA using 4 AAA batteries @ 6volts.  It lights 2 â€" 2watt each LED bulbs nicely.  Will do the light box test to determine how it is performing. When using 2 0.047uF caps, this circuit will light a modified CFL as well. 

Enjoy â€" Brad S   :)

Heys guys. I wanted to ask some of the better techs here if they could design a 10 led 3.2v 24ma 30000mcd led headlamp for my scooter. I just need the best circuit with the lowest draw ever from a small battery pack. I have read all the pages and still have not been able to figure this out. I'm no expert in the joule thief circuit.


I appreciate the help guys.


Where has everyone been as of late.. Almost a month without posts???
