@kooler

Thanks for the inductor advice...make a huge difference!

Here are some pic's of the upgrade now only pulling uA and the led is brighter now!

wow...just noticed the uA pull is down to 13.7 and slowly lowering??

Kooler has this happened with your setup!  Doesn't make sence  now 13.6

yes..
that is the reason i set my at 1.5 ma and you can watch it go down from there with the same brightness..
i have one with a lr44 coin cell running that had 1.22 volts reading on it .. i got it out of my dead battery box.. haha
but its running for 34 hours it reads 1.45 volts now.. few more days will tell me more..
here is a new diagram of were i put the inductor..

trigger coils:

Just a note:  Some trigger coils have independent coils, therefore they become electrically isolated.  Winding with a higher ohmic resistance is the winding with more turns.

@ altrez

I think this is correct. Touch both cans to start. Tune by changing spacing between cans.

@all,
I mentioned last night I hadn't seen Bill posting a while, I spoke to him this morning from Australia, he is OK.

I think all the snow and cold is getting to everyone, it wont be long before you have summer and I get the cold
