I need a curcuit board made.

I would like to make a 2 luxeon III light thats regulated and has multiple output levels. The problem is that I know nothing about constructing the board for myself. Is there someone here that does this, or a web site maybe? /ubbthreads/images/graemlins/confused.gif Also, is this very expensive to have done? Please, help a newbie out. /ubbthreads/images/graemlins/help.gif Thanks

You need a Fatman current regulator from George at TaskLed.

The fatman sounds great. I could use 3 luxeon III's or 2 luxeon 5's. That is the kind of output I am looking for. Thank you.

Your other option is George's nFlex. Both boards are truly excellent, you can't go wrong with anything he makes.

I'll second that. His customer service is beyond anything you could imagine.

what he said.. george is amazing.. he helped me 're engineer' the fatman to suit a very very particular need i have in a prototype light i'm building.. i was able to swap resistors on the board with my pot.. i can't imagine better customer service than that.

nFlex is a buck ckt, so not as likely to be used in a mag mod, though some people have.. by using 123s or the AAA to D adapters etc..

fatman has a pot input for dialing down the brightness with a built-in minimum.. there is even a fairly ugly hack to add on low-voltage protection (ugly because the light will blink at the end.... though in the last couple of tests.. it actually dims to about 1/8th normal output beforehand so you definitely know the battery is dead).

I started a whole thread once "I love fatman".. great driver.. trying to work it into my minimighty light.. it's stunning.

I would like to add a comment about George also. When I email him the answer is back in a flash. When I order, it's shipped in a flash. I have not used the Fatman yet, but if it is even close to his customer service then it can't be beat. Many businesses would do well to take a lesson from George.

I cant wait until more Fatman's are available.
