For all those fans of the Satcure circuit, here I believe, is the 2 transistor step-up circuit mentioned on the Satcure Bead thread.
I hope someone will look it over and try it. I don't have all the parts in my junkbox and I'm not sure right now what transistor would make a good substitute for the one originally used. It looks like a pretty easy circuit to breadboard and test though. http://dustbin.virtualave.net/circuits/led1v5.html
