Hello Chris, I have a regulator working now, total cost was about $3, its adjustable down to about 1.2v. I havent tested its current capabilities yet, but the data sheets on the regulator specify that it can supply 1.5A, so for a fuel gauge it should be heaps. If you were going to use it for anything much higher, I would start thinking about fitting a small heatsink to the regulator itself. Anyone interested in the diagrams I can send them to you, just send me your address. Chris, where abouts do you live? I am in Wollongong, so if you are in the area I can just send it to you or something, otherwise you could make your own for cheap or I can post it to you.
