Looking for a cheap charger...

[BrianG]

Well, I made a NiMH charger for AA's that uses temperature-peaking to determine when to shut down. It works really well for the Turnigy LSD AA's I have for various remote controls and is simple to operate (it auto starts when you plug in the cells) and charges at ~400mA.

But now we have other rechargeable things, and I'd like something a little more versatile that is small enough to sit on my desk, yet does what I want. Basically, I'd be charging more NiMHs, the occasional Lixx, etc at various rates depending on how much in a hurry I am. Some cells take a better charge at low rate, while others can take a faster charge, which is why I want something highly adjustable current-wise.
