Hello everyone, I've salvaged a stepper motor that puts out a couple of volts when being turned at a reasonable rate and would like to use it in a battery charger. I have a varying voltage and current depending on how quickly I'm cranking the motor, so I'm thinking I need to construct a voltage regulator to keep it at 1.2V per battery and a circuit to cut off charging when the battery is full.
The trouble is that I'm new to working with batteries and I don't know the details. For example, I'm not even sure whether or not it's a problem to be using a voltage a little higher than 1.2V per battery, and I don't know current I should try to maintain, or how I should determine when to stop charging. Any help would be greatly appreciated!
