Hi. I'm no electronics wiz, not even an apprentice of much. But I created a circuit to finish draining off my old AA batteries that don't have enough juice to power my other electronic devices. Perhaps I'll call it, Battery Squeezing Flashlight. ha Anyway, the point is, I wonder if there is a way to control the voltage coming out of the batteries automatically. I tried to read up on voltage regulators in Wiki, but I'm confused.
I'm going to try to load a picture of my circuit. Right now, i'm using a potentiometer and a volt meter to adjust my voltage to 3.6 V (or just under) before flipping my switch on. It's not a real handy way of doing it. I may install a volt meter into the circuit for convenience, or maybe some type of componet that will light up at abot 3.5 or 3.6 V so i know when I've got the correct voltage. But I'm hoping someone can tell me if there is an auto way to regulate the voltage to 3.6V.
By the way, in case you didn't figure it out, I got a 4 pack of dead (or at least too dead to do anything else) batteries for my cells. I guess this circuit will drain them down to about 0.9V each before the lights start dimming. (As long as I keep adjusting the resistance when my lights dim too much.)
