I'm a beginner in electronics but I want a better nimh charger without having to spend alot of money. I came up with a simple cirtuit using 2 lm317.
supply voltage goes into input. battery plugs into output. I would manually time it based upon mah.
I could also plug the battery into aux and use the second half to drain battery and measure mah.
Is there anything I'm missing? I'm mainly going to be using it for 6v battery packs, but occasionally higher. I'm not planning on charging over 500ma. I am curious on how could I know if it's charged not based upon time.
picture showing example. the little boxes are circuits
