hi all, first post on the grovy new forum! (i used the old one a while back)
i drive RC cars, but i don't want to fork out £100+ for a decent charger, as i have a perfectley good power supply. but to charge at any decent power i explode batteries (done it before, whole garage was filled with black soot). so i thought, could i make a peak detection module for the power supply? it would need to detect a 5mv voltage drop that happens when the batteries reach full capacity. i think a thermal one would be easier, but i am unsure of the codeing. what is the input measured in? is it just degrees centegrade? so i could just tell the mosfet on the power to switch off when the temperature reaches 40 degrees C? or is it a more complicated method?
thanks,
joe
P.S i only did on project using an 08 chip in DT. i was top of the class for that though, just don't expect me to know too much.
