Intelligent ni-mh charger.
This charger will charge 2-n ni-mh batteries using the delta-V method. Will charge your ni-mh batteries safely and efficiently, with safety timer. when charge is completed, it will switch to trickle charge, to maintain cells at optimum level. Remember to add some sort of cooling sink to the LM317, otherwise it will release the magic smoke, that all electronic components operate by. You can use this as an universal charger, but beware of the voltage divider, it must be adjusted to the max voltage of the charge voltage for the cells.
