There are chips (can't remember the manufacturer, there is one major specialist) specifically for NiMh and NiCd chargers which detect the delta-V fully charged voltage step from the battery. There are also chips specially designed for charging LiIon of course.
'Intelligent' chargers (i.e. ones which detect delta-V) for NiMh and NiCD are so cheap nowadays that it's almost certainly not worth DIY except for one's own satisfaction.
Thanks - I had in the back of my mind something larger and more comprehensive than the usual 4-cell charger - something like 16 bays.
I have a ten bay one which was very reasonably priced, quite a few people sell them, mine came from CPC.
I also have a 4 x anything bay charger for the few C and D cells I have, from 7dayshop.
