Trickle Charge Circuit ??

Would like my remote datalogger to charge it's own batteries.

Looking for a trickle charge circuit to charge either NiCAD or Nickel
Hydride batteries. The circuit should work with a 6v, 50ma solar
cell. If that spec. not possible I'll buy additional or diff. cells.

Thanks, Pete.

    What would, or would there, be any differences between NiCad and NMH battery
    charger circuits.

    Would help to know the maH capacity of the battery pack
    and the expected power demand - NiCd & NiMH are somewhat
    different in their requirements.
