NiMH/NiCd charger.

I have a stack of cells that the auto charger refuses to charge.
BigClive had an article on what to do with them so I made a charger.

His circuit..

I just realized I put 220R resisters in and they should be 120R
Oh well. longer charging time!

I'll let you know how it turns out.

I have just finished watching Big Clive, he really knows his stuff, what a hoot, class act, fantastic presentation, I think I might try to bring my eight year old dead Bosch 18 v battery pack back to life!! .
