What I've read posted here has made sense, and would probably be a good guide, 
but for me, my 'luck' has not been good with homebrew chargers.  In Vietnam I 
was toying around with charging some Military NiCd 'discards', and had a great 
setup for charging them until one night the alarm went off.  When everyone 
grabbed their gear and ran out someone bumped the table where I was charging a 
set, and after we returned from the alert the building was on fire.  The 
commander wrote it off that we had taken a hit, but when I saw the melted 
remains of the wiring and bulging, split cells, I knew better, but kept my 
mouth shut!  Years later I built a similar setup in my garage, but one night 
either cats or rats knocked things amiss, and the transformer, cells, and 
rectifiers were found in the morning in a heap of melted down trash.   :-((

I never got around to building a rigid structure for keeping all the parts in 
their proper places without the risk of having things fall over and shorting 
out.  Those cells have far too much amperage available to take shortcuts, so I 
finally played safe and went commercial with the little "AA" cells and 
chargers.

If you look for 'commercial', the key is to be SURE the charger will take ONE 
to 'x' cells.  Any that advertise charging 2, 4, 6, etc., aren't worth having 
unless you want to spend most of your remaining years trying to 'match pairs'.  
:-((

 JP>         Your thoughts ?

Nahhh!  You don't want my thoughts, too dirty!   :-))


     Good luck...  M.
