Re: Home Brew Chargers anyone?

Thanks, I'll look on RCgroups DIY electronics forum.

I'm looking at several boost chips available and playing with circuits on 
Electronics Workbench and free SwitcherCad from Linear Technologies.  I
have 
a few inductors, microcontrollers, and MosFets to experiment with, I need
to 
get a boost controller, Schottky diodes, and higher voltage capacitors.

I have commercial chargers but I don't have any that I can write custom 
programs for.  Right now I would like to add a feature to keep liPo's at 
storage voltage and automatically charge them to be ready by the date and 
time I select(ie Noon Sunday, or next spring).  I could do the electronics

to make my Triton a 4 ****t charger but the program would have to be
modified 
to switch batteries in and out of the charge circuit.  Since the Triton,
or 
any commercial charger I know of, isn't user programmable, I'm attempting
to 
make one that is.

Thanks!
