[RE-wrenches] Programmable Battery Charger

[Jerry Shafer]

Very interesting, what diodes did you use to rectify the AC, it sounds
similar to the wind machine designs I have worked with. Do you use a coil
to regulate the AC amps to the diodes, it seams like you would need a
"throttle control" the current someway besides the diodes them selves or
the CC.
