Apart from that, would anyone have an M. 15v Ni-Cd Charger FS?
If you know anything about electricity and solder and such, you are
probably better off constructing your own. The M.15 charger is
notorious for destroying battery packs when attached too long.
I don't know if you have anything like "Radio Shack" in .au land, but
in the US, you can get the few parts you need there.
The simplest charger would be a ~20 VDC source, an LM723 adjustable
voltage regulator integrated circuit, a resistor, and a couple of
capacitors. The voltage regulator chip is wired with feedback as a
current regulator. The 20 volt DC source is a 16 VAC transformer,
rectifier diode, and filter capacitor, or if you look around at
electronics "bargain bins" you might be able to find such a thing as
a self-contained "wall wart" power supply.
The most difficult part of the project would be the mechanical
coupling to the battery terminal contacts. Buy an M.15 charger and
cut the plug off the end. (The best use *I* can think of for this
battery-killer! :-)
If there's sufficient interest, I might be talked into making plans
available. (Bribes work great, too! :-)
