The 3V battery Charger uses
a DIY Kit (Kit 135) bought in Ap Liu Street for
just $55.
The Kit is originally designed for 12V input step-up to 16V output. Some modifications to the circuit are required (Ra & Rb) for charging the Palm safely at 4.09V.
The Kit's PCB is quite large.
And you need to connect a Hotsync adaptor to connect the Palm.
