Has anyone set up a solar charger for the Zaurus. Most of the out of the box charges produce 5v at 500ma (OK for palms I believe). What would the impact of using a lower current on battery life/charging time be? Any guidance would be appreciated.

Smaller cells won't take longer. I have tried this setup in the past. The problem is that no load the regulated output from my panels was 5 volts. However when the charger switched in the output dropped. This results in a on-off-on-off blinking of the charger light which is not a good solution.

Using 4 NIMHs as an energy store over time for the panels is probably the best way to go with smaller panels, unless you have a panel which will do 5 volts (make sure you regulate it!) at 1amp. BTW switching regulators are recommended... Can turn 12volt 500mA into 5volts 1Amp.... good luck.
