Does anyone know whether the 302 uses an (efficient) switch mode DC
converter, or just a plain old regulator (doubles as a toaster)? I'm
idly wondering if it's worth my while to wire in a separate switch
mode power supply for the PDA -- you can get good quality DC/DC
converters that run with 90% efficiency for five or six bucks.... If
the 302 uses a regulator (as I suspect) the increase in battery life,
or power available to do other things, would be substantial.
