302 5V out
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. -T8
