The RiscPC powersupply is noisy even after removing the fan. (buzzes). My approach would be to use DC power and bypass the psu. I'm not sure what chips use the -12 and -5V lines but they may be OK with batterys and an alternative charger or solar panel. The other thing that springs to mind is the use of alternating current from the car alternator to drive a +/- psu. Just a few ideas... Cheers -Ron You must Sign in before you can post messages.
