Thanks for you fast response, so a few things to think about ill get a multimeter on an old power supply and just have a look at the step down transformer voltage, you never know 12 volt? stability of the battery could maybe be sorted with a second battery and some split charging switch or something similar Dig out a really old motherboard to test the thing on Would a better solution be to use an inverter to go back to 240v first? I guess the best solution would be to get hold of a laptop, but i never was one for easy solutions... Thanks again

Hi I was wondering how easy it would be to set up a desktop pc to run from a 12v car battery. If a desktop power supply is 12v, 5v & 3.3v could it be as sinple as getting some chunky resistors in line to drop the voltage? To utilise ohms law and work out the size of the resistor you would need to know exactly what your power consumption was going to be so i guess that is out of the question as it must vary depending what you are doing at the time. Anyway has anyone had any experience with this or am i way off track? Thanks in advance.... Robbie OK another quick thought, if you actually started the car the voltage would jump to 13.5.... Doh

We have vending machines that use a programmable key instead of money, i guess if you could find out which chip it had in it you could read and reprogramme your credit level? Other than that i guess your going to have to stick to hard earned cash
