Help me power my laptop carputer...AUX line in noise when I use inverter
So I took apart a apple G3 iBook dual usb laptop and i plan to use it as a carputer. Everything was going smoothly until I went down to buy a inverter so I could plug my laptop in. As soon as I plugged in the laptop to the inverter the AUX line in went to crazy static! It was so loud and annoying. I've read about inverters doing this and causing noise to peoples system. So what are my options for power now? What are these DC to DC regulators or whatever. Could someone explain this to me. What are my options here to power my laptop without all this damn static noise interference. Take in mind that this was a 50 dollar 500 mhz laptop so I would like to keep this as cheap as possible. Help!
