ok Since I officially able to order a bunch of different free samples from Fairchild, I was wanting to take the 12v output in a Car Cirgarette lighter and take a old GBA Car plug, rip out all the parts past the positive and negetive lines, and attach a Voltage Regulator to the Positive line and keep the Negetive line on the Board, (Or should I ground the Negetive line?) and then Wire it up to a plug that I can plug into the Back of my PStwo.
If its sounds like I dont know what Im talking about just tell me.
But What Voltage Regulator would be the best to knock 12vdc down to 7/8 for the PStwo to run on, or will a 7805 work just fine?

a 7805 is a 5v regulator.
a 7808 is more what you are looking for (8 volts, I hope you see the pattern)
For running off of a car battery, a linear reg like a 78xx is the simplest solution. theres so much power available that you dont need to worry about efficiency - a DCDC converter just introduces complexity you probably dont want or need.
Or, an lm317 is an adjustable linear reg that covers the voltage range you want.
As for negative/ground... they are the same thing. And yeah, you need all your grounds to be connected together or else nothing will work.

If you don't see the pattern, you aren't alone, it took me forever to notice it.timmeh87 wrote:a 7805 is a 5v regulator.

Here is a guide for making a 7808 out of a 7805.
