Completely lost when it comes to power supplies
I am working up plans to turn my Gateway 7415GX laptop into a carputer. Its a fairly fast laptop with a AMD Athlon 64 3000+ processor, dedicated ATI 9600 64MB vid card and soon to be nearly 1TB of HDD. Plenty for a carputer
I want to mold in a 7-9" monitor in the lower dash of my Explorer where the current waste of space trip computer is. (say OBD-II and Dash Commander Light). I also want to power a compliment of USB's with bluetooth, a Blu-ray USB drive mounted where the stock HU used to be, GPS and, well, everything else you can think of. Oh, also will be adding a USB based Sirius Sat Radio. I want to run all of the audio through an external high quality (Sound Blaster) external sound card to my Arc Audio EQ/Line Driver and out to my amps and speakers. This will create front, rear and a sub channel off a stereo input with 9v output and low noise floor. The audio section is already installed and sounds superb as its designed to be an SQ rig. I am good with car audio.
I am good with computers in office settings but get them into a car, avoiding a DC to AC converter which we always used on short trips, and well, I am lost.
I have read 100+ posts and visited many DC to DC manufacturers but for the life of me cannot understand the whole concept. My laptop appears to not have a "docking station" so I am forced down the hard path. I kinda get rewiring the laptop shutoff switch but with so many features involved I get lost. Seems to me it would be so much easier if their was a "box" that was wire into the 12v system (heck, I could pull power and ground from my distro system). Into this box we could plug all of our add ons.
Don't know what my question is. I am sure I will figure it out. I have built some sick car audio systems but so far am lost. If you got a nugget or tip or roadmap then hit me up.
Never thought wiring a soon to be mostly dismantled laptop would be so confusing. I will stop as its late and I am rambling.
