Actually it is not a laptop. It is a Pentium 4 @1.5GHz with 128mb RDRAM and 46GB Hard Drive and DVD-ROM Drive.
If you are slightly familiar with building computers it is no problem to do. I put a power converter in to get AC to run the computer. You could actually do without it and bypass the computer's power supply since it is designed to run on 12V and 5V but going through the power supply is a good idea since it is regulated.
In my trunk in the spare tire space I mounted the motherboard down using screws to secure it in place. The boards (video, sound, ...) are installed in the motherboard and the speaker output is connected to the amplifier inputs via a cable you can pick up at any Radio Shack for a couple of dollars. The monitor I purchased from EarthLCD.com. The unit is designed to run off 12V plus it is touch screen and displays 640x480 at 16-bit. It was the most expensive piece in the system. The hard drive is mounted in a small cage with foam padding to dampen as much of the vibration as possible. I have been running it in my car for one and a half years with no problems.
The rest is just having the right software. I am running Windows XP (which I worked as a developer on at Microsoft for a year before moving to Idaho). I am using freely downloadable MP3 software for playing back my files and have written an interface to allow me to quickly select any song I am after. I have also recently started adding to it the ability to make it voice activated.
And with the addition of DVD palyback software I can watch DVD movies in the car. I also have another piece of hardware that allows me to pick up radio or watch television.
The final piece of the system is a hand held GPS device which interfaces with the computer via a COM port and I have Microsoft Streets & Trips which communicates with the GPS device and gives me a fairly complete road map of the entire US.
If you have any specific questions regarding install just post another message or e-mail me at [email protected]
. I will be glad to give you as much information as I can.
