Step 8: Supply battery Power
Have you ever envied your friends' sweet touch screen systems in their car? Do you look at the dash of your old and decrepit 1992 Isuzu Rodeo and dream of having a slick computer system in your car? Well, your in luck. This Instructable will be your guide on building a system that is low cost and easy to build; it doesn't battery even require special tools.
The goal of this Instructable is to create a easy-to-build car computer based on the Raspberry Pi. It does not require special tools and very little knowledge of the Raspberry Pi. I chose not to use advanced tools like 3D printers or laser cutters because, while many do have access to these machines, I have been turned off of projects in the past for using such "out battery of reach" resources. battery
The CarPC runs off of a Raspberry Pi Model B running Xbian, a version of XBMC made for the Pi. The touch screen is resistive which, while not ideal, keeps cost down and is easily available through Amazon. It has the capacity to play music, watch videos, look at pictures, play games, and much more.

Okay so we're going to make a senior project with touchscreen (the one that you used) and raspberry pi b+ but as i read, you could not use touchscreen function with b+, therefore switched to b model. Is this a generic issue or are there any people who could achieve using this touchscreen with b+ model. Thanks for sharing your project which is going to help us on our senior project, best regards. battery

I do think it'd be pretty cool if you added a USB wifi module so every time you go home, it syncs up with some media server sitting in your house and downloads updates automatically. Combine that with the battery idea a few comments down, and as soon as you turn off your car and wifi is in range, it syncs everything up and shuts down automatically until you start your car next time.
Yeah, It totally is not the safest for the driver to be operating, much like normal GPS/Media centers in cars.
Controlling windows and door locks is a bit ambitious (though not impossible), but adding an audio receiver and amp at a minimum would be great -- and solve the problem of moving the original radio. CD-ROM takes up a lot of room... and I don't see is as necessary as the radio. Convert your CDs to MP3s and you're good to go! Takes some time, and you can't listen to a CD right after buying in the car, but that's only a slight inconvenience. Not having a radio built-in is more inconvenient. Can't listen battery to local news/talk radio, or for a bit of variety. I really don't use my CD player any more, just a USB stick with 300 or so songs on it. Usually use the random play feature of my Kenwood receiver, but sometimes drop to radio for something different.

I purchased an Anker 5000MaH battery and ran the Pi off of that and let the car charge the battery battery (it can charge and discharge battery simultaneously) so it gave me clean power 100% of the time. It also allowed the Pi to run about 4 hours without draining the car battery.
Car power when running can be 14 to 17 volts pulsed battery DC. There may also be spikes from the ignition system. There are many off the shelf solutions that involve large capacitor and coil combinations. Without putting an oscilliscope on the DC power line it is hard to say what caused the issue.
That is very interesting. That must depend on the car as mine seemed to work fine. I am still a little worried about the screen as I wonder battery if it could surge somehow, but it is fairly cheap to replace if it does. Wiring is not my skill set.
It is actually something experienced by all cars. A lot of rectification and filtering goes into most automotive electronics to clean the power up. Typically, DC power from a battery is very clean, it just slowly decreases in voltage as it drains. However, in a car, there are so many random things drawing a lot of amperage at various times, plus the alternator charging the battery with a varying speed, based on the engine's rpm. As mentioned, it can be cleaned up, but a cheap linear regulator alone is definitely not capable of doing that. Otherwise, this is a great project. I would definitely look into friendlier xmbc skin interfaces so you are less likely to crash the car. A lot of people have mentioned controlling other parts of the car from the RPi - this wouldn't be too a hard to do - just use a transistor to drive 12V relays with the Pi's I/O. A few scripts battery can be written to do it, but I don't know how you could incorporate the control into XMBC. Also, I would not recommend battery removing the stock functionality for anything (windows, locks, etc) just in case the Pi crashes - no way to roll your windows back up! You might al
