Component specifications
12/17/2014 at 16:11 • 0 commentsfor the displays themselves I chose the RHP7.
These were chosen because I saw a picture of the inside of one of the units and saw that they had a lot of extra room and it looked fairly Hackable.
They also turned out to be a good balance of size and cost.
For the hard wired controller I chose a super Nintendo controller.
This doubles as a Control for XBMC and also for the emulators which I will be adding to the system.
For the infrared input I repurposed the infrared receiver on the monitor itself and redirected the output pin to the raspberry pi
I had originally thought of running the audio and video down to the center console and putting in a composite matrix switch so that they could share video sources if wanted
After I looked at that possible solution I realize it strayed from my goals of having a easy to use standalone unit that would operate on only 12 V if The rest of the infrastructure of the car was inoperable
The only other active component that I have in this build is a UBEC it's output is 5 V at 5 A. I have used these in the past and I know that they operate at a wide input voltage, such as what will be present in a car.

The project:
12/17/2014 at 15:33 • 0 commentsMy requirements for this project are as follows:
The unit must be able to operate in standalone mode, requiring only a 12vdc input
Optional remote control interface, but the primary control is hardwired
The hardwired control is preferred to be cheap, easy to replace, and be hard to kill (preferably no USB controllers)
Keep the BOM count to a minimum, less parts means it should be less likely to have a failure (in theory)
Be able for a kid to operate it intuiatively
Be able to handle getting power dumped without warning
Resume playback as fast as possible once power is restored
Be able to play games
