Car Computer

As part of my electrical accessory redo on the Toyota FJ Cruiser, I am converting from a Laptop to a full blown car computer. The systems is going to be mounted under the passenger seat. The Router will be mounted at the back of the FJ.

Right now I am bench testing the system to be sure all the components integrate as I want them to.

Listed here are all the parts that I am using for this computer build:

– Mother Board ECM-5716 with 1.4 gHz Pentium M. (I purchased this board on eBay from a surplus supplier).

The board supports: On-board Video, 6 USB 2.0, 2 Serial as well as a number of features that I am not going to use.

– Lilliput 10″ touch screen with native 800×600 but will support 1024×768 for a few apps that I run that need that res

– 160 GB IDE hard drive

– Mini-box M4-ATX 250w power supply. This is an intelligent Car PC power supply that has a USB interface


– Bluetooth network adapter

– Logitech diNovo Mini Bluetooth Keyboard

– CAR2PC interface to the FJ Jammer – Provides use of the steering wheel controls for media playback

– OBDII Computer Interface – Provides for PC based diagnostics of the FJ and functionality like the Scanguage.

– Linksys WRT-54G running DD-WRT – This router is going to be installed with 2 antennas on the roof of the FJ. With DD-WRT running I will be able to boost the radio to 300mw. The Router will be setup as a WIFI client bridge.

    Wow! Pretty soon your FJ will have more electronics than a jetliner!

    Keep up the good work!

    Everything looks great, I have been looking into a carputer had a few questions. how does the ham radio option work, also the client bridge router what are you using to access the internet? also plans for a sat radio or fm radio?

      I currently do not use SAT radio and I am continuing to use the Car Radio. I may add a tuner at a later date for convenience. For Internet access I use my cell phone tethered or I connect the system to a linksys running dd-wrt. The HAM Radio application is for position reporting.
