2007 Dodge Caliber - Grizzly's WiFi touchscreens
I've been working on this project already for more than two years, and changed the plans a few times along the way.
Beagleboard ARM Cortex development board
5 inch touchscreen via S-Video
1998 Chevy Caviler
Sadly the car was in a wreck and the build never got off my bench.
I bought a 2007 Dodge Caliber (used) and moved on.
BestBuy Infocast 8" touchscreen, custom firmware, flash frontend.
This build never got past GUI design, and I was spending far too much time on the UI and not enough on the backend to run it.
BestBuy Infocast 8" touchscreen, custom firmware, remote desktop client.
Dell D420 Laptop
Modified Dell D-Port Mini-Dock (Added remote power header, USB WiFi accesspoint)
DCDC-USB Powersupply w/ Dell specific plug from a universal powersupply (has the ID chip)
Sony head unit with Bluetooth
I'm running WindowsXP, RideRunner, Garmin Mobile, and Pandora. I added a RaLink WiFi adapter inside the D-Port, and SoftAP drivers for XP. The touchscreen (I plan to add a second one for passengers) connects to the laptop via the SoftAP network. On the touchscreen I'm running the stock kernel from chumby and Ubuntu 9.04. For controlling XP I'm using rdesktop which is an RDP client. I'm still building a controller to interface the sony unilink bus to the laptop for control & status, and to enable the aux input on the back. The controller is based on the Propeller chip from parallax, and will also handle talking to the two ultrasonic rangefinder "parking sensor" kits.
I've got a 3ft x 2ft x 6in wood box I built to hold the backend hardware in the cargo area of the car. Two inches of foam line the bottom to dampen vibrations and other movement, and the entire box is covered in twill kakhi fabric, matching the interior of the car. The box will be physically strapped down with a twill colored belt material, which is also used to secure the laptop inside the box (in addition to the latches on the dock.)
Right now I'm waiting on the belts for the laptop to get back from my sister (who is generously sewing them for me) so that I can finish upholstering the box.
I also have to finish bondo & paint on the dash insert before it can be used.
I hope to finish the project in the days / weeks ahead, so that I can enjoy the finished product on my drive to MakerFaire in NYC.
