I plan on keeping this laptop in my glovebox. I want to build an autoconnect tray that will basically clamp around the lappy when i get in the car and hold VGA, USB and Ethernet connections solid, but allow easy install and removal so it is not permanently installed in the car. I will need to create a custom power control system using WOL ethernet capabilities, an asus car charger and a few 12 vdc relays. Will give that system its own line item in the future.

Will mount in stock double din in WRX. USB touch screen control and VGA video input will come directly off of lappy. Powered via 12vdc from Battery.

Trendnet USB to Serial Converter:

This will basically plug into my Wideband O2 sensor controller which should allow me realtime PC side O2 readings. Will more than likely plug directly into USB Hub.

Tactrix Openport 2.0:

Will be used for Datalogging and Flashing my ECU via Romraider (www.romraider.org) and ECUFlash (www.openecu.org) Will plug directly into USB port on computer to avoid COM issues.

Startup Controller System:

I will basically be running a single 12 vdc dpst relay to turn on power in acc and on key positions but leave it off in off and start key positions so that cranking voltage and current spikes dont get sent to the computer. the second pole of the relay will contact pins 2 and of 6 of the ethernet port while pins 1 and 3 are always connected this will resume the compy from standby using the wake on lan (WOL) function. I am also using ShutControl to control the automatic standby function.

USB Hub:

I decided i am going to run a Macally 7 port externally powered USB hub. I feel external powere will be important as I plan on running a fusion brain and an external sound card in the future.

Frontend:

I was originally gonna run a version of RideRunner for a front end that an AWDPirates member(surtr) had created, he had already embedded enginuity(romraider) to display engine data scrolling across the display but I belive i'm gonna nix that and go with sawmill resized with winamp running on top.
