This is what I'm working on. I had a soldering attempt which failed so this is it on the breadboard. From left to right:
Sparkfun Venus GPS (10Hz)
Sparkfun Arduino Pro (328 3.3v/8Mhz)
Parani/Sena BT module http://www.sena.com/products/industrial ... th/esd.php (there is a buysena.com from there)
Sparkfun AD345XL 3 axis Accelerometer
Dimension 1A efficient switcher 3.3v supply http://www.robotshop.us/dimension-engin ... tor-1.html
J1850 goes in on D8.
Valentine V1 Radar Detector data on D9 (the 39k resistors in the background enables this).
This is to go with a miniGPSD project I have, mainly for Maemo (nokia tablets) but runs generally under Linux which decodes the Harley stream into RPM/Fuel/Gear/Turn-Signals, etc. state. I have an unreleased update which works with this AVR based system. Before I was using an OBD-II (OBDPros bluetooth) and direct uart to bluetooth radar detector connection (at 19.2k baud the pulses work out to distinct characters), but one BT connection is better than 3. Right now I have a couple of Python GTK/Hildon displays, one for radar (fronts window when radar present, lights screen), and one for the harley dashboard. Minigpsd itself has a link to google maps and a weather radar display located where I'm at. (I have a PHS-350 and now a Mifi so I have internet, then there's my phone with ttl serial via the headset jack - Motorola C168i, but that would be for SMS - from someone else's gpslogger).
All GPL. The updated stuff will be posted when I get a chance.

The AVR merges the GPS stream with Kxxx,yyy,zzz hex from the accelerometer (100Hz), Vhhhhhhhh from the radar detector, and Jaabbddee...cc from the J1850 stream off my Harley.
(Edit- make pic a URL) The pic is 1.2Mb (from a 12 megapixel cam) which shows everything but is huge:
