Happy New Year! Tronbike 1.x is riding reliably and is almost normal. The meter is the most unreliable component, gently prodding me to work on the new solution I am calling TBM2.
So far, this consists of a small ARM board computer running Linux. Getting the included kernel (2.6.13) to properly support my personal myriad of USB devices has been the goal, and last night finally my USB-WIFI device, a Linksys WUSB 11, finally made contact. The GPS works over bluetooth, and I have cross-compiled the "gpsd" to make access to the data "standard". Storage devices/USB memory sticks thankfully work right out of the box.
I should confirm RS232 support, either using my Keyspan USB-serial dongle or the built in RS232, but that should be easy, right ;)
NOW the hard part begins. I need to either port/install PythonGTK to the new platform OR port the TBM1 guts into C and cross compile. The GTK on the iPAQ gave me graphics, so more than a C port, I would need to use perhaps the board's included "QTopia". Because I have WIFI, another idea is to just create an iPhone application for the display system, and bury the current board within
the bike. I also could run the TBM2 as a network host for TBM1 on the iPAQ, using "usbnet" or even WIFI.
Besides the USB options, the distro on the ARM9 is pretty sparse - the "Familiar" distribution for the old iPAQs is far superior for usability and features. "Familiar" linux has an entire packaging system even.
Porting/supporting Bluetooth on just the right ancient iPAQ still might be the path of least work to getting something useful on the bike.
