get thee behind me, satan

Ever since I briefly lusted over the Garmin 305 bike computer, I've been thinking about what it would take to build my own ultimate bike computer. It all seemed like it was going to be a lot of work, I'd probably use a fairly slow microcontroller, a text LCD with an integrated controller, I'd have to write a bunch of interface code, maybe even a filesystem to write to a some sort of CompactFlash[Wiki] or similar card for logging...

Then today something got me to look at Gumstix, and... GPSstix adds a USB client, stereo audio in/out, a GPS receiver and an LCD controller to a basic 200 or 400 MHz computer with an MMC slot for storage that runs Linux[Wiki]. Tie that to a 128x128 color cell phone display, a gig or two flash card, and with a little client software I could have scrolling color maps while every measurable aspect of my bike, body and route was logged for later review.

Right now the only thing keeping me sane about this is that I don't have hard numbers on power consumption, and "< 250 mA" implies "you might get 4 hours out of a set of NiMH AA cells", otherwise... I really don't need a project like that right now. I really don't need a project like that right now. I really don't need a ...

How many buttons they got? I've actually got a PalmV lying around here somewhere that would also make a decent platform, but part of the allure is the idea of something that anyone can build, and that has a boatload of IO capabillity (said Palm, if I set up an alternate power supply system, only has a serial port and a few buttons, where I'd really like some good interrupts and a few decent A/D converters).

Buttons? A whole Qwerty Keyboard. And a CF slot for WiFi, Camera, and I think there was a GPS thingy.. http://www.serialio.com/products/adaptors/GPS_BR305_Z6.htm was the first link. It has serial, IRDA.. Ethernet/WiFI and SD cards and a CF slot. A nice screen, and it plays MP3's.

There is also a CF Card reportedly supported.
