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 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. 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 ...
