About twice a year I participate in bicycle hill.
I'd like to see how my performance is and review the race, but with my current bike computer I can get the data out of it.
So I've been dreaming about putting together a device that would allow me to monitor and record the data for later analysis.
Looking around I noticed that a lot of sensor projects seem to use the Aruduino platform.
So there's a lot of documentation available to search through to find what I need.
There are a couple of approaches that I'm thinking of:
1. open up my cateye cycle computer and somehow leach the data I want from it
(I have this one: http://www.cateye.com/en/product_detail/253 )
2. Just make it all from zero.
In my searches I haven't seen any attempts at building a cycle computer. I guess this is mainly because these devices are relativly inexpensive.
But I can't find a cheap one that has the features I want, so here are my planned features:
SD card data logging
DATA in ASCII text cvs format
Heart Rate logging? (this seems like it might be difficult)
LCD Display (Again, difficult, can I canabalize an old cellphone screen?)
