[dorkbotpdx-blabber] bike clock

[tim kochanski]

I built a bike computer with an old pda, some magets and a serial port from radioshack.  do you want the clock to count seconds as RPM's or do you want the ol' skool clock to count seconds as Km or miles?  You could have the magets send a pulse to a device that counts clicks then turns on power to the clock at approapriate intervals.  the math part is just arithematic.  getting all the mechanical doo-dads picked out would likely be the tough part.  you could prolly program an arduino for such a task.  then it's just an arithematic programming problem.  I am imagining pulses of electricity to the clock to advance it at intervals appropriate to your distance traveled.  Sounds interesting for sure.
