I make things.
here's a little project I've been tinkering with for a while, I always wanted to
a: get rid of the annoying speedo cable that buggers up the front end
b: not worry about how off my speedometer is, or that running a smaller rim will throw everything off
c: have a nice clean speedometer with no wires or things hanging out
d: have a speedo whose needle isn't bouncing around so much I have to do math to know how fast I'm going
so here's the solution, tiny gps module that gets a real fast fix, running into a tiny mcu that decodes the signal, figures out the speed, and outputs to an rc servo that moves a needle. once stuffed into an old speedo housing, you'll never know it's got that stuff in it, but will wonder why there's no cables
it's pretty blurry, i took it with my camera phone when driving
