elctronic cronograph

[cableguy]

Hi to You all.

I'm gathering ideas for a electronic cronograph capable of counting from 0,001 up to 5 min.
It is intended to be used as a "stop & go" controler for a slotcar rallye circuit, and shoul also have a way to set the number of laps to time, give the time of the best lap, etc....

Any ideas??



Thanks

Check out my website which has a circuit to time Pinewood Derby cars. It measures .01 second to 9.99 seconds, so some timeing changes would be needed, and it times 2 cars, but it could be a start.
You have to copy and paste the URL because geocities does not allow links. www.geocities.com/russlk
Well, I tried the link and it works, so I don't know why sometimes it doesn't.
