Help building a racing timer using walkie talkies

[grafgulch]

I have a crazy idea about building a racing timer using a pair of kids
walke talkies. The timer would be actived & stopped by running over a
tape switch. I have a pair of kids walkies talkies thats has a morse
code botton on it. I was thinking I could somehow wire the tapeswitch
to the morse code botton and have the tapeswitch start a clock timer
and when I hit the next tapeswitch this would stop the timer. I don't
have any electronic experience and am willing to learn, but has
something like this been done before?

No, because it's a really dumb idea. Just run wires alongside the track to
the other tapeswitch, and sense the switch closures at your timer box.

It shouldn't take more than a few seconds to find something like an
electrically-activated timer switch by google or so.

That should be a start.

Good Luck!

Thanks for the advice Rich. I am full of dumb ideas BTW.

Why is that a dumb idea? Is it any "dumber" than buying several
hundred feet of wire on a spool, rolling out the wire, making sure the
wire doesn't get torn out of the switches at the beginning or end by
passers-by, and then rolling up the several hundred feet of wire--
every single time you want to use the timer?

Instead of insulting the person who asked, is there any chance that
you--or someone else, preferably--might instead address the intent of
that person's question, which seemed (to me) to have been, "Is such a
thing technically possible?" Sheesh...

Yes, of course, it's technically possible, but to the problem of keeping
passersby off the wire, you add the problem of keeping passersby from
stepping on your transmitter, keeping the transmitter and receiver tuned
and filled with fresh batteries, designing some kind of signaling system
that encodes the switch closure at one end and transmits that information
reliably to the other end with minimal time delay, preferably calibrated,
and all the associated hardware mods that would have to be made.

I'd rather string a wire while I'm policing the track, and put up "PLEASE
DON'T STEP ON THIS WIRE" signs.

But, it's your call.

Good Luck!
