hey prabbit. how about this. it seem skinda easy if you could find a certain part.

-a tomy lap counter counts laps, but we want a straight line. -what about measuring a distance that a prabbit special car could run (without having to much speed wobbles. maybe a 5 foot distance (or how ever long the break is in between the tomy lap counter counts laps, so if it needs 2 seconds between lap counts and your car does 1 foot/sec, then it has to be at least 2 ft long) – now for the fun part, open up the counter and find the sensor wires and run a second sensor with it, selectable with a momentary switch. -of course you need to make the wires as long as the measureddistance is going to be.keep the original sensor in the counter at the finish line. -put the other sensor in a housing at the start line. -keep the switch somewhere another person can easily hit.

bottom line. you hit the go button on the counter(with the switch making the 2nd sensor at the start the one that works when pressing the momentary button). then after the start beep from the timer, you start the car way before the line so that when you hit the start, the car is maxing out. someone watches the timer and super super quickly takes note of the time when you pass go and collect $200. as soon as the car passes the start, the switch person lets go of the momentary button so that the original sensor at the finish is now functional (as long as the switch between the sensors does not trigger anything which would nullify my long idea that many are getting bored of reading already). now, the time person records the time when the car passes the finish line. subtract the start line time from the finish time. now you got your seconds it took to cover that distance. now do the calcs to get your desired foot,miles/sec or kilometers/sec. blah blah.

-of course ifthelap counter allows you to use 2 sensors without a switch, this would be even easier to do.

-if this don’t work, the idea 2 is buy 2 lap counters, set them up a yard/meter apart put a yard/meter stick across the top of the counters and push down the yard stick to start the 2 counters at the same time. this should be more fool proof, but you gotta make sure the beeps are at the same time to ensure that they are N-SYNC!!!!!! haha.

-area of concern, make the reflectors as narrow as possible to make this accurate.
