The speed trap instructions in the Cities and Transportation
sets show a way to set up two photo gates.
The RCX is programmed to record the time between
the first sensor reading is lowered to when the other sensor reading is lowered.
Changing the gearing on the capacitor car can make it too fast to pass the test on the speed trap
or slow and strong enough to climb up the bridge.
Instructions are given on how to be a Teleoperator.
Two teleoperators in two rooms.
Those Fair rides really move!
