Free lap counter timer and DIY transponder
Remove this ad - become a site supporter!
I've built a RC lap counter timer using a do it yourself transponder. LapTrackerTK is available free as opensource software, and the transponders can be built for sub $10. All the information is on sourceforge:
See the working concept here on youtube:
I suggest reading the wiki first. LapTrackerTK is the program I built using Tcl/Tk. The program runs on windows 32bit or 64bit, and can also be run from source in Linux with a Tcl interpreter. LapTrackerTK is fully featured and can track any number of cars. You can change the number of laps run in a race, or choose a duration of race by time. Track length is required for accurate speed calculations. You can enter meters to have speed calculated in km/h. Feet will display the speed as mph.
The DIY Transponders are inexpensive Wi-Fi modules that send their ID's to LapTrackerTK over a Wi-Fi network when they are triggered a magnet embedded in the track surface.
What you'll need:
Laptop or PC connected to a network.
Access-Point connected to the same network
You can achieve a fully wireless setup if you have a laptop connected to an Access-Point.
