a lapcounter application would be great and VERY important for races.
I tried to develop a solution with rfid tags and arduino, but the cars are too fast
so lap recognition does not work properly.
The much better solution would be to sniff out the communication data between car and controller.
Real FX uses Amic A7105 chip.
Does anyone have experience with sniffing out 2.4 Ghz data, maybe with wireless module AMB2520, as Tinus said ??
