The lap counter is still in developement.
Previously I wrote that it didn't miss a lap in 4 hours of testing. However, I tested further by putting more than one transmitter on each car to simulate very close racing. It still didn't miss any laps, but certain combinations of two would register a third car that wasn't there. As unlikely as this scenario may be in real racing, It is unacceptable to me.
I am currently rewriting the code and using a bi-directional link that will eliminate any errors.
I don't own a 1/64th car, I will have to get a few to start on a system for them when the time comes (I have a lot going on already). The low voltage and small size will be a challenge and it probably wouldn't end up much cheaper than the bigger system, so it may still be priced outside the range of these small cars.
I don't have a final parts list yet. The transponders and the host controller are all running Atmel microcontrollers(very small computers) that are useless without the software that get programmed into them. The infrared link is now done with irda transceivers.
There seems to be some interest in the system, I will post any progress made as it happens.
