Hey MrNightdrive,

I took a slightly different approach to increasing the maximum readable ID number. My method uses four phototransistors in a row along the slot to extend the interaction length. Also I set up ID detection algorithms which require only two identical pulse reads to register an ID detection. The system detects IDs up to 36 at normal racing speeds. I need to measure the maximum vehicle speed for 100% accurate ID detection (especially for ID36 which is the lowest frequency) and report back in due course. It will be fast!

Thanks again for your post and interest.
