I built and installed a lap timer for an indoor BMX pump track. I explain a select type of photoelectric sensors and the basic operation of a lap timer.
Many thanks to Mike and the owner at thewheelmill.com
Cost to build: ~$280. The two pairs of sensors are the bulk of this cost ($220).
Sensors used: Omron E3Z-FTN11-L
