I am making a time-trial race timer so my club can keep track of their practice times. Someone has to manually do it, taking them out of havinga yarn; and for online tournaments usually someone smashes their best time without it being recorded so doesn’t count.
There’s
- an esp32 powered LIDAR “gate” to start/stop a lap
- an esp32 powering a display (giant 7 segment display made out of neopixels)
- a raspberry pi that acts as an mqtt broker, and relay to the internet
- a website to track and manage all the times
When motivation strikes I’m planning on adding:
- a camera system to the Pi to record and evidence times
- a RFID system to track riders and vehicles, so it can be fully automated.
One of my devices uses three keys because out of the two local servers I have, they seem to go down every other month, so I need a failover.
