It's a bit sad how deserted this community is, would love to connect more with other makers.

Let's rattle the cage a bit, who of you is here, and what are you working on?

I'll start: A wireless cryptographic keystore & signer. Keys are generated with the hardware RNG and stored AES-encrypted with the user's password, and you can request signatures via BLE.

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.
