Smart Pullup Bar (2017)

On my previous team, we liked to have “pull-up standups”—after our status meeting, we’d take turns on the pullup bar, keeping a whiteboard tally of our personal records.

I built a sensor and record-keeping system for our office pull-up bar. You scan your work badge, then it counts your pullups and adds them to your record.


  • Raspberry Pi with touchscreen LCD.
  • Wi-Fi connected with web UI
  • RFID badge reader
  • IR proximity sensor
  • 3D printed enclosure for the Pi and badge reader.
  • 3D printed mount for the IR proximity sensor, to attach onto a GoPro gooseneck arm clamped onto the pullup bar.
