From the project

Firmware for a wireless single-operator officiating system: a pair of wrist-worn referee remotes and a USB dongle that bridges them to a browser-based scoreboard.

Firmware for a wireless single-operator officiating system: a pair of wrist-worn referee remotes and a USB dongle that bridges them to a browser-based scoreboard.

A conventional grappling mat needs a referee, a scoreboard operator, and often a towel tapper to signal the referee when time expires. This system lets one referee run a complete match — clock, score, and the one or two ruleset-specific states that matter — with no table support. Expiry is felt on the wrist, which replaces the towel tapper directly.
