The Brass Thumb Pomodoro is a steampunk-style desk timer that rewards a completed 25-minute work session by popping a thumbs-up figure out of its case. A side switch selects work or rest mode, with five-minute breaks between sessions.

Maker Krzysztof Jamroz built the USB-powered device with Arduino electronics and 3D-printed parts. Assembly instructions and code are available on GitHub.

Rock-a-Pomo is a Pomodoro timer that starts crying when a work session ends and will not begin the break until the user picks it up with both hands and gently rocks it. A few seconds of appropriately gentle, rhythmic motion gradually fills a soothing meter; once the robot is calm and smiling, the break timer begins.

A single hard shake does not work, and rocking it too violently does not increase the meter either. The enclosure is deliberately large enough to encourage two-handed use so the user has to let go of the keyboard and mouse. It was created by nabekura.
