The insides 🥹

Hi! I’m a mechatronics student and this is a prototype I’ve been working on for a while: a Pomodoro timer without a screen. I call it the Cube (yes, it's actually a hexagon).

Every 5 minutes one of the leaves pops out. After 25 minutes they click through a reward sequence and the orange one comes up for the break.

Inside there’s a PCB I designed myself with an external microcontroller board, 6 solenoids to extend the leaves and a push-pen latch for each leaf (resin printed). The housing is 3D printed too.

One thing I can’t figure out: the click is too loud for a library. Ideally the volume would be adjustable. Has anyone done something like that with solenoids?
