- The project is a dedicated 30-second timer built around the Adafruit Trinket M0, designed for use with an Aeropress coffee maker.
- It features a simple electronic design with a button wired to ground on Pin 0 and a piezoelectric buzzer on Pin 1.
- Originally planned for a laser-cut wooden box, the final design was 3D printed using OpenSCAD for better integration and durability.
- The timer is USB-powered, simplifying the design by avoiding the complexity of battery power and charging circuits.
- The code includes visual and auditory feedback: a blinking Neopixel LED and buzzer chirps to indicate button presses and timer completion.
- A power-on LED test ensures functionality, with the code provided inline for easy replication.
