Projects

Things I’m building & learning

A collection of what I’m making—from hardware prototypes with custom PCBs to software experiments. I share projects honestly as they develop.

Hardware

I build hardware projects spanning CAD modeling, CoreXY 3D printing, custom PCB design, and embedded firmware. Here is a look at what I’m making.

A dedicated study timer with a custom PCB

PomodoroPebble is a small Pomodoro timer I built to make focused study sessions easier. Using online timers on a phone or laptop often led to distractions, so I decided to build a physical alternative. I designed a custom PCB, modeled a smooth 3D printed pebble enclosure that fits together with magnets, and wrote the firmware for an RP2040 microcontroller.
