Projects Portfolio

Welcome to my project showcase. Here you’ll find a collection of things I’ve built, broken, fixed, or am still experimenting with. Ranging from electronics and code to amateur radio and 3D printing, each project tells a little story.

🔧 Electronics & Embedded Systems

Capacitive CW Touch Keyer PCB

Tools: KiCad
A low-profile CW touch keyer based on M0UKD’s circuit, modified to include copper pad paddles, an SMD TRS jack, and coin-cell power.

Raspberry Pi Mini Server Rack

Tools: 3D Printing, Networking, Docker, Proxmox
A modular 3D-printed rack to house multiple Raspberry Pi boards, a mini-PC, and a switch—my own homelab playground.

USB-C PD Voltage Selector

Tools: Schematic design
Built a switchable power output between 9V and 12V using a PD trigger board and a DPDT on-off-on toggle.
