Physical Computing

Bridging the gap between software logic and physical atoms.

The Olympic Loop

This isn't just a souvenir; it's a data visualization. On August 31, 2024, we hiked the Olympic National Park loop—a grueling 21.4 miles with 5,030ft of elevation gain.

I wanted to capture that effort physically. I exported the raw GPX track from AllTrails and processed it using gpxtruder.xyz to extrude the path based on elevation data. The result is a to-scale physical artifact of the journey.

SenseHAT Snake Node

Bare circuit boards are messy. I wanted my Raspberry Pi "Snake Bot" to live in the living room as a piece of decor, not a prototype.

My wife (the design lead) took this from concept to reality. She measured the hardware with calipers, sketched the constraints, and modeled the final snap-fit enclosure in Fusion 360. It hides the raw cabling while perfectly framing the 8x8 SenseHAT LED matrix.
