Hardware

Building a local LoRa mesh network using Meshtastic — solar-powered repeater nodes and handheld devices for off-grid, encrypted, peer-to-peer communication that doesn't depend on the internet or cell towers.

A Raspberry Pi 5 laptop built into a cigar box. Dual 7-inch screens, salvaged laptop hinges mounted to pine two-by-four, Kano keyboard, junkyard energy. Actually runs Linux.

Repurposed 1970s slide viewer, Raspberry Pi Zero, NASA API. A retrofuturistic passive info display.

A Python script running on a Raspberry Pi scrapes Shepard Fairey's print archive, converts each image to 7 colors, and displays it on a color e-paper screen. Built fast, with parts already on hand.

A hand-built e-ink ereader. Waveshare 7.5" e-paper display, Raspberry Pi Zero 2 W, rotary encoder, UPS battery hat. Reads epub and CBZ. Built from parts already on hand.

Added MIDI input to a 1982 Yamaha CS01-II analog synthesizer using a Highly Liquid UMR2 universal retrofit board. Involves soldering, the service manual, and a transposition quirk baked into the keyboard layout.

Arduino-based add-on that reads CV/Gate output from the TB-303 or TD-3 and generates a PWM square wave oscillator — fed back into the synth's filter input for phasing and wobble effects.
