I design and build — musical instruments under the Heifer Zephyr brand, open maker tooling, and a decentralized climate-data protocol. Each project ships with real engineering: CAD, acoustic models, build packets, and documentation. Browse the work below.

Studio Explorers Library

Card view across the whole instrument portfolio — filter by family, status, acoustic model, CAD, and explorer readiness. Each card opens that instrument's own design site.

Per-instrument design sites

Every instrument has its own page: an interactive Wolfram acoustic model, concept renders, a live 3D model, and the full downloadable build packet (design, BOM, cut list, validation).

WRFCoin

A decentralized protocol for verifiable climate and weather data. Whitepaper-complete and heading toward a public testnet — the goal is to put the testnet in the general public's hands.
