# Devan Metz > Projects by Devan Metz, including Goop Troops, OpenFloat Archery, a DIY electric bike, and hand-painted 3D prints. ## In short I build browser games, hardware, software tools, and 3D-printed props. This site brings together my projects and posts about building them. I’m Devan, a student and maker. I build software and physical projects, from browser games and bow sensors to an electric bike and printed instruments. I made Goop Troops, built a belt-drive electric bike, and printed and painted props from Rust. I also built OpenFloat Archery, which pairs a sensor on the bow with a browser dashboard to review its movement. My interests include Blender, Python, Arduino and Zephyr, CNC, RC, e-bike projects, YouTube, and 3D printing and painting. I’m open to internships, collaboration, and commissions. A 3D-printing store may come later. These files contain the published portfolio, project wikis, and blog. Each project document includes its canonical web page, facts, full text, image descriptions, and available video captions or transcripts.
