Here you’ll find a collection of things that I do, make, say, and think. It collects projects published across my sites, including custom-built guitar and hi-fi amplifiers and effects, custom PC servers, and rescued or upcycled hardware. Simply a central place to collect what I’m doing with some of my creative energy at any given time.
