About

Interested in computer history and reverse engineering old chips. Currently restoring a Xerox Alto.

Some projects: Wrote the Arduino IRremote library for infrared remotes. Attempted Bitcoin mining on a 55 year old IBM punch card mainframe. Got six symbols added to Unicode including the Bitcoin symbol (₿).
