About Ken Shirriff

I'm interested in computer history and reverse engineering old chips. I am currently restoring a Xerox Alto.

Some projects:
Wrote the Arduino IRremote library for infrared remotes.
Attempted Bitcoin mining on a 55 year old IBM 1401 punch card mainframe.
Got six symbols added to Unicode including the Bitcoin symbol (₿).
Wrote an article on the first microprocessors for IEEE Spectrum.
Gave a talk on reverse-engineering old integrated circuits at the Hackaday Superconference (YouTube).
