A collection of hobby projects, playing with mostly obsolete technology: Classic arcade games in smaller packages, vintage computing (think 1950s and 60s), and an incomplete-but-not-abandoned attempt to build a scanning tunneling microscope with atomic resolution.
New – The
Enigma touch, an electronic model of the Enigma cipher machine, is now available if you want your own! I have partnered with Oscar Vermeulen and the team at CEDS to make this happen. The expanded pages here offer a closer look – or head over to
obsolescence.dev, home of the PiDP computer replicas, for more.
… where vintage is defined as anything from “older than me” to “my first computer”. Pocket-sized replicas of 1950’s magnetic drum computers, a mouse from 1968, and the 6502 microprocessor from 1975 re-implemented to run at 100 MHz.
Enigma touchI like old arcade games from the 70s and 80s (although I’m not good at playing them). Some of these early games generate their video display in unusual ways – by drawing vectors via X/Y control of the CRT’s electron beam, or by generating their video signal from hard-wired TTL logic.
Two projects in this section feature original circuit boards in new, smaller enclosures which showcase the boards. Also, a small MAME cabinet specializing in vertical-format arcade games from the “Golden Age”, based on a Raspberry Pi and a customized mechanical joystick.
Asteroids miniA catch-all for projects that don’t fit the categories above. At the moment, this comprises my – fairly comprehensive but unfinished – Scanning Tunneling Microscope project, a wristwatch for nerds, and modification instructions for an echo effect pedal for musicians.
