Welcome to e‑basteln.de!


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.

Arcade Games

I 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.

Vintage Computing

… where vintage is defined as “older than me”, or at least “back when I was a kid.” ;-)
Pocket-sized replicas of 1950’s magnetic drum computers, and a mouse from 1968.

Other Projects

A 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, and modification instructions for an echo effect pedal for musicians.
