When products evolve over time they tend to adopt technologies as they emerge. Not this project however, as it seems to embrace only disappearing technologies. It started with not-so-recent OTA’s and even more old-school germanium diodes, this time the designer managed to replace the output opamp by a 3046 transistor array. This famous part from the seventies of the last century, obsoleted several years ago, has been reintroduced by Texas Instruments a few years back. Extrapolating the path this project is going along we may expect version three to be built around tubes and rev 4 out of wood and flint.

Another interesting aspect of this project is its description. While most authors explain their project in a few lines, leaving a lot to guess for the readers, this poster has gone through some trouble of writing things up.
