The Attenuverter

Greetings, Earth creatures! And welcome to "Electrical City", a new blog i have started to document some of the electronic music projects i have been working on.

Here is a video showing my usual process of building a Eurorack synthesizer module, starting with finding a schematic on the web, building the circuit on a breadboard, then on stripboard, based on a design created from the schematic, testing, and finally cutting and drilling a front panel, and assembling (the soundtrack is also all original music so hope you enjoy that ;-).



This particular module is an "Attenuverter", based on a schematic by skullandcircuits.com. An attenuverter is a utility module for attenuating or inverting signals, so it's a potentially handy signal management tool, where those signals could be audio, or voltage (haven't tested this one yet with voltage, but it would be interesting to see what happens).

The Skull and Circuits resource page is here. Here is the stripboard layout, designed with DIYLC (the jacks are on a separate board).
