MFOS Weird Sound Generator in SMT

The SMT adaptation was a hobby project. The MFOS designs are the property of SynthCube.

Here comes my next conversion of Ray’s classic analog synthesizer, the Weird Sound Generator!

Eurorack version of MFOS Weird Sound Generator, with prototype laser etched front panel

This is the same process as for my previous SMT/Eurorack conversion of the Sound Lab Mini-Synth. The circuit is identical to the original, including component references.

MFOS Sound Lab Mini-Synth is a cool analog monophonic synthesizer. The original version has been created by Ray Wilson from Music From Outer Space.

KiCad 3D Library – BOURNS-3296

I’m updating all my current designs in order to incorporate WRL/STEP 3D models. They provide a convenient way to check mechanical issues, especially with cases and front panels.

Bourns 3296 Trimpots
The Bourns 3296 3/8″ Trimpots are missing from the official KiCad 3D Library, so I decided to create my own.

It’s also a useful way to learn how to use FreeCAD and Github.
I’m also using kicad StepUp for model conversion, alignement and scaling.
