Shmøergh Hog – The making of a simple analog synth

The Shmøergh Hog is a newly developed analog synthesizer designed for live performance, featuring a fully analog signal path, two voices with various wave shapes, and customizable options. The project, led by Peter Zimon and his friend Flame, took about two years to reach its first prototype stage, driven by a desire to create a user-friendly instrument that contrasts with the complexity of modern synthesizers. The design process involved reworking circuitry and enclosures, with the first version housed in a metal IKEA flower pot, which also serves as a Faraday cage. The team focused on simplifying the build process by reducing the number of printed circuit boards (PCBs) and using surface mount components. The final design includes a stainless steel enclosure and aims to provide a unique instrument for each owner, rather than mass production. The Hog's design principles emphasize quality and usability, with a goal of delivering a synthesizer that musicians can easily integrate into their performances. The complete design is available for public access, encouraging others to explore and build their own versions.

This is really well documented with lovely schematics, and the link in the github to the proper "korg style" toggle switches [1] on AliExpress is worth the read.

The code [2] is very nice as well, showing how clean a bare metal Pi Pico project can be.

Thanks a lot for your kind words everyone! Zimo (author/builder)

This is amazing and super inspiring. I love how such a professional looking enclosure is actually a repurposed Ikea flowerpot—-brilliant.

Does anyone know how one would print the black text on the flowerpot? I have an acrylic enclosure from a project but could never figure out how to get text printed on it.

As a danish and german speaker, the name is hard to get used to, because it conflicts with all the lexical rules existent in nordic germanic languages. This name, lexically, does not make sense at all, also you won't find any word in nordic languages written like this. "shm" just does not exist and "øe" also is very very rare in northern germanic. On the other side in western germanic, "oe" is the "ö". So this gets even more weird. Haha. Nevermind! :-D I love such projects. Very well done! Looks beautiful. Sound is not mine, but that is a question of my bad taste.. ;-)

Cool project, very nicely done.

And Ikea Bittergurka as enclosure is a great idea for my next project.

Cool project! I understand mass producing these doesn't much sense, but would a build kit that has just PCBs with SMD components in place and the rest of work left to user work? I know someone who did a similar project and it turned out that when ordering PCBs, single one is really expensive compared to even a tiny batch.

Surprised there are so many through hole parts. Why not SMT if going through jlcpcb?

Gorgeous cases! And I love the breakdown of the process. Super inspiring work!

What are the prerequisites for building one of these boards? Can I read the GitHub and start building? Or, do I need to do some reading about CircuitJS, and tools like that?
