I designed this machine (https://neutral-labs.com/elmyra/) which may interest some of you. It's a design not unlike the Lyra-8, but I had Vlad Kreimer's blessing to create it.
You can (more or less) easily build it yourself. All the info you need is on the site, even etch masks for the PCB and an SVG if you like to create the panel yourself (though I'm also offering PCBs, panels, kits and builds).
Here's the build guide (https://neutral-labs.com/wp-content/uploads/2020/03/Elmyra-v.1.1-build-guide.pdf).
Curious to know what you think, and if some of you would like to build it, I'd be honoured.
