Brian Wampler has published a new course at his guitarpedalcourse.com site. It’s called The Complete Beginner’s Guide to Building Digital Guitar Effects - No Coding Required, and it uses Faust running on the Daisy Seed.
( Note: if you have strong opinions about so-called “vibe coding” [using AI to generate code from descriptive text], you’ll need to bite your tongue like I did 
)
In the course, there is a module that walks you through building a three-potentiometer pedal from scratch, complete with audio buffer schematic, drilling template, BOM, strip/vero board layout, wiring diagram, etc. However, if you don’t want to mess with all that stuff, PedalPCB created a custom Terrarium PCB for the course. You could also use a Funbox or a Hothouse.
If you use a Hothouse, you’ll be happy to learn about the faust2hothouse script that comes with Faust. It compiles and deploys Faust programs to the Hothouse with a single command. I worked with Brian while he was launching the course to ensure all of the examples run on the Hothouse, and wrote a wiki article for anyone interested.
