During these years I’ve designed and built a multi-FX pedalboard for my own use. The latest iteration is based on a Raspberry Pi 4 and a custom audio interface.
The goal was to get a full guitar effect processing within a single box, with additional expression pedals. The footswitches can be configured to do almost anything (toggling an effect, activating a full effect chain, changing parameters…)
Here is the page describing the project in details. You’ll also find exhaustive building instructions, user manual, pictures and audio examples.
Of course the drawings, schematics and source code are 100% free and open source, so you can use and modify them to your liking.

Wow, very impressive. Thanks for the hi-res images! Did you cut and drill the sheet-metal yourself?
Is the audio interface based on an off-the-shelf codec? I can see a TSOP on the audio interface board but I can't make out what it is. Did you design/layout the main and audio interface boards yourself?

Ah, I just saw that you used a Cirrus Logic codec. A very interesting project. I will read more about it!

Yes. Everything was done at home, excepted the PCBs. I cut the sheet with saws, but it was not very easy. I had to do most of the work with a small handle-saw (I don’t know how it is called), and bent or broke a couple of blades. The windows for the display and some connectors were cut with a rotary tool (Dremel-like) with a cutting disc. The holes were done with a standard drill and different kinds of bits.
I designed most of the audio interface layouts, but borrowed and adapted some schematics from Uwe Beis. It was helpful for the differential gain stage, output, clock system and the power supply. I also followed some application notes from the IC datasheets.Is the audio interface based on an off-the-shelf codec? I can see a TSOP on the audio interface board but I can't make out what it is.

Very cool and well-built project! Much tidier than my DIY efforts, I have to confess
Congratulations!
Congratulations!

Very nice work, I struggle to get a simple overdrive pedal finished so in awe of your dedication to this.
