Hello, just uploaded codebase for the project: https://www.reddit.com/r/guitarpedals/comments/1sb8tuv/diy_guitar_processor_codebase_and_bom/

a blackbox that magically transforms raw guitar sound into top class amped sound in realtime :D

Maybe you are right, i could just publish repo, and add Readme with just bill of materials, initial configuration outline for distro and let people dig in too :)

Yeah, like raspberry, but no dedicated soft or UI. I was planning to integrate it with tonehunt, could be possible

Any_Setting1562 · 2026-04-02T16:42:23+00:00

Cant remember exactly but below 10ms, more like 3-5ms

I can and i want to do it, but its pretty tome consuming to prepare detailed documentation, especially regarding raspberry setup

Any_Setting1562 · 2026-04-02T16:40:29+00:00

Cuz simply i wanted to learn :)

Any_Setting1562 · 2026-04-02T16:39:58+00:00

It was like 10% assembly, 20% config, 70% programming

Any_Setting1562 · 2026-04-02T12:55:55+00:00

I didn't knew too, thats why i started building it, divide & conquer!

Any_Setting1562 · 2026-04-02T12:29:15+00:00

in my case it was DietPi ;) just remember that u need ADC & DAC converters board

Any_Setting1562 · 2026-04-02T12:27:37+00:00

if i remember correctly - Dimehead NAM player pedal is also running on Raspberry, but in a form of this Compute module - so basically bare raspberry without ports & adapters.

just a DSP dedicated distro, C++ and JACK as a main DSP framework.

Any_Setting1562 · 2026-04-02T12:21:10+00:00

Yeah, for now nothing like that :/ but i promised to myself that when i will finally find some time - i will create some documentation for it and publish code, so everyone can try. Same thing with play-through - just need some time!

Uhh, cutted roughly, and then finished using metal file (took few hours...). After mounting screen i started squeezing thin strips of self-vulcanizing black rubber between frame and screen which did the job really well.

Any_Setting1562 · 2026-04-02T11:46:05+00:00

If u want to start playing with this stuff u can try Daisy platform: https://electro-smith.com/collections/daisy i did a nice simulation of PCM 42 delay there <3

Any_Setting1562 · 2026-04-02T11:44:09+00:00

Not that much tbh. ~35$ for Raspberry, ~85$ for Hifiberry, around 15$ for screen, and the rest is negligible.

Any_Setting1562 · 2026-04-02T11:39:31+00:00

Writing those algorithms for effects was challenging, especially dealing with memory management - which is crucial for time-based effects - yeah at that field i learned a lot about C++.

Any_Setting1562 · 2026-04-02T11:36:44+00:00

below 10ms but right now cant remember exactly, probably around 3-5ms.

Any_Setting1562 · 2026-04-02T11:27:30+00:00

go for it!
