interesting daisy project on github

[zgrav]

found this interesting Daisy pedal project today while browsing github. stereo and midi in and out, 6 controls and an OLED screen in a 125B enclosure.

I had a set of those made for the 125b enclosure with the pcb designs (and surface mount part instructions) in the repository from JLCPCB and the one I put together works well. I had issues with the screen so I hooked up a 4 pin I2C version of the screen, changed a tiny amount of code and then it worked.

That repository is really nice since it gives you the pcb design, the files required for JLC to assemble most of the parts, and the instructions on how to submit things. Even if you are not building that exact pcb, it is a good resource for how to submit pcb designs and assembly instructions to a fab house.

I can confirm that the 125B OLED model is a really cool platform for developing effects! The creator reached out and mailed me one for prototyping. It really is remarkable that he shared the entire design as open source, I've only scratched the surface of what's possible with that unit. For anyone wanting to learn KiCad, smd manufacturing, and coding, this is a great project to jump into. It's also a good resource for KiCad footprints common to guitar pedals.

Here's a picture of it:

Oh hey cool! That's my project, glad you all found it helpful! I'm pretty active on the Electro-smith discord and forums. If anyone ever has any questions about the project, I'm, happy to answer. I'm also looking for contributors if anyone wants to help on the hardware or software side of the project.

That's a really cool project!
I for one, I'm down with screens for daisy applications. Wish I could code, but not realistically going to happen, but will be checking it out. And great ressources put together as I'm learning KiCAD this year and gearing to have my first populated pcb produced.

Thank you! The screen is super helpful! I also have a 1590b sized version of the project with 4 knobs and no screen. It's cool too, and can be done with all through-hole parts, but I find myself using the 125b one with the screen more often.

Creating this pedal project was my way to learn KiCad and learn as much as I could about electronics. I had never really done this stuff before, I have a programming background, so I'm by no means an expert on circuits or hardware. I spent a ton of time watching tutorials (Getting to Blinky) and learning the basics of KiCad. The cool thing about Electro-Smith is they share their schematics for the hardware. So I started by re-creating parts of the Daisy Petal, as they called it, in KiCad and then over time started modifying it to add some of the stuff like the screen etc. It was a fun multi-month project, learned a ton. Decided to put it all on GitHub because I hope others find it useful, can learn from it, or will contribute to it. I'm still tinkering with it, but it's awesome to see others have built their own stuff based on this or have had my pedal manufactured to use. I love that!

For anyone else that has one of the 125b oled pedals, I wrote a reverb/delay effect module that I’d like to share, you can get the compiled binary here: https://github.com/GuitarML/DaisySeedProjects/releases/tag/v1.0

It’s a stereo reverb / delay that has tap tempo control, reverse, octave (and reverse octave similar to Reverse Mode C pedal), modulation, triplett/dotted 8th taps, routing option, filtering, basically everything I could think to throw in there! The c++ code is on my fork as well for anyone interested, it’s the “reverb_delay_module”: https://github.com/GuitarML/DaisySeedProjects/tree/main/Software/GuitarPedal/Effect-Modules

Oh and all the parameters should be midi controllable, haven't tested that yet, need to get some new gear!

Here’s a video I made about this pedal and some effects for it, you can get any of the effects from the video in this release: https://github.com/GuitarML/DaisySeedProjects/releases/tag/v1.1

The code is also open source in the various branches of that project, if you wanted to adapt it to another Daisy Seed based device.

I literally just watched this video before I saw this post -- very cool stuff.
