Winterbloom introduces Micronova: a tiny but mighty Eurorack power supply
I'm glad you enjoyed it! We're serious about open source and that means we gotta be serious about documentation. If you want a really fun one, check out https://gemini.wntr.dev ;)

How do you build your source code?
We use ninja - a very small and fast build system. Ninja generally needs something to generate its build files (CMake, Meson, etc.), but we just use a little Python script to generate ours.

Matriarch, modular, and Felt Instruments
Winterbloom also has something similar with their interactive user guide for Castor & Pollux (their latest Eurorack-format synth module). It's geared towards beginners and explains a lot of things that are useful even if you don't ever plan to get that module or any modular gear at all.

Small/unknown Eurorack makers?
Plus the modules are really cool and unique. Sol and BHB are both programmable with CircuitPython. All the hardware and firmware are open source for all the modules. Thea is also suuuuuper good about documentation too; check out this interactive user guide for Castor & Pollux!

Duophonic jam with Castor & Pollux, a juno-inspired dual osc
C&P is the latest, and most complex yet, by my favorite indie module maker, Winterbloom. I pre-ordered as soon as it was available to do so and they finally started shipping recently. The manual is pretty sweet and really interactive and educational too. RMR did a really good video demoing the wide range of sounds this can produce; highly recommend checking it out.

Anyone help Compile and Program MCU for Castor and Pollux for trade of PCBs
Hey there, I wrote some build instructions in the contributing guide on GitHub: https://github.com/wntrblm/Castor_and_Pollux/blob/main/CONTRIBUTING.md#building-the-firmware

Here's a Juno style DCO I just made
This is great! I love a good minimal implementation. If anyone is looking for a complete Juno-style DCO, you might be interested in Castor & Pollux- the module that I wrote that Juno article for. It's also completely open-source, and you can find the schematics and source code here.

Portable Signal Generator?
Are you trying to build your own nanoVNA? There are many different versions of the nanoVNA on the internet, google "nanovna source" and see how they implemented the signal generator part.

Survey: Help us design a VNA for hobbyists and professional users
Wanna do the community a favor and fork edy555’s repository here? Study the issues and comments in the repo along with the NanoVNA’s complaints all over Amazon. Coming up with these decisions on your own might serve to be vastly more valuable than letting the community tell you what to do.

Where to get a good NanoVNA v3? I'm fine with copies. I just want it to work properly.
I bought mine from Nooelec. They're listed as an official distributor on edy555's GitHub repo.
