Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Ordered an assembled STeMCell, but can't put it into uf2 bootloader mode. Am I missing something?
I ordered a pre-assembled STeMCell MCU. The dfu bootloader works, and I was able to flash the uf2 bootloader onto there, but i'm not sure how to put it into uf2 bootloader mode. When I power the MCU on while holding the BOOT0 button down, it goes back into dfu mode. Am I missing something?

My rapidly accelerating pursuit of ergo
in the meantime, we've been using stemcell controllers which don't have the same issue

Why the strange keyboards?
And I do agree that ESD issues are often overblown, but since I gotten my hand on some STMCELL back when pro micros were hard to get , I had to think hard about esd protection as "This design does not have any fuse, esd protection or reverse voltage protection." https://github.com/megamind4089/STeMCell

I feel like I could overload these even more…
stemcell, but you need to build it yourself.

Pro Micro Crashing Oled ?
Your promicro is not enough program memory(32kb) to use some animations, let's use another controller which have more program memory like stemcellhttps://github.com/megamind4089/STeMCell

The blackpill is not, but the bonsai c4 is, alongside the stemcell, if you're JLCPCB-wise

Creating a custom 36 key split gergoplex / ferris sweep style board?
There are a few controllers that have the additional holes (puchi-c, goldfish, comet etc) not just the elite-c. StemCell is probably one of the more open ones and you can get them assembled at jlc I believe? https://github.com/megamind4089/STeMCell

Is AVR not enough for QMK nowadays? I'm struggling with firmware and EEPROM size and can't enable all the features I want.

00Key a 75% Keyboard
I only use keyboards running QMK or ZMK, so:
My Caps Lock key is a Control/Escape key (when tapped it behave like a Escape, when hold it's Control), and my left Control is a one shot layer switch key [1], which means I tap LCtrl once, and then press Caps Lock + 5 to get Ctrl+F5. Doable with single hand and more ergonomic as I have an unusually small hand.

Principles for Keyboard Layouts (2022)
I agree that reduced finger movement is a crucial step in achieving typing efficiency. This is nicely solved by mod tap modifiers in QMK/ZMK[1] where key acts as a char when tapped and as a layer while pressed.

Debugging a Failing Hotkey
If you have a keyboard that runs QMK firmware[0] with the VIA[1] feature enabled[2], then there is a convenient testing app available from the same place you customize your keys [3].

Just setting up my first corne layout. It will take a while for me to get used to this wow... It's taking so long to type. Attached is my layout, and I mainly use c# on visual studio. Any concerns/advice/suggestions are welcome. It will take a while for me to reply on this thing though.. haha..
I made a layout that I'm happy with. Spanish is my native language, so it has characters like the accents and 'ñ', but it's meant to be used for programming as well. Visual Studio uses a lot of Ctrl and Ctrl + Shift shortcuts, so I left them in the same place as the default Corne layout so I can press them both with my pinkie finger. Perhaps some of the ideas are useful to you.

Adafruit Feather RP2040 with USB Type A Host as a QMK converter board?
Also, it would be possible to do this for the RP2040. However, it needs some work to get working. but for example: https://github.com/qmk/qmk_firmware/pull/20999

If anyone knows of a good tutorial on how to make this tft display useful on a board controlled by an rp2040 and flashed with qmk configurator, I would be most grateful if you could point me in that direction. Gracias!
Ok, it's an ST7735, not too different from the ST7789. You should be able to get running by looking at their files in the QMK repo and going from there. You should also check their resources page.
