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.

Is there any 5x3+3 dactyl manuform? (except skelety)
Check https://github.com/stars/manna-harbour/lists/36-keys, but I don't remember one with a closed case. Still, I can't imagine open cases breaking easily. Also you could ask u/Beheddard if he's planning a closed case for dometyl / choctyl sometime.

Creating a custom 36 key split gergoplex / ferris sweep style board?
Here's a list of open source 3x5+3 keyboards. Many are choc spaced. Some are also diodeless, but that limits your choice of MCU and ability to mod. Diodes aren't difficult to solder, and SMD turns out to be easier to deal with than TH.
