I have been using KinT controllers in my Advantage2 keyboards. However, I have been a bit worried about the availability of Teensy MCUs. I have been using Teensy LCs, but they are pretty much out of stock until 2024 and may never get in stock again. Teensy 4.0 and 4.2 controllers go for 30-40 Euro, which is pretty insane in a world of 4 Euro Raspberry Pi Picos.
At any rate, I'd like to keep some spares in case one of the controllers breaks. Moreover, I have been wishing for USB-C, since I am a Mac user. Luckily, /u/dj_edit made a KinT fork that uses the Black Pill microcontroller that is readily available for a few bucks and best of all has USB-C.
So, this week I got the PCBs and converted my first Advantage from vanilla KinT to KinT Black Pill:
I also ported their Vial support over to QMK, which required some changes to work with the latest QMK (mostly porting over stuff to info.json):

The USB-C mount is one from the series of mounts that I found on Amazon and discussed in this Reddit post
I had wrist pains every now and then over the years. They never felt bad enough so find a doctor, so it never had a specific diagnosis.
Then I had a worse brush with wrist pain I decided to try several split keyboards (Microsoft Sculpt on and off, Kinesis Freestyle Edge, Ferris Sweep, Kyria) and they didn't really improve things and sometimes gave me new pains. Only after switching to a Kinesis Advantage2 I saw large improvements and wrist pains mostly going away.
I also started to be more mindful of taking breaks (sometimes it works out, sometimes I am so focused that time flies by) and do some hand exercises during breaks. I also got an easily adjustable standing desk (just a press of the button), so I can tune it to have exactly the right height and switch between sitting and standing.
