Yes, finally I got the build guide ready on my HW github repo: https://github.com/thpoll83/PolyKybd

I wanted to wait for my first batch of pre-production displays to be showcased in the instructions (along with the regular soldered ones, you have the choice) so there was some delay. The first batch:

Around 500 displays, all with long enough FPCs to directly connect to the socket! No more FPC-toFPC soldering needed :)

With that, the build guide is finally out! It contains a lot of pictures and was more work than expected. If you are impatient and you do have a hot-air rework solder station, you can go ahead and start putting a PolyKybd Split72 together :)

If you don't feel confident enough for the FPC soldering part or you don't like to buy all the different parts across various sources from the internet... Stay tuned! As you may know from previous post I'm trying to put a kit for PolyKybd Split72 kit together, just don't expect it next month or this year for Christmas.

And I can also tell you that the new displays are much smother in operation compare to the old ones, where I extended the flex cable!

What else happened?

Besides a little summer vacation (yes I need a break from time to time too) a VERY similar project came up: https://www.kickstarter.com/projects/daptkey/daptkey-redefine-your-life-with-a-customizable-keyboard/description

They "had" the idea withe the OLED displays in October 2022🤔

Not sure what to think about it. They use James Brown's mechanical solution of a separate slot in front of the key switch and the flex cable comes out at the bottom edge of the key cap. I do wonder if there is any mechanism implemented to reduce the OLED burn-in? From the video, I would rather say no. Granted, the look of the case and caps have a nice finish and these guys moved quite fast from development to production.

What are your thoughts? Let me know in the comments below!
