Fianlly, i can do it, 2 mode PCB can be use VIA ( you can use VIA website for keymap when you use Bluetooth Mode )
Spec :
- MCU Nrf52840 ( e73 module )
- Firmware base on QMK
- 3 slot BLE 5.2
- led indicator for USB mode +bluetooth device number + battery status available

I often skip lines because the keys on my keyboard are too close together, and it's very annoying.

Hello, this is MWKEYS, today we bring you Milkyway's first dual-color keycap - MW Lilith R3.
   In the past two years we energetic order surge, deep cooperation Vendors bankruptcy, order decay a series of tribulations, but this did not break us, in the past year, we developed dual-color products, and optimized our heat sublimation products. This allows us to have a better guarantee of the quality of our products.

Omg you're the best!!! They came out awesome, you did great and thanks for doing it so quickly.

Edit: would you be able to send a version that's bigger? Maybe around 480px wide?

Sure, here you go.

Howdy Limentic! I registered to be able to comment! I've been working on a mechanical magic keyboard since May 2022 (yeah I know I'm slow). I'm slowly working on a write-up, but I should have been releasing incremental updates as you've done! I searched again on a whim (since nothing came up in 2022), and your post came up. The dedication to scan the matrix and hand-label it is nuts! I created a PCB with several mux chips (CD74H) so I can just scan the matrix while I press each key. I used a full-sized one as a few others have done, but I'm using Gateron low-profile switches to try and keep it similar to the trackpad I have at work. I intend to have the numpad detachable and able to clip to either side with magnets and pogo pins, but I think I'm still a ways off.

Anyway- long way of saying awesome job and thank you!

Thanks Matthew, scanning the matrix using mux chips is also a good approach to the problem, but because I'm kinda broke, cheap, and I don't value my time The hand-labeling process of the matrix seemed like a good idea at the time! (And I am very proud of the beautiful wallpaper I've created in the meantime )

Good luck with your keyboard; I even think you will be done before me
Doing a Masters in EE and working on side projects don't mix very well, lol (who knew, right?)

I randomly remembered your Post on LTT Forums and decided to make an account here to express my support for this huge undertaking of such an interesting project! I love mechanical keyboards and Apple's Magic Keyboard, so seeing someone trying to marry the two is such a damn cool concept!

Thanks, man, for taking the time to make an account just to post on here (thanks Matthew for that as well) just to show support! It's nuts for me to see this niche project getting so much attraction; I am so grateful for that.

I wanted to reply to both of you guys, to first, reply to you, but to show that this project isn't dead, and I really want to finish it, but the only thing I lack is time, really. Sometimes, you wish you were a YouTuber, right?
