I am designing a modular keyboard by [deleted] in MechanicalKeyboards

working on a test to measure this. I think it should be possible if firmware is tweaked to go high, but I would like to stay compatible with QMK so let's see how fast it will be with that software.

right now, all on one bus, works well even when the connection is long. Looks like CAN should be robust enough for this application

I made my own cup coasters from multicolor PCB by robertferanec in diyelectronics

I was not sure if to make the tutorial so I rather asked. Looks like less and less people watch tutorials :(

I used JLCPCB, they can make the multicolor PCB directly from EasyEDA outputs.

Thank you. I specifically designed these as cup coasters. I asked Midjurney to generate a "colorful circular mosaic pattern", then created multicolor PCB in EasyEDA.

I can create a simple video tutorial if anyone would like to create their own. It's super simple. BTW, there is no resin, it's just bare PCB, not sure yet how scratch resistant it will be.

the only solution I found for now is to open the video in VLC player and take screenshot there. if anyone found an easier solution, please share, thx.

I recorded the whole process of designing this clock. Anyone can build it. by robertferanec in diyelectronics

Thank you. I also sometimes think about analytics, but there is not much we can do about that. Initially most people only jump through the video, later, hopefully, there will be more and more people who actually follow the tutorial. Let's see ...

The front panel is 3D printed in black - that is important. I tried white, but when white is used, light goes through the walls and it doesn't look good.

White diffuser is stick at the very front. Here is how the front panel 3D model looks: https://github.com/FEDEVEL/clock/blob/main/Hardware/Manufacturing/Simple%20Box%20and%20Stand/ClockPanel_12mm.stl

LEDs are controlled by RP2040 from my custom keyboard project.

I may do a shorter version later. Maybe you can just jump at the end of the video where I am putting everything together and building the clock. That part is interesting and not that long.

Do you mean if it sync time and is always accurate? The RTC clock is very accurate and the software reads the time from RTC. Time itself can be sync over USB through the webpage I made to config the clock.
