I’m not sure about Razer sorry. I only know Ducky and Keychron typically use switches with Cherry stems.

Others have mentioned Keychron and Ducky already but I just want to mention you can get the pudding keycaps separately for cheap off AliExpress.

A compact 65 for work, a slightly larger 75 for home along with a 40 to play games or experiment with.

Looks amazing. Will you release the gerbers?

Looks great, where are the key caps from?

Great colour scheme

Yes and no. For a cable with just different connectors, the kb or host would need to understand how to convert to the right protocol, PS2/XT/etc. The voltages are the same though I think (5V).

Something like this would be needed https://github.com/No0ne/ps2pico

I really like the wrist rest actually. What did you use for filling? Also did you need special needle and thread?

You might have seen this image (or similar):

The normal keyboard should have a flat PCB and the variation in height entirely based on the cap profile. Some profiles will have interchangeable keys, e.g. XDA you can swap the keys to any row except the first row while OEM you can’t really swap keys between rows or they’ll stick out.

As far as I know, you can use any profile on any board (provided the keycaps are compatible with the switch stems).

Hopefully that helps answer your question.
