I love mechanical keyboards, and as a tinkerer the concept of making a custom one really appeals to me.

That said, the fact that the main page loads up dozens of multi-megabyte "thumbnail" icons is absolutely baffling.

This is really not out of the realm of a dedicated hobbyist.

The switches and keycaps can be ordered from quite a few vendors.

Also, custom circuitboards are no longer difficult to design or produce in small quantities (especially separate left/right boards).

Use a Teensy to wire it together as a USB HUD device.

3d print the case.

You mean USB HID, Human Interface Device.

Yes. Good catch.

Shameless plug for my own custom keyboard firmware project: https://github.com/dhowland/EasyAVR

Works with the Teensy

Thanks for linking this, I’m actually in the design phase of this project right now so the timing couldn’t be better. I’m going to try it some time this week.

So, I used to have a full-size keyboard with a built-in calculator as part of the numpad (had an LCD display above).

I would love to built an updated version.
