It's available again.

Yes. Service stopped shortly before noon. DNS resolves fine, but the server itself is currently not up it seems.

Alternatively, instead of trying to have a microcontroller or processor system that is fast enough to do as described in the above paragraph, a electronic matrix using electronic switches can be built. But this obviously requires more hardware. This is what spectratur does, using an Arduino Nano (o...

For a decent keyboard I use Cherry Keys. I know such a thing exists somewhere for PCs as well. They are just very rare compared to the PC Keyboards I know.
