A friend of mine was working on a Osu! keyboard lately. It's small. It shines. Case made of aluminium and PVC. Cherry MX switches inside. Powered by 5v Adafruit Trinket. No CNC, all done by hand.
Anyone knows anything smaller?

That's a sophisticated switch tester. Anything smaller?

Now you just need a 1 and 0 keycap

Does that keypad also fix osu timing? Cause I'm not touching that game again unless it does, I'm too afraid to lose my MA.

is it NKRO?

Sure thing and it just works wherever you connect it

Nice!
Can you give more details on the electronic part of this project?

not keen myself... prefer a vertical layout to a horizontal

Wouldn't the smallest be one key? It could be used for Morse code

It wouldn't neccessarily be smaller, as Trinket microcontroller's size forces the case to be this "wide".

Sure thing. As soon as that friend gets home

Update:
Two switches are wired to separate I/O pins and to GROUND. LEDs are connected to 5v and to GROUND with 220 Ohm resistors.

* Custom made PCB or a arduino/AVR/PIC-development board?
* Own firmware or something like the tmk firmware?
* Where are the separate layers of the "case" connected together? Glue? Screws? Some special "snap in" mechanism?
* Are the keys configured to send a fixed key (like UP and DOWN) or is this configured over serial or something?

*Adafruit Trinket 5v
*Basically this:https://learn.adafruit.com/trinket-usb-keyboard/code with the code just a little modified.
*Snap in would be cool and fancy, but it's just some Superglue not enough space for screws. Thing is tight.
*It's preset by the code. Now it works as "Z" and "X", but can be reprogrammed. However, no additional drivers or programs are needed for this to just work.

I don't know that you'd call it a "keyboard" per se, but TechKeys.us offers a One Key Keyboard.
