I wanted my own compact keyboard. The reason is that the array of commercially available compact keyboards is strange, and there are also keys to press Fn key at the same time. I hated it. Also, since there is a mouse on the right side of the keyboard, I think that it is nonsense to arrange the arrow keys and the numeric keypad on the right. Furthermore, in Japan, a keyboard of Japanese layout is common. I confirmed almost all commercially available keyboards, but there was no keyboard that fulfilled these demands. Therefore I made the keyboard by myself.

This is original split keyboard version 3.

This adopts ISO placement. Use the Cherry MX mechanical switches. The controller disassembles and extracts the Microsoft keyboard wired 600. Fix the controller to ktKEYBOARD_BASE.

If you want to change part of this model, you can obtain and modify the following source code. (Coded in OpenSCAD) https://github.com/ktcode/ktKEYBOARD/releases/tag/ver.3
