Jesse Robinson created his own custom keyboard inspired by the Sun Type 6 keyboard.

Jesse wanted a keyboard that had the vast functions of the Sun and IBM keyboards and also had a number pad reversed to lay out like a telephone number pad.  The build process included fabricating a custom frame and hand wiring all 136 mechanical switches for the keys.

Getting the Teensy ++ to fit inside the slim case required using right angle header pins.

Additional photos of the build process can be found here.

Code as well case build files and wiring diagrams can be found on the Hackaday.io project page.
