Fake Kishsaver 3d Printed Mechanical Keyboard

A mechanical keyboard case imitating the appearance of an IBM Kishsaver keyboard. Features a 5 degree typing angle and tofu68 style layout.

This model requires you to print tall for the case - make sure your Z-steps are calibrated correctly. No support material is required. Assembling this keyboard is mildly frustrating.

Required hardware

• 8x 10mm M3 bolt and nut
• USB-C breakout board and some kind of adhesive e.g. CA glue
• EC11 rotary encoder
• atmega 32u4 breakout e.g. Teensy2.0
• the usual handwire stuff - diodes etc…

When assembling and disassembling, you will need to keep the case inverted so that the hex nuts stay in their holes.

QMK firmware

• sick68 firmware ported to Vial with rotary encoder support - https://github.com/xia0/vial-qmk/releases/tag/v1.0

Handwiring

• Wire as you would a normal sick68. Rotary encoder A and B are on pins F1 and F0.
• Snippets from firmware below:

#define MATRIX_ROW_PINS \
    { D3, D2, D1, D0, D4 }
#define MATRIX_COL_PINS \
    { C6, D7, E6, B4, B5, B0, D5, B6, B2, B3, B1, F7, F6, F5, F4 }

#define ENCODERS_PAD_A { F0 }
#define ENCODERS_PAD_B { F1 }
