Prism Mechanical Keyboard

Prism is a low cost QMK compatable 60% + nav cluster (or TKL minus F-row if you prefer) keyboard.

It came about for a number of reasons:

• I had some TGW71 PCBs designed by u/ca178858 lying around doing nothing
• I am procrastinating instead of doing my PhD thesis writeup
• There was a competition on r/CustomKeyboards to build retro themed keyboards.

As it was planned for the OG Summer competition I decided to emulate some of the design language of the ZX Sepctrum family of computers (particularly the the ones that came after the 48k).

Initial Design document

To Do

• Improve feet fastening/height adjustment
• Update .dxf to include latest revision

Future Plans

Currently this repo is a bit of a dumping ground for what I have designed so far, though it is possible to recreate the keyboard entirely. Eventually I want it to include:

• Multiple plate layer configurations
• Multiple top layer configuations
• Changes to the PCB to include PCB mount stabilisers and better bottom row support

Current status

Prototype complete - Displayed at Mechanical Keyboard Meetup (Leeds 26/10/2019)
