Preface

This repository contains all the source files needed to create a 87 key (tenkeyless) mechanical keyboard.
In order to actually build this keep in mind you'll need access to the following.

  • PCB fabrication.
  • CNC, laser or waterjet cutting.
  • Soldering iron and supplies.
  • A source for your switches, stabilizers and electronic components.

Licensing

Software in this project is licensed under the GPL. See GPL.md
Hardware in this project is licensed under the TAPR. See TAPR.md

Details

  • Tenkeyless layout.
  • Compatible with Cherry MX switches and both Cherry and Costar stabilizers.
  • LED support for each key.
  • Does not require a resistor for each LED.
  • N-Key roll-over, no ghosting, 1 diode per switch.
  • Firmware which allows for custom key mapping, macros, de-bouncing and LED control.
  • Mini-B connector.
  • Teensy 2.0++ controller. Some images of a completed prototype based on the designs in this repo are in the "prototype_images" folder. PlatePCB

Project Files

  • /dashkey/* - Firmware for the keyboard, codenamed DashKey. Coded by SiberX.
  • /fabrication/* - Final project files to be sent off and fabricated.
  • /kicad_files/* - Kicad project. Open the file "openclack-tkl.pro".
  • /notes/* - Notes explaining the LED configuration, parts list, info on the boost converter, resistors.
  • openclack.skp - Rough 3D render of the project (SketchUp).

Instructions

There's currently no guide on how to do this but if you're technically inclined it should be doable with all the files contained herein. If someone wants to develop a guide feel free to contribute!

Sources/Thanks

Thanks to the folks at http://deskthority.net/ for helping out when I had questions about measurements!
Also a big thanks to BathroomEpiphanies. Wouldn't have been able to do it without your amazing wiki. Check it out here!

Questions

How big is the Openclack tkl PCB?

It measures 345.7 × 134.1 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Openclack tkl use?

206 parts, built around the MC34063ABN. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Openclack tkl KiCad files?

From the jtryon/openclack repository on GitHub, at the commit this page was made from: the board is kicad_files/openclack-tkl.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Openclack tkl design in my own project?

Its repository states no licence, so its author keeps all rights: ask jtryon before reusing the design.
