-description: Process of how to create a custom designed hardwired keyboard
-created: 2024-03-01

-
-TODO ROUGH PRICE
-
-## Plan
-Start out by getting a rough plan of what you want to make, so you can order parts, as takes a while, if you wish to do 
-it cheaply.
-
-First of all you need to decide how big your keyboard needs to be, do you wish to make an 100%, macropad, ultra-compact, 
-split, do you want dedicated buttons for all 24 function keys? none of the above?
-
-You can play around with [keyboard-layout-editor.com](http://www.keyboard-layout-editor.com/) to find a layout you like,
-see different layout under "Preset"
-
-Massive repo of inspiration: [keebfolio.netlify.app](https://keebfolio.netlify.app/)
-
-### Switches
-#### Design (Will affect keyboard design)
-- Cherry MX design (classic, old, bulky, readily available, cloned into oblivion)
-- Low profile?
-  - Kalih Choc (Expensive, different keycaps)
-  - Others
-    - [gateron.co - Gateron Low Profile 2.0 Mechanical Switch](https://www.gateron.co/products/gateron-low-profile-mechanical-switch-set)
-    - [keychron.com - Keychron Low Profile Mechanical Switch](https://www.keychron.com/products/keychron-low-profile-mechanical-switch)
-Unsure, order a Switch tester or ask a friend to try their switches, to see what you like
-#### Type
-Generally there 3 types, originally made by cherry, I'd recommend none of them
-- Clicky - Typically blue (obnoxious)
-- Linear - Typically red (Did I press that button?)
-- Tactile - Typically brown (Mushy)
-
-But do limit your scope enough, so you don't lose interest before completing the core project.
-Be ready to test ideas feasibility and scrap them if infeasible.
-
-### Switch matrix
-So what parts do you need?
-You need to decide which method you wish to use, to wire up your switches
-- Matrix with diodes (recommended method)
-  - Requires 1 diodes per switch, diodes are cheap
-  - Cable routing is more manageable
-- Straight (1 wire per switch to microcontroller)
-  - Requires enough pins
-
-An I/O expander can be used to add additional pins to a microcontroller, it's also useful for split keyboards, 
-as it can require only 4 pins (I²C + power and ground) from the microcontroller
-
-## Order parts (Consumables)
-### Checklist
-#### Keyboard specific
-- Switches
-- Microcontroller, look at [QMK Compatible microcontrollers](https://docs.qmk.fm/#/compatible_microcontrollers),
-i recommend a RP2040 based microcontroller
-- Keycaps? Do you want to order these or [3D print them](#3d-printed-keycaps)
-- Diodes [aliexpress.com - 1N4148](https://www.aliexpress.com/item/1005005435418695.html)
-- Split keyboard parts
-  - I/O expander route
-    - I/O expander MCP23017
-  - Connector [aliexpress.com - TRRS headphone jack](https://www.aliexpress.com/item/1005003146932723.html)
-  - Cable [aliexpress.com - TRRS headphone cable](https://www.aliexpress.com/item/1005001781279058.html)
-
-#### General maker
-- 3D printed filament
-- Solder tin
-- Extra features?
-Get wild, add an old [ThinkPad trackpoint](https://docs.qmk.fm/#/feature_ps2_mouse), 
-a [rollerball mouse](https://shop.pimoroni.com/products/trackball-breakout?variant=27672765038675), 
-rotary encoder, maybe LEDs.
-- Heat shrink tube
-- Magnet wire (can come in handy)
-
-### Tools - non consumables
-- 3D printer
-- Soldering iron
-- Continuity tester (for debugging connections)
--

-## Waiting for parts
-### Layout design finalisation
-Staggered?
-Ortholinear?
-Something else entirely?
