My keyboard building history
So you want to build your ultimate keyboard but know nothing about electronics, soldering or any keyboard design concepts. No problem. That's exactly how I felt back in 2018. And still, after 2-3 months I typed on a keyboard designed and manufactured by myself. Here is my story to inspire you.
There are several ways to build a keyboard. The gradual handwiring approach described below is only one from many. However, while not the easiest path, I know this approach actually works and is quite effective.
You can buy a kit or assemble a keyboard from parts but starting with handwiring really helped me to understand all the aspects of keyboard building.
A few months before I heard of mechanical keyboards for the first time, as a lucky coincidence, I came across Arduino.
Without any background in electronics I bought a cheap starting kit and tried my luck with sensors, motors and development boards of the Arduino family. (2018/04).
Logical layout design & layers
That summer, still completely unaware of mechanical keyboards, I tried to intuitively optimize the Hungarian QWERTZ layout on my classic rubberdome with swapping some character pairs (JN, ED, TF).
I used softwares like AutoHotKey, PKL, TouchCursor (SpaceFN concept) etc. to achieve these modifications and try my hands an an additional layer with a non-programmable rubberdome.
I've build various corpora from books and wrote my own scripts to calculate language statistics, generate, evaluate and compare layouts.
After playing with this project for a few weeks, and by the time I heard about mechanical keyboards for the first time, I knew exactly what the design faults of the classic physical layout were and how QWERTY (QWERTZ in my case) should be improved.
When I stumbled upon mechanical keyboards in late summer of 2018 I started to contemplate on how an ideal keyboard would look like: columnar staggering, ditching of the numpad and arrow cluster, thumb clusters, split/angled design etc.
Lurking & learning
One way of getting familiar with my options was a daily visit to the r/mk sub (August 29th, 2018). I tried to ignore overhyped stuff and focus on ideas and innovations. (There were 200k subscribers at the time and the sub was more building oriented. Nowadays, r/ErgoMechKeyboards is a better alternative.)
When I came across a term I didn't understand, I looked it up and tried to read everything about:
- switch types
- split keyboard layouts
- handwiring (build logs are great!)
- and manufacturing
I took collecting links about split boards to the next level by compiling a searchable database of split keyboards. Literally hundreds of them.
At the beginning I had to look up even the most basic terms like voltage, diode, capacitors, anode-cathode etc. One of the most useful sites full with tutorials was Sparkfun (check their early articles about basic electronics).
Arduino has taught me to search for components, to use datasheets, pinouts, and I had to solder for the first time.
Where to order parts
Because of the shipping costs your location pretty much defines the shops of your choice. I went for cheap components and ordered almost everything from kbdfans, kprepublic and other sellers from aliexpress with free shipping.
I was quite sure what I wanted but still started with an easy build. I didn't want to spend a lot of money on a hobby I'm not sure I'll like. So my first project was a $5 cardboard macropad (2018-11).
It's an ideal project to learn and test everything from soldering to programming before building a proper keyboard.
Another good technique was cardboard prototyping. With free materials (shoe boxes) laying around I tested layouts and even created working keyboards.
At the beginning I used KLE and the plate builder. However, these are not ideal for splits. Thus, after I knew the proper dimensions (e.g. cutout size) I continued designing my plates in Inkscape.
Thanks to my cardboard prototypes I was pretty sure even a few millimeters count when it comes to staggering. That's why I didn't buy an Iris kit but went straight with designing and building my own layout.
Typing on your own keyboard
After building the macropad I designed and built my ultimate keyboard and was typing on it by Christmas of that year.
Even if this was a really cheap prototype ($40) with cardboard plate, it turned out to be surprisingly usable and I typed on it at home for almost a year. I have to say, typing on your own creation is a great feeling.
Btw, the Corne plate drawings were my starting point. Since I've learned everything from free resources, I published my keyboard plate designs too.
Looking for local shops/businesses
I wanted to try acrylic and steel plates. As a first step I checked online services, but their prices were unreasonably high.
Handwiring & Build logs
The most valuable sources of information were possibly build logs. Any build log has the potential to teach you something new.
Also, I tried to document and publish my building process to help beginners.
I spent a lot of time with browsing the QMK documentation. However, once I was settled with my layout, I flash the same firmware on new keyboards.
On the quest for the ultimate switch/caps
Looking for the best switch/caps can be a long and expensive journey. Here is my keycap history.
I'm settled with Kailh Box whites and a Big Bang MDA set. Yeah, I like light, subtle clickies and a relatively low, sculpted profile with homing bumps.
Nowadays I still build keyboards occasionally, mostly for myself, with slight modifications of my very first design.
