## Why I've decided to make my own keyboard
|
||||
|
||||
I've been feeling pain in a wrist of my right hand for 2 years now. I've started to feel it when I started to be more physically active. I've been working out and played a lot of squash. It got to the point that I had to visit an orthopedist. I was scared that I'd have the infamous **carpal tunnel syndrome**. At this stage he said it was just strained. The pain eased out after some therapy but it still comes back and it got to the point that I had to change my work habits.

One night I was checking out the state of programming streams on _twitch_. I've found a great streamer [JMS WRN](https://www.twitch.tv/jmswrnr) and as I was chatting with him about my wrist problem he gave me a recommendation for my new mouse: [Logitech MX Vertical](https://www.logitech.com/en-us/product/mx-vertical-ergonomic-mouse?crid=7) and then he showed me that he has a _Discord channel_ just for keyboard stuff. And that was **the moment** for me. I've discovered a whole new world of possibilities around keyboards.
|
||||
|
||||
I've started to do a research around custom keyboards, their parts, _QMK software_ and its possibilities. I was 100% sure that, if I am going to make my own keyboard it would be **split and ergonomic**. It just looks so cool to be able to have one part of the keyboard away from the other.

But then I've found the shipping cost and that changed my decision. I was looking into other options that were accessible in Europe and then I've found [FalbaTech](https://falba.tech/), who is based in Poland which made me so excited.

I took a look at his selection of custom keyboards and decided on the **Redox keyboard**. It is a split orthodox keyboard heavily inspired by **Ergodox**. There are two options for this keyboard: Classic wired and wireless. I've decided for a wired one as I didn't want to complicate my first build.

You might think that making a custom mechanical keyboard can be cheap but the opposite is quite true. The electronics are the cheapest part and they are not that hard to get. You might find many of them in the nearest radio amateur shop. Parts that you have to reconsider and are most important are the PCB, case, switches and keycaps.

## Assembly time

So I waited a few weeks for the goods to arrive home and after everything that was needed for the assembly came I've scheduled the assembly to be done over the weekend. First weekend had came by and I was not feeling it, so I moved it to the next one when I was sure I wouldn't be interrupted by anyone. It fit very well because I was soldering the keyboard over the night that was on a day of parliamentary elections. I knew that I was going to be up very late anyway.

### 2. Solder switching diodes

What's nice about keyboard assembly is that, when you are going to solder for the first time or like me the second time after 12 years, it starts from the simplest tasks to the hardest. In the end it is simple all the way because after first 70 soldered joints you will get into it and you will learn how the solder behaves.

PCBs of Redox are the same for both sides. That means you will put diodes on the opposite side of the PCB that it is going to be used for second hand.

Remember that the **direction of the diodes matters** and that means the black part of the diode should be placed at the square on the PCB!!!

When you are done with soldering be careful while cutting the pins. They are going to fly across whole room. Also you should wear protective glasses if you are not able to point them to be shooting away from you. I was able to find some pins after 2 weeks in the corners of the room.

At this point, you would notice that the USB port is going to be very low and not very tight on the left side. Please be aware of this. If you want to, you can also just wire some leftover pins from the diodes and make them shorter but I was doing OK with the head pins of the Pro Micro.

Try to put at least few switches on the case and try mounting them on the board. The PCB has holes in it to mount the switches so it should fit together. Mine didn't so I had to make a little hack on a few switches so they wouldn't bend my board by cutting their bottoms.

To be honest, I had to revisit and try to fix both of my Pro Micros. One full column of my keyboard was not working because of one bad contact. I was trying to unmount whole Pro Micro out but wasn't able to suck the solder out so I desperately just tried it out again and it worked. I just needed to apply more heat to it. Few days later, my Enter key was not working and it was the same problem, but on the other side.

The USB ports on the Pro Micro are infamous to break when you manipulate a lot with them. I've decided that I want to have my right hand side as a master and the USB port broke after 3 days. I was not able to burn a new firmware on it but I had to rewire the RGB backlight and I use my left hand side as a master. On the left hand side the USB port is sitting between the board and Pro Micro so it should be harder to break. Be careful with them anyway!

Well, I just made a big change in my experience with writing. I was learning to write with 10 fingers and if that wasn't the biggest change I've made. I've decided that if I am going to learn to write properly I'll do it even better. I've learned to use the **Colemak keyboard layout**. To enhance it to the best experience possible I've built myself an **orthodox split keyboard** and I must say: **_WORTH IT!_**

So what are the little things that come with switching to orthodox keyboard, you may ask. Well it depends on your habits. Mine were certainly very bad as I didn't know how to write with 10 fingers. Only 8 in my case. Also I was used to type H and Y keys with my left hand. But that was not the biggest problem. Most errors I've made was by trying to hit `C` key. I was used to hitting it with my pointer finger which I think is not only my issue. With the classic keyboard design, hitting the `C` key with middle finger seems like a torture. After one month I am now able to properly hit any key with the correct finger. I just still do many mistakes because of the layout change.

I've chosen very light switches because I wanted them to be less noisy as I work in a shared office and also my ol' _Cherry browns_ seem a little too hard to me. I have to say this change was very hard to get used to. First 3 days I was accidentally pushing `oooooooooooo` key while trying to concentrate on which key I should press while learning new shortcuts. Simply put, I cannot rest my fingers on keyboard like I've used to. But I think that they are not that bad after I got used to them. Sometimes I accidentally press `Backspace` just before hitting `Enter`. Therefore I'd definitely recommend getting heavier switches for function keys. If I was to make another keyboard, which I am definitely going to make, I will choose something in between. When I try to type on my old keyboard I feel like I have to do push ups with my fingers. But I know it is just because I got used to these light ones.
