I need to try making one too. With an Arduino that has usb C port instead.

But first i need to learn pcb design and order one. I have soldering and programming skills.

A 3d printer would be nice but I don't have one.... I do have some woodworking practice and my dad can help me here as well for a case.

You should try it. It's not that hard.

I didn't know how to design a PCB too. My soldering skills is really bad, you can see it in the picture. But learn enough to make a macropad is not really difficult.

Simple little beautiful piece. Any recommendation for start with pcb design? I have soldering and programming skills but never felt comfortable in pcb design or anything electrical related :/

Nice job, did you 3d printed the keycaps ?

I used KiCad for designing the PCB.

To start, you should learn the basic first. Youtube have a lot of that kind of video:

  • Schematic: Add Symbols, Labels, Wiring, Named Symbol reference, Assign Footprint (Remember to select the right footprint)
  • Board: Layers, Fill zone, Wiring.

Then you should learn how a keyboard works:

  • Learn how Microcontroller sends a key to computer
  • Keyboard matrix, how Microcontroller knows which key is pressed.
  • Make sure that your Microcontroller has enough pins for the matrix.
  • Learn how to use Diode

After that you can get back to KiCad and make a keyboard PCB. At this time, the hardest part is wiring, you will learn when you do it.

Good job! it’s useful for copy pasting stuff from stack overflow.

For what it's worth, once you have the circuit designed the circuit layout software can often route all of the tracks for you within parameters that you define (eg. Key placement, track and pad dimensions, minimising wire bonds to bridge over tracks etc...)

Nice! What do you use it for? Are those knobs used for volume control?

One of the knobs for volume control, the other is for page up/down. At first is for Brightness control, but I don't use it often. 3 of the keys for Slack's shortcuts, because I work with Slack alot. 1 for locking OS (Ctrl + L). 1 for open terminal. 1 for open terminal in a folder.

ai03 has a great set of articles explaining the 101 of making a keyboard pcb amn using KiCad. I started designing my own PCB a couple weeks ago and it was very helpful.

Understanding or knowning what components to use and why they have the value they have is the challenging part for me. Sometimes it's detailed in the documentation of the integrated circuit, but sometimes you just have to look for what others on internet did.

For only macropad's components, it cost about 16$ (I have to pay for some redundant circuits). But of course, there are some tools for soldering, shipping fee, etc.

2 for jump forward/backwards to unread channel. 1 for jump to threads - the menu in sidebar that lists all of the threads that I'm in, order by the new message first. Useful to jump into new thread's reply.

I found an useful macro for reaction a favorite emoji to a message. But I don't have enough keys now.

Agree, That's hardly from scratch. However, I think "from scratch" has different levels. We can't build a Microcontroller from scratch, right?

And it only cost 20$ including shipping fee :)

  • ProMicro clone: 4$
  • 2x Knobs: 3.36$
  • 6x keycaps: 2.18$
  • 2x rotary encoders: 1.26$
  • 1x plier: 0.8$
  • 6x switch: 1.6$
  • solder: 0.8$
  • 10x PCB: 5.46$

= around 20$ (shipping fee is included, some of them are free shipping)

And 4$ for a Soldering Iron.

That looks really nice and I'd love to try to build my own. That said, I don't have any experience with custom PCBs so not sure how I go from your source files to a physical PCB. Any chance you could document how to do that?

Good resources! Thanks for sharing. I'm also making my first macropad, but already ordered the PCBs.. anyways the tips from those articles will be useful for the next one.

I like it. Very much. Should rework mine a bit, but I struggled with the values coming off the rotary encoders. How did you solve this if I might ask ?

Go for RP2040 based MCUs, everything else is extremely outdated by now.

Edit: for example KB2040, Helios, Frood RP2040, at least here in the EU. Don’t really have examples beyond the KB2040 for US. If you Design from scratch, of course your don’t have to use the pro micro footprint

Dude, nice. I have a similar project in limbo myself, I just need to learn to design the PCB and get it ordered. The breadboard prototype is working and gathering dust on my desk though. So, congrats on actually completing the project.

Looks really cool man, I was going to buy one of these but building one looks much more fun. Do you think this would be doable for someone with no experience? I studied software engineering about 10 years ago so know the basics on the coding side.

Maybe someone in here can answer:

Is it possible to get a machined aluminum casing for it? Like, I send someone a CAD file and they mill it or manufacture it in the most appropriate way? Who offers such a service?

There are files in the pcb/plots folder. They called Gerber files. You can compress those files and send to a PCB manufacturer.

If you want to custom, then just edit the KiCad project, then generate new Gerber files.

This is probably prohibitively expensive. That's why even the keyboard manufacturers have interest checks and group buys. Even then companies like Keycult are struggling to deliver on the quality promise.
