Hello to all keyboard enthusiast here on the Fédiverse.

For the longest time, I have used a TypeMatrix 2030 as my daily driver, most of which was spent daydreaming of finding a close approximation that would be mechanical. Failing to find one, I procrastinated in researching how I could build my own, which was an error.

Now, my good old TypeMatrix is showing signs of dying, and I still don’t have even started on its mechanical replacement. So, I would like help and counsel on how to make one.

I don’t need it to be identical, (I don’t need the rightmost column on the actual TypeMatrix, for example) but I DO need the middle column with “del”, “backspace” and “enter” keys.

Would anyone be willing to help me, please?

    Since you’re in EU you have quite a few options for vendors. Here is a good list.
    I looked through most of these vendors before and it’s unlikely that you’ll find everything you need to build a fully custom keyboard from a single vendor, but with 2 or more you should be able to source all the pieces you need.
    Some vendors that have a decent selection:

    Another option of you don’t mind the potentially long shipping time is to buy all the components from Aliexpress. They will likely have an expansive selection and lower price compared with EU retailers, but you may or may not end up paying tax, and the shipping time will be longer on everything.

    I managed to figure out an ugly way of getting the keyboard matrix down to 20 pins, but a much better option to using a pro-micro would be to go with an Elite-Pi or Helios Microcontroller Since it has 23 GPIO pins, and there won’t be a hacky workaround like with the pro-micro.

    One thing I forgot to mention is key switch preference, the two main types are MX (high profile) and Choc (low profile). MX switches are both easier to find and have much larger variety of both switches and keycaps. Choc is nice because it has a lower profile similar to laptop keyboards, but the selection of switches and keycaps are much more limited. There are other low profile switch types like Choc mini (PG1232), Choc V2(PG1353), and Notebook X(PG1425) switches, but they’re even harder to source than the Choc V1(PG1350).
