Help me make a "MechaMatrix" 2030 #keyboard, please?
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?
Just looking at the TypeMatrix for the first time. Looks like a pretty interesting layout. Manufacturing a mechanical TM(TypeMatrix) clone is likely going to be pretty difficult, but becomes more possible the more you diverge from the design.
At a high level though, the main issues I see at first glance is that TM is using laptop switches, custom legends, and 1/2 size function row keys.
The only analogue to laptop switches in the mechanical keyboard world is Kalih X switches, but they're hard to come by and a bit more difficult to design for, but they just might work with the TM keycaps, but don't quote me on that.
Choc switches are possible, but you're not going to get legends (the letters and symbols on the keycaps) unless you have them custom made, which is next to impossible if using traditional methods. Same story with full size MX switches. You might be able to fill out the alpha-numerics, but the secondary legends in blue aren't going to be there, not to mention the vertical shift, back space, enter, and control.
As for the 1/2 size function row, you'll have to compromise and go with full 1u keys because there aren't any switches out there that will fit in a 0.5u size, not to mention lack of keycaps. And speaking of odd-sized keycaps, you might run into issues with Choc keycaps for the spacebar in particular, as I don't think anyone manufactures a 5u spacebar in choc form factor, and the 2u shift, enter, and control keys will need choc stabilizers, which are pretty hard to find IIRC.
So, with that all said, these are the compromises you're probably going to have to make to get a completed keyboard:
- MX (tall) switches, maybe-possibly choc depending on stabilizer availability and design compromise for spacebar
- Legendless modifier keys and no secondary legends on alpha-numerics
- Likely a flat keycap profile (a.k.a no OEM, SA, or Cherry profile keycaps)
- 1u function row instead of 0.5u
There's a few routes you can go down to get his done.
-
Pay someone else to do it.
-
Learn how to do it yourself.
If you take route 1, it's going to be much more costly than route 2 most likely, but far less time and effort invested to get a working product. I'm sure there are plenty of people who have designed their own PCB/Keyboard that would be willing to design yours for the right price.
If you take route 2 then you're going to be putting a lot of time into learning different software packages, how a keyboard works at the circuit level, and how to solder at the very least; but you'll have done all the work yourself, which is pretty gratifying IMO.
A good place to start learning is "ergogen". It's like a configuration language and accompanying software for designing keyboards programmatically. It's not especially complicated and has plenty of resources on YouTube and in written form. There are online viewers that make it easy to visualize the layout you're configuring, and other projects on Github that can take ergogen output files and convert those to pcb design files that are ready to send off to manufacturing, 3d printed case files, and and interactive BOM (bill of materials) that can help you when it comes time to solder the switches, controller, diodes, etc.
First thigs first: Thank you for your help.
Don’t care much about the labels. What you see on the picture is the BÉPO keymap, (A Dvorak for the French language) which is how my keyboard is mapped. But what is printed on my actual keyboard is AZERTY, which is what most French peoples use instead of QWERTY.
No problem, glad to help point you in a useful direction. If you're not especially concerned with labels, you might be able to get around needing to have a blank set of keycaps laser etched or something like that.
I also got bored yesterday and had your idea of a TypeMatrix 2030 kicking around my head, so I decided to mock-up a layout similar to what I described in the previous post, and created a Github project you can use as a jumping off point if you want to proceed that direction.
https://github.com/pyunramura/mechamatrix2030
Keep in mind, the layout probably needs some more thought and the pcb generation part of it has not even been started, but it should be possible to get a completed board with some learning, some funds, and some work.
One of the major issues I didn't think of before is the fact that the keyboard has quite a lot of keys, so many in fact that the matrix is too large for a standard pro-micro type microcontroller. The keyboard has 7 rows and 15 columns which needs 22 pins, which is unfortunately 4 too many for a pro-micro. There are other microcontrollers with a similar footprint that might be suitable instead though. Elite-C, Blackpill, and some of the RP2040 boards come to mind.
I am willing to help, but in what capacity?
I have previously built a janky atreus clone, and designed and built a non janky numpad. Both with QMK.
- What help do you need?
- What is your budget for the project?
Thanks for your willingness to help.
I'm not that good in electonic, so I might need help on the plans on that front, along with what resistors or diods I need. (I do know how to solder &, at worst, know someone who can help on that part IRL.)
For the design part, I have found somone else's project I can use as a base, and have switches and some keycaps I might be able tu re-use, but might very well need help with QMK and what micro-controler to use.
I once had two typematrix 2030s. Both were dead within a couple years, may have even got a warranty replacement on one(which would mean three died within two years), but I don't recall for certain. I truly hate that they don't have a more durable and/or premium version available.
Mine have more than 10years. I was very lucky.
I used to have two Type Matrix boards long time ago. It got me into thinking about more ergonomic layouts and taught me first Dvorak and later Colemak. I agree with others' comments about poor longevity. I also find that it's not a very ergonomic layout in hindsight.
Learning how to clone this layout in a custom mechanical keyboard is like jumping into the deep end. There may be other ways. E.g. get an XD75 or ID75 and make a layout that's "close enough". That takes PCB design and lots of firmware hacking out of the equation. But you'd still learn about different switches, layers, thumb keys, maybe home-row-mods if you want and ease you into more possibilities of firmware hacking. You may find a more ergonomic or efficient layout than the Type Matrix that way, as well.
As far as options for replicating the layout go, I think ErgoArrows would be the closest - you can get it as a kit.
If it's more about the middle keys than the a bunch extra keys on the bottom, there are many keyboards like that - Ergodox/derivatives, Kinesis Advantage360, Moonlander, Redox, Dygma Defy, and Keyboardio Model 100 all have 2-3 keys in the middle and can be bought pre-built. ErgoDash, Ergo68, and Pinky4 can be bought as a kit.
Oddly enough, I have the same neglected side project for the same reasons! I'm at work at the moment but will post what I have so far later. I'll also walk through my aporoach to be noob friendly and cost effective.
Thanks, apreciated.
