lagrange-keyboard VS keyboards

You can see an example in the photos of my Lagrange keyboard.

I was looking for a suitable example for a tutorial for my programmatic solid modeling CAD Gamma and a clamp seemed suitable. Well, I haven't started work on the tutorial yet, but here's a clamp-mount assembly for my Lagrange keyboard.

I had both my Expert Mouse and the Orb I'm now using, between the two halves of my Ergodox and now my Lagrange. Ergonomically, it is, I think, the natural choice, but perhaps the separation between the halves is larger than average in my setup.

As for Gamma: I wasn't really aware of CadQuery, but I did use OpenSCAD extensively, when designing my Lagrange keyboard. Gamma started as a way to address some aspects I didn't find quite satisfactory (as, to be fair, I can't say I had any real problems). Also to be fair, I used OpenSCAD through a frontend(scad-clj) translating Clojure code to its native language and some of the problems may have been due to that, but that is also one of the issues I had with OpenSCAD: why have to learn a new language when there are existing embedabble scripting languages, you might now already, of if not, which you might use elsewhere and which, having years of development, will likely be better?

This is not about the Dactyl per se, but my Lagrange keyboard supports this (or at least attempts to; it's hard to guarantee that the resulting geometry will be problem-free for a given set of parameters). The build guide goes into some detail on what you're trying to do.

I've tried it. In fact, I've designed it, I designed it as a key meant to be operated with the edge of the palm with my Lagrange keyboard. This doesn't mean it couldn't be used as a thumb key of course, but note that you could also create your own custom version of this (or other keys).

I started with an ErgoDash [1], purchased because my Microsoft/Logitech split keyboards had worn out, and at the time I couldn't find a replacement with normal (not low profile) keys. It has a few additional keys compared to the Iris. I have one at work and another at home, and to make them more similar to the broken keyboards I 3D printed angled bases. I use it for 99% of my typing.

I should probably have tried a Kinesis Advantage 2 first.

I'm partway through printing/assembling a Lagrange keyboard [2] (I'm currently stuck working out how to order the circuit boards), which is similar to the Dactyl. I will add the F1-F12 keys to my print, as they're the only thing I miss -- if a shortcut in my IDE is Ctrl+Shift+F10, it's nice for it to be that, not Ctrl+Shift+Fn+0.

I made [3] to help others see what's available.

I don't use a DM, but if the question is whether something like the DM could be used as a daily driver, or whether something "less radical" would be preferable, I can say that I've been using my Lagrange as a daily driver for more than a year now. Its geometry is comparable to that of the DM and, from what I can tell, it's more aggressively curved.

I was warned by a colleague that this was a rabbit hole, then warned by people online, and I'll pass on that warning now.

I tried to help by updating and better-presenting an existing list of ergonomic mechanical keyboards: https://aposymbiont.github.io/split-keyboards/

I'm using an ErgoDash¹ with a 3D-printed tilted stand, but I intend to assemble a Lagrange² "soon".

Having spent quite a bit of time over the past couple of years designing a concave keyboard (the Lagrange) and therefore having a sort of vested interest, psychologically speaking, to say "yes, definitely!", I would say: depends what you mean by "worth it".

You can see an example of this with the Djinn Rev 2a

I have found one with no wireless module (djinn) but i really want a wireless one.

Blood, sweat and ⠀tears were shed, but I think it was worth it. Big thanks to u/tzarc for the great piece of kit and for all folks on the djinn discord channel for putting up with all my noob questions! All the required info is here: https://github.com/tzarc/djinn Now I just have to learn to type better 😂 Here are some progress pics https://imgur.com/a/5h1qPb1

There may be enthusiast mechanical keyboards that use faster ports. My keyboard uses an Elite-C MCU in each half. I've heard some more modern stuff is switching to ARM for the MCUs.

Here's a keyboard that uses an ARM MCU:

Most of the open source designs do not have protection on the TRRS connector. There are many kinds of protection that can be built such as for ESD (static electricity), over voltage, over current (short circuit), noise (interference), etc. All of these require components and board real estate. You can check out the Djinn Djinn keyboard It implements protection on the TRRS port and it is a BEAST. The Pro Micro form factor for MCU boards is pretty small so there is limited space for this kind of circuitry. However, if a keyboard has an onboard controller (no separate microcontroller) it might have some protection, at least on the USB connector.

You can. I learned from this guy: https://github.com/tzarc/djinn. I just don’t remember how (I haven’t used kicad in a while). You might be able to figure it out by looking at the footprints he used here. Even the MCU footprint is a reversible one with all the traces included iirc.
