Really, really nicely done. I was expecting that the thumb clusters just had the one hinge so that as you increase the tent they'd get further away but this is super cool to see!

Would love to see the PCB version of this if you make it. The wire wrangling seems rough, especially for my skills 😅

The wiring is pretty tedious. I have a version 2 using a PCB in the works...

This is a very great and I nteresting project. I am also surprised to see the predecessor project brrfly-keyboard, because this is exactly like my dactyl monoblock based on the python code .

Maybe I should do the next step as well….

Oh wow, that is a very cool design, particularly the thumb cluster tenting/folding. Seems to get most of the dactyl manuform thumb ergonomics without a super bulky keyboard.

Would be great to know how this is to type on. Is it pretty stiff or is there flex in the joints and material?

That was one of the main goals!

Its quite stiff, the prints are thick and the "legs" that fold out friction fit into the baseplate to keep everything rigid. It feels as stiff as my btrfly.

Is it stable when you are typing fast? What about the noise?

btw, very impressive work

SolidusHalOP•

Completely stable, the supports connecting the keyswitch plates are angled, and friction fit into the baseplate to make the whole thing very rigid when deployed.

thanks!

Awesome. How is the tented thumb cluster with choc switches?

SolidusHalOP•

It works well, I can do the same rocking motion I do on my brtfly with MX switches

Really fantastic design! How long did it take to print?

5
SolidusHalOP•

I think roughly 10 hours to print all of the parts

The fact that I could put this in my laptop case and have an tented keyboard wherever I go is awesome

SolidusHalOP•

It fits nicely in the zipper pocket on the outside of my laptop case

Brilliant! Is it parametric? I need my num rows.

5
SolidusHalOP•

Unfortunately, no. Adding a num row would be a pretty intensive process.

You have my attention

YES MATE. This is fantastic.

I want to do something very similar in the fighting game controller space. How sturdy is this? Do you play games? If so, I'd kill for some close-up footage of the keyboard as you mash some keys.

this is a fabulous idea and I plan on making this when I get back from vacation, I love the mechanism and utility of being able to fold the keyboard up and take it on the go and then have the comfort of the tenting once you get to the location of work. I wonder when they will offer pointing device support in zmk so the trackball can be wireless.

I have plans to add something like that in the future

New life goal unlocked: design an ultra-compact tented keyboard that opens up like one of those pop-up books.

As in, it folds in the middle to close, and opening/closing it automatically tents/untents it.

henrebotha•

Oh my god. Yes. And it would be its own dust cover whenever it's not in use.
