A sandbox for ergonomic keyboard makers.

Dactyl Chimera Leaves The Learning Out Of The Curve

Have you been wanting to build your own keyboard, ergonomic or otherwise, but are hesitant to spend all that time and filament on something that may not be a good fit for your hands? Glad as we are that the dactyl is open-source, to get in there and really mess around with it requires intimate knowledge of either OpenSCAD or Clojure.

Well, not anymore. [WolfIcefang]’s dactyl chimera is an ergo sandbox, a test bench for column curvature, stagger, and height that should keep you from having to iterate all day and night. It was designed in FreeCAD and has three parts — the rack, the tenting foot, and the arches. The rack acts like a bottom plate and has slots for holding the columns (arches) in place. Underneath that is the tenting foot, which changes the lateral inclination. Thirdly are the arches, the business part where the switches go.

[WolfIcefang] says it’s sturdy but not portable, and for some reason feels the need to apologize for the looks. We think it’s beautiful, but then again are easily captivated by such practicality. It’s not quite a keyboard yet, as [WolfIcefang] has neither wired it up nor burned in any firmware. This is still in the early stages, and [WolfIcefang] wants to open it up to collaborators. Plans for the future include interchangeable thumb clusters and a complete build guide.

Even if you aren’t that fluent in OpenSCAD, you’ll have fun messing around on the keycap modeling playground.

Spherical Keyboard Build Leaves Hacker Well-Rounded

Often times we as hackers don’t know what we’re doing, and we sally forth and do it anyway. Here at Hackaday, we think that’s one of the best ways to go about a new project, and the absolute fastest way to learn a whole lot as you go. Just ask [Aaron Rasmussen] regarding this spherical, standing 5×6 dactyl manuform keyboard build, which you can see in a three-part short video series embedded after the break.

[Aaron] gets right down to it in the first video. He had to get creative right away, slicing up the dactyl manuform model to fit on a tiny print bed. However, there’s plenty of room inside the sphere for all that wiring and a pair of Elite-C microcontrollers running QMK. Be sure to turn on the sound to hear the accompanying voice-overs.

The second video answers our burning question: how exactly does one angle grind a slippery sphere without sacrificing sheen or shine? We love the solution, which involves swaddling the thing in duct tape and foam.

You may be wondering how [Aaron] is gonna use any kind of mouse while standing there at the pedestal keyboard. While there is space for a mouse to balance on top, this question is answered in the third video, where [Aaron] learns the truth behind the iconic ThinkPad nubbin and applies this knowledge to build a force-feedback joystick/trackpoint mouse. Awesome answer, [Aaron]!

Not ready to go full-tilt, sci-fi prop ergo? Dip your toe in the DIY waters with a handy macropad.

Inputs Of Interest: Curves Are The Key To My Type

While I may have fallen in love aesthetically with the ErgoDox I built, beauty is only skin deep. And that’s funny, because you can see right through it. But the thing is, it’s just too big and knife-edged to be my daily driver. I keep missing the space bar and thumb-thumping the acrylic wasteland between the thumb cluster and the mainland.

The point was to make a nice portable keeb, even though all my trips for he foreseeable future are going to be limited to the bed or the couch. But it has to be comfortable, and the ErgoDox in its present state simply is not long-term comfortable. I’d take it over a rectangle any day, but it would probably end up being a half day.

Ergo isn’t so much a preference for me as it is a necessity at this point. I feel like I can honestly say that I might not be typing these words to you now if it weren’t for the Kinesis. I don’t want my fingers to do unnecessary legwork, or downgrade from the quality of typing life that concave keys have afforded me. So let me just say that using the ErgoDox made me want to build a dactyl even more than before.
