Keebin’ With Kristina: The One With The Folding Keyboard Mod

Let’s face it, failed Kickstarters are no good. But they can spark good things, like real versions of technologies that might have actually been faked for the platform. A touchscreen mouse, for instance, with shortcuts that can be programmed for various applications.

This story is one of scope creep, as [Sam Baker] says in the project details. At first, he thought he could just basically duct tape a touchscreen with shortcuts to an existing mouse. A couple of mouse teardowns later, [Sam] arrived at the conclusion that things would not be so simple.

After some digging around, [Sam] found a repository where someone created a way to communicate with the ADNS-5050 optical sensor, so [Sam] started by creating a breakout board for this sensor. By combining that with an ESP32 dev board and a touchscreen, [Sam] had his shortcut mouse.

Does it work? Yes. Is it useful? Well, yes. And also no. The beauty part of using a regular mouse is that you don’t have to look down at it to know where the buttons are. In the future, [Sam] would like to implement some kind of buttons for tactility. In the meantime, haptic feedback could be nice.

Spherical Keyboard Build Leaves Hacker Well-Rounded

May 20, 2021 by Kristina Panos 20 Comments

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.
