Osprey Keyboard Lets The NRF52840 Spread Its Wings

While most people don’t care whether they use one finger or ten, some people want to better themselves by learning how to touch-type. And honestly, there’s no easier way to do that than by getting into the ergo keyboard game. Even if you consider yourself a touch-typist already, an ortholinear or column-staggered keyboard may teach you otherwise, as you find yourself trying to type ‘c’ with your index finger (for example) and failing miserably.

[ebastler] chose the best of all routes and decided to build his own perfect keyboard, called the Osprey. It’s a wireless, column-staggered 40% that runs on ZMK firmware, which of course is open-source, as is the PCB itself and the thick and travel-ready printed enclosure. Although [ebastler] has yet to implement either one of these additional inputs, the Osprey also supports a thumbstick and a track pad.

Brain-wise, it’s a bare nRF52840 chip along with a TI BQ24075 for battery charging. The interesting thing about this implementation is that [ebastler] used and abused Nordic sample schematic #4, which utilizes both DC-DC converter stages of the chip. We can’t wait to see what this trailblazing build will mean for the community!

Toast Keyboard Raises A Glass To Short Index Fingers

Custom keyboards? They’re totally great. And we can keep telling you this, but you really won’t feel it until you try a few and find one or two that are right for you. If you’re already on board, we wonder: is there any limit to what custom keyboards can provide in terms of a good, comfortable time for your fingers, wrists, arms, shoulders, and neck? We think not, and as time goes on, there is more and more evidence to support this.

Take [vpzed]’s Toast keyboard for example. The beauty of customization is that as with any other human input problem, you’ll discover many more people who share your misery once you present a solution. In this case, it is the portion of the population whose index fingers are shorter than their ring fingers (which is evidently men in general). This is known as the 2D:4D ratio and is decided during gestation. At first, the phenomenon was thought to be due to high testosterone exposure in the womb, but subsequent studies have debunked this belief.

Toast aims to sate the need for a keyboard layout that accounts for a significantly shorter 2D than 4D by way of aggressively staggering the index finger’s key positions and staggering the columns overall. As you might imagine, there are no inner keys for length-challenged index fingers to grasp at — that would just be cruel. But there is another pinky column on each hand, which bring the key total to 34. We like the square boards, and frankly wish they were bread-shaped.

Not enough keys for you? Take a look at this many-keyed monoblock split with a numpad in the middle.
