Clawtype version 2.1 is a compact, one-handed input device combining a chorded keyboard and mouse. Using only five keys, it allows for typing, mouse movement, clicking, scrolling, and modifiers like shift and control. The device connects via USB and its small size makes it portable and suitable for use in confined spaces. The creator demonstrates its functionality in a video, showcasing text entry and mouse control, highlighting its potential for efficient one-handed computing.
Ken Shirriff created a USB interface for a replica of the iconic "keyset" used in Douglas Engelbart's 1968 "Mother of All Demos." This keyset, originally designed for chordal input, now sends USB keystrokes corresponding to the original chord combinations. Shirriff's project involved reverse-engineering the keyset's wiring, designing a custom circuit board to read the key combinations, and programming an ATmega32U4 microcontroller to translate the chords into USB HID keyboard signals. This allows the replica keyset, originally built by Bill Degnan, to be used with modern computers, preserving a piece of computing history.
Commenters on Hacker News largely expressed fascination with the project, connecting it to a shared nostalgia for early computing and the "Mother of All Demos." Several praised the creator's dedication and the ingenuity of using a Teensy microcontroller to emulate the historical keyset. Some discussed the technical aspects, including the challenges of replicating the original chord keyboard's behavior and the choice of using a USB interface. A few commenters reminisced about their own experiences with similar historical hardware, highlighting the significance of preserving and interacting with these pieces of computing history. There was also some discussion about the possibility of using this interface with modern emulators or virtual machines.
This blog post details the creation of "Bayleaf," a custom-built, low-profile, wireless split keyboard. The author prioritized a slim design, opting for Choc low-profile switches and a custom PCB to minimize thickness. They used Kailh Choc Red switches and keycaps from MBK. The keyboard halves communicate wirelessly using the nice!nano microcontroller and connect to a computer via Bluetooth. The build process involved designing the PCB, 3D printing a case, and flashing the firmware. The result is a compact and portable split keyboard tailored to the author's preferences for ergonomics and aesthetics.
Hacker News users generally expressed interest in the Bayleaf keyboard, praising its low profile and split design. Several commenters compared it favorably to other low-profile keyboards like the Keychron K1 and K3, highlighting the Bayleaf's even thinner form factor. Some questioned the key travel and overall feel, expressing a desire for more details on those aspects. Others discussed the challenges of designing and manufacturing such a slim keyboard, particularly regarding keycap compatibility and battery life. A few users also showed interest in alternative layouts and the possibility of open-sourcing the design. Several comments focused on the keyboard's aesthetics, with some finding it appealing while others considered it too plain.
Cosmos Keyboard is a project aiming to create a personalized keyboard based on a 3D scan of the user's hands. The scan data is used to generate a unique key layout and keycap profiles perfectly tailored to the user's hand shape and size. The goal is to improve typing ergonomics, comfort, and potentially speed by optimizing key positions and angles for individual hand physiology. The project is currently in the prototype phase and utilizes readily available 3D scanning and printing technology to achieve this customization.
Hacker News users discussed the Cosmos keyboard with cautious optimism. Several expressed interest in the customizability and ergonomic potential, particularly for those with injuries or unique hand shapes. Concerns were raised about the reliance on a phone's camera for scanning accuracy and the lack of key travel/tactile feedback. Some questioned the practicality of the projected keyboard for touch typing and the potential distraction of constantly looking at one's hands. The high price point was also a significant deterrent for many, with some suggesting a lower-cost, less advanced version could be more appealing. A few commenters drew comparisons to other projected keyboards and input methods, highlighting the limitations of similar past projects. Overall, the concept intrigued many, but skepticism remained regarding the execution and real-world usability.
