Silent deep bass: Wearable audio you can feel
Researchers at University of Tsukuba have developed a portable, silent subwoofer that combines electrical muscle stimulation with low-frequency vibrations. This device enables users to physically feel deep bass in virtual reality (VR) and everyday music. While minimizing noise, it provides an immersive experience and rhythm perception comparable to conventional speakers, opening new possibilities for audio experiences.

I love that these legacy adaptor projects exist, even if I don't have a personal need for them.

Open-source hardware USB to GPIB adapter connects legacy GPIB/IEEE-488 instruments to modern hosts
XyphroLabs's UsbGpib is an open-source hardware, inexpensive, and portable USB to GPIB adapter aiming to provide "access to legacy GPIB/IEEE-488 instruments using contemporary hardware and software, with a focus on accessibility, openness, and ease of integration into current workflows". Initially developed by Hewlett-Packard in the late 1960s/early 1970s, GPIB (General Purpose Interface Bus), also known as IEEE-488 or initially HP-IB (Hewlett-Packard Interface Bus), is a short-range digital co…

Abstract: The discovery of optical frequency combs (OFCs) has revolutionised science and technology by bridging electronics and photonics, driving major advances in precision measurements, atomic clocks, spectroscopy, telecommunications, and astronomy. However, current OFC systems still require further development to enable broader adoption in fields such as communication, aerospace, defence, and healthcare. There is a growing need for compact, portable OFCs that deliver high output power, robust self-referencing, and application-specific spectral coverage. On the conceptual side, progress toward such systems is hindered by an incomplete understanding of the fundamental principles governing OFC generation in emerging devices and materials, as well as evolving insights into the interplay between soliton and mode-locking effects. This roadmap presents the vision of a diverse group of academic and industry researchers and educators from Europe, along with their collaborators, on the current status and future directions of OFC science. It highlights a multidisciplinary approach that integrates novel physics, engineering innovation, and advanced researcher training. Topics include advances in soliton science as it relates to OFCs, the extension of OFC spectra into the visible and mid-infrared ranges, metrology applications and noise performance of integrated OFC sources, new fibre-based OFC modules, OFC lasers and OFC applications in astronomy.

A proud achievement of my half-century IT career happened in 1996 consulting to the #UNDP toward the first published edition of the Humanity Development Library.
It seemed easy enough: "It can be fairly estimated that 1/3, or about 20 million pages of UN, and as much University and NGO material are very useful. Those 20 million pages useful UN publications probably contain about 50% of solutions for major World problems. This information must be released in digital format for non-profit redistribution in all countries."
also portable and accessible to all platforms, everywhere.
Happily, not only did the project live on, but thanks to @… our once-intractable problem of global delivery is now globally solved!
So, whether or not this is timely, I don't know, but should you need to suddenly rebuild some semblance of civilization from scratch…

Been looking at portfolios and CVs and Websites for people who applied for a "Creative Technologist" position.
And it's kinda disheartening to see that almost all pages and projects look very much the same.
The way that "we just focus on one dominant technology/narrative and visual language" limits people's development and horizon is depressing.

Portable printer developed for fabrication of origami devices
In the present times, origami-inspired three-dimensional (3D) devices are being developed, where a single sheet of material is folded into small devices. These devices are being developed for medical applications like stents or surgical tools; agricultural devices like soil-sensors; and efficient spacecraft radiators or solar arrays that are used in space technology. Along with innovation, it is also important to focus on sustainable technology that can fulfill human needs and is adaptable to e…
