Supercon Talk: Sophy Wong is Designing the Future of Wearable Technology
https://hackaday.com/2019/11/27/supercon-talk-sophy-wong-is-designing-the-future-of-wearable-technology/
For many of us, the term “wearable technology” conjures up mental images of the Borg from Star Trek: harsh mechanical shapes and exposed wiring grafted haphazardly onto a human form that’s left with a range of motion just north of the pre-oilcan Tin Man. It’s simply a projection of …read more (https://hackaday.com/2019/11/27/supercon-talk-sophy-wong-is-designing-the-future-of-wearable-technology/)

Bringing The NES Cartridge Into The USB Age
https://hackaday.com/2019/11/27/bringing-the-nes-cartridge-into-the-usb-age/
An NES cartridge in its most basic form is a surprisingly simple device, it contains two ROMs hosting all the code and assets of its game, and a Nintendo code chip that provided what was a state-of-the-art consumer DRM system for the 1980s. Decades later its inner workings have been …read more (https://hackaday.com/2019/11/27/bringing-the-nes-cartridge-into-the-usb-age/)

A Single-Digit-Micrometer Thickness Wood Speaker
https://hackaday.com/2019/11/27/a-single-digit-micrometer-thickness-wood-speaker/
Researchers have created an audio speaker using ultra-thin wood film. The new material demonstrates high tensile strength and increased Young’s modulus, as well as acoustic properties contributing to higher resonance frequency and greater displacement amplitude compared to a commercial polypropylene diaphragm in an audio speaker.

Hacking Transmitters, 1920s Style

The origin of the term “breadboard” comes from an amusing past when wooden bread boards were swiped from kitchens and used as a canvas for radio hobbyists to roll homemade capacitors, inductors, and switches. At a period when commercial electronic components were limited, anything within reach was fair game.
