University of Washington researchers 3D printed mechanical sensors and switches from standard plastic filament that can send data to Wi-Fi devices without using any electronics. As the engineers explain in this video, the plastic devices either reflect or absorb the ambient Wi-Fi signals and that effect is translated into a signal of zero or one. From the Printed Wi-Fi research page:
Specifically, we introduce the first computational designs that 1) send data to commercial RF receivers including Wi-Fi, enabling 3D printed wireless sensors and input widgets, and 2) embed data within objects using magnetic fields and decode the data using magnetometers on commodity smartphones. To demonstrate the potential of our techniques, we design the first fully 3D printed wireless sensors including a weight scale, flow sensor and anemometer that can transmit sensor data. Furthermore, we 3D print eyeglass frames, armbands as well as artistic models with embedded magnetic data. Finally, we present various 3D printed application prototypes including buttons, smart sliders and physical knobs that wirelessly control music volume and lights as well as smart bottles that can sense liquid flow and send data to nearby RF devices, without batteries or electronics.
4-Mation is a product being developed by Kevin Holmes, Jonathan Scoon, and Charlie Round-Turner that features a spinner that accommodates different 3D-printed animations, like the leaping frogs above. They also have this cute fish loop: They plan to offer three models, from basic to deluxe: 4-Mation is a modular 3D Zoetrope kit that will be […]
Retro Pi Cases makes and sells adorable housings for tiny computers, and their next model is going to be Tandy’s classic TRS-80. It’s not available yet, but checking out their site revealed to me their Commodore Amiga model, a no-brainer purchase.
Here's the eighth and final part of my reading (MP3) (party seven, part six, part five, part four, part three, part two, part one) of The Man Who Sold the Moon, my award-winning novella first published in 2015's Hieroglyph: Stories and Visions for a Better Future, edited by Ed Finn and Kathryn Cramer. It's my […]
