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.
Here's part four of my reading (MP3) (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 Burning Man/maker/first days of a better nation story and was a […]

Lithophanes were originally bas-relief artworks made of translucent porcelain that let varying amounts of light through depending on thickness. Now they same effect can be created using a 3D printer and applied to anything from Wonder Woman images to personal photos.
Python is one of the most popular and versatile programming languages used by developers today, making it an ideal first choice for those looking to kickstart a career in programming. While you could go back to school or sign up for a pricey coding bootcamp, you can learn the essentials of coding with Python at […]
Going back to school isn’t necessarily an option for everyone. Between the time commitments and steep tuition rates, there are obstacles aplenty as far as furthering education is concerned. However, that’s not to say it’s impossible to learn new skills. Excel with Business lets users access thousands of hours of online learning in Microsoft, business, technology, […]
More often than not, you won’t see an accident coming, which means it pays to be proactive and ensure you have the right tools on-hand before you need them. Whether you find yourself in the middle of a power outage or having car trouble at night, you can make sure you’re still capable of navigating […]
