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.
Charged with paying a 16-year-old girl for sex at a hotel in Austin, Texas, Cody Wilson was bailed Sunday and is a free man again—at least for now. The BBC reports that Wilson, famous for promoting 3D-printed gun plans, was arrested by Taipei police and returned to the US over the weekend. KHOU 11 filmed […]
Hydrophytes are 3D-printed multimaterial forms that explore the possibilities for engineered plants of the future.
The Smarter Bridge is a project led by Mix3d, which makes robotic 3D printers that can sinter stainless steel structures and inch their way along the surfaces as they are completed.
Speed reading isn’t just an innate skill possessed by a lucky few. Anyone can learn to speed read, and the benefits are endless. The brain can process more information than most people have time to soak up, but you can make that time now with the 2018 Award-Winning Speed Reading Bundle. The first half of […]
Sure, you could use the same old PowerPoint templates for your next business presentation. It’s not like you have bosses or investors to impress. Oh wait, you do? Time to augment that slideshow with Slideshop – the presentation tool that can individualize your pitch while saving you time. Compatible with PowerPoint, Keynote and Google Slides, […]
Multinational companies have used the no-nonsense methodologies of Six Sigma and Lean Six Sigma to oil a smooth-running operation for years. What is it? Six Sigma (and its offshoot, Lean Six Sigma) apply the principles of science to business, teaching managers to methodically target waste, maximize output and streamline the flow from producer to consumer.
