Astronomers solve 900-year-old cosmic mystery surrounding Chinese supernova of 1181AD

“A 900-year-old cosmic mystery surrounding the origins of a famous supernova first spotted over China in 1181AD has finally been solved, according to an international team of astronomers. New research published today (September 15, 2021) says that a faint, fast …

Beaming broadband across the Congo River

“Taara’s wireless optical communications links are now beaming light-speed connectivity from Brazzaville to Kinshasa across the Congo River What if we could bring fiber-like speeds to unconnected and underserved communities that, because of the geography or cost, fiber can …

Project  clOCkTAL

clOCkTAL

“Because binary coded decimal clocks are too easy to read. Binary Coded Octal clock with auto brightness control, based on a PIC16F688, developed with SDCC. Firmware The heart of this minimalist clock is the zero error Bresenham algorithm. It uses …

Creating a RISC-V system with an FPGA

“In this project you will learn how to implement a RISC-V processor in a SmartFusion2 SoC. Everybody knows that the processor of the moment is the RISC-V, even it is not a processor itself, the amount of the …

Dumb but Great Point and Shoot Camera with ESP32 CAM

“A completely portable ESP32 Based Point and Shoot Camera setup that works, kinda works. So the idea here was to take this very useful ESP32 CAM board and flash it with a sketch that lets us take an image and …

Engineering various sources of loss provides new features for perfect light absorption

“Natural and manmade physical structures all lose energy, and scientists work hard to eliminate that loss or compensate for it. Optical and photonic devices lose energy through light scattering, radiation or material absorption. In some situations, however, intentionally yet carefully …

Engineers create 3D-printed objects that sense how a user is interacting with them

“Advance incorporates sensing directly into an object’s material, with applications for assistive technology and “intelligent” furniture. MIT researchers have developed a new method to 3D print mechanisms that detect how force is being applied to an object. The structures …

ESP32 and Toit: Log sensor data to Google Sheet and emailing

“An ESP32 board will read pres and temp from BMP280 sensor and log the readings to Google Sheets. Furthermore, we’ll also send email alerts. The majority of IoT applications revolve around the use of sensors to automate practically anything …

Ethical Artificial Intelligence is Focus of New Robotics Program

“Ethics will be at the forefront of robotics education thanks to a new University of Texas at Austin program that will train tomorrow’s technologists to understand the positive — and potentially negative — implications of their creations. Today, much robotic technology …

Groundbreaking Technique Yields Important New Details on Silicon, Subatomic Particles and Possible ‘Fifth Force’

“Using a groundbreaking new technique at the National Institute of Standards and Technology (NIST), an international collaboration led by NIST researchers has revealed previously unrecognized properties of technologically crucial silicon crystals and uncovered new information about an important subatomic particle …
