A geeky Christmas decoration made with 56 LED Neopixel and controlled via an Arduino Micro board: Let’s take a look, therefore, at the project’s electrical section, that is essentially composed of a set of 56 Neopixel LEDs, that have been arranged so to form two concentric stars;...

In this video tutorial educ8s.tv shows us how to load bitmap graphics in our Arduino Touch Screen projects using Adafruit's GFX library. The procedure that I am going to describe works with all the color displays that are supported by Adafruit’s GFX library and by the displays that...

by Susan Nordyk @ edn.com: A wide input range of 4.5 V to 40 V enables the TS3004x series of DC/DC synchronous buck regulators from Semtech to work in a wide range of applications, including industrial, telecommunication, and consumer. The current-mode TS30041 and TS30042 furnish 1...

by Jan Buiting @ elektormagazine.com: In a stint of list-o-mania TE Connectivity have slapped five environmental sensors on a single board called MEAS for plugging onto the Arduino/Genuino 101 and Uno R3. Here goes in telegram style. MEAS: five weather sensors on one Arduino shield...

Sergey Kiselev designed and built an Intel Quark D2000 micrcontroller based Environmental sensors board: This is a fairly small (51 x 51 mm) board, equipped with a low power Intel Quark D2000 microcontroller, and several sensors (accelerator, temperature, humidity, atmospheric...

Researchers at the University of Central Florida have been looking for alternatives for lithium rechargeable batteries which are largely used in every device. Using two-dimensional (2D) transition-metal dichalcogenides (TMDs) capacitive materials, they are building a new supercapacitor...

The Bluetooth Special Interest Group (SIG) has officially launched the core specifications of the new version of Bluetooth: Bluetooth 5. These specifications include longer range, faster speed, and larger broadcast message capacity, as well as improved interoperability and coexistence...

Robert Gawron has been working on a semiconductor radioactivity detector project: Currently I’m trying to make a working version of a radioactivity detector that uses semiconductor as a sensor. It’s a different approach than Geiger-Muller detectors, more complicated, but also...
