Let’s build a system able to detect the movement of people and objects through a video camera and send alarm e-mails with Raspberry Pi 3 B +. The so-called Computer Vision or artificial vision is a research sector that deals with how computers can interpret visual reality exactly like a human being; it uses…
A small integrated SMD gives life to an excellent portable FM stereo radio receiver which can be easily created because it does not require the production of coils or the calibration of tuned circuits. The semiconductor industry continuously churns out new integrated circuits for all application areas and also for consumers and audio; among…
Let’s experiment with the OpenCV 4 library in real-time face recognition and smile detection project. In the article “Home automation with OpenCV 4” we have introduced the OpenCV 4 library for Raspberry Pi, which represents a powerful tool to realize applications in the field of image detection with a specific camera for Raspberry Pi….
Let’s complete the description of the modular development system dedicated to connectivity and IoT, deepening the discussion of the dedicated framework. Second Episode. In the article published in the previous issue, we introduced the Mercury System, an innovative development system, particularly suitable for IoT and connectivity-oriented applications. At that time we focused on…
Modular development system that simplifies connectivity and IoT applications: based on boards that can be combined as LEGO bricks, on a complete software framework. Allows scalability and modularity. The Internet of Things (or IoT, whether you prefer), ie the capacity of certain objects, equipped with sensors, actuators and wireless interfaces, to connect to the…
A multifunction platform built around BBC’s micro:bit educational board. It integrates a cute robot, a starter kit and also a board for experimenting. Some time ago, in a previous article, we have reviewed the micro:bit controller designed by the BBC as an object aimed to develop logic skills and competencies in the field of computer…
We use the platform based on the AMS sensors in combination with the Personal Computer and thanks to an ad hoc software we trace on the screen the spectrum curves resulting from the analysis performed. In the analysis of materials, spectrometry has been used for a long time; this is a metrology technique based…
We present an automation solution that provides the ability to control a series of relays, using the local wired Ethernet network. All driven by the new version of the Arduino Yún board. The project that we present is born from the almost simultaneous availability of two devices that, although of different origins, lend…
Yes! The Raspberry Pi 4 is out with new features (and 4Gb of RAM). Here the info from official site by Eben Upton: We have a surprise for you today: Raspberry Pi 4 is now on sale, starting at $35. This is a comprehensive upgrade, touching almost every…
We are going to take advantage of one of the most known real-life examples in order to introduce the concept of blockchain, its characteristics and its practical usefulness, also explaining how to mine Bitcoins using an essential hardware platform such as Raspberry Pi. In today’s society, everything evolves really fast: lifestyle, communication… Even…
. It’s called Maker Art and it’s one of the main new features of the upcoming “Maker Faire Rome – The European Edition” scheduled to take place in the capital city from 18 to 20 October 2019. Maker Art is a project that aims to investigate the relationship between contemporary art and new technologies, through the creation…
Let’s take a closer look to battery chargers for electric cars provided by manufacturers. Those who have an electric car or at least a hybrid plug-in car (i.e. externally rechargeable) or whoever is in any way interested in the subject, will surely already know about them. They are also called Wall Boxes, EV Chargers,…
