Here we are, eventually the contest has come to an end and after a short consultation we have chosen the winners! Before announcing them, a few words. First of all, thanks to everyone who submitted his contribution. All the works reviewed are great and must be praised, because they represent without exception a hard work,…
An area of application of Computer Vision, one that has always fascinated people, concerns the capability of robots and computers in general to determine, recognize and interact with human counterparts. In this article we will take advantage of the availability of cheap tools for computing and image acquisition, like Raspberry Pi and his dedicated video…

Well, when it comes to creating original chocolate mixes you will probably be born, but if you want to succeed in the art of pastry, then everyone can be made: you just need…
Let’s see how to use the Camera Pi module, a quality photo video camera, purposely designed for Raspberry PI, to acquire the first knowledge concerning Computer Vision, to recognize colors and shapes. Camera Pi is an excellent add-on for Raspberry Pi, to take pictures and record quality videos, with the possibility to apply a considerable…
We’ll show you today how, with just a few modifications, we can apply the GSM/GPS shield management library to the Arduino compliant TiDiGino open source remote control, so you can manage optimally the capabilities of the SIM900 mounted on it to implement cellular connectivity. As you may know already, TiDiGino is the development and prototyping…
Robots provided with autonomous operation capabilities and, particularly, those sporting sense organs similar to the human ones, have always tickled the fancy of science fiction writers and screenwriters. As always happens, from a certain point in history, even official science has started to deal with the subject, at first with the so-called “strong theses”, whose…
Today we’ll explain how to exploit the potential of Arduino as a programmable logic controller, connecting it to appropriate interfaces for I/O. The PLC (Programmable Logic Controller) has been and still is the basic component of the industrial automation world. The Industrial application made the PLC systems being very expensive, both to buy and repair,…
[youtube id=”0721A1kZ3s0″ width=”620″ height=”360″] Here we present a tool to measure and acquire data. It is open source, and made by using the Xilinx Zynq 7010 Soc. It was funded with KickStarter and it is suited to be customized and adapted to various application exigencies. The idea, which required funds for 50.000$ for its…
[youtube id=”eINAuYg-ftM” width=”620″ height=”360″] This robot will mow the grass of your garden, staying within a defined area, avoiding all obstacles and working in complete autonomy, automatically charging itself with a solar panel. In this post we present a robotic lawn mower, powered with solar energy and able to operate just with the clean energy…
Since when white light emitting high brightness LED are available, the handover from traditional lighting bulbs to the solid-state lighting has become irreversible: LEDs have an efficiency (expressed in lumens/watt) higher than that of almost all the traditional lamps (except, at the moment, the large sodium vapor lamps used for street lighting, unusable in closed…
Use Arduino as a Xively HTTP client and interact with the new shield for power management. We already talked about WiFi connectivity for Arduino in other posts, presenting the design of a high performance WiFi shield and explaining how to use it both as a web server, or a web client. The two modes of…
Since long past times, when Gugliemo Marconi has amazed the entire World broadcasting his radio signals from the Elettra ship, a subject held dear by electronic engineers has been radio transmission. After these years, the scenario has changed a lot, firstly with the appering of digital technologies (DAB, for instance) and, up to day,…
