Among the user interfaces available on the market, there is the one recently developed by Microchip and based on a new technology for gesture recognition, suitable for the creation of innovative man-machine interfaces. This function is created by means of a dedicated integrated circuit, named MGC3130, capable of detecting a basic series of movements, and…
More and more often we find the opportunity to create Internet-connected projects by ourselves, in that category known as the Internet of Things (IoT), within which you can find smart appliances, home automation systems, medical devices, security systems and many others: a complex world, sharing the ability of being connected to the Internet. The…
We add to Raspberry Pi a TFT touch screen to display the system console, movies and favorite photos or control a relay board … at your fingertips, literally! To avoid using an HDMI monitor the cost well above that of Raspberry Pi, in previous articles we have always gone the way of connecting remotely to the…
We are going to build an internet-connected, Arduino-based display, on which we could write directly from a smartphone, by sending the messages over WiFi. In the late 90s of last century LED displays have begun to replace or complement the classic Signs on cinemas and business activities in general. Those displays could be…
The Internet of Things is slowly becoming real: let’s discover a long-range wireless technology that is particularly suitable to create simple and cheap wireless networks, that are able to connect billions of intelligent items among them. Depending on the estimates, by 2020 the number of Internet-connected devices will be between 20 and…
Microsoft Kinect for Xbox revealed itself as an excellent scanner, with which to acquire the shape of items. Let’s see how to use it along with ReconstructMe, that in its more recent versions allows the creation of models that are accurate and ready to use. The scan of solid objects, better known as 3D…
[youtube id=”XpYjn9-xgvY” width=”620″ height=”360″] We have already seen many motorized versions of “human traction” transport means: bicycles and scooters, for example, or even some skateboard, but surely we lacked the motorized skateboard controlled by a smartphone. Well, now we have found it! It is a dedicated project, which combines the motorized version of the popular…
In case you missed our previous articles, we summarize briefly what is RandA. RandA is a system that allows a physical and functional integration between Raspberry Pi and Arduino, allowing the use of Arduino shields with the Raspberry Pi computational power. It also includes an intelligent power management and a RT clock. In figure shows RandA…
In the previous posts we presented the project of an an embedded MP3, capable of playing and recording audio sequences by means of appropriate commands. The interaction modes, as well as the communication interfaces cover a wide range of possibilities, for example it is possible to easily use UART, USB, I²C or bit banging on…
The operation principle of this circuit is very simple and easy to describe. The basic idea consists in supplying a device that is capable of operating since it is first started: this is why we created a software, in order to automatically generate a preset configuration file, with default values, that can be modified at…
Today we present the heater capable of keeping two syringes loaded with chocolate always ready for using with the 3Drag. A couple of months ago we tried to surprise you by showing another astonishing transformations of our printer 3Drag: the ability to print objects and decorations with chocolate. Well, if you decided to buy the…
It is time to use the board that combines the capabilities of Raspberry Pi to Arduino ease of use. Raspberry Pi and Arduino worlds got close but they did not collide: indeed, they have resulted in a cooperation that has created a hybrid of enormous potential. We started talking about it in this post, where…
