The night of the witches is coming: we need thus to gear up with a suitable decoration, so to create an atmosphere worthy of this celebration. For this circumstance there are many suggestions on the Internet, and specially creations made with 3D printers; among those available on the popular website Thingiverse, we chose a…
We will show here a modern take on the equipment that enabled time travel in Back to the Future. Those who have a few “decades” of ageing on their shoulders should know Back to the Future (but the younger ones as well, since they could know and see it thanks to YouTube streaming),…
The idea we propose in this article is dedicated to all those who need to set up a sound/speaker system in a residential or industrial environment: could be a natural park, a church, a mall or any place where you have to spread a spoken/musical message. The module that we propose, called Ethernet Broadcaster,…
It is open source and based upon the ATmega32U4 microcontroller, and provided with drivers for two DC brush motors and a stepper motor. It receives commands via USB or serial ports, or via the I²C bus. For those dealing with robotics, one of the problems to solve is the management of the motors used…
Take a picture, select a photo-effect and share it! Raspberry Pi 2 and RandA unite to create an interactive application we presented at San Mateo Maker Faire. At the past Maker Faire, held last May in San Mateo (California – USA), we premiered a project born to show visitors the potential of RandA…
Let’s couple the 3D gesture recognition electrode to Raspberry Pi, in order to create an application with which the pictures can be scrolled on a HDMI screen, by means of gestures. In the previous post we described a new GestIC electrode, which has been developed and created for the purpose of interfacing the…
With the board described here, we will interface the electrode board for gesture recognition to Arduino. To take advantage of the potential of the MGC3130 integrated circuit, we thought of developing a new electrode having the possibility to connect (in addition to our demo board, that we saw in the previous episode), even…
Why “Fishino” ? The names comes to a joke made on April Fools’ Day (in Italian “Pesce d’Aprile“, and ‘Pesce‘, which sounds ‘pashe’ means Fish) made on an Arduino forum where we “presented” a new board named “Fishino Zero” which had revolutionary technical specs. The symbol, placed on board’s picture with a graphical editor,…
Based on RandA, this machine can prepare cocktails, by drawing the quantities from dedicated dispensers, according to recipes dowloaded from the webpage from which the drink has been requested. Learn more in this first post. If one has the possibility to relax and maybe doesn’t have to get behind the wheel for a while, the…
This project presents a universal infrared remote control that can also be managed via Internet, based on RandA (supplied with a dedicated shield) and on Raspberry Pi2. Despite the fact that still only a few people take advantage of the “smart” revolution in home automation (intended as a complete and integrated automation and computerization…
Today we present the first steps with the NUCLEO development boards, produced by STMicroelectronics, that can help us to move towards the ARM 32-bit world with simplicity and great performances , keeping a compatibility with Arduino expansion connectors so that we can use its commonly available shields. The success of Arduino and its…
Let’s do some preliminary work with the board that bridges Arduino and Raspberry Pi: before getting into complex applications we’ll play by using cheap and available hardware components. RandA is a board that allows Arduino and Raspberry Pi to cooperate: it can be mounted on the latter and opens up a world…
