Here we are, a great year full of innovations and open source project is passing by and we would like to celebrate with you this magic moment! As usual in this period, it’s time to take stocks of the work done so far, so here are the most visited posts on Open Electronics. Top 5…
(This is the second post of the OpenWheels series. See all the posts by clicking here) As you may know, the invention of the SegWay is due to Mr. Dean Kamen who, noting the difficulties faced by a man in a wheelchair in just climbing a sidewalk, spotted the possibility of a vehicle that…
Someone had already imagined, someone else hoped for that, days ago, finally one of the most prominent actors of the Makers ecosystem, Makerbot, announced a commercial desktop 3D Scanner. The good news, for those concerned with the openness of such a system, is that, well before that move, developers already created it: it…
We wanted to create a basic tool to experiment with the RN-42 Bluetooth module so we created obviously a Demoboard. The RN-42 Hardware module The RN-42 is a Bluetooth 2.1, Class 2 module with a PCB integrated antenna with a communication capability of about 3 Mbps. The version with the integrated antenna has…
IKEA’s Figgjo, is designed to be a mirror, but with a little ‘electronic can becomes fascinating light equipped wall clock. It’s a round mirror, from which twelve evenly spaced rays and this makes it perfect for a clock base. The twelve rays with small round mirrors will be our hours, while the circumference of…
Today we introduce you a robot fish that is able to swim and recognize tank edges and obstacles. We’ll find out how we can easily create it with common insulating material and a few servo motor controlled by Arduino.

The idea Ardusumo is a universal platform to build robots on wheels that can move around avoiding obstacles using infrared sensors and follow routes marked with dark lines on a white background. We have created Ardusumo to bring young students to the world of robotics: if suitably programmed, Ardusumo allows robots to perform various…
Let’s put together a pixel strip with an HL1606, an Arduino UNO and the Spectrum Shield to build a seven bands “large” Spectrum Analyzer of simple construction. [iframe_loader src=”http://www.youtube.com/embed/bVw02EXmmdo?hl=it&fs=1″ height=”349″ width=”425″ ] The components The Strip used uses the HL1606 controller to allow direct management of each of the LEDs. The chip runs two…
. [iframe_loader src=”http://www.youtube.com/embed/JMModx0y5g4?hl=it&fs=1″ height=”349″ width=”425″ ] This shield allows to connect an Arduino with DMX equipment. It implements the RS485 interface to adapt the electrical levels needed for DMX connection. This shield has been designed with flexibility in mind and allows the user to choose between several Arduino pins for digital input and output of…
In this post we present the design of a scale that connects to the Internet and automatically sends weight info on a Google Document. The project is composed of Arduino Uno board Wi-Fi shield additional shield that we used to manage data collection and I/O with a clear and comfortable and clear LCD display Velleman scale…
After a long wait, Arduino DUE is available for 39 Euro plus taxes: an aggressive price for ambitious makers. The key factor for Arduino success has been the ease of use and a very smooth learning curve. Thanks to its basic set of functionalities, a clear hardware design and the multiplatform Integrated Development Environment (IDE),…
There is a new project for halloween. This is a small modification to a lamp with tunnel effect commercialized by Velleman. There are different types and colors of this lamps, we chose this one because is very simple to find. The model that we modified uses 18 LEDs (red blue and green) and two fake…
