In less than two weeks the Maker Faire will come to Rome. It’s a 3-day gathering of makers, hackers, companies and hobbyists with the passion for electronics, programming, manufacturing, artistry, learning and creating. There will be some practical workshops, tons of lectures, and bigger talks called “cortocircuiti” (shortcircuits). It will be hosted in the University of La […]

The online “university” coursera.org organizes its courses with limited time frame, to give the students a sense of urgency to complete the studies. These courses, which are relevant to the content of my blog, are about to start: VLSI CAD: Logic to Layout; start date: 2013-03-04 Pattern-Oriented Software Architectures for Concurrent and Networked Software; start date: 2013-03-04 Information Security […]

Makeblock: the body of your open hardware projects.

December 23, 2012

I have always been the LEGO kid. I especially liked the space sets, but I understood quite soon that the Technic series was the best for me. A couple of times in my life, when I wanted solutions to small physical problems such as “how can I fit this webcam to the top of monitor?”, […]

A thesis on Arduino

April 18, 2011

I’m reading an interesting university thesis on Arduino, from Fabio Varesano’s blog, that I follow: My MoS Thesis: Using Arduino for Tangible Human Computer Interaction | Varesano.net. This thesis is a useful resource especially for people with a Computer Science background; it can generate many project ideas and arm any hobbyist with the tools to […]

Capturing an analog signal with Arduino and python

March 26, 2011

Last week I salvaged a magnetic sensor from a stationary bike and connected it to my Arduino Uno in order to analyze the sensor’s behavior with the ADC converters.   I wanted to capture a good enough signal, so I searched about the Arduino capabilities: From analogRead() reference description: It takes about 100 microseconds (0.0001 […]

Salvaging an old stationary bike RPM sensor

March 20, 2011

I had to dispose of an old stationary bike that little by little fell apart. Before throwing it away I wanted to see if I could salvage something from its simple electronics. The bike has a sensor that somehow detects the rotation of the crankset and then is used to display the RPM on a […]

ZPUino open source processor

March 6, 2011

0

ZPUino is a project that offers a microprocessor that can be put on FPGA, and that can be programmed with a simple IDE. Everything is open source: the toolchain, the IDE and the VHDL code; and it can be downloaded freely. The hardware architecture is based on the ZPU (Zylin CPU), which is a processor […]

Getting started with Arduino Uno on Ubuntu

January 31, 2011

I really wanted to try Arduino; Arduino narrates a story where the good guys are winning. Saturday I arranged to buy one, the Arduino Uno, and the first thing that came into my mind was “Wow, it’s really smaller than I thought possible!”. I went home and started unboxing it: the packages comes with a […]

Taking a look at Arduino schematics

January 23, 2011

Out of curiosity I wanted to check some Arduino board schematics. The Arduino Uno is one of the newest boards and is also quite simple; its open source schematics can be downloaded from here(zip file). There are two files: a board layout file and a schematics file. They can be opened with the free (but […]
