Update : See the end for source and HEX files.
The &#8216;MIDI Piano Instructor&#8217; is a tool aimed at improving the piano keyboard self-teaching experience with direct interaction between the student and software (or human, remote) teacher.
The new level of interaction is reached when the student is guided on the notes to play or exercise on <a href='http://www.5volt.eu/archives/94'>[...]</a>]]></description>

I remember writing as a kid in the mid &#8217;70s to an electronics magazine well-known in Italy, Nuova Elettronica, asking them to publish the project of a device to display music on a TV like on an oscilloscope. They did not reply but eventually they published the project. I&#8217;m not sure I&#8217;m the one who <a href='http://www.5volt.eu/archives/85'>[...]</a>]]></description>

I was 6 years old when man reached the moon. I barely remind those days : sure they must have been very exciting for those in the age of reason. Today I&#8217;m looking back at that accomplishment as the result of spirit of adventure, bravery, stupidity, lack of common sense, careful betting and something more, <a href='http://www.5volt.eu/archives/84'>[...]</a>]]></description>

Most modern energy meter have one or more LEDs which blink at a rate directly related to the energy used. The one above has two of them : one pulses at 1000 pulses per active kWh, the other one pulses at 1000 pulses per reactive kWh. I dealed with the active power only, event though <a href='http://www.5volt.eu/archives/80'>[...]</a>]]></description>

The circuit is very simple and is based and pretty well known building blocks : a pin photodiode <a href='http://www.5volt.eu/archives/63'>[...]</a>]]></description>

This is the radio controlled tank I&#8217;m designing around the Tamiya track &#38; wheel set (p.n. 70100) and the relevant Tamiya twin motor gearbox (p.n. 70097).
I&#8217;m not detailing the model tank design, though I&#8217;m available if you ask, rather I&#8217;d like to show you the details of the motor controller I designed to convert the <a href='http://www.5volt.eu/archives/42'>[...]</a>]]></description>
