For some time I was struggling with an ambitious project, to write a Mac driver for my Agilent DSO-X 2002A oscilloscope (see here). The reason behind this is SCPI and the opportunity to reach fresh perspectives in computer–measurement instruments’ integration. However, it was not an easy way. More of a reverse–engineering project, was very time–consuming …

I added a new category/ topic on this blog because last week I successfully passed my Ham Radio certification ! This is something I wanted to do for a long time but had not much time to study and prepare for the exam. One of my relatives was a long time experienced class I Ham …

I was struggling for some time to make my Mac communicate by USB with Arduino. It is part of a larger project of an USB-controlled Lab PSU that I am currently in prototype stage. Part of these problems solved when I finally realized that you cannot use an Arduino as an USB controller simply because …
