The latest Raspberry Pi 3 Model B+ isn’t so “revolutionary” but is filled with custom silicon, new technologies, and it even has a neat embossed RF shield. On the Raspberry Pi blog, James Adams has introduced the MXL7704, a custom chip to supply all the voltages found in the Raspberry Pi, just in time for…
After many hours studying Arduino programming and thanks to the support of the Arduino Forum.cc community, the maker MBcreates was able to build his first Arduino project: a digital air pressure regulator. “Simple is often better. So I grab an old blowgun and used this a valve. The Arduino Digital Air Pressure Regulator uses a…
Some time ago we had introduced you to the Torpedo switching power supply, a particular kind of DC/DC power supply called SEPIC capable of supplying 5 V from several external supply sources, such as an external voltage between around 3.5 and 20 V, the 5 V coming from a USB connector or the 3…
Having explained the theory, let’s see in practice the project of the SEPIC power supply. In this post we discussed – on a theoretical level (even if in a simplified way) – the SEPIC switching converters, also highlighting advantages and disadvantages, and giving you the basics for the calculation of their components. Let’s…
The SEPIC configuration, a very useful one, is used in modern converters for mixed supply systems. Thanks to the availability of an always growing number of specialized integrated circuits that realize – with the help of very few external components – some complete and valid voltage regulators, today the switching technology is the most…
The possibility to transfer electric power by means of electromagnetic waves was proved for the first time by Nikola Tesla, in 1890: he probably could not imagine how the discovery would have been appreciated nowadays. Standard Qi and wireless charge are terms that overwhelmingly entered the consumer sector, and in particular as for…
Very interesting solution to have for only $35 a full power station, really usefull when testing your self made boards. And with interesting features, as you can read here: The PowerG gives you the ability to control power like the expensive bench top power supplies. It provides two outputs: 5V-12V and 1V-3.3V. You have a…
