“Supplino is a Quick & Dirty PSU (Power Supply Unit) made with some widely available breakout boards, an Arduino Nano (or an Arduino Nano Every) and a graphical LCD. Power output is given by a DC/DC ...

You may think you’ve built a power supply for your bench. Heck, we all do. But until you check out [Denis]’s bench power supply build, you may not even know what you’re missing. [Denis]’s design is ...

As is common among some hackers, [Henry] re-purposed an ATX power supply unit to function as a bench power supply for testing circuits on a breadboard (much like this fancy example). However, safety ...

Power supplies are among the most popular pieces of electronic test equipment. This isn’t surprising, as controlled electrical energy is used in a tremendous number of ways. The term “bench” or ...

Although variable dc power supplies might appear to be relatively simple instruments, engineers rely on them to deliver stable, precise, and clean voltages and currents, regardless of the load. To ...

The first instrument which comes to the mind of most engineers when it comes to testing a new board is an oscilloscope. While that will help to assess many aspects of the board’s performance, it’s not ...
