Does it ever just kill you that someone in a factory somewhere got to have all the fun of assembling your bench tools? There are a lot of questionable circuit boards floating around the Internet, and ...

A benchtop power supply is a key thing to have for any aspiring electronics hacker. While you can always buy one, plenty of us have old computer PSUs lying around that could do a fine job themselves. ...

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 purpose of the project is to build a power supply that is capable of supplying a variable voltage output from 1.5V to 12V. The purpose of the project is to build a power supply that is capable of ...

The Portable Variable Power Supply features a DC-output that can be easily changed by the user. As its name implies, this power supply is portable, making it invaluable in various circuit projects.

Designers often test prototypes with a variable-voltage bench power supply. If they leave the bench for any length of time, someone may borrow the supply or otherwise change the voltage to a level ...
