Using eight digital inputs, this circuit simplifies decoding of the common membrane 4x4 keypad matrix and eliminates the traditional requirement of scanning rows or columns. Any X-Y switch matrix, ...

The current-mode or peak-current-regulating switching converter is a familiar, almost dominant, power supply circuit consisting of few parts and is usually designed with “cookbook” procedures from PWM ...

The ASUSTOR ASW205T is a basic unmanaged switch, capable of running at 2.5Gbps across five available ports. There's no management panel for fine-tuning settings, nor does it have any other more ...

A previous Design Idea outlined a relatively simple circuit in which a momentary pushbutton could be made to function like a latching, mechanical switch. The article generated a good deal of reader ...
