This simple water detector circuit uses alternative voltage in order to prevent the corrosion of the electrodes. It is easy to build and uses N1 as a trigger Schmitt gate which generate the AC. If ...

The circuit is a simple one, and a classic. ... In my example with two BC547C transistors the total current gain is at least 420^2 = 176,400, typically 520^2 = 270,400, ...

A curve tracer for example, the relatively simple circuit allowing the plotting of electronic component response curves on an oscilloscope. Lest we forget this useful device, ...

That circuit can be implemented with only a few low-cost components. It gives practical design hints and tips on designing a PD DC-DC converter stage. It also presents a galvanically isolated, Flyback ...

Shown is an example of a simple circuit (TI reference design PMP9759) that bidirectionally drives current through a TEC; the single-chip buck-boost converter requires a minimum number of components.

A relatively simple circuit invented by researchers at the University of Texas could let smartphones and other wireless devices send and receive data twice as fast as they do now. The circuit ...
