The circuit itself is a light-activating chirping circuit built with 7400-series logic and installed in the hollow of the bird. The sensor is in the nest, and sounds like the baby birds beckoning ...

In this project, I'll make a small circuit capable of controlling a servo, it is a servo tester made out of a 555 timer IC.

Discrete noise reduction circuits Over the intervening years between the first regulators and the newest low-noise varieties there have been a few discrete circuits that have cropped up to lower the ...

Figure 1 Make your own milliohmmeter, using a voltage-regulator IC and some resistors. IC 1 controls the base of the npn Darlington transistor, Q 1 . The IC regulates the voltage across the selected ...

A simple electric circuit learns to classify data in a creative new design that could lead to more energy-efficient machine-learning hardware.

Using the simple circuit shown in the figure, you can boost the drive from these power ICs and maintain current limiting. In this circuit, the power FET for +12 V in the hot-plug power IC isn't used.
