There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total ...

The topic of electricity often poses difficulties for many secondary school students in physics lessons. Researchers have now developed and empirically evaluated a new, intuitive curriculum as part of ...

In the old days every instrument or system had a power supply board with discrete, homemade regulators on it to power the system. Then IC’s like the LM7805 series of voltage regulators changed ...

Team discovers fast, simple way to create two-dimensional electronic circuits that could potentially lead to a new generation of electronic devices. When Northwestern Engineering's Erik Luijten met ...
