This site is dedicated to sharing personal and public circuit designs so that the engineering community can make modifications to the designs as a pathway to new innovation. They post many public ...

Xtreme Circuits is a blog devoted to using circuits for a variety of applications, whether it be for toys, games or electrical devices. With each project post comes a detailed write up of what the ...

The basis of almost everything we discuss here on ExtremeTech is the transistor -- but just above that is a topic that we usually skirt around because no one, even hardcore nerds, really know anything ...

This course covers the designing and building of advanced electronic circuits and systems. The approach to design is through advanced application of sensor interfacing, instrumentation and low-noise ...

Water molecules distort the electrical resistance of graphene, but a team of researchers has discovered that when this two-dimensional material is integrated with the metal of a circuit, contact ...

Scientists have engineered one of the world's smallest electronic circuits. It is formed by two wires separated by only about 150 atoms or 15 nanometers. A team of scientists, led by Guillaume Gervais ...

Block diagrams close block diagramA diagram of a system represented by blocks connected by lines. are clear, simple diagrams showing all of the input, process and output elements that make up the ...

Process devices operate when an input level, such as voltage, reaches the required value for the device to operate. The transistor is on, when the input voltage is greater than or equal to \(0.7 V\).

(Nanowerk Spotlight) Circuit boards form the foundation of modern electronics, but their production relies on materials that persist in the environment for centuries. These boards must meet precise ...
