When looking for things to write about, there is nothing we like to see more than well-documented schematics and code available for download. In the case of schematics, we realize that they can be a ...

Here are 4 simple 12V power supply circuits with output voltages around 12V. First power supply circuit is built with BD139, one zener diode and a few passive components. Each of the schematic is very ...

This simple micro ampere meter circuit can help in measuring small currents in five ranges: from 1 µA to 10 mA. The meter is working in this way: the current being measured Ix shifts the input voltage ...

This code was created in 2001-2004 when I taught Borland Delphi 3 to myself. It contains many, many global variables, unstructured and undocumented procedural code and bad variable names. If you don’t ...

Using simple components such as oil, salt water, lipids and proteins, plus routine genetic engineering techniques, it is possible to create simple nanofluidic ...

A simple circuit is a chain of different parts with wires and switches which allows electricity to flow around. All electrical appliances use circuits. For electricity to flow correctly, the circuit ...

The creative new approach could lead to more energy-efficient machine-learning hardware. On a table in his lab at the University of Pennsylvania, physicist Sam Dillavou has connected an array of ...
