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 ...

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

Circuit Canvas simplifies the creation of illustrated wiring diagrams. It is designed to be easy to use and fast, allowing users to create diagrams in less than a minute.

While we wouldn’t want to document a computer motherboard with ASCII schematics, it’s great for a quick-and-dirty circuit diagrams.

It’s a pretty clever system with very simple and flexible circuitry. [0033mer] says he’s used this over twisted-pair wires a couple of hundred feet long, which is pretty impressive.

Although this circuit connects the DS18S20 1-Wire temperature sensor to a Cypress CY8C26443 PSoC microcontroller, designers can easily adapt it to connect other 1-Wire devices to any microprocessor.

Find out how to draw circuit diagrams and learn some electrical symbols including buzzer, battery, wire and bulb with this 2nd level Science guide.

Block diagrams are clear, simple diagrams showing all of the input, process and output elements that make up the system being designed. They are easy to read and show how the circuit will work.

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