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 ...

Their embeddable schematic window can be rendered in full screen mode, and gives users the ability to zoom in on any portion of the drawing to see the circuit’s finer details.

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.

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.

Explore simple electrical circuits and different electrical symbols with Dr Bigbrain and Horrible Science.

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

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.

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