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 ...

The circuit diagram of the Class 0 circuit (Figure 5) consists of six components that cost about 12 cents (at high volume manufacturing pricing) in materials. A less expensive (but lower efficiency) ...

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.

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

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.

Testing relays and their circuits in vehicles doesn’t always require a trip to the bench. With a few simple tools and ...

Its role is simple and the wiring diagram has been in hand for decades. Still, the circuit has mysteries to offer.
