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

Unfortunately, diagrams of even simple circuits are often unnecessarily complex, making understanding brain connectivity maps difficult.

Due to the advantages like low voltages, long life, cheap, reliable, fast on-off switching etc, the LED's are used in many applications.

For simple circuits, it’s easy enough to grab a breadboard and start putting it together. Breadboards make it easy to check your circuit for mistakes before soldering together a finished prod… ...

This animation shows how pairs of dangling bonds can serve as atom-sized binary bits in digital circuits.

[mikey77] wrote an Instructable showing how to print circuit boards and create simple circuits, using shape of the plastic as a way to control the circuit.

Low-power circuits commonly use transformerless power supplies. However, the use of earth grounds in many of these circuits creates a serious problem that is often ignored. The very popular ...

Figure 1: Simple threshold circuit – which does not work with some references! When I designed this circuit I assumed that if I used 1MΩ as R fb the current (approx 10μA) flowing into the reference ...
