Video summary Mwaksy and Greg construct a simple circuit that uses cells, wires, bulbs and wires and investigate how a switch opens and closes a circuit. After making an imaginary super-sized ...

A simple op-amp circuit placed between a transformerless circuit with a ground tied to neutral and a circuit with an earth ground will eliminate the safety and noise problems associated with such ...

2) LED as a Continuity tester: The above shown circuit is LED as continuity tester. This circuit is used for checking continuity of cables, connectors and switches. When A and B terminals are shorted, ...

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

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… ...

One of the problems encountered thus far with 3D-printing circuits with conductive filament is that it doesn’t really bond to anything, let alone solder, so how does one use it? [mikey77] wro… ...

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 ...
