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 ...

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, ...

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 ...

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… ...
