It’s what we wish our simple circuit diagrams looked like. We like it. Posted in Hackaday Columns, ... these drawings are construction diagrams and are not much instructional as to why things work.

The simple audio mixer circuit is built on common base principle, where input voltages are transformed in alternative currents wich are summed to form the alternative current component for the ...

We can see how circuits work, and represent them with some simple diagrams, using basic electrical components like these. You start with a cell, or combination of cells.

The metal detector circuit shown here must represent the limits of simplicity for a metal detector, yet the design works surprisingly well. It uses just one 40106 hex Schmitt inverter IC, a capacitor ...

Students learn to define and give symbols and units for current and resistance and to draw a simple circuit diagram, using convention current for the direction of the flow of electricity.
