Simply Electronics

Simply Electronics is an electronics education channel made by an electronics repair engineer. His day job involves diagnosing, repairing and testing industrial automation electronics, from motor drives to power supplies and programmable logic controllers.

The channel is best known for its numbered “Electronics Basics” series. Each video takes one component or idea, such as a diode, a rectifier or pulse width modulation, and explains it with simple diagrams and real circuits on the bench. The pace is calm and the explanations start from first principles. Later videos move into intermediate topics and some 3D printing.

Some highlights include:

A step-by-step guide to how a breadboard is wired inside and how to build circuits on one without soldering.

An explanation of how a boost converter raises a DC voltage using an inductor, a switch and a diode.

A walk through how rectifiers turn alternating current into the direct current that electronics need.

The channel has around 247,000 subscribers. Its most popular lessons have each been watched more than a million times.

For anyone curious about electronic engineering, this is a gentle and practical place to begin. The topics line up well with GCSE and A level physics, and with the first year of an electrical or electronic engineering degree. It also shows the kind of hands-on fault-finding that maintenance and repair engineers do every day. Viewers can follow along with a cheap breadboard and a handful of components.
