To build the DIY electronics projects described in this textbook, you will need a small work area, a few tools, and some basic electronics supplies. This page describes the setup of a low-cost home electronics laboratory.
In this hands-on AC electronics experiment, power a DC motor through a multi-conductor cable to learn how AC signals are coupled between conductors and how to mitigate noise coupling.
This calculator will solve for either distance, time, or speed given two of the three parameters.
