In this episode of DIY or Buy we will have a closer look at a generic AC light dimmer and find out how it functions. Afterwards I will present you a more modern, digital, DIY design of such an AC light dimmer and build it in order to find out whether DIYing such a circuit truly makes sense. Let's get started!
