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!

Step 1: Watch the Video!

The video gives you all the information you need to create your own DIY AC Light Dimmer. During the next steps though, I will present you some additional information.

Step 2: Order Your PCBs/Components!

Here you can find the link to my EasyEDA file, where you can export the gerber files and thus order the PCBs:
