When we moved in I had already devoted some time and energy to [...] Continue reading
I could control the mains using a Triac and will probably try an experiment with that later. But using only components that I understand means a relay. So, following the excellent description on SparkFun you end up with a simple circuit with a NPN transistor that switches on the coil of a relay. The description [...] Continue reading
The approach I’m going to take with this project is to design and build each part of the mains controller as independent circuits and evaluate / play with them. When I have them all hooked up in a way that works and that I’m happy with, then I can draw a schematic and board layout [...] Continue reading
