Some time ago I also completed this project that I never got around to publish. This project is a WiFi-Infrared gateway. I am aware that such commercial products exist, but at the time I needed one for my home the available options all suffered from one or more shortcomings, such …
I must have thought there were not enough kinds/shapes/etc clocks in the world. Or maybe I thought: “I made one in the eighties, one about 10 years ago, so it is time for another one.” I’m not sure at this stage. What I do know is that I wanted to …

Introduction For a number of my upcoming projects I need a rig to test the functionality of a solid state relay that would be driven by a microcontroller and switch the mains for other devices. Having done projects with similar requirements in the past I remembered how much pain it …
