“Once again a project realized in the B&B during my free time, far from home. The circuit described here will be capable to drive almost any device that currently uses an IR remote control, by means of WiFi connection, as to say: with your smartphone. This time I want to show all the route from the idea to the running device. I had the idea some years ago (look at my previous articles regarding IR and WiFi), but I completely forgot it until today.
When I start a new project, there is the first step that I call: “sofa time”. I spend such time lying down on the sofa, without any computer, pen, document or tool. I just think about how to realize the project with the minimal effort.
After this time, I take a block-notes and draw with a pencil (or a pen) a very minimal schematic. In practice, it’s just a brief list of essential connections for the various components that I’m going to use.”
