A button that stopped working has probably led to more than a few smashed remotes over the years. Fortunately [pescado99] has shared a beautifully simple cure for dead or dying remote buttons: ...

From self-driving cars to facial recognition, infrared sensors are all around us and our novel semiconductor research is taking this technology to the next level. Phlux - a Sheffield spinout -has ...

The project is designed to control the speed of an induction motor such as fans, by using a standard TV remote. In home automation application, convenience of remotely controlling the speed of the fan ...
