Shortly after the development of the electric light came the light switch, presumably. Of course, obvious switches are old-hat, and this neat lamp build from [Giovanni Aggiustatutto] goes with a ...

This is a brilliantly simple smart lighting solution. But it’s also simplistic, lacking the advanced features that smart-home enthusiasts will want. There are ...

With just three transistors, one relay, and some resistors and capacitors, a single light switch can provide sophisticated control of high-power and low-power lamps. With just three transistors, one ...
