There seems to be nothing a 555 can’t do. We’ve seen it before, but [electronzapdotcom] reminds us you can use a 555 and a few parts to make a reasonable touch switch. The circuit lives on a breadboard, as shown in the video below. The circuit uses some very large resistors so that noise from […]
The plethora of smart home devices available today deliver all manner of opportunities, but it’s fair to say that interfacing with them is more often done in the browser or an app than in the terminal.

The list of countries to achieve their own successful orbital space launch is a short one, almost as small as the exclusive club of states that possess nuclear weapons. The Soviet Union was first off the rank in 1957, with the United States close behind in 1958, and a gaggle of other aerospace-adept states followed […]
