This circuit enables the on/off times of a 555 timer to be independently varied over a wide range. This is not possible with a conventional 555 circuit with the RC network being charged from the ...

The circuit was designed to produce a timing scheme that will provide a longer span of time to become activated. LM555 – a highly stable device for generating accurate oscillation or time delays with ...

Over on YouTube [Andrew Neal] has a Function Generator Build for Beginners. As beginner videos go this one is fairly comprehensive. [Andrew] shows us how to build a square-wave generator on a ...

Applications of commercially available integrated timers, including the NE/SE555, are fairly limited when used in their monostable mode. This is due to their inability to function with all types of ...

Nirvaan Tandon started with Snap Circuits at four, learned programming at six, and encountered a Raspberry Pi at seven when he attended Coolest Projects, a showcase for young makers. Now 14, he's ...

This stunning piece of art is [Emily Velasco’s] take on the Atari Punk Console. It’s a freeform circuit that synthesizes sound using 555 timers. The circuit has been around for a long time, but her ...
