Using just two NAND or inverter gates its possible to build a D type (or ‘toggle’) flip-flop with a push-button input. At power-up the output of gate N2 is at a logical ‘1’, ensuring that transistor T2 ...

The previous article examined the concept of logic gates. They can be made from discrete and active electronic components, although today logic gates are available within integrated circuits. In this ...

DNA is often referred to as the building block of life. Now scientists from Imperial College London have demonstrated that DNA (and bacteria) can be used to create the fundamental building blocks of a ...

Memristors, a type of circuit element based on magnetic flux, were first proposed back in 1971, but remained limited to the realm of theory until 2008. That's when some researchers from HP Labs ...

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...

YouTuber Steve Mould has created a great demonstration of computer logic gates using water, tubes, and 3D printed components. This innovative approach provides a tangible and visual way to understand ...

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 ...

According to market sources, Sony plans to release a version of its PSP (PlayStation Portable) using NAND flash from Samsung Electronics in the second half of this year. Save my User ID and Password ...
