This simple logic probe has both LEDs on with no signal at the input but due to the nor gates connected to the probe, indicates correctly when a high or low signal is present. It also works correctly ...

In a proof-of-concept study, researchers have created self-assembled, protein-based circuits that can perform simple logic functions. The work demonstrates that it is possible to create stable digital ...

Invigorating the idea of computers based on fluids instead of silicon, researchers have shown how computational logic operations could be performed in a liquid medium by simulating the trapping of ...

This is very simple and useful project which gives an idea about how to build the simple logic gates i.e. AND, OR & NOT gates using one of the universal gates – NAND Gate. This is very simple and ...

It’s time to do a series on logic including things such as programmable logic, state machines, and the lesser known demons such as switching hazards. It is best to start at the beginning — but even ...

When [Marco] was planning on a storage oscilloscope build, he realized having a small device to display eight digital signals on an analog scope would be extremely useful. This just happens to be the ...

One of my favorite silly poems is “The Deacon’s Masterpiece,” by Oliver Wendell Holmes. It tells of a wonderful one-horse carriage, built in “such a logical way, it ran one hundred years to the day, ...
