[Andrew Gibiansky] has just started a tutorial series called Computing with Transistors. It’s purpose is to pull back the many veiled layers between high level languages and the controlling of ...

I've covered tons of different scientific applications you can run on your computer to do rather complex calculations, but so far, I've not really given much thought to the hardware on which this ...

It may seem a paradox, but in the future tiny computers may dump electronics and return to their mechanical roots. At the macroscale, mechanical computers are fussy and slow, but when your area is ...

Using digital logic gates such as AND, OR, XOR, NOT, NAND, NOR, and XNOR and other related logic functions is often the foundation for defining the relationship between electrical signals and how they ...

Oscillators, also called astable multivibrators, are electronic devices that generate a periodic signal. They are employed in a large number of applications such as clocks, oscillophones, musical ...

The ability for cells to control gene expression in response to changing conditions is crucial for their survival. People spend their entire careers teasing apart these mechanisms, many of which are ...

Researchers from McMaster University and the University of Pittsburgh have created the first functionally complete logic gate ...

A collection of transistors and resistors that implement Boolean logic operations in a digital circuit. Logic gates have one or two 0 or 1 inputs but only one 0 or 1 output as in the following ...
