There are times when one needs to take an digital signal and create the inverse of this signal. Doing this in discrete components can be challenging to fit into a small space. Lucky for us there are ...

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.

IN NATURE of January 30, 1908, some results were quoted by me with reference to the effective inductance of two long parallel wires when the change of current distribution due to frequency is taken ...

Remember learning to tie your shoes or ride a bike? Like many things, that’s easy once you know how to do it, but seems impossible before you learn. [NovaSpirit] asserts that Freecad is simple, and ...

A very simple but highly efficient combination lock circuit is shown in the figure. Any type of on/off switches can be used, varying from commercially available inexpensive types to more sophisticated ...

[Paul’s] project is a great example of how you can take a simple project and turn it into something more interesting. He built himself a jack-o-lantern with an Internet controlled RGB LED embedded ...
