With no external components, a 555 can be turned into an oscillator that runs typically in the range of 1 to 2.5mHZ –or who needs a timing capacitor? It is essentially a stripped down version of the ...

A relaxation oscillator is an oscillator based upon the performance of a physical system’s resending to equilibrium after being disturbed. It is a dynamical system within the oscillator continuously ...

It is a pretty common first project to use an Arduino (or similar) to blink an LED. Which, of course, brings taunts of: you could have used a 555! You can, of course, also use any sort of oscillator, ...

[Eric Wasatonic] had a box of SWB2433 transistors that he had very little information about. In order to discover their properties, he fired up his curve tracer to compare these transistors with more ...
