A Planet Analog article, “ 2N3904: Why use a 60-year-old transistor? ” by Bill Schweber, inspired some interest in this old ...

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 ...

CMOS relaxation oscillators have emerged as a pivotal technology in modern integrated circuits, offering a balance between low power consumption and simplicity of design. These oscillators utilise the ...

Surface tension becomes more important as objects become smaller and it is the dominant force on the micron scale and below. This is why, for instance, insects can walk on water whereas humans cannot.

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, ...
