Making a vibration generator for free (almost):from fizzics.org

A vibration generator capable of a wide range of output is valuable in explaining or researching standing waves and resonance. Commercial equipment is expensive but it is fairly easy to make a generator capable of a useful output at minimum cost.
There is a linked video using this generator here: https://youtu.be/Uvo7uePNV_M
There are supporting notes on resonance here: https://www.fizzics.org/resonance-of-structures/
