Rubens Tube is a classic physics demonstration which shows how standing waves are generated within a resonant system. In this video we take that demonstration to the next level by adding a Xylophone interface which changes the driving frequency and creates varying flame patterns when struck. We introduce a method of capturing a drum hit and safely feeding it to a micro controller&rsquo;s input as well as how to create sine waves from a pulse width modulated signal.</span></p> <h2><span

demonstration which shows how standing waves are generated within a resonant system. In this video we take that demonstration to the next level by adding a Xylophone interface which changes the driving frequency and creates varying flame patterns when struck. We introduce a method of capturing a drum hit and safely feeding it to a micro controller’s input as well as how to create sine waves from a pulse width modulated signal.</span></p><p
