Here’s a cool DIY cardboard laser piano by ElecFreaks:

Hi Guys, today, ElecFreaks will show you a guide how to make a cardboard laser piano by yourself. By this way, I think you do not only could make piano , you can transform a table , a window or a wall to be a Laser Piano or a Laser Harp .
The Cardboard Laser Piano was based on Arduino UNO, with photosensitive modules, laser emitting diodes, JQ6500 voice module combined, the simple electronic piano detects high-low level current outputted by the adjustable photosensitive modules via laser radiation, thereby sending different orders which represent different notes to JQ6500 module. Users can replace notes and songs anytime, only they’ve downloaded the pre-recorded audio into JQ6500 module in advance.

Via the contact form.
