Jared has some leftover lasers from a previous project, and deciding to follow the mantra “waste not, want not”, he decided to put them to good use by conjuring this magical laser harp. This fine musical instrument replaces traditional strings on a harp with laser diodes that shine at Cadmium Sulfide photo resistors. Whenever the beam of light is broken, an Arduino will detect the sudden change thanks to the CdS cell, playing a sound via the connected Altec Lansing speaker within its case. Will there be laser orchestras in the future if this idea catches on big time? Makes us wonder what types of harps do angels use now…
