Laser harp makes music
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 that magical laser harp. that 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 whether that view catches on big duration? Makes us wonder what types of harps do angels use now…Permalink: Laser harp makes music from Ubergizmo | Hot: Blackberry Bold 9700 Review
