Here is a cool lighting system that lets you put on a light show while playing drums. Neptune is a sound triggered solution with selectable colors, adjustable sensitivity, and fade modes. It detects sound from inside the drum, allowing you to adjust its settings so hitting a drum does not set off lights on other drums. Neptune has 3 lighting speeds.
The Neptune Drum Lighting system is easy to install and has flexible mounting options. Like what you see? You may want to support the project on Kickstarter.
