Adafruit is back again with another awesome DIY project. Their LED Trampoline makes you want to jump some more. The trampoline is enhanced with LEDs that light up as you jump. It looks especially cool at night. You are going to need an Adafruit ItsyBitsy M0, vibration sensor switch, battery pack, LED strip, and a few other components to get started.
The files and instructions for this project are available here.
