In honor of Geek Crafts month on CRAFT, we put up Brookelynn Morris’ LED Hula Hoop tutorial on Make: Projects.

LED hula hoops are so beautiful to watch, and creating a custom hoop is a satisfying challenge. Twenty-one LEDs are used in this hoop; 6 are flashing LEDs that cycle through the colors of the rainbow. Each light is combined with a resistor and then wired together in a classic and simple parallel circuit.
