Wolfie wanted to build a costume for his 12-year old granddaughter for this Halloween. He settled on the idea of a giant wearable disco ball (as you do) and set about building it out of suspended ceiling hanger wire. He added chicken wire and a looooot of duct tape to the framework and then embedded 288 WS2811 LED pixels. Into the mix is thrown a Raspberry Pi 2 to control the sequencing of the LEDs and a level converter to protect the Pi. The Pi itself is powered from a portable power bank, whilst the rest is driven by a drone battery. You can read more over at Thingiverse.
