A DIY Deichkind-inspired tetrahedral LED hat

Arduino TeamJune 11th, 2020

After mechanical engineer “Kuchbert” saw the hip-hop/electropunk band Deichkind perform — wearing LED-embedded tetrahedral hats, no less — he decided he wanted his own glowing geometric headpiece. Now, nearly 10 years and several shows later, he finally got his wish by constructing one out of acrylic triangles with 156 WS2812Bs.

An Arduino Nano controls the device, which links up to an Android app via an HC-06 Bluetooth module, while a portable USB power bank keeps things running.

More info on the fun project is available in Kuchbert’s article. You can also see this brilliant head covering demonstrated in the video below.
