Light Ring as show-art and photo-art
As playing around with the neopoixels/addressable LED’s the idea strung that it would make pretty nice pictures if they are the only light source.
The result of pictures can be seen below where the photo is taken through the ring.
The ring is simple constructed from a PVC pipe use for pluming installations and a conduct box for electrical stuff. Inside is a WMOS controller with a build-in 18650 battery holder. This controller has a BMS system build-in for changing the battery when a power source is connected. With the battery build in, is able to run for 10-15 min for taking pictures.
