I got into mandalas right as the covid thing hit. My wife eventually asked me what I was going to do with them all (I have amassed quite pile of them). That is when this idea hit me. Sized so that I did not have to use the passthrough but big enough to work. 8 sided (6 sides + top and bottom) Inside there are 3 LED panels 16 x 15 leds each (total of 768 leds). Small trinket M0 board from adafruit drives them. The mandalas are 4 layers thick to allow the openings to be large enough to pass some light. Stand is a hacked ikea lamp , I believe the holmo model. I used cheap printer paper to defuse the light.
By default, it randomly cycles through about 20 patterns. It has a rotary encoder/ switch to allow the user to set the brightness, pick the color, pick a single pattern or have it cycle, select if the colors within the pattern change or not. That part mostly works. I like the random pattern, cycling colors at default brightness anyway. yep the house is a mess. i blame the 3 year old. He blames me.
