Every year my employer throws a large Halloween party on site, work stops the day before so that things can be setup. I thought that creating a little boombox to play music, along with a string of ws2812b's to play along with the music (LEGO movie theme)

Unfortunately the box build failed (shockingly, pallet wood is not the highest quality product)

Also, I gave up on the esp8266 in this project. Using ESPixelStick, no matter what config I use to connect the ws2812b's, I get a large flicker that is not present when an Arduino is used.
