Did you already connect it to your wifi network? If not: search for a wifi network "FPP" with password "Christmas". You should be able to log in and change the wifi settings.
What do you want to know? The dress had about 1500 leds in total (500 pixels). Was driven by 4 buck converters, 2 for the skirt en 2 for the body. It was made in two pieces because of the requirement to quickly dress otherwise. It has a couple of powerinjection points. The electronics side is...
I used 2 wemos D1 with a null pixel from Hanson electronics directly at the wemos. 1 for the skirt and one for the body/headpiece.
Had 4x 4s2p homebuilt 18650 packs to power it. 2 packs mounted to a belt for the skirt and 2 on a mini backpack for the body and headpiece
The spacing is 10cm in X direction and 9.6cm in Y direction. It was originally meant for a amateur musical play "joseph and the amazin technicolor dreamcoat", but corona postphoned it by at least a year....
