LED sphere with 194 LEDs and how to build it

Everybody is crazy about LED cubes. I wanted to create one myself, but I wanted to make it an even bigger challenge and since I am not limited by the use of circuit boards and can make it free-form. I’ve decided to make an LED ball. I believe this is the first instance of air-wire LED ball in the world.

It’s controlled by ESP32 board and powered by 1000mAh LiPo battery. So not only it is wearable but also can be controlled via mobile phone.
