Description
This housing is created for a WEMOS ESP32 board with a 18650 battery holder and an i2s microphone attachment. It fits inside of the sphere, the bottom part needs to be glued inside of one side of the sphere. It depends on the soldering of the LEDs how tight both parts fit into the sphere (how flat are the soldering joints and the wires).
With this solution I was able to make the sphere wireless and sound reactive. It also gives some kind of protection against kids opening the sphere.
