I haven’t uploaded the video yet,

but to get you going:

It can be powered by either 4 x AA batteries, or a power bank with a USB-C cable.

If using a power bank, the on/off switch is bypassed and is not needed, and it will calibrate straight the way.

When it calibrates the music box will play for around 10 seconds, once it has finished calibrating the music will stop.

When the motion sensor picks up movement it will play the music box.

It has a range of around 7 meters.
