Since the Xyloband was used on Coldplay concerts in 2012, the use of interactive audience illumination gadgets has become common in the entertainment industry.
Update. I tried a set of new AAA cells in the unit, hoping for a self test sequence, but it stayed unlit. It needs to see the correct IR codes to operate.
This unit is a Pixmob band that can be given a specific identification code and is controlled by high power infrared floodlights in the lighting rig that transmit control data when triggered by the lighting desk.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- https://www.bigclive.com/coffee.htm
This also keeps the channel independent of YouTube's algorithm quirks, allowing it to be a bit more dangerous and naughty.
