Another gift from Vince the crew chief.  A wireless version of the LED audience wristband used in big concerts to add extra audience interaction.

Unlike the infrared version, this one uses a radio signal for control.

Wireless audience LED wristband

The wireless version of the audience interaction LED wristband, given to me by Vince the crew chief for our exploration. These units are issued to the audience of large concerts, and will light up in colours as part of the show. 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. #ElectronicsCreators

That a Pi filter on the output to supress RF harmonics.

Here's one I made earlier - https://flic.kr/p/2oYK8Nk - I don't have a Clive ring light, so off-axis lighting to make the chip readable. Same external, different internals - CMT2210LC RF chip instead of your LH and different selection of discrete components. Presumably one's a clone or evolution of the other. Can confirm mine had 2x CR2032 inside. Oddly, mine has a spring attached to the PCB that doesn't seem to do anything (just contacts the case). The battery compartment has its own spring.
