Wireless version of the audience wristband
🕑 Added 2023-08-29 00:43:18 +0000 UTCAnother 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.

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.

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