I ordered some LED's, sockets, 2n2222 transistors and some 12V relays today.
What do you all think of this plan:
USB->UART (buy it)
UART->LOGIC output (build it: see falstad/video)
LOGIC->RELAY (buy it)
POWER- through relay (spare 12v from shucked HDD's)
Automotive/pinball LED T10 bulbs in sockets mounted to PCB or 3D printed structure. (buy it)

My python code sends data out of the serial port if Teams is On a call and sends nothing otherwise.
The circuit turns the LED red when it sees pulses and leaves it red for a second or so. As long as it gets serial data once a second or so the LED stays on. If anything goes wrong it goes off
Would you buy a serial to on/off GPIO output module like this?

I have simmed and soldered and achieved blinky blinky!
Next step. It's not bright enough. Buying a logic level relay and some T10 LED bulbs. I'm going to try some things.
