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.

The Chaotic Good 🏳️‍⚧️🏳️‍🌈🖖

Hey #DIY #Electronics #circuit folks - I'm working on a project that requires me to replace an SMD component on a circuit board that's going to be in an automotive/motorcycle application (not directly in moisture, but will be outside) - What's good for conformal coatings these days? Any recommendations?

The board is SMALL, and I've got a coating remover pen, but I'm thinking a new coating before I put everything back together will be a good idea.

So many choices...
