But tiny and onmy desk

 

As far as the hardware that's super easy

 

My question is how do I get mumble to tell my thing that it is transmitting ?

 

Here I would build my ON AIR desktop toy

 

Start with an ESP32, an arduino compatible microcontroller with wifi capability

 

This can easily be powered from a simple usb charger

 

And the only addition is a single RED LED connected to GPIO#1

 

I would put in my wifi credentials and open a UDP port, wait for "TURNON" and "TURNOFF"  messages to control the light.

 

On my PC, I have a script,   onair.bat 

 

You run "onair.bat 1"  it sends the TURNON UDP packet and 0 for TURNOFF

 

All I need is for mumble to execute "onair.bat x" when transmitting/stop transmitting

 

How can I do this in a way that would work both windows and linux ?
