Hey, i have some questions about your setup:
Did you measured the latency which gets introduced by the streaming system?
Are there maybe some parts which can be improved?
I noticed that the Buttons are controlled by an raspberry. Is the raspberry connected via wifi? (2.4 or 5 GHz?)
What is the path of the signal from my keyboard to the relay controlling the pinball machine?
Grate work! Greetings, ze
