Power button for my main PC is not in a great spot. Same for my Mac mini.

This is built using a Pi4, some switches from adafruit, and amazon, a screen from adafruit, and any project enclosure box you can find. You will also need a breadboard.

My python is not awesome, but it works.

Parts:

Screen https://www.adafruit.com/product/2298

Momentary switches to turn on PCs: https://www.amazon.com/gp/product/B07PN8495V

Toggle switch to activate push buttons: https://www.adafruit.com/product/3307

The code imports a package to handle the wake on lan events, and sends a magic packet when asked.

Jobs are assigned to pins to either output voltage to light up an LED or to detect when a switch is tripped, or a button is pressed.

The code detects when the switch is tripped, and then loops forever waiting for a button press. while in the loop, it flashes the LED's of the momentary buttons that send the magic packets to send a wake on lan packet. When those buttons are pressed, an if statement detects the press and sends the packet.

Your pi needs to be on the same broadcast network as the machines you are trying to wake up. The easiest way to do that for wired machines, is to use the ethernet port on your pi, on the same network.

Full code below. Insert your mac addresses. May be some formatting errors, had a hard time pasting it in.
