With this part, you will be able to remotely turn on, turn off and restart your computer!
- x4 optocouplers

Don't use random relay modules or random optocouplers! Some of these may not be sensitive enough for the Raspberry Pi, some others may be low-level controlled. Either use relays that are activated by a high logic level, or follow the design provided. See details here. - x4 390 Ohm resistors (see here for alternatives).
- 2x 4.7 kOhm resistors.
- x10+ dupont wires male-male.
- x1 a breadboard.
- various wires for the breadboard.
This can be partially replaced by using Wake-on-LAN in the software, but it will not allow to reboot a hung system, and it is not as reliable as an ATX controller. Sometimes the Wake-on-LAN on the host just stops working, for its own or network reasons.
