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

• x4 MOSFET relays OMRON G3VM-61A1.
  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 and buy an OMRON. 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.
