Is it possible to build a WOL dongle?
A nifty solution for autostarting a laptop in the car is using the Wake On Lan option. Most people who have used this hack up a router and wire it to the car and use it to wake the PC.
But that seems kind of inelegant. My question is whether it is possible to build the equivalent of a dongle that would plug into the ethernet jack of the laptop, wire the other end to accessory 12v power and simulate the LAN message to wake the laptop.
Does anyone know how that process works or can point me to a resource that will explain it?
What would be required to do this? Are there a category of off-the-shelf components that can be used or is it even simpler, i.e. a voltage on the line?
I've just read enough posts about auto-turn on of the laptop and was thinking a cool homebrew solution might be cooked up from the talents of our forum members.
Any ideas on this?
