Tired of spending money on POE injectors ?? Found a nice simple method to do your own POE... so simple

Just a word of caution, when you dont use the ether for POE, and you want to connect pc to it, remember, voltage wil come back from the DC jack to the ether (as opposed to power coming from the ether to the dc jack) and quite possibly blow your motherboard's onboard LAN.

I had this happen to me a while ago.

I would add a diode in between the DC jack and ether pins ( Orientation important) to stop power from DC going to ether.

just dont connect that end! only need the 4 wires on PC / Hub end...

Somewhere along the line you will forget/someone will not know.... Build the protection in, gonna save a NIC sooner or later.

Cool, but POE injectors are cheap anyway, so why bother?

PoE Passive Splitter + PoE Injector is just under a R100 incl. and you don't even have to open the little WRT54GL.
