Everything can have budget solution, using poor man method, everything can be DIY (Do it Yourself), such as the poor man wifi that I mention long time ago. Even POE, Power over Ethernet Injector and splitter also can be DIY.
DIY POE Injector
Here have a video tutorial on Do It Yourself POE Injector
What you need to DIY POE Injector?
- Power Jack
- Cat5e (RJ45) Crimp head
- Cat5e wire
- Cat5e Keystone Jack
Color Code that must be follow when create DIY POE Injector
- pin 1 orange white
- pin 2 orange
- pin 3 green white
- pin 4 blue (positive wire)
- pin 5 blue white (positive wire)
- pin 6 green
- pin 7 brown white (negative wire)
- pin 8 brown(negative wire)
My Advice on DIY POE Injector:
Please make sure your self do enough research and also have basic knowledge on electrical + Cat5e color code design before you DIY your own POE Injector.
Once the positive and negative wire put in the wrong place, your device might shock or expose.
Coming Up Soon:
With the above information, pin 4 and 5 attach with positive wire, and pin 7 and 8 attach with negative wire? Does this really correct? I will come out a research and experiment to proof out on the correct wiring on Power Over Ethernet injector that supply the power over which cable. So, stay tune.

This worked great! Video does not work. But I did this off the what you need and color code alone. It took all of 20 minutes and I even soldered my power to the white/blue, blue white/brown, and brown. And well I am using the internet now over it. Now I can mount my Linksys Router up to 100ft away from my cable modem and not have to worry about my power supply. Lets see cost? 2 Cat5e Keystone Jacks $10, 2 foot patch cable that I cut in half to have my two pigtails $3, plus solder, power supply, and 50 foot patch cable I already had. So my grand total is… $13 plus tax. (You can find the keystone jacks cheaper online. I bought mine at Lowes)
