Project Scope: Use POE to power the r-pi
Project Materials:
R-pi
POE capable switch
RJ-45 Coupler
Coax power plug and wire
Soldering Iron
Solder
Project Description:
We know that at this point in time the R-pi is not capable of being powered off USB, but why shouldn't it be? The goal of this project is to take a POE capable switch/router (or make one yourself, I've seen a few on Google), send power down the ethernet connection and then spice that to the power port!
Project steps
1) Set up your POE switch/router
2) Plug one end of ethernet cable to POE source
3) Modify RJ-45 Coupler
3a) Open up the RJ-45 coupler
3b) Find wires that POE sends power down and cut them!
3c) Drill a hole in the side of the coupler and slip in your wire coming from the coax power plug
3d) Solder the positive and negative wires from the coax power plug to the positive and negative wires in the RJ-45 coupler. then cover with tape
3e) Take the wires loose wires from the r-pi side of the coupler (the wires that were once attached to the POE power but we cut) and tape them off (we don't want them touching and causing problems)
4) Attach ethernet cable from r-pi to the coupler
In theory this should allow you to power the r-pi from a POE device and still also be able to receive data over the cord as well!
