Step 1: Find the Copy Machine and a Paperclip
I found this system in 2 seperate college campuses, and I usually keep a paperclip in my wallet, very usful little guys. Paperclips are so freaking useful, PROTIP: keep one with you.
Step 2: Locate the Cables for the Coinbox
The 4 conductor cable (black, red, white, green) is what we are interested in, while the 2 conductor cable is connected to a wallwart supplying power to the coin collection box.
Step 3: TEH H4X!
Insert one prong into the connector conduit containing the black colored wire, and then the other end into the red.
Step 4: Verify
Step 5: Be Respectful
Make some crazy cool art out of xerox copies! (No, I dont have lepersy)
