To do turn your old processors into keychains you need: An old processor Needle nose pliers Diagonal cutters A drill a keyring also a pocket knife can be helpful
Step 2: Pin Removal
Now, this is the hard part, removing the pins from the chip. This can be done multiuple ways with mixed results, so feel free to use your own method. I used needle nose pliers and diagonal cutters to remove some pins, then for the rest I used a pocket knife to "shave" off the remaining pins. While doing this make sure not to break the chip. For those who have processors with small balls instead of pins you can skip this step.
Step 3: Final
Now all that is remaining to do is drill a hole in the processor near a corner and put in a keyring in it. If you want you can shave down any corners.
