I was taking apart a computer for the dead computer contest and i found a big computer chip. The chip is an intel pentium icomp. The pins are not very sharp and when rubbed against the skin relieve the itch. I also found a metal slot and 2 ram cards which had holes on the ends.
Step 1: Tools
The tools for this instructable are simple:
-A pair of pliers
-Hot glue gun
What you need to make the back scratcher is:
-Large computer chip
-2 ram cards or other long and thin computer pieces
-Screws and bolts, i got mine from the computer
Step 2: Taking Apart the Computer
This step i s simple: do what ever you need to get to the inside of the computer with out completely destroying the inside components. Once you have done that get what you need you can do what ever you want with the rest.
Step 3: Assemble the "arm"
To assemble the arm of the back scratcher you will need the ram cards and the metal port. Connect the ram cards first and make then straight. You could leave them a little loose and that would allow he arm to bend. Then attach the metal port withe the other screw and nut. The arm is done.
Step 4: Attach the Computer Chip
The way i attached the computer chip is by hot glueing it to a ram card on the arm. You do not want to glue the entire chip to the card, instead glue the chip to the card about one third of the way on the chip. Now you are done. The only thing now is to try it out.
