When a CPU finally turned out no use, we can make it alive again by methods introduced here.
Step 1: What You Need.
1.A dead cpu. It will always be fine if you'd like to deconstruct a new one.
2.Tools which can make things easier, like a knife.
3.Drill machine (Optional,not necessary if your dead CPU has a hole already).
4.A key ring.
Step 2: Take Apart the CPU.
All the thing you have to do to make this cool key ring pendant is to take apart the cpu and drill a hole on one of the corner. If you have a laser cutter you can also draw something on the key ring such as QR Code.
Just use your knife to remove the copper plate patiently. Alsays remind yourself not to cut yourself.
Step 3: Drill a Hole
In this step, I had some trouble drilling with the machine, but it will be really easy if you have a better drill machine rather than this one from lab.
Step 4: OUCH.
Sorry for my poor English.
