Step 8Testing testing... 1 2 3...
Flip the apple right side up. Make sure the apple is not coming into contact with any strong electrical fields such as you or a cell phone.
Plug it in.
Nothing should happen.
Now put your hand around it.
It should vibrate.
however...
If you plug it in and it starts to vibrate and never stops then you can have one of many problems:
1. Your wiring is wrong.
2. Somewhere on the circuit wires are being crossed.
3. Ground wires are making contact with your electrode.
4. You have not used shielded cable for your electrode.
5. You have wired your shielded cable wrong.
If you plug it and nothing happens and then when you touch it nothing still happens:
1. Your wiring is wrong.
2. Somewhere on the circuit wires are being crossed.
3. Your chip or transistor may be dead.
4. Your USB cable is busted.
If you plug it in and it vibrates for 10 seconds every time you touch it then you probably are not using shielded electrode wire. The sensor is timing out and recallibrating itself every time it is triggered. Use shielded cable or fix your wiring.

You know a cross-sectional Image(drawing) of where everything should ideally be(inside the apple), will really help the beginners like me. Nice Instructable though.
