Well, place some electrodes on your skull, amplify it with an outside electric current and yes, you can move needles. Your brainwaves diminish to imperceptible levels just millimeters outside of your skull, so the chances that you will be able to have an effect on an outside object because of electromagnetic radiation from your brain is pretty much null.
However, my friend has one story: She was falling asleep with her head on her mom's lap. Her mom had her hand on her head. As she fell asleep her mom claims that she distinctly felt her brainwaves change. Just a sensation in her hand. Was this a telekinetic effect? Hard to say. Perhaps it was not the brainwaves but a syncronized dilation of the sleeping girls pores, release of sweat, or prickling of the tiny hairs on her forehead. There may be some other physiological reasons for what her mom felt.
My friend's mom is a human EKG machine? Maybe.
My friend bending spoons with her brainwaves? Not a snowball's chance in hell.
<edit> BTW, I was not the one to claim I had an experience. I voted "I am a skeptic" since I don't believe that what the girl's mom felt was brainwaves.
