Hi, i have a computer screen that is switch on by one of those new kind of switches that is activated either by the heat from your finger or the electricity or some other form of magic. It would switch on or off by itself. I was slightly puzzled by this but i narrowed it down to my plasma ball lamp that is within a meter or so of the switch.I would like to know why this is. My screen model is the samsung syncmaster T260.
One trick with plasma spheres is to hold a fluorescent light near one.The pulsating field around the glass sphere is strong enough to excite the mercury gas inside the fluorescent bulb, which in turn excites the fluorescent coating on the inside of the glass spiral and makes it glow.
