Mystery Widget 2
For the original Mystery Widget, click here: Original Mystery Widget		If you visited our booth at the EOS/ESD Symposium in Charlotte, N.C. in October of 2002, most likely you left with the Mystery Widget 2 in your hand and now you want to know how it REALLY works. Contrary to the first impression, Mystery Widget is not a precision NIST-traceable calibrated instrument. It is more of a high-school science project pedigree. You can even build it yourself – you have our full permission on reverse engineering of this Widget. Mystery Widget 2 contains N-channel J-FET and a generic bipolar transistor. The FET is biased into a non-conductive mode. When both leads of a Mystery Widget 2 touch conductive or static-dissipative surface, the resulting current biases FET into a conductive state. Both LEDs light up. Mystery Widget 2 will not react to static-dissipative materials with very high resistivity, such as pink plastic bags. Now bring Mystery Widget 2 close to your computer keyboard or to the power cord. The LED may turn on. Or it may not. Why? Well, there are mysteries in life and this widget is one of them. However, if you have an inquisitive mind, pick a high-school Physics textbook, or if you are completely desperate, call us at 831-459-7488 or drop us a line -- we will interpret the Widget for you.
