Hi,
I thought I'd try an experiment based on a transistor; the transistor =
would switch an LED when two wires (one from +5V, other to base of =
transistor) were attached to a conductor of sorts.  It was cool, because =
you could hold one in one hand, the other in the other, and it would =
light up - two, even three people work holding hands :)  Anyway, I added =
another transistor, i.e. transistor 1 takes miniscule current, outputs =
small current, transistor 2 takes small current, outputs slightly larger =
etc. etc.
Anyway, I'm noticing weird results with 3 transistors.. the LED =
fluctuates in a dim state, even with the wires not touching.  Making =
*any sort* of contact with the wire connected to the primary =
transistor's base will light up the LED (quite brightly).  Don't even =
need to be near the +ve supply.  That's touching even the plastic =
insulation!
Anyway.. I don't know if this is called a transistor amp or what, but I =
was just wondering why it does this.. am I naturally generating current? =
:D
