>> 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 << Your circuit now has such high gain that it is sensitive to signals picked up from the environment, like 60Hz power line noise and radio stations. Try this. Make sure you are will insulated from everything else and touch the wire. The LED will light up because your body is much better at picking up the stray signals than the little wire, and these stray signals are being amplified. Now touch circuit ground with the other hand. The LED will probably go off. You may be able to adjust its brightness by how hard you grip the ground connection. Connecting your other hand to ground should still work thru a small capacitor, like 100nF, proving that these are AC not DC signals. Another interesting thing to do would be to look at the waveforms after the first transistor stage. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
