This is a three stage transistor amplifier circuit that will detect voltage, static electricity, skin, cats, dogs... Nikola Tesla! It's a simple fun project to build that demonstrates how transistors can be cascaded in a circuit.

Electrolytic Capacitor test!by BladeLzo101,227 views
Is there a significance as to the resistor sizes? I noticed the resistances decrease from the first transistor, to the second, to the third.

Have you tried hooking up a peizo buzzer instead of an LED?
