Derelict Electronics: Workshop 1: Amplification

In this workshop we will use a mesh of point contacts connecting to
chalcopyrite and iron pyrite to make crude amplifiers out of rocks.

When an electric current is sent through the rocks sporadic noise bursts
from the speakers. With some fine tuning these rocks begin to behave like
microphones, amplifying howling feedback and detecting subtle scratches
and disturbances in their surrounding environment. Occasionally the
circuit exhibits visual output coinciding with the audible in the form of
small sparks and minute explosions occurring where the copper point
contacts meet the surface of the rock.

This crude amplifier is based on the Adams Crystal Amplifier 1933, a
precursor to the modern transistor, one of the fundamental building blocks
of today's electronic and digital world.
