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.

This workshop is limited to ten participants. No prior experience with
electronics is necessary. All materials will be provided.

Cost: $30, students $25
