Clandestine Demodulators

2021 

electronic workshop

 

supported by Sonic Curiosities

During this workshop, we will explore the history of Radio transmission and reception to create a series of inconspicuous instruments.

 

By demodulation, we understand the separation of the original signal from the carrier, the disclosure of sound through the means of a crystal. We will explore this technology to understand better how a communication network can be reinforced with simple materials. Inspired by the history of clandestine receivers we will construct radio receivers and embed the circuits into mundane objects. The participants are invited to bring personal objects that can be transformed into demodulating gizmos.
