Entropy Broadcast is made from a microcontroller and a strong amplifier, is powered by two 9-volt batteries, is built on a broken Archer Universal Breadboard, and is encased between two acrylic plates. The copper paddle hanging off the side is conductive, meant to be held while the machine is in use. Holding the paddle, the user becomes a large antenna.
The amplifier circuit was deliberately misbuilt to be noisy. The signal it amplifies -- which is then broadcast through the user-antenna -- is a combination of ambient electromagnetic noise generated by the components of the amplifier, cosmic rays, the earth's magnetic field, television broadcasts, radio broadcasts, cellphones, and the small computer of the board itself. The computer runs continuously switching the amplifier on and off to transmit the message, in Morse code, "CHAOS NEVER DIED".
