Electrochemical System 2008

The Electrochemical System is inspired by Gordon Pask’s early experiments with electrochemistry. The central negatively charged copper electrode of each glass is surrounded by four positively charged copper electrodes. Copper dendrites grow from the central electrode reaching out to the outer electrodes. The plates are connected so that each glass is in competition with the other, more charge being consumed by the fastest growing dendrite. Each outer electrode is connected via an LED whose brightness indicates the voltage difference.
This work represents an experiment in using dendritic growth as self regulating switching mechanisms, as a dendrite grows, it consumes more potential in competition with other dendrites trying to grow from the same power source.
Pask describes the possibilities of chemical computing, the energy systems involved and illustrates a number of circuit possibilities for dendritic circuits on pp 105–108 in his book “An approach to Cybernetics”, Pask 1961.
