Cuttens pendulum recorder for psychical research

John Cutten's pendulum recorder (general view above, close-up below), for use in psychical research. This electronic device detects the movements of a pendulum which are recorded on the chart. When the pendulum moves, an electrical current is generated in a photocell and amplified by the unit feeding the recorder. Date: circa 1970s
