Robots make radios (1940s style)

No part of ECME itself has survived, but in the 1960s John Sargrove gave the Science Museum several experimental radios he had made to test the system, together with specimens of the ‘sprayed circuit’ panels produced on ECME. These objects, at present in store, remain as a reminder of a brave and pioneering venture in automated production.

Sargrove began his experiments into sprayed-circuit radio manufacture in about 1936. This is an experimental receiver he made either that year or in 1937.
