Sinclair C5 the event they did not, the project could not continue, due to thermal problems. Neither the C10 nor the C15 ever left the drawing board. Although Sinclair went on to produce more (but much smaller) electric vehicles, the C5 debacle did lasting damage to the reputation of subsequent EVs in the UK, which the media routinely compared to the C5. It was not until a highly regarded manufacturer, Toyota, launched a serious and well-received vehicle in the 1990s, the Prius, that the C5 "jinx" was finally laid to rest.

Sinclair undertook a survey for "Instrument Practice" of semiconductor devices, which appeared in four sections between September 1962 and January 1963. His last appearance as assistant editor was in April 1969. Through UTP, Sinclair had access to thousands of devices from 36 manufacturers. He contacted Semiconductors Ltd (who at that time sold semiconductors made by Plessey) and ordered
