Sinclair worked by finding ways to make electronics much smaller. In 1972, he created the Sinclair Executive pocket calculator. This device was very slim compared to other calculators. Later, he focused on making home computers that were cheap. He wanted to beat high prices from American and Japanese companies. He did this by using inexpensive microprocessors in his designs. This allowed more people to own a computer at home.

Sinclair's journey began with a strong family history in engineering. His father and grandfather were both engineers at a company called Vickers. Clive was born in Ealing, Middlesex, in July 1940. During World War II, he and his mother moved to Devon for safety. He was very good at math while attending school. Even as a young student, he earned money by mowing lawns. He also wrote his first articles about electronics while still in school.

Many of his big ideas happened through his companies. He started Sinclair Radionics Ltd in 1961. This company made things like the Black Watch wristwatch in 1975.

He later started Sinclair Research Ltd to build computers. His ZX80 computer launched in 1980 for under £100. The ZX Spectrum came out in 1982 with color output. These machines became very popular in the UK and the USA. He also worked with a company called Timex in America.

Not every invention that Sinclair made was a big success. He created the C5, which was a battery-powered electric vehicle.

The C5 did not sell well in the market. He also tried to make a handheld flat-screen TV. These failures meant he had to sell his companies by 1986. Later, he focused on small transport like the A-bike. This was a folding bike that could fit in a handbag.
