Man spends 50 years recreating The Thing spy bug
The 79-year-old said he was so "fascinated" by it that he became determined to make a new version of the bug, which had no wires or batteries and had passed unnoticed in the office of the US ambassador in Moscow.
The documentary, called The Thing, will preview at the National Museum of Computing, at Bletchley Park, Buckinghamshire, on Saturday.
Mr Little said that after working on The Thing recreation, he started on "the 2024 version".
"This one incorporates internet, 4G, sat-phone technology, which gives us the ability to remote control the system so now it has a range of 12,500 miles - half way round the Earth," he said.
