They describe themselves as the UK's longest running coding and engineering camp for youngsters aged 9 to 17. And they were set up over 10 years ago by Tom Ward. At the time he was a school teacher, though previously he'd been an electrical engineer. But it wasn't long before he gave up his day job to run the camps full time - in London and Hampshire, day and residential. During the Easter holidays Linda saw the young scientists and their tutors in action at their regular centre just outside Winchester.
