DIY Car and Burglar Alarm

Dr Shini and her team are tasked with reinventing a build-at-home car from the 1930s and a burglar alarm blueprint from the 1950s. In 1936, Practical Mechanics provided its readers with plans of how to build their own three-wheeled car for just £20, the equivalent of £1800 in today's money. The team decide to reinvent this design using recycled parts and a reclaimed recumbent trike. Aeroplane designer Ivan comes up with a novel idea for the steering, an aircraft-style yoke. YouTube inventor Ruth is tasked with welding together the chassis; while carpentry wizard Jacob is building a plywood body to give the car a vintage look. Their do-it-yourself car promises to look impressive, but how well will it perform when it's taken for a test drive on the airstrip? Ruth and model maker Carl are also busy working on their burglar alarm reinvention, which involves some very clever micro-electronics and more than a few surprises!
