Mains power switch for exercise bike
This 11-year old autistic boy has plenty of energy and enjoys being active. He has a stationary exercise bike which he enjoys riding. His clinical psychologist thought it would be beneficial if the power generated from riding his bike could be used to operate some flashing disco lights, a cassette recorder and an electric train.
A mains power switch was devised to enable him to power equipment.
Cycling on his bike is now much more interesting.
