#47 Flower Train Hits That

A combination of two designs from Cherry Hinton School, this invention is able to hit the key frequently and with a one second delay.

Gabrielle’s picture is packed full of ideas, but we especially liked the flower train. We’ve made this work by creating a very narrow conveyor belt, to which we’ve attached the flowers mounted on small blocks, or carriages. As the flowers rotate round the front pulley, they hit a small lever and cause the piano to play.  However, that’s actually quite difficult.  Laura, who did her work experience in our lab, spent some time trying to work out what shape the flowers should be by cutting out models in cardboard. We think we’ve now got the right shape but we’ll have to wait to find out when we start our testing.
