Super fast tennis ball
This idea has been brought to life
An invention by Kai Rowntree, age 10, made into prototype form by Carl Gregg at Fab lab sunderland.
“This is a tennis ball that you can adjust the power and make it fast and strong” Kai Rowntree
The young inventor met with the maker Carl Gregg. Carl asked Kai further questions about his design, then started work making a model. Turn the dial to select speed, press in and turn again to select power. Play a game of tennis at your preferred speed. Super fast or slow.
“I thought this was such a fun idea and really captured the essence of a child’s invention. The idea is simple: put controls onto a ball that can set power and speed of a ball in flight. What a great thing to have! Unfortunately, we can’t control gravity or build in mini engines into the ball so it was agreed that this would be a concept model only. The electronics are based on Arduino, which is a fabulous system for anyone interested in getting started with micro controllers.” Carl Gregg
