Many tennis balls are used and discarded at the four major tennis tournaments (Australian Open, French Open, Wimbledon Championship, US Open). The total number of the four major tournaments exceeds 230,000, and the Wimbledon Championship alone is said to reach 55,000.
"Hear O" is a project aimed at reusing the tennis balls used at the 2016 Wimbledon Championships. It gives the ball a new life as a Bluetooth speaker and gives tennis fans the satisfaction of owning the ball used at Wimbledon.
The design is simple. The top and bottom of the tennis ball are hollowed out, and a speaker is installed in the upper part and a switch button is installed in the lower part. This may seem like an easy project, but according to Rogue Projects, the rubber used inside the tennis ball has the property of suppressing unnecessary vibration, and the effect is that you can enjoy higher sound quality than you can imagine. ..
Use a dedicated cradle for charging. It can be used for up to 5 hours on a full charge.
Rogue Projects is currently conducting a campaign to recruit investors on the crowdfunding site kickstarter for the commercialization of "hearO". At the time of this writing, one "hear O" is available with a £ 50 investment. Shipment is November 2016.
Rogue Projects also offers speakers made from the autographed ball of 1987 Wimbledon Men's Singles winner Pat Cash. There is one more left at the time of this writing and is available for £ 150. Signball versions by Michael Chang and Lleyton Hewitt were also available, but they are already sold out.
