It can be a stretch sometimes to understand the technological justification for wireless charging. At a time when power efficiency is an important societal goal, wireless-charging technology is pretty inefficient.
The Bluetooth-enabled, sensor-equipped 94Fifty basketball makes a good case for wireless charging: Nobody wants a power connector on their smart basketball.
Why put sensors on a ball?
We asked the same thing 5 years ago when we were working to determine how best to measure important elements of skill. It turns out that the ball is simply a receiver of force, and those forces are applied by the player. It goes where the player tells it to go. By measuring all the forces put into or taken out of the ball, and the consistency at which the player can apply forces at game speed, we actually get an amazing picture of how well that player can perform under pressure.
The ball uses the Qi wireless charging technology. Sensor data shows up on a smart phone app.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
