TeleBall is an Arduino based retro handheld game console. You cannot buy it. You need to build it by yourself. It lets you play BreakOut in single-player mode using one device and Tennis for Two in multi-player mode using two devices communicating via radio.
TeleBall is pretty retro and very minimalistic: It features an 8×8 pixel LED matrix display, a paddle as game controller and one button. Therefore, the range of possible games is limited but you will be surprised how much fun and even zenlike meditation this kind of gameplay can bring you, particularly when you play Tennis for Two with a friend.
1.2″ 8×8 Matrix Square Pixel – Blue: Make a scrolling sign, or a small video display with this 8×8 square gridded blue LED matrix. Only 1.2″ on a side, it is quite visible but not so large it wont plug into a breadboard! 64 blue LEDs are contained inside the plastic body, in an 8×8 matrix. There are 16 pins on the side, 8 on each, with 0.1″ spacing so you can easily plug it into a breadboard with one row on each side for wiring it up. (read more)
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
