Early soccer balls were hand-sewn and made of leather. They were never perfectly round, and inflating them required some skill. The laces had to be undone before an interior air bladder was filled and tied with a thread; then the laces were retied.
Team captains chose a ball before each match, and every team had a preferred design, according to Peter Pesti, a collector and expert on World Cup balls. In the first World Cup, in 1930, Uruguay and Argentina could not agree on which ball to use. The first half of the match was played with a model favored by Argentina. The second half was played with Uruguay’s preferred design, the T-Model. Argentina led, 2-1, after the first half, but Uruguay recovered in the second and won, 4-2.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
