After months of work, MIT students in 1982 inflate a giant weather balloon in the middle of a Harvard-Yale football game. They buried the balloon under 3 feet of dirt, and had the whole thing popped out of the ground with a freon-driven hydraulic piston, and inflated the balloon with a vacuum cleaner motor. They even included instructions on how to dismantle and remove the device so the game could continue. I love the hand-made drawings used to show how the device worked during the press conference.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
