Derek Klingenberg, a cattle farmer and YouTuber in western Kansas, wanted to send a message to space: Specifically, to Elon Musk’s “spaceman,” the dummy astronaut riding in a Tesla launched by SpaceX in February, by herding dozens of cows into the shape of the word “HI.”
Nearly 200 “Dove” satellites owned by Planet Labs orbit the globe every day, taking photos of the earth. Some of this imagery is used by crop monitoring service Farmer’s Edge. This is where Klingenberg wants to show off his cow-art, but he only has past satellites images and the knowledge that they make daily passes in orbit to figure out when and where to position his herd.
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.
