We all know Amerigo Vespucci, the Italian explorer after which the United States was named. But have you ever seen the first map to label parts of the world as America? Created in 1507, the so-called Waldseemüller map holds this distinction. Also known as Universalis Cosmographia, it’s composed of 12 separate woodcut prints that were meant to be hung together. Though German cartographer Martin Waldseemüller stated that 1,000 copies were printed, the last known copy is in Washington, D.C. at the Library of Congress.
The precious map, which was rediscovered in Germany in 1901, was purchased by the Library of Congress for $10 million in 2001, and was symbolically turned over by German chancellor Angela Merkel in 2007. It’s now on permanent display in a specially-designed microclimate case.
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.
