The archive presents 3D models of 11 globes — a subset of the library’s historic maps collection — that can be rotated and zoomed into for greater detail at every angle. This includes a stunning 1602 celestial globe by Dutch cartographer Willem Janszoon Blaeu, first produced in 1602. In addition to representing the constellations as their fantastic and mythological namesakes, it identifies a nova in the constellation of Cygnus which Blaeu had personally observed in 1600. It’s one of several celestial globes in the collection — some of which pair with terrestrial counterparts — and all of which are fascinating examples of globes that do not represent terra firma or spaces with fixed positions at all, and indeed capture only a brief moment in the relationship of celestial bodies.

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.
