Monte envisaged the component maps—60 in all—being stitched together, and so left detailed instructions for how to turn them into one giant representation of the world, over nine feet in diameter. Included in the four volumes are also charts showing the lengths of days at different times of year and an extended geographical treatise on the world and cosmology. Unlike many modern maps, which use the Mercator projection from around the same time, his map shows the world from directly above the North Pole. Today, this perspective is known as the north polar azimuthal projection, most famously used on the logo of the United Nations.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
