An Orrery/Planetarium driven by Raspberry Pis #PiDay #RaspberryPi @Raspberry_Pi
User DeMoor_Orrery on the Adafruit Forums has posted details on a beautiful wooden Orrery:
This planetarium (a mechanical model of the planets in our solar system) consists of 6 planets (Mercury, Venus, Earth, Mars, Jupiter and Saturn) who are in orbit around the sun. Each planet has its own Raspberry Pi Zero W, a stepper driver (Adafruit Motor Bonnet) and a stepper motor (NEMA 17).
On a website any date can be entered after which the website sends out a string with the positions for each of the planets. The Raspberry Pi picks the position up via WiFi, calculates the position and takes the steps necessary with the stepper motor.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
