NASA engineers who work on the International Space Station have built a Raspberry Pi-powered ISS Mimic, a 1% scale model of the International Space Station. It’s a 3D printed and has solar arrays, 12 motors and thermal radiators, all fed by live data from the ISS. Here’s more from Raspberry Pi Blog:
The user can also touchscreen-activate the physical model, in which case Raspberry Pi sends the telemetry along to Arduinos, which in turn command motors in the model to do their thing, rotating the solar panels and thermal radiators to the proper angle. The solar panel joints use compact geared DC motors with Hall-effect sensors for feedback. The sensor signals are sent back down to the Arduino, which keeps track of the position of each joint compared to ISS telemetry, and updates motor command accordingly to stay in sync.
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.
