Matt Gray has a great blog post on how to receive weather satellite images with a software-defined radio. Using an inexpensive USB radio tuner Matt runs software that can control how the radio is tuned and use it to listen to weather satellites circling the earth above him. Even with an inexpensive tuner and makeshift wire antenna Matt is still able to pull out some very interesting images from the satellite’s radio signals. Check out the post for all the details on the software Matt used–nice work!
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
