Decoding Slow Scan Television Transmissions from the International Space Station (Listen to the Transmission Audio!)
From time to time the International Space Station (ISS) will activate their Slow Scan Television (SSTV) transmitter. April 12, 2018 was one of those times as the Russian crew commemorated Cosmonautics Day. Getting a SSTV image from the ISS is kind of like getting a FAX sent to you from a spaceship. In the case of the captured image above the ISS was transmitting an audio signal to Earth on a frequency 145.800MHz with 25 Watts. The signal is strong and lets anyone with some basic equipment receive and decode the image.
Now before you press play, I recommend turning your volume down but not off, just barely so you can hear, and then turning it up to suit your tolerance.
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.
