Bastian Bloessl has ported the latest version of GNU Radio to Android including some new features.
Some months ago, I looked into Tom Rondeau’s work on running GNU Radio on Android. It took me quite some time to understand what was going, but I finally managed to put all pieces together and have GNU Radio running on my phone.
A state-of-the-art real-time stream-data processing system and a comprehensive library of high-quality DSP blocks on my phone – that’s pretty cool. And once the toolchain is set up, it’s really easy to build SDR apps.
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.
