I recently gave a presentation on Software Defined Radio (SDR) at my hackerspace in Chicago, Pumping Station: One. I’ve attached the slides to this blog post for reference. After the talk, someone told me they had seen a program that maps out airplanes flying in one’s area based on data received via Automatic dependent surveillance-broadcast (ADS-B) on 1090 MHz. After a search, I found dump1090 which works with cheap DVB-T USB sticks with certain Realtek chipsets thanks to the rtl-sdr library….
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
