    “Alexa, what plane is that?”

    We’ve all probably done it — gazed up at a passing jetliner and wondered where it was going and what adventures its passengers were embarked upon. While the latter is hard to answer, the former just got a bit easier: just ask Alexa what the plane is.

    Teaching Alexa to Spot Airplanes
    Fun with RTL-SDR and Amazon Echo Dot

    As an airplane fanatic, I’d often go to FlightRadar24.com to look up the different airplanes as they passed by, but after a while that became cumbersome.

    So, I taught Alexa to do the work for me!

    This was actually a pretty straightforward job. The first step was to make two new electronics purchases (not including my Echo Dot):

    Raspberry Pi (~$35)
    RTL-SDR USB Dongle (~$20)

    The dongle is essentially a radio receiver for your computer that can pick up most unencrypted radio broadcasts.

    By plugging the dongle into the raspberry pi (and placing by a window with an unobstructed view), and with the help of some open source software, the Pi can be turned into a cheap ADS-B decoder/server!

    In case there’s more than one airplane nearby, I use gpxpy to calculate the distance of each plane to my window and then choose the closest.

    Finally, I set up a public node js server on my raspeberry pi that pulls the airplane data and formats it into a good ol’ English sentence when requested. Then, I simply have Alexa make a request to the pi server when prompted and read back the result.

    If you’re not familiar with how Alexa skills work, you basically create a new skill on the Alexa Skills Kit dashboard, give that skill a name and various utterances that can invoke it (“what plane is that?”) and point it to an AWS Lambda function or similar service capable of processing an Alexa skills request. You don’t have to use AWS Lambda, but it’s definitely a quick and easy option for simple skills. Mine simply returns a basic Alexa skill response with the formatted airplane data from the pi server.

    Get eyes in the sky with your Raspberry Pi
    17 July 2017 on raspberrypi, flight tracking, docker, flightaware, radio, IoT, Raspberry PI

    Did you know that you can use your Raspberry Pi to get eyes in the sky? By tuning into radio signals emitted from planes up to 250 miles away from your location you can track flights and it only takes a few minutes and a cheap USB TV stick to get started.

    This guide will give you a brief introduction into flight tracking – looking at the software, hardware and most importantly the terminology and jargon you need to know. I’ll also show you how Docker and containers make a great combination for managing your software in IoT projects.

    Sites like FlightAware.com have been able to track 10s of thousands of aircraft by crowd-sourcing the task out to people all over the world equipped with their $35 Raspberry Pis and cheap USB TV tuners.

    You can keep the signals you pick up to yourself or contribute them to a real-time tracking site like FlightAware.com, FlightRadar24 and PlaneFinder.net – in return you get detailed metrics – RADAR readouts and other rewards.
