Building and Flying with Stratux ADS-B In, part 2

Over a year ago I wrote about my initial experiences building and testing out the open-source Stratux ADS-B In receiver. I've gotten more involved with the project since then, testing out new hardware and changing my existing build. I've also had the chance to use some competing hardware!

TL;DR: build yourself this $140 Stratux

Cost Description
$ 37.20 Raspberry Pi 3 to run the whole show
$ 14.99 8GB SD card with Stratux installed
$ 39.99 Tuned antennas and radios for receiving weather and two traffic channels
$ 14.99 GPS receiver for integrated position data
$ 14.99 ABS plastic case, designed by /u/helno of Reddit
$ 12.99 Anker 24W 12VDC charger can run both an iPad and your Stratux
$ 6.99 Anker 10' USB cable lets you position the Stratux anywhere in the cockpit
$142.14 total price

If you're a pilot without existing access to ADS-B In weather and traffic, build this list. The same results cost $233 a year ago, and the software has matured while the hardware has improved. For under $150, you can get dual-band ADS-B In traffic and weather with WAAS position data. It's fantastic.

Building (and flying with) Stratux homebuilt ADS-B In

UPDATE: new writeup 17 July 2017, with a new $140 parts list

I first heard about the Stratux project a few months back, in a subreddit that described how to build your own ADS-B In receiver for under $120. It uses software-defined radios to pick up ADS-B data, then processes it using open-source software. As a pilot who's dabbled with the idea of plunking down around $1000 on the Stratus 2S, this was a pretty attractive idea: less than $200 for traffic and weather on my iPad? Heck, I could build a receiver and order a new iPad for less than the list price of the Stratus.

I took the plunge, ordered the parts, and tried it out.

The verdict? It works brilliantly.
