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 $140 Stratux
|$ 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|
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.
