Do it yourself, Cheap ADS-B, with Raspberry Pi

[n85ae]

Quite interesting thread over here at the Naviator forum, if anybody's
into computer stuff, etc. This is actually a pretty simple device to build,
and for probably under $100 you can get ADS-B IN for about an afternoon
projects worth of fooling around. It's not totally robust yet, but I bet with
a few more weeks time it will be.

There is a similar project for ADS-B in on the EAA Website, here:

Two documents for the same project basically, Raspberry Pi, with Stratux
installed.

Can't wait for somebody to come out with the FAA legal Raspberry Pi
$100 ADS-B "Out" version.

I built one. I have the GPS and AHRS chip wired in to mine. Not that I needed the GPS and AHRS but I like to tinker. It works really well.

Lot's of different links, and docs out there. Which did you follow for the AHRS/GPS? Could you post the links?

Thanks!

I started with the simplest unit, ADS-B UAT978. I had just under $100 in it. Then added the second dongle for the 1090es frequency. The 1090es isn't really needed for flight below 18,000 ft, plus it takes more power to run it with the second dongle. Supposedly after the end of this year, the FAA will transmit all 1090es information over the 978 UAT frequency anyway. I then added the AHRS chip. I'll add the links I found most useful below. You might search around and find the components cheaper, this is just a easy reference list.
The battery pack listed below is ok if you are running a single dongle but it doesn't provide enough power with 2 dongles. You can search the reddit forums for better packs. I can also run it off of usb power in the plane as long as the usb output is at least 2.4 amps. I'll list the cig adapter I use.

This article is an easy explanation.

That should get you started. If you need links to wiring, etc. let me know.
All of the information is at the following 3 links.
