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

    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.

    Thanks. I've got all those links already, and the parts ordered. However that's
    a good consolidated list for people to use tha you posted.

    The part I was having a hard time figuring out was the AHRS module itself. I see
    you posted the source for the part link, do you have any links for setting
    it up?

    It comes with a usb cable but the best way is to wire it to the GPIO connection.
    Wiring is as follows:

    Left value is chip circuit -> Right value is GPIO pin location

    Power:
    VDD -> PIN 02
    GND -> PIN 06

    AHARS Data:
    SDA1 -> PIN 03
    SCL1 -> PIN 05

    GPS Data:
    TXD -> PIN 10
    RXD -> PIN 08

    Here is the link to the Raspberry Pi GPIO pinout
    http://pi.gadgetoid.com/pinout

    The software download takes care of any setup. Just wire in the chip, mount it however you want and off you go. There are several people offering plans to download for 3d printing cases. Just search through the Reddit forums under Stratux. For now, I have mounted my AHRS/Gps chip to the top of the case that comes with the Raspberry.

    So once you wire in the AHRS, then the data out from it automagically gets's
    into the datastream along with the weather and traffic info?

    I poked around in the Raspbian image they provided, and figured out more
    or less how they do it. I'm not that inclined to try doing any programming in
    there but it seems straightforward. I'm still not quite sure how they get
    the output from the /usr/bin/stratux script, which is using 'screen' out
    port 4000 udp, but I guess it's just enough to know it does it.

    I also understand they haven't figured out how to shut it down yet,
    other than just hope the filesystem survives the power cycling, or are they just
    bringing it up readonly?

    ****ed at Amazon, they shipped two day prime, but elected to use USPS
    for final delivery, which means my two day Prime is more likely four day ...
    So other than looking at source code, and poking in the Raspbian image
    I can't play with it yet. Grr....

    It all comes through in the same stream. I added WebSSH app to my iPad and added a shutdown option through it.
