Love my Stratux! Been using it for over a year. It's awesome and has been a big help with weather data. I used Stratux just this afternoon. Saw traffic around me and got weather at destination. I don't x-c without it anymore.
The external GPS is not necessary if your iPad has built in GPS unless you don't get good reception on the iPad in your aircraft. it works great in mine. Make sure you install the sticky copper strip inside the case as directed as that is the antenna ground plane which greatly helps. You might want to hit the inside top of the case with bright white paint or just stick a piece of white paper in there to reflect sunlight away to reduce heat on the board. Usr a quality USB battery. I recommend Anker. often these Stratux kits recommend cheapo obscure brand batteries. Also use a quality USB cable and no longer than absolutely necessary. My first Stratux setup used a long cheap cable which caused too much voltage drop across the cable so the computer would crash.
I wrote the UAT demodulator that was subsumed into dump978 and used by Stratux later. It really grinds my gears that the performance of RTL-SDR is not sufficient to receive UAT, generally speaking. So, instead of actually demodulating, I used sampling to self-clock and then just looked at the phase angle between 2 samples. If the sampling hit the bits right, the result was a packet. If not -- garbage. So, at best of times, Stratux only receives half of the UAT packets and drops half. This makes weather delivered slower than possible with a proper receiver. I really hope that this is what $600 buys you with a commercial UAT receiver.
I wouldn't say that if other aircraft have ADSB-out, then they most likely see you, is a valid statement. Part of a club that recently upgraded our transponders. Only a handful have a Foreflight subscription to even use it. Since its a proprietary Stratus signal, I can't get the data on an android tablet. Which is why I'm watching this video :)
This. Assuming other aircraft are going to corrective action because they have "ads-b out" falls into complacency human factor. You don't know if its a student going into his first cross country solo overloaded with information in one of those expensive flight school Cessna fleets, or somebody with the autopilot on trying to check whether he can pick up a bar of 4G signal so he can load up facebook on his smartphone. Always be aware of your surroundings.
How does the battery shut off? I hold the battery power button until the red and green light go out, but once releasing the battery button the red and green lights go on again. Is there a certain number of seconds required to power down the battery pack? thx.
Aviation weather is a little different and not quite what you're used to seeing in typical apps and on your local news stations. Not that it won't be useful, it obviously is for us. There aren't predictions like "40% chance of". A forcast will simply say "rain, thunderstorm, snow" and so on. No "chance of" per say. They also generally don't forecast much passed 12-18 hours, so you're not going to get things like a 5-day forecast off what gets aired. It's a very rudementary coded text that with a little google isn't hard to decipher. So basically what I am saying, for "ground" use, it would be extremely impractical with no real benefit to you that's worth shelling out any kind of money like this for. You get live conditions and such, but you can also get that from any free, or really cheap app.
No, checkout the skybeacon for the simplest/wallet friendly way to comply. Depending on your plane /typical cruise altitude you might want a dual band solution with in and out. There are lots of caveats to equipage and John noted one of them. If you aren't flying in or above B/C you might not need it at all.
great project, but I think the AHRS is worth the extra $ for a commercial unit. particularly if you are only flying with a vac system. could absolutely save your bacon. of course you could also go pay $5-10k for a panel mount..... yeah right....

Which branch of dump978 did you work on?
Original code is here: github.com/zaitcev/ruat But it only has historic interest. Even mutability/dump978 is vastly better.
github.com/mutability/dump978/blob/289eff664d0dc3b955098d02da705bd2265db918/dump978.c#L283-L307
I already have ADS-B in & out on my aorplane.. but I still want to build this.. because of reasons.. ha
I don't even have a plane and I still want to build this haha :)

It's merely supplemental to visual avoidance and/or ATC separation.
Wish Stratux would have an ADSB in AND out!
I don't even own a plane, and I want to build one.

I built one and I am getting ghost signal from my own airplane giving me a traffic alert some times?
That happens sometimes on even the best (Dynon and Garmin) built-in/OEM systems.
A TH-cam guy just solved the ghost problem. It’s the ForeFlight setting.
Can we use a Rasberry Pi4 model B?
Is there a way to just fit a LCD screen directly on it? I need to keep weight right down.
Would this be any good for a non pilot to see local weather from the ground?

Will this meet the 2020 requirements for ADS-B?

Total price how much sir

You can add an AHARs chip for something like 40$
Not even a weekend project. More like a 1 hour project. Lol
where can you buy all the parts? can you get it in a kit?
Does this fulfill the requirements for 2020?
I'm not an expert, but my guess is "no". This unit is an ADS-B IN. By 2020, you need an ADS-B OUT.
No. This is ADS-B in only, not out.
That's my weekend from hell. God bless the tech geeks! You make the world better! I'll stick with my day job. DIY avionics is NOT a thing! Lol!
This does not even involve soldering.... This is putting Lego blocks together.
