The Pi became part of my essential hardware for flying with the Stratux project. You could plug an RTL-SDR into a Pi, add a wifi adapter, and have it broadcast weather and other ADS-B equipped aircraft to some of the flying tools. With Avare, ForeFlight, FlyQ (most of the other EFB software out there except Garmin) it will overlay the information on the moving map.
How do you feel about the reliability of this setup? I currently use a Dual GPS for (VFR) navigation and am wanting to get ADS-B in, but I want to reduce the risk of distraction caused by a failing receiver (or backup AHRS) in flight. Has the Stratux proven as reliable as more integrated solutions like a Sentry Mini?
I'm usually my own worst enemy of messing with a working image, so if it was broken, it was usually my own fault.
I use the same Bluetooth GPS receiver with Avare on an Android tablet in conjunction with a Pi and a pair of antennas. The stock images are more or less fool proof if you pick USB radio receivers that are on the supported list. I had wired a GPS to it too at one point - but had an incident with a model airplane and a lake, so continue to use the external Dual. I've never gotten around to putting it in a one unit case.. basically end up tossing it in the back seat dangling everywhere.
I replaced our Stratus (guess where the project name originated from) with the homemade one. On the recommended hardware, it is solid. I was also able to (usually) make it work on non-certified (if you can call this hand rolled combination certifiable) hardware like the pi zero. Hit and miss with the newer stuff. Need to pick up one of the newer pis to help out with the porting. By far, my biggest issue was making sure the battery pack was charged.
I built a Stratux and used it with Foreflight. Honestly, the reliability wasn't great. The dump1090 process would randomly disconnect, generating nuisance alarms from my tablet - usually in busy airspace. It also had trouble picking up some ground stations.
I switched to a Garmin GDL-52 instead. Reliability has since been rock solid. Received signal strength from ground stations are an order of magnitude better.

is the project I'm most familiar with. If you just want to use the hardware it is a very easy paint by number setup.

If you wanted to jump into a GoLang project, this is a really interesting codebase.
