This little gadget plots the location of aircraft on a map, so I can check out what's flying over my house. It uses a public ADSB API, and Leaflet for the maps.
Unfortunately, it turns out most of the aircraft I'm interested in do not carry an ADSB tracker, so it's not very useful.
I build and fly radio controlled aircraft. I wrote a tool to grab the local weather forecast and display it in an easily-scannable format.
I needed a minimal backend to hide my API key and do some data manipulation but didn't want to run a server. I'd been looking for a good excuse try out Firebase, and this was it.
