Love this flight tracker. John was extremely helpful in getting it set up -- I had to 'forget' my home wifi network so it would stop overriding the raspberrypi network. Once we figured that out, it's been working perfectly. I'm still experimenting with the boundaries that I want, but it's awesome to glance at it whenever I hear a plane overhead, and see what's up there. I especially like that it shows how fast the plane is traveling, as well. Also, it's a nice feature that it just turns into a retro clock when no planes are overhead. The display and solid wood box are very well made. Definitely recommend this!
