For the uninitiated, could someone briefly go over this? I find it extremely interesting and would like to pick it up as a hobby.
What kind of hardware you need to get started? How does it track the planes, do the planes broadcast their info periodically? Hooking this up to a web frontend using Google Maps or Google Earth sounds like a very fun weekend project.
