I should clarify that I’m mostly guessing on your bill of materials. There are only a few obvious choices for this project.
I got all the camera gear on ebay, which was lucky.
I figure since it is all based on ADS-B data, there isn't anything too crazy about making it public. I am also still trying to figure out if it is actually useful for anything... besides getting unlimited plane photos!
The only non-public information you're making available is the approximate location of your house!
It's a very high end approach to planespotting though. People used to just tick off serial numbers in books :D
