With all the satellites in space, we are almost always under observation. wouldn't it be fun if we could know when we are being observed?
Here is a quick hack I developed over the weekend using te beaglebone! The beaglenone downloads TLE values from NORAD and PyEphem to calculate the current position of the ISS and Tiangong 1, and Light up whenever one of them passes ovr me!
Now I can keep an eye on the eye in the sky! :P check out the video below:
