Ask HN: Personal C&C software/hardware?

I will be moving into a new property in the coming months and I'm daydreaming about what I could do with one of the rooms. I'd like to have some sort of personal "Command & Control" center, where I'd be able to stream international TV stations, weather patterns[1], aggregate news from online sources of my choosing, a projection of the solar system with Earth's position relative to the sun available in real time, etc. Maybe even passive radar using AM/FM, or some SDR listening on whatever's going on in my area. General geeky stuff.

Do any of you have such a setup? Are there software projects related to this I should be aware of?
