I built a ceiling projection mapping of the planes flying over my house

Wow so cool! I had daydreamed about doing something similar with e-ink display on my wall so I could see details about whatever plane I'm hearing.. but this blows that out of the water.

I'm sensing "The Conversation" levels of paranoia and it is beautiful.

It's a planeatarium

Maybe this would be a better link: https://skylightceiling.com/ or the repo https://github.com/cpaczek/skylight

I bought several 3b+ Raspberries a really long time ago and this seems like the perfect simple&breathtaking project for such ancient hardware. Who needs a fourth PiHole on their local network?! "Fortunately" I live directly beneath CHA's main landingstrip, so lots of regular data available. Fortunately, I am not in the main takeoff path because that would be much worse .

This is so awesome

The repo subtitle is `Project the aircraft passing overhead onto your ceiling, in real time — an X-ray through the roof.` The demo video starts outside pointing at a cloudy sky with an airplane passing overhead. My mind, seeded with the word "x-ray", thought the outside shot was the video projection on his ceiling. I thought his rain gutters were crown molding, and when the camera man runs inside, I thought he was running outside to show the real life airplane. The actual projection is neat, but how fun would it be to have an x-ray projection of the night sky.

Not too many things make my jaw literally drop, but this did. This is magnificent!

I expect to have trouble falling asleep just vicariously relating to the noise level there. Awesome project though.

Random aside: there’s a restaurant in San Diego on the SAN flight path with a split flap display over the bar. Every time a flight passes over it updates to show flight number and departure airport. It’s quite neat.

The fact that I saw this on X first is concerning, greatjob btw

Would have loved a post on working out the geometry of the projection, especially if it accounted for transitions of ceiling to wall. That would be fun. The surface through which one is projecting is a flat rectangle. Had it been a hemispherical dome one wouldn't have had to do anything special for the transitions.
