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.

  Thought the same thing. Would be super cool to project the night sky with procedurally generated cellestial objects, planes, spaceships, etc.

    I can't imagine it would take too much to pull that sort of real information, no? Like, what celestial objects are overhead, constellations, satellites, etc

  I thought the same thing! The plane being so low made it seem like an exaggerated computer-generated plane.

  I thought the same exact thing and I thought that I would love a sky projection on my ceiling

  Something like Sega Toys Homestar?

It's a planeatarium

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.

  I've got a Raspberry Pi 2b I've been using for probably close to a decade, with two SDRs hanging off it, pulling aircraft ADS-B locations and VHF radio transmissions out of the sky. It's a great application for this platform. ADS-B scanner averages about 25% CPU and the VHF airband receiver averages about 17% (uses hardware FFT).

    Such a fan of the lower power, fanless, larger/‘regular’ connectors old school rapi’s.

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 have used this on my tidbyt (now a Tronbyt) for years for this purpose... simple solution tied into my adsb system

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

Oof that looks like a loud place to live :O Happy to see it inspiring a project tho take care

Maybe this would be a better link: https://skylightceiling.com/

or the repo https://github.com/cpaczek/skylight

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

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.

  Do you remember the name? Would love to visit it

(To be clear, the "I" in the title is not me, the submitter - it's the title of the Reddit post).

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.

That is cool!

This is so awesome
