I built a ceiling projection mapping of the planes flying over my house old.reddit.com

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

Something like Sega Toys Homestar?

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

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

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