Maybe you've created your own AR program for wearables that shows the definition of a word when you highlight it IRL, or you've built a personal calendar app for your family to display on a monitor in the kitchen. Whatever it is, I'd love to hear it.

I have a rail line right under my apartment, so I built a small computer vision app running on a Rasperry Pi which records each train passing, and tries to stitch an image of it.

It has a frontend at https://trains.jo-m.ch/.

Edit: it's currently raining and the rain drops are disturbing the images a bit.

Really cool. They look like model trains! :-)

Yeah! I've never seen trains so clean and modern looking in my life. They look like they came out of a futuristic toy set.

That's Europe for you. Usable train infra is actually a thing.

It somewhat works but let's not exaggerate how well it works.
