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.

Curious to know how you manage to concentrate during waking hours on work and how you sleep peacefully?

There's a lot of trains in Switzerland so there's a lot of apartments by tracks. For the most part, the apartments are just built well.

Plus, the trains and tracks are very well maintained, so they create a lot less noise than you may be used to.
