During the inspection of all the useless stuff in my appartment, waiting to be thrown into the trash, I found an old PIKO model train, which is almost my age.
It turned out, it worked ok, but needed a couple of tweaks to satisfy my laziness. First I attached a Raspberry PI with relay to the circuit and created a page on Raspberry's web server to start/stop the locomotive from my phone.
But I still didn't feel like a real Lokomotivführer, so I decided to implement a voice control. Since I don't know what's the proper way to command a German train, I use Russian words - Yuri Gagarin's catchphrase "poehali" (let's go) to start the locomotive and army command similar to "as you were" to stop it.
Sure, my layout is pretty inferior, compared to those of train modelling enthusiasts. Maybe that's a good thing that I don't have too much free space at my home, because I've suddenly found another perfect way for me to waste a lot of money.
PS: Here's a little POV-video from a GoPro camera, which I've attached to the wagon.
