I never mentioned here that I built a webpage with a map that shows where all the scheduled passenger NJ Transit trains are.

I take NJ Transit regularly to go to work and you could say it's less than 100% reliable, so this map helps me figure out how delayed my train is and whether the system is completely screwed up.

And it's also impressive to see over 100 trains at once during peak hours.

You look like cool people who will appreciate what I just uploaded.

I built a web-based RTL-SDR app. It works like your usual SDR++ or Gqrx, but entirely in your browser! With waterfalls and everything!

So dig up your old RTL-SDR stick and go to https://radio.ea1iti.es

And it works on your Android phone!
