This fantastic project by Pavel Shved keeps him up to date on San Francisco’s weather and bus schedules at home, in SF Muni style!
San Francisco “Muni” public transportation vehicles, like those of many other modern big cities, are equipped with real-time GPS trackers, and publish location data on the internet. My smartphone has QuickMuni app installed, so I could easily be checking it. I would pick up my phone, unlock it, wait for all the lags Adnroid greets me with, wait while the app downloads the upcoming train times, and repeat this every five minutes. This would be implausible. If only I had something like a wall clock so that it constantly displays upcoming train time predictions…
One morning I located the item I wanted in the wild. Actually, I’ve been seeing it every day, but was not realizing that it would solve my problem.
That is it! I can mount a similar sign on my wall, drive it with something like Raspberry Pi or even my desktop PC, and write some software to download, process, and display the train arrival times! I can even teach it to show weather forecast to quickly see if I need to take an umbrella.
