I live in a Hurricane/Typhoon zone and wanted a way to watch storm live status without all the panicked commentary. I had an old Chromecast laying around and discovered that it is just a web browser so I built a simple html image bouncer that auto refreshes the latest satellite image of the storm, lets you crop in, etc. It works amazingly well for days of peaceful live coverage. An unexpected side perk is my kids can now tell the category (strength) of the storm based purely on the satellite image.
Turns out the code works for pretty much anything with a browser and any situation where there is an updating image at a static URL. So I’ve used it for a number of other things too. I put it all at https://github.com/antgiant/GOES-East-Big-Screen
