Messing around with SDR is a really fun little hobby. There's something very satisfying about picking up signals that are just floating around waiting to be seen.
I briefly tried writing an SDR tuner in JavaScript a while back but there was a bug somewhere between Chrome and my SDR dongle that meant it failed whenever you tried to tune to a different frequency. I might pick it back up and see if it's possible now.
If you're interested in near-realtime weather images without having to fiddle with SDR, NASA collate images from loads of different satellites at https://worldview.earthdata.nasa.gov/ https://worldview.earthdata.nasa.gov/ and so do EUMETSAT at https://view.eumetsat.int/productviewer?v=default# https://view.eumetsat.int/productviewer?v=default#
I used the EUMETSAT data to build this service which provides 3-hourly cloud maps for the whole Earth, which are surprisingly difficult to find: https://github.com/matteason/live-cloud-maps https://github.com/matteason/live-cloud-maps
- raffraffraff 3y agoI was expecting the NASA link to be a somewhat usable experience but it's... perhaps not for someone who just wants a weather prediction. The map is blank unless you add some layers, and I just spent "too long" failing to find anything useful. There are layers with data from 1987. maybe I need to use this on a desktop browser.

- somishere 3y agoThis is an amazing resource. Thank you.
- NKosmatos 3y agoI remember seeing your page somewhere, but it got lost between all the opened tabs and I didn't bookmark it. Now that I've rediscovered it, and found the creator, I can say thanks mate :-)
- matteason 3y agoHa, thanks! You probably saw it when I submitted to Show HN. Hope it's useful!
