+# NOAA Automated capture using Raspberry PI
+Most of the code and setup stolen from:  [Instructables](https://www.instructables.com/id/Raspberry-Pi-NOAA-Weather-Satellite-Receiver/)
+### New Features!
+  - Nginx webserver to show images
+  - Timestamp and satellite name over every image
+  - WXToIMG configured to create several images (HVC,HVCT,MCIR, etc)
+
+### Manual work
+  - sudo apt-get install imagemagick nginx predict libusb-1.0 cmake
+  - Install [rtlsdr](https://github.com/keenerd/rtl-sdr.git) 
+
+### Important notes
+- I tried to run this on a Raspberry PI Zero Wifi, no luck. Seems like it's too much load for the CPU. Running on a Raspberry PI 2+ is ok.
+- Code was a bit updated on how it handles the UTC vs timezone times.
