+# Raspberry PI
+I tried to use a Raspberry PI Zero Wifi, but seems like the lack of power makes bananas. Got several issues when recording the audio stream (blank audio, corrupted wav files, etc) as well as wxmap errors when trying to do the overlay. A Raspberry PI 2+ works great, no issues at all.
+
+# Power
+I also experimented several issues with power supply when using cheap mobile phone USB chargers
+```
+kern  :crit  : [ 1701.464833 <    2.116656>] Under-voltage detected! (0x00050005)
+kern  :info  : [ 1707.668180 <    6.203347>] Voltage normalised (0x00000000)
+```
+Use a 2+ amps power supply, as the SDR dongle is a power demand device.
+
+# SD Card
+I'm using a cheap (and probably fake) 16GB Kingston SD card, no reported issues.
+
+# SDR Dongle and reception
+I'm using a rtl-sdr.com usb dongle, works great. I'm also using a FM trap (88-108Mhz) to avoid FM broadcast signals.
+
+# Antenna
+I'm using a homemade QFH antenna. Refer to [Jcoppens QFH antenna website](http://jcoppens.com/ant/qfh/index.en.php) for building and calculations

+  - WXToIMG configured to create several images (HVC,HVCT,MCIR, etc) based on sun elevation
   - Pictures are posted to Twitter. See more at [argentinasat twitter account](https://twitter.com/argentinasat).
-  - [Wiki](https://github.com/reynico/raspberry-noaa/wiki) is updated!
-  - Audio files are stored on a RAMFS partition. Happen to had some glitches on image reception
 
 ### Install
-There's an [install.sh](install.sh) script that does everything at once. If in doubt, see the [Wiki's install and config page](https://github.com/reynico/raspberry-noaa/wiki/Initial-installation-and-configuration).

-### 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. See [Wiki's hardware notes page](https://github.com/reynico/raspberry-noaa/wiki/Hardware-notes).
-  - Code was a bit updated on how it handles the UTC vs timezone times.
-
-### To do
-  - [Calculate sun elevation for each satellite pass to decide image enhancement](https://github.com/reynico/raspberry-noaa/commit/e21abc616b289a768129006863e48f0c815814b9) done.
+### Hardware setup
+Raspberry-noaa runs on Raspberry PI 2 and up. See the [hardware notes](HARDWARE.md)
