   Material Required

   Raspberry Pi Zero 2 W with Pre-soldered Headers

   264×176, 2.7inch E-Ink display HAT for Raspberry Pi

   MicroSD Card – 32 GB – Class 10 – BLANK

   Raspberry Pi 12.5W Power Supply, US, White

   HOVSTA – Frame, birch effect, 13×18 cm

   Golden State Art, Pack of 25 5×7 Multicolor Uncut Mat Boards – Great for Photos, Pictures, Frames – Acid-Free, White-Core

   The code used in making this weather station is the modified version of the below project.

   Weather Station with ePaper and Raspberry Pi, in that project a color 264×176, 2.7inch E-Ink display HAT for Raspberry Pi, three-color is used. I am using the BW model of the E-Ink display and have modified the code to use black and white color.

   Preparing the Hardware and Software

   Install the Raspberry Pi OS on the SD card.

   Layer 1: make the mat board, do some artwork on the white color mat, and cut the frame to fit the display.

   The below design was done by Fathima Farha. Thank you.

   

   Layer 2: Cut the frame to fit the display.

   

   Layer 3 – Cut the frame to fit the display.

   

   Layer 4: Cut the frame to fit the display.

   

   Layer 5: On The back panel of the frame, make a square so that the raspberry pi zero 2 fits accordingly on the display

   

   Now stack the frame as given in the below images

   

   

   

   

   

   

   

   Power up the Pi – the once the program is started, the weather station looks like below.

   We will learn how to Build and install CubicSDR (A Cross-Platform Software-Defined Radio Application) from source on Ubuntu 22.04.2 running on Raspberry Pi 4.

   Install Basic build support:

   $ sudo apt-get install git build-essential automake cmake

   Install Base Dependencies:

   $ sudo apt-get install libpulse-dev libgtk-3-dev

   Install OpenGL Dependencies

   $ sudo apt-get install freeglut3 freeglut3-dev

   Build and install SoapySDR

   $ mkdir ~/Works
   $ cd ~/Works
   $ sudo rm -rf SoapySDR
   $ git clone https://github.com/pothosware/SoapySDR.git
   $ cd SoapySDR
   $ mkdir build
   $ cd build
   $ cmake ..
   $ make
   $ sudo make install
   $ sudo ldconfig

   Download and Install Driver for SDRPlay RSP devices:

   From https://www.sdrplay.com/downloads/ – Download ARM Ubuntu specific API & Driver – 64 bit.

   Make the file executable:
   $ sudo chmod 755 ./SDRplay_RSP_API-ARM64-3.07.1.run

   Run the file:
   $ ./SDRplay_RSP_API-ARM64-3.07.1.run

   Build and Install SoapySDRPlay:

   $ cd ~/Works
   $ sudo rm -rf SoapySDRPlay
   $ git clone https://github.com/SDRPlay/SoapySDRPlay.git
   $ cd SoapySDRPlay
   $ mkdir build
   $ cd build
   $ cmake ..
   $ make
   $ sudo make install
   $ sudo ldconfig

   Okay, now let us Check the SoapySDR installation:

   SoapySDRUtil –info

   SoapySDRUtil –probe=”driver=sdrplay”

   Build and Install Hamlib libraries:

   Download hamlib-3.3.tar.gz from: https://sourceforge.net/projects/hamlib/files/hamlib/3.3/ and
   copy to ~/Works

   $ cd ~/Works
   $ sudo apt remove libhamlib2
   $ tar -zxvf hamlib-3.3.tar.gz
   $ cd hamlib-3.3
   $ ./configure –prefix=/usr/local –enable-static
   $ make
   $ sudo make install
   $ sudo ldconfig

   Build and install liquid-dsp:

   $ cd ~/Works
   $ git clone https://github.com/jgaeddert/liquid-dsp
   $ cd liquid-dsp
   $ ./bootstrap.sh
   $ CFLAGS=”-march=native -O3″ ./configure –enable-fftoverride
   $ make
   $ sudo make install
   $ sudo ldconfig

   Build static wxWidgets:

   $ cd ~/Works
   $ wget
   https://github.com/wxWidgets/wxWidgets/releases/download/v3.1.3/wx
   Widgets-3.1.3.tar.bz2
   $ tar -xvjf wxWidgets-3.1.3.tar.bz2

3. ECSA : My Thoughts and concerns

   IT Security Analyst

   The EC-Council Security Analyst course was a very big step towards in my career. This experience gave me a wider approach towards system and analytical security and refined my information security skills. The ECSA course provides for a better subject matter understanding both theoretically and practically.

   The course through its duration exposed me to different security methods that need to be dealt with on a daily basis and taught me necessary tools and techniques to analyze the very same. My knowledge of eliminating system vulnerabilities increased and I gained skills required to test and mitigate them.

   I need to mention that the most interesting experience or aspect of the ECSA course were the iLabs, since I had had never had hands-on training with other certifications than ECSA. After attending the ECSA program I believe my skills set as an IT Security Professional have increased and my market value has risen substantially.

   I need to mention one important person name this time Mr. Shafeeque Kunnikkal, my tutor. With his help and support (even after course completion) was commendable. With his proper guidance throughout the course I also managed to successfully completed the course within the stipulated time-frame mentioned.

   I would like to thanks “EC-Council for introducing the Security Certifications Like ECSA and LPT and to My tutor Mr. Shafeeque Kunnikkal for all the help I’ve received to build a security professional Career”.
