Introductory

A fantastic opportunity that my University provides are workshops that a UK-USA-Governmental Defense Contractor delivers.

At the end of every semester, these wonderful USA guys come in - and half of the fun is learning the cultural differences - lingo wise. They give us a week-long crash course, setting up vSphere VM's for us to all work on, secure and attack.

For example, a brief sample of topics that we've covered:

  • Static & Dynamic Malware Analysis
  • Intrusion Detection System implementation and utilization
  • Advanced Network Traffic Inspection
  • Powershell

It's all great fun really. Anyway! Back to the story, at the end of these workshops they run a 3/4 hour CTF. Of which I managed to win! Which is how I came to obtain a Raspberry Pi TFT 3.5" Touchscreen and various bits and bobs.


Installation

Well... Here it all is:

I even got little Heatsinks!!!

Not too much explaining to do for this part, so for the installation I'll throw the pictures into a gallery for your viewing pleasure!

Fixing

Notice how it's only a white screen? Well! As it turns out, you have to install drivers. The Git repository was listed on the instruction leaflet, and is specific to the model of screen.

I had to install the Armhf-variant of Debian Stretch for these drivers to install correctly.

Once following the "simple" compile instructions, lets restart!

Calibrating the Screen

Initially, the calibration was completely off, and was screwing with my head. Luckily there's a tool just for that.

But first, I had to install some dependencies.

sudo apt-get install libtool libx11-dev xinput autoconf libx11-dev libxi-dev x11proto-input-dev build-essentials

git clone https://github.com/tias/

cd xinput_calibrator

sudo chmod +x autogen.sh

./autogen.sh

make

sudo make install

Disabling Screen Blanking

sudo apt-get install x11-xserver-utils

sudo nano /etc/X11/Xsession.d/disableblank.sh

We need to input the following into the file:

xset s off      # don't activate screensaver
xset -dpms      # disable DPMS (Energy Star) features.
xset s noblank  # don't blank the video device

Make the file executable:

sudo chmod +x /etc/X11/Xsession.d/disableblank.sh

Add the disableblank.sh to the boot script

sudo nano /etc/xdg/lxsession/LXDE-pi/autostart

Append the file to the bottom of the boot script:

/etc/X11/Xsession.d/disableblank.sh

Installing a Virtual (Soft) Keyboard

Although it's touchscreen, you still require a keyboard to type. Let's fix that with the aid Elecrow-Keen (I'm just going to pretty much copy-paste code)

sudo apt-get update
sudo apt-get install libfakekey-dev libpng-dev libxft-dev autoconf libtool -y

git clone https://github.com/Elecrow-keen/matchbox-keyboard.git
cd matchbox-keyboard
chmod +x autogen.sh
sudo ./autogen.sh

After a few minutes of compilation, here we are:

sudo make
sudo make install
Again! Ghost really wasn't having the rotation ... but believe me it works!

Now I've just got to find something to use this for!
