SETUP AND ACCESS:

Setup WIFI
SSH
VNC:
- Currently Running stuff:
  - startx
  - x11vnc -display :0 -q
- New Desktop: vncserver :1
Video Out:

    /boot/config.txt settings for edge to edge beauty:
    sdtv_mode=0 #for NTSC
    sdtv_aspect=3 #for 16:9
    framebuffer_width=480
    framebuffer_height=272
    disable_overscan=1 #non-intuitive but the overscan_scale does the work
    overscan_scale=1 #currently undocumented but works
    overscan_left=16
    overscan_right=16
    overscan_top=8

GPIO:

GPIO Setup:
- WiringPi:
  - git clone git://git.drogon.net/wiringPi
  - cd wiringPi
  - ./build
  - Python Wrappers:
    - sudo apt-get install python-dev
    - sudo apt-get install python-setuptools
    - git clone https://github.com/Gadgetoid/WiringPi2-Python.git
    - cd WiringPi2-Python
    - sudo python setup.py install
- ADC
- setup:
  - wire to pin and ground
  - Setup global mode:
    - GPIO.setmode(GPIO.BCM)
  - Setup Specific pin:
    - GPIO.setup(14, GPIO.IN, GPIO.PUD_UP)

Screen Blanking:

sudo nano /etc/kbd/config
- change: BLANK_TIME=30
- to: BLANK_TIME=0
sudo nano /etc/X11/xinit/xinitrc
- after first line, add:
  - xset s off
  - xset -dpms
  - xset s noblank
`sudo nano /etc/lightdm/lightdm.conf
- [SeatDefaults]
- xserver-command=X -s 0 -dpms
`sudo nano /etc/xdg/lxsession/LXDE/autostart
- # @xscreensaver -no-splash <-make it commmented out
  - add:
    - @xset s off
    - @xset -dpms
    - @xset s noblank

Post XWindows Start:
- EDIT: /etc/xdg/lxsession/LXDE-pi/autostart
  - at end add: @/usr/bin/python /home/pi/...<file.py>
- To run as superuser:
  - EDIT: /etc/xdg/lxsession/LXDE-pi/autostart
    - at end add: @/usr/bin/sudo /home/pi/...<file.py>
  - EDIT: <file.py>
    - first line add: #!/usr/bin/env python
  - In terminal:
    - sudo chmod +x <file.py>

Making images of SD card

Here is a great guide to pulling the image and shrinking it
