Programming

First download the latest Raspbian Jessie from here https://www.raspberrypi.org/downloads/raspbian/, and follow the installation guide link on that page

On The Raspberry Pi Zero in Terminal and type these commands to install the
RTL8723BU Wifi+Bluetooth 4.0 module (should take about 1 hour to compile)

First Lets install the Wifi drivers

pi@raspberrypi:~ $ sudo apt-get install raspberrypi-kernel-headers
pi@raspberrypi:~ $ git clone https://github.com/lwfinger/rtl8723bu.git
ls
cd rt*
sudo make
sudo make install
sudo insmod 8723bu.ko
ifconfig
sudo reboot

Next we are going to install the Bluetooth 4.0 Drivers

git clone https://github.com/lwfinger/rtl8723au_bt.git
cd rtl8723au_bt
git checkout -b kernel origin/kernel
git branch
git pull
sudo make
sudo make install

sudo reboot

Check if everything is working perfectly with the wifi + bluetooth (connect multiple bluetooth devices).

*Type this command, we are going to edit the screen dimension output since i noticed some overscan space. Originally the video glasses is advertised 240x360 but its actually 720x480 after i noticed some empty overscan space. We are going to use some overides in the /boot/config.txt.

pi@raspberrypi:~ $ sudo nano /boot/config.txt

now just uncomment "disable_overscan=1" and set framebuffer_width=720
framebuffer_height=480

"#" uncomment this if your display has a black border of unused pixels visible
"#" and your display can output without overscan
disable_overscan=1

"#" uncomment to force a console size. By default it will be display's size minus
"#" overscan.
framebuffer_width=720
framebuffer_height=480

CTRL+x

Y
press enter to save

Next install cloudsight and unirest.

sudo pip install cloudsight
sudo pip install unirest

pi@raspberrypi:~ $ sudo pip install cloudsight
pi@raspberrypi:~ $ sudo pip install unirest

Create 3 folders in home/pi/

FacialRecogntion
ImageOCR
ImageRecogntion

You can either chmod 777 via command line or right click the FacialRecogntion,ImageOCR,and
ImageRecogntion folders and make sure Anyone is selected for all 3 sections.

Download the full.py to the Pictures folder (its included in the Thingfiles)

Make sure the full.py permissions is set 777 or the 3 sections in the Access control set to anyone

Finally in terminal we will acces crontab -e .This is a file which contains the schedule of cron entries to be run and at specified times. In this case we want to run the file at every reboot.

pi@raspberrypi:~ $ crontab -e

@reboot sleep 10; XAUTHORITY=/home/user/.Xauthority
@reboot sleep 10; export DISPLAY=:0
@reboot sleep 10; export DISPLAY=:0.0 && python /home/pi/Pictures/full.py &

Assembly

Assembly is usually the easy parts.

Start by threading the smd wired through the buttonbridge

Next solder the ends of the smd buttons to the Pi Zero, and connect the camera cable to the Pi Zero

Slide the Pi Zero through the PiHolder, with curved tweezers carefully guide the jst connecter and the camera cable through Buttonholder piece and the front bridge piece.

Place the camera in the eyepiece.

Use a little piece of tape to hold the magifyholder to the eye lens
