Raspberry Pi Wearable Timelapse Camera

Read about the project here: http://manoj.ninja

Setup

Install Raspbian Jessie Lite onto your Raspberry Pi and run:

$ sudo -s
$ apt-get update
$ apt-get install hostapd dnsmasq git python-pip apache2 python-serial -y
$ apt-get upgrade -y
$ git clone https://github.com/Manoj-nathwani/raspberry-pi-timelapse-camera.git

Setup Access Point

Edit the iface wlan0 part of your /etc/network/interfaces file to look like:

iface wlan0 inet static
    address 10.0.0.1
    netmask 255.255.255.0

At the bottom of /etc/dhcpcd.conf add:

interface wlan0  
    static ip_address=172.24.1.1/24

Edit the DAEMON_CONF part of your /etc/default/hostapd file to look like:

DAEMON_CONF="/etc/hostapd/hostapd.conf"

Make a /etc/hostapd/hostapd.conf file with:

interface=wlan0
driver=nl80211
ssid=a_potato
channel=1

Make a /etc/dnsmasq.conf file with:

interface=wlan0
dhcp-range=10.0.0.2,10.0.0.5,255.255.255.0,12h

Reboot your device and an open access point called a_potato will automatically run! You should be able to see it and connect to it from another device, however it may give you a warning about not having an internet connection.

Mount USB drive (to store the images)

Run lsblk to see where your USB stick is

$ sudo mkdir /media/usb
$ sudo nano /etc/fstab

Add /dev/sda1 /media/usb to the bottom of the file

Setup linkit-one-code

Deploy the LinkitOne application through the regular Arduino upload method.

Setup raspberry-pi-server

$ cd /home/pi/raspberry-pi-timelapse-camera/raspberry-pi-server
$ pip install -r requirments.txt
$ python app.py

Setup raspberry-pi-code

$ cd /home/pi/raspberry-pi-timelapse-camera/raspberry-pi-code
$ pip install -r requirments.txt
$ python app.py

Setup crontab

Edit your crontab by by running crontab -e and adding the following to the end of the file:

# run flask web server @ 10.0.0.1:5000
@reboot python /home/pi/raspberry-pi-timelapse-camera/raspberry-pi-server/app.py

# take a picture every 1 min
* * * * * /home/pi/raspberry-pi-timelapse-camera/raspberry-pi-code/app.py

Setup RTC

apt-get install i2c-tools

Edit /boot/config.txt and append:

device_tree_param=i2c_arm=on

Edit /boot/cmdline.txt and append:

bcm2708.vc_i2c_override=1

Edit /etc/modules-load.d/raspberrypi.conf and append:

i2c-bcm2708
i2c-dev
