Repeatable instructions to get your budgie-cam up and running!
Shopping List: $90
- Raspberry Pi 3 - Model B - ARMv8 with 1G RAM: $35
- 5V 2.4A Switching Power Supply w/ 20AWG 6' MicroUSB Cable: $8
- Raspberry Pi Camera Board v2 - 8 Megapixels: $30
- 8GB SD Card with Raspbian Jessie Operating System: $12
- Adjustable Pi Camera Mount: $5
- Raspberry Pi Model B+ / Pi 2 / Pi 3 Case Lid - Yellow: $3
- Pi Model B+ / Pi 2 / Pi 3 Case Base - Green: $5
- Optional but recommended: Flex Cable for Raspberry Pi Camera or Display - 300mm / 12": $2
- Optional if you want to record audio: USB Microphone: $6
- Depending on your cage and home setup, you may want to choose a different length of flex cable for the Raspberry Pi camera. Note that the longer your cable, the more likely you are to have degraded picture quality. Shorter cables are better here. It's a tradeoff between ease of mounting and picture quality.
- Not included: a way to mount the Pi to your cage or fasten the camera to the cage. I use Scotch mini velcro squares to mount both my Pi and my Camera to the cage and they work very well, but get creative!
- The USB Microphone I bought didn't fit very well into any of the USB ports I had and I wasn't sure it was in correctly, but it does record audio.
- For best results and maximum style, choose a Raspberry Pi case color that matches your budgie's coloration
How to set up Budgie Cam to run on your Raspberry Pi
- From the terminal, clone the repository.
git clone https://github.com/shannonturner/budgie-cam.git
- Install virtualenv if you do not currently have it
sudo pip install virtualenv
- Create a virtualenv on the cloned repository.
Now the virtualenv will be active; you can activate it again later on by running
source bin/activatefrom within the budgie-cam directory.
With your virtualenv active, install the required Python packages
pip install -r requirements.txt
- Edit the budgiecam/settings.py file and change the SECRET_KEY to be a non-blank string of 50 random characters. You can generate a secret key by running this Python script:
from django.utils.crypto import get_random_string chars = 'abcdefghijklmnopqrstuvwxyz0123456789!@#$%^&*(-_=+)' print get_random_string(50, chars)
- Edit the txt2pi/twilio_credentials.py file with your ACCOUNT_SID and AUTH_TOKEN from your Twilio account. (If you don't have a Twilio account yet, you'll need to create one at: twilio.com)
7a. Your Account SID and Auth token are available on your Twilio Dashboard under Project Info: https://www.twilio.com/console
Make sure that your Raspberry Pi camera is running correctly by running:
raspistill -o(if it doesn't work you may need to enable the camera and restart your Raspberry Pi by running
Install Apache according to this guide: https://www.raspberrypi.org/documentation/remote-access/web-server/apache.md -- this will allow you to serve images that Twilio will be able to find.
Open a browser and go to http://localhost and you should see a "It Works!" page. (If you are running in command-line mode rather than the desktop mode, you can start desktop mode by running
From your terminal, change your directory to /var/www/html (if that doesn't exist, use /var/www/)
- Create a new folder for your pictures.
sudo mkdir budgiecam
- Change the permissions on your new folder to allow you to add items to this folder. If you are logged in as a different user than
pi, then substitute your username in place of
sudo chown pi: budgiecam
From your browser, go to http://192.168.1.1 to log in to your router. You will need your router's administrator password.
Find the IP address of your Raspberry Pi, usually 192.168.1.XXX. Write this down.
Find your external-facing IP address (the one that does not begin with 192.168.) Write this down; you'll use this external-facing IP address to tell Twilio where to go. In later steps we will use the example IP address 126.96.36.199 so when you see this, replace it with your own.
Note: If you have a dynamic IP address, your IP address may change without warning and your Budgie Cam may stop working until you update your new IP address in Twilio. This does not happen frequently, but it may happen periodically depending on your internet service provider.
- You need to set up port forwarding for two ports. Your first port forwarding will allow access to your Apache web server that serves the images taken by your camera.
For my port forwarding, I set up requests to my Raspberry Pi's address with a port of 80 to go to a destination of XXXXX. (In place of XXXXX, use any number you like)
So it looks like:
Raspberry Pi 192.168.1.xxx:80 Destination XXXXX TCP Any -> XXXXX
This will allow my images to be found by Twilio. In place of XXXXX, use any port number you like as long as it is not in use by another service or system.
Your second port forwarding will allow POST requests to go through to the Django server you will be running soon.
It will look like:
Raspberry Pi 192.168.1.xxx:YYYYY Destination YYYYY TCP Any -> YYYYY
Again, which ports you use for XXXXX and YYYYY don't matter much as long as they are not in use by something else.
Your port forwarding system may look different depending on your router.
- Edit the txt2pi/budgie_settings.py file with your BUDGIE_PASSPHRASE, BUDGIE_FILE_PATH, BUDGIE_WEB_PATH, and RASPI_IP
BUDGIE_PASSPHRASE: Budgie Cam will check to make sure that this password exists somewhere in your text message before taking a photo and sending it back. While not essential, it's probably a good idea since this is essentially a camera in your home.
BUDGIE_FILE_PATH: This is the file path of where the photos are stored, created in step 12 above. (example: /var/www/html/budgiecam/) If raspistill is unable to save your photos or they are being saved in the wrong place, check this setting and make sure you are using a trailing slash.
BUDGIE_WEB_PATH: This is the web path where your images are accessible from the web. If you followed the instructions and are using /var/www/html/budgiecam/ for your BUDGIE_FILE_PATH, your BUDGIE_WEB_PATH is then /budgiecam/. If Twilio is unable to locate your photos, check this setting and make sure that you are using slashes properly.
RASPI_IP: This is the external-facing web/IP address of your Raspberry Pi as found in Step 16. This is your also your HOME'S IP ADDRESS so you probably do NOT want to commit this to GitHub (Same with Django's SECRET_KEY). If your IP address changes as noted in Step 16, you will need to update it here and in Twilio. Use the format: http://188.8.131.52:XXXXX where XXXXX is the port number you used in port forwarding in Step 17.
- Run the Django server:
./manage.py runserver 0.0.0.0:YYYYY
Note: Using 0.0.0.0 (instead of localhost) acts as a wildcard, allowing any computer on your network to access the device, which can be useful for testing.
Purchase a phone number from Twilio ($1/month) with SMS capability
In the Twilio Console, configure your phone number to send a POST request to your Raspberry Pi when it receives an SMS message.
In the Configure tab for your phone number, scroll to the bottom under "Messaging." Where it says "A message comes in", enter the web/IP address of your Raspberry Pi's Django server as noted in Steps 16 and 19.
If you followed the instructions, yours will be something like: http://184.108.40.206:YYYYY/budgiecam/ where 220.127.116.11 is your IP address from Step 16 and YYYYY is your port number from Step 17. /budgiecam/ is the path used by the Django URL, so you don't want to change it. Be sure to use trailing slashes.
Use HTTP POST as the request type.
Save your phone number's configuration.
- Let's test to make sure everything is working. From your browser, go to http://localhost:YYYYY/budgiecam and you should see a message saying that your Budgie Cam is configured and ready to go! (Remember to replace YYYYY with the port you used in Step 17)
22a. You can also test to see if your port forwarding worked correctly by opening a browser on a different computer connected to your home router and navigating to http://192.168.1.xxx:YYYYY/budgiecam, where xxx is your Raspberry Pi's IP address and YYYYY is the port you used in Step 17.
Save your Twilio phone number in your phone as Budgie Cam so you can send a text message.
Send a text message from your phone that includes your BUDGIE_PASSPHRASE from Step 18. Wait about 10-15 seconds. Watch your Django's runserver output to see any logging messages. If all goes well, you should see a 200 POST request. If something went wrong, you'll get a 500 error and a clue with what you need to fix.
Optional but recommended: Create a startup script so that your Budgie Cam will run automatically when you start your Raspberry Pi without any input from you.
sudo nano /etc/rc.local to open the file rc.local with the editor nano. If you have a preferred editor, you can use that instead.
Add the following code before the
cd /home/pi/budgie-cam/ . /home/pi/budgie-cam/bin/activate /home/pi/budgie-cam/bin/python /home/pi/budgie-cam/manage.py runserver 0.0.0.0:YYYYY &
Remember to replace YYYYY with the port number you used for Django in Step 17.
If your budgie-cam repository was not cloned into the /home/pi/ directory, or if you put your virtual environment somewhere else, you'll need to adjust the paths accordingly.
Don't forget to include the ampersand at the end of the command, which is important because the Django server doesn't finish running -- it's always on. This ampersand allows the startup script to finish correctly.
Once you have saved your script (Control + X to Exit, then Y to save, then Enter to confirm the filename) then you will want to
sudo reboot to reboot your Pi. From now on, Django will run automatically at startup. So if there is a power outage or your Pi gets unplugged, it won't be an issue to get it back up and running without plugging in a monitor and keyboard.
Mount the camera and Pi on your cage and enjoy!
If you're still reading this and have completed all of the steps I would love to see your beautiful bird. Send pictures you've taken with your Budgie Cam to me!
- If your picture comes out upside-down, change the FLIP_CAMERA variable in txt2pi/views.py to True
- Budgie Cam also supports videos. Just put "video" in your text message and it will take a 30 second video. Don't forget your BUDGIE_PASSPHRASE!
- Budgie Cam also supports audio. Just put "audio" in your text message and it will take a 15 second audio. Don't forget your BUDGIE_PASSPHRASE!
- Having pictures on your phone is nice but you may also want them on your computer. I've included a script that will back up for you, in pix/budgie_backup.py -- you will need to
pip install Pillowand
pip install requestsfor it to work, and if you are using it to back up videos it will download your videos and convert them from h264 to mp4 but this requires special software, ffmpeg.
- If you take a lot of photos and/or videos, you may eventually run low on storage space. You may want to create a cron job to delete old photos and/or videos. Alternatively you can delete them manually by logging in to your Raspberry Pi remotely. From another computer, run
ssh firstname.lastname@example.org xxx is the IP address of your Raspberry Pi.
