Aquarium Fish Feeder

Step 1 : Print alls parts

For this, you need a 3D printer and ~100g of plastic (PLA).

Find all stl files in the folder "3D_print" and print them.
Instructions:

  • Nozzle: 0.4 mm
  • Filament: PLA
  • Layer height: 0.2 mm
  • Infill: 10%
  • Support: Yes for Holder (60°), No for Other parts
  • Wall thickness: 2.0 mm (5 wall lines count) for Holder, By default for Other parts
  • Disable "Union overlapping Volumes"

Step 2 : Assemble all parts

For that, you can see my video on YouTube. (5:02)

Step 3 : Install raspbian on your Raspberry Pi

  1. Download Raspbian OS
  2. Flash a SD card with the zip file by using balenaEtcher (for exemple)
  3. Plug the SD card into the Raspberry Pi and turn on the power.
  4. Follow the instructions on the screen to install the Raspbian OS.

Step 4 : Import the repo on your Raspberry Pi

git clone https://github.com/SylvJalb/Aquarium-Fish-Feeder.git
cd Aquarium-Fish-Feeder

Step 5 : Installations

pip3 install -r requirements.txt

Make sure you have gunicorn installed. Do the command which gunicorn and make sure you have the good path in run.sh (last line).

Then define your environment variables in env.py (nano env.py):

timezone_name = "Europe/Paris" # Your timezone
pwm_gpio = 12 #Use pin 12 for PWM signal
frequence = 50

# Positions of the servo (in degrees)
posFeed = 160   #Position to drop the food
posReload = 30  #Position to reload the food

Step 6 : Network configurations

Go on your internet router panel and configure your DHCP to define static IP to your Raspberry Pi.
Open the port number in your router panel and configure it to your Raspberry Pi. (tcp protocol)

Step 7 : Start the service

./run.sh

If you want to automatically start the service at boot, create /etc/systemd/system/feeder.service file:

sudo nano /etc/systemd/system/feeder.service

Paste this content, then modify paths to your files:

[Unit]
Description=feeder service

[Service]
User=pi
WorkingDirectory=/home/pi/Aquarium-Fish-Feeder
ExecStart=/bin/bash /home/pi/Aquarium-Fish-Feeder/run.sh
Restart=always

[Install]
WantedBy=multi-user.target

Then, do sudo systemctl enable feeder.service to activate the auto-start of the service after each startup.

To start the service, do sudo systemctl start feeder.service

Step 8 : IFTTT configuration

Go on your IFTTT account and create a new webhook. Add a Applet : IF you condition... THEN use webhook like this:

Now you can see the logs (dates when the feeder have been feeded) on this link:
