CoffeeBox

A GUI app in python to manage the cash for coffee with a Raspberry Pi.

1. Annotations

  • Readme under construction
  • Raspberry pi 2b model was used
  • Python 3.9 was used for the program
  • Ensure installation of tk bootstrap for extended gui visuals

3. Install Python 3.9

To install Python 3.9 on a Raspberry Pi running the Raspberry Pi OS, follow these steps:

  1. Open the terminal on your Raspberry Pi.

  2. Update the package list and upgrade the system packages by running the following commands:

    sudo apt-get update
sudo apt-get upgrade

  3. Install the prerequisites needed to build Python from source:

    sudo apt-get install build-essential tk-dev libncurses5-dev libncursesw5-dev libreadline6-dev libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev libffi-dev

  4. Download the latest version of Python 3.9 from the official website using the following command:

    wget https://www.python.org/ftp/python/3.9.9/Python-3.9.9.tgz

  5. Extract the downloaded archive using the following command:

    tar -xf Python-3.9.9.tgz

  6. Change into the extracted directory using the following command:

    cd Python-3.9.9

  7. Configure the build process using the following command:

    ./configure --enable-optimizations

  8. Start the build process using the following command:

    make

  9. Install Python 3.9 using the following command:

    sudo make altinstall

    Note: the "altinstall" option will install Python 3.9 alongside the system's default Python version, which is typically Python 3.7 on Raspberry Pi OS.

  10. Verify that Python 3.9 is installed by running the following command:

    python3.9 --version

That's it! You now have Python 3.9 installed on your Raspberry Pi.

4. Hide cursor in Raspbian

  1. Open the terminal on your Raspberry Pi.

  2. Edit the lightdm.conf file using the following command:

    sudo nano /etc/lightdm/lightdm.conf

  3. Add the following line to the [Seat*:] section of the file:

    xserver-command=X -nocursor

  4. Save the changes by pressing Ctrl+O and Ctrl+X.

  5. Restart the Raspberry Pi to see the changes take effect:

    sudo reboot

5. Download on your raspberry pi

  1. Download the latest stable release:

    wget https://github.com/m31L3r/coffeebox/archive/refs/tags/V1.3.tar.gz

  2. Unpack the downloaded file:

    tar -xf V1.3.tar.gz

6. Install ttkbootstrap

To install ttkbootstrap on a Raspberry Pi, you simply run:

sudo pip3.9 install ttkbootstrap

7. Automatically start the python app script on startup

You can use the /etc/xdg/autostart directory to autostart your Python script. This directory contains .desktop files that are used to automatically start applications when the desktop environment starts up.

  1. Open a text editor and create a new file. Name the file something like my_program.desktop.

  2. Add the following lines to the file:

    [Desktop Entry]
Type=Application
Name=My Program
Exec=/usr/bin/python3 /path/to/your/python/program.py

    Replace My Program with the name of your program, /usr/bin/python3 with the path to your Python interpreter, and /path/to/your/python/program.py with the actual path to your Python program.

  3. Save the file in the /etc/xdg/autostart directory.

  4. Reboot your Raspberry Pi to apply the changes:

    sudo reboot

Now your Python script should automatically start when the desktop environment starts up. Note that this method assumes that you're using a desktop environment that reads the .desktop files in the /etc/xdg/autostart directory, such as LXDE or Xfce. If you're using a different desktop environment or window manager, you may need to use a different method to autostart your program.
