1. Follow the instructions here for configuring your Raspberry Pi for headless mode and connecting via SSH.

2. Once connected via SSH, setup the project with the following command:

   $ source <(curl -s https://raw.githubusercontent.com/QnnOkabayashi/scripts/master/PiDiffuserCam/setup.sh)
   

   Warning: You should always verify that scripts from URLs are safe before running! Check out the source code below yourself.

   Source code

   This will:

   • Update the package manager
   • Install the required dependencies
   • Clone the project repo code to the home directory
   • Enable the PiCamera and RealVNC modules
   • Display VNC server address
   • Reboot, enabling the VNC server

   Note: Sometimes this code doesn't do anything for reasons beyond me. If it doesn't work at first, wait a minute and try again.

3. On your local machine, install VNC Viewer.

4. Open VNC Viewer and enter the VNC Server address the setup process displayed in step 2. This will open a window where the camera feed will display when we enable it.

5. To start taking pictures, SSH into the Pi, navigate to ~/PiDiffuserCam/raspberrypi, and enter:

   $ python3 main.py
   

The scp command can be used to transfer files over SSH. The following command transfers images from the Raspberry Pi to your desktop (executed from your local shell):

$ scp -rp [email protected]:/home/pi/PiDiffuserCam/raspberrypi/captures /Users/$(whoami)/Desktop

Note: This command will fail if no images have been captured

1. After transfering the images to your computer, convert them to .tif by renaming them.
2. Clone the tutorial code repository into a Jupyter Notebook.
3. Upload them to the Jupyter Notebook and edit the config block (shown below) by entering in the image file names:

   psfname = "./psf_file_name_here.tif"
   imgname = "./image_file_name_here.tif"

4. You can also change the number of iterations for tweaking the clarity:

   # Number of iterations
   iters = 5

5. Restart the kernel to execute script, and the reconstruction will display at the bottom.
