Hey there,

I bought a DiddyBorg and i have done everything like they told me to let the Web Gui work but when i do:

sudo ~/diddyborg-web/diddyWeb.py

This pops up: https://gyazo.com/f4ec28cabe738f7758059bae286b036e

What do i do ?
I use a ps3 controller that is connected , i have no camera setup and no wifi stick .. so just the basic diddyborg.

Thanks for reading :)

The DiddyBorg Web UI expects to have the camera so it can display pictures.

The error you are getting is because the script cannot find the cv2 library, which is used for the image processing.

In order to use the script without a camera connected the code relating to the image display needs to be removed.

I have attached a copy of the script with all of the camera related lines commented out.
This script should work with a DiddyBorg that has no camera fitted.

I am not sure what you need exactly, the script attached to the post above should be ready to go:

  1. Download the script to your Raspberry Pi into the standard DiddyBorg directory: ~/diddyborg
  2. Rename the script so it is called diddyWeb.py
  3. Open a terminal and use the command cd ~/diddyborg
  4. Make the script executable with the command chmod +x diddyWeb.py
  5. You can now run the script using sudo ./diddyWeb.py

Does it work if you use the full path like this: sudo ~/diddyborg/diddyWeb.py

Hi,

When running the script diddy2Web.py I get the following error:
Found ThunderBorg at 15
...
Press CTRL+C to terminate the web-server
Exception in thread Thread-1:
Traceback (most recent call last):
File "/usr/lib/python2.7/threading.py", line 552, in __bootstrap_inner

File "./diddy2Web.py", line 119, in run
retval, thisFrame = cv2.imencode('.jpg', flippedArray, [cv2.IMWRITE_JPEG_QUALITY, jpegQuality])
SystemError: error return without exception set

What is wrong here?

This is not an error we have seen before, but it seems like it might be a problem with the Python library for OpenCV (source here).

It might be possible to fix the issue by ensuring that the cv2.IMWRITE_JPEG_QUALITY is actually the correct type before calling the cv2.imencode function.

Look for this line in the diddy2Web.py script:

retval, thisFrame = cv2.imencode('.jpg', flippedArray, [cv2.IMWRITE_JPEG_QUALITY, jpegQuality])

and change it to match this version instead:

retval, thisFrame = cv2.imencode('.jpg', flippedArray, [int(cv2.IMWRITE_JPEG_QUALITY), jpegQuality])

Hopefully that will get the Web UI working for you :)

The first error means that the script cannot open port 80. The most likely cause is that you need to run the script using sudo, for example:
sudo ./diddy2Web.py

The camera error is because the script failed the first time. You can fix it by restarting the Raspberry Pi.
