Below are the excellent notes with links to videos from the original author of Oscar. I can't find a maintained fork, so I have picked this up. The installer should now run on any modern Debian Linux. It has been tested on Ubuntu 20.04, 18.04, and Raspbian.
This version still relies on Python 2. I have found that the Trello module used here does not work in Python 3. I need to research what Python3 to Trello modules exist, and what code changes in Oscar we'll need to make that work. I think I have until the end of the year to figure that out.
I have that project going over at https://github.com/henroFall/oscar3 .
To install this version of Oscar, use this command line:
wget -N https://raw.githubusercontent.com/henroFall/oscar/master/install_oscar.sh && sudo chmod +x install_oscar.sh && sudo ./install_oscar.sh
Oscar automatically adds things to your grocery list when you run out. You just scan the item's barcode on its way into the trash.
Here's a video about it!
I run Oscar on a Raspberry Pi under Raspbian. I use this barcode scanner.
That said, there's no reason Oscar shouldn't work with other hardware.
To install Oscar, run the included install.py as root on the target system. It
will walk you through the process of setting up any API accounts you'll need, and
then it'll install the software.
I haven't really tested that install script, so let's cross our fingers together.
I'm on the Twitters if you have a quick question. For bug reports, use the [issues page][oscar-issues] or submit a pull request.
Thanks to the awesome CloCkWeRX for picking up my slack now that I don't have a Raspberry Pi to test on anymore.
