Oscar is a Python project utilizing the Raspberry Pi w/ UPC barcode reader to scan barcodes on items you keep stocked in your pantry or fridge, when scanned, ideally when you run out of an item just before throwing the packaging or container away, it will populate your grocery list with the item reminding you that you need to pick up more of that item on your next shopping trip. Since it’s written in Python, it could easily be adapted to run on almost any device with Linux on it and a USB port that is networked. I’ve been working on a fork of it for Python3/Arch and using the miniature UPC reader from Adafruit.
My work on the GTK indicator has kind of stalled, I’ve lost interest but I might pick it up later if I’m ever motivated to work out the kinks in it.
