I'm currently working on an interesting project for my pantry. I have literally dozens of glass milk bottles of different sizes which I use to store dry goods. And yet, sometimes it's confusing trying to differentiate semolina flour from something similar like ground cornmeal, for example. Plus, there are times when I wish I had the original instructions or nutritional information handy.
So I thought that I would design my own lids as replacements for the milk jugs and to embed RFID chips in each. That way, they would be waterproof, stand up to repeated washes and yet allow me to programmatically determine what's inside each container.
So, I'm thinking Raspberry Pi with NFC RFID reader and the average hoodoo to deliver the information.
The second version was a perfect fit with just a slight adjustment on the sizing. It took an hour in Autodesk Fusion 360.
