I was just thinking it would be great to be able to scan any food we buy store it in a database (I was thinking on my raspberry pi) then with a web interface be able to see what food we have and also recipies by some sort of scraper depending on what we have available. One of the problems I could think of was that some items (especially fresh food )dont have barcodes but I suppose you could just have a card with barcodes for those things.
I have been searching but not found anything like this yet.
My question is, has someone already done this and if so are there detailed instructions with sketches and which hardware was used? 8)
