Kitchen Products Indicator

Even without knowing German, it is not difficult to guess that the illustration shows an indicator of the availability of necessary products at home (1938, according to the source). The board hangs in the kitchen. You fry the meat, use up the last butter - clicked off the regulator. Poured the last sugar in the sugar bowl - snapped off the regulator. Gathered for food - looked at the scoreboard - it was immediately clear what was needed and what was not. In my opinion, a good solution allows you not to think about this important problem =). And when you get ready to cook something, you can see at a glance at the indicator whether there are all the necessary products for this.

And in our century: we buy a used PDA (1000-1500r.), Which barely moves, but it still works. We make for him a program (1-3 hours) of such a board. We hang on the wall. We use. Before going to the store, we synchronize the data with the mobile phone / default PDA, which is with you. Or send a sheet to print. How do you? :)

Looking a little wider - you can not only mark products like this, but also other more or less limited sets of products that tend to end at the most inappropriate moment: toilet paper, cotton swabs, dvd-r blanks, etc. By writing a program, we get the flexibility of customization. The main thing is that the scoreboard is very convenient and clear, at least in my opinion :).
