Kitchen Product Indicator

And in our century: we buy a second-hand PDA (1000-1500 rubles), which barely moves, but still works. We make a program for him (1-3 hours) of such a scoreboard. We hang on the wall. We use it. Before going to the store, we synchronize the data with the mobile phone / default PDA, which is with us. Or we send a leaflet for printing. How do you like it? :)
Looking a little wider - you can not only label products like that, but also other more or less limited sets of products that tend to end at the most inopportune moment: toilet paper, cotton buds, dvd-r blanks, etc. By writing the program, we get the flexibility of customization. The main thing is that the scoreboard is very convenient and clear, in any case, in my opinion :).
I saw it from Oleg Nesterov.
