Just curious...
Today I noticed that Wal-Mart has a calculator that can be had for $1.00 USD. I'm looking for a numerical LCD display and, for that price; there is no way I could get one thru the electronics supply houses. Is it possible to use items like this for parts or is finding data sheets, etc. on items obtained this way impossible thereby making it foolish to use for hobby projects?
