Junior957 Posted March 14, 2010 Report Share Posted March 14, 2010 Good afternoon everyone,I found this website and forum and I beleive I may have discovered the place where I will learn everything I need.I'm trying to design something really crude for myself and part of what I need involves electronics that are not commonly available off of an old item that I could just take apart. (If it was, it probably wouldn't be nice and small and put together like I would want it to be.)You guys are going to laugh but I need the electronic item to perform two (what I would imagine are) very simple operations. One, to sense two pieces of metal touching eachother and second, it needs to produce a noise (preferably a beep) when that happens.I would imagine the items I would need would be. The first piece of metal, as well as the second piece which is to be struck. A wire, or something to connect that second piece to the circuit board - and of course all the components that it takes to produce the working board, and a small speaker? (And a power source.)I'm the type of person who likes to learn. Even if I never use this information again. How hard of an item would this be to produce? Would this be the appriopriate place to learn?Thank you very much,Ed Quote Link to comment Share on other sites More sharing options...
