Well, first you are 'hijacking' a thread, which somebody will tell you about, not so nicely I'd guess...
But, at the top of the page is a menu bar with a search option. There are many threads dealing with all your requests.
The 25 reply requirement, before starting your own thread, is to limit the number of people posting advertisements and students whose only interest is to have their homework done for them in a hurry.
There are a lot of helpful and knowledgable people here, but you need to respect the fact that we all have our own projects to work on, and most won't bother doing yours for you. You need to get started, then ask about specific problems you are having. Search here and on the web first, find the circuits that at least come close to your needs, then ask about how to get them working, substitute parts, ect...
