I have discussed most of the projects many times at length over the last decades on BIX which retained all postings in archives.
Pretty well everything I have to say about each project is spelled out here. I don’t have extra material to give you, unless I explicitly mention it. I don’t have the time to lead you by the hand through a project. If one project is too difficult to tackle at your current level of skill, pick a simpler one.
If you are unemployed, or just out of school, you might hone your skills by tackling some of these projects. They are more like the real world problems you will be given in the workplace. In the real world you have to write the specifications too. They are not handed to you on a plate the way they are in school. I give you many hints on how to solve the problems, far more than you would get in the workplace. These problems are intermediate in degree of hand-holding between school and the workplace.
I would be happy to implement any of these projects for you, for a fee, though I do not do homework.
