Although I wish he was a wee bit less overconfident. :) BTW, why "on the other hand"? I don't think that what you said, contradicts what I wrote above. > And sometimes it is good to start from scratch and really get innovative. > In this case he does not have time to market issues and thus he > can have more choices. The danger here is that even seasoned engineers get frustrated and bored with their hobby projects. There's no better way to boost one's motivation, than to actually complete a project. There are few things worse than having people remind you about that calculator project you started a year ago. Using an off-the-shelf solution does not mean you can't start from scratch and "really get innovative." It means you'll learn new things, have a better chance of successfully completing your project, and have more fun doing it.
