I'm personally in line with the OP where I don't have any fully formed side projects that I would feel very comfortable as a reflection of my current ability. I really like stackoverflow for this exact issue. Spending time with family is just more important than coding, but I'm able to easily/quickly contribute to stack overflow during work or in the off time. If someone is interested in seeing examples of how I think, help or code I can say, look at the 1000 answers on stackoverflow :p
