You know what you could do is, sketch out concepts for that handheld product, show the cad images, then do a few final renderings. That would make the project complete. It would basically flow like sketch-prototype?-CAD-final render.
Blogging isn’t bad (don’t take it from me though, I haven’t started a blog yet), but you should focus on making either the existing projects you have better, or starting a few new projects that surpass your current ones. Like I said before, fewer “squares” but with more depth in each.
You know what I didn’t see? A product that was directly influenced by your travels; something only someone like you could design because you’ve been there, interacted with the people and saw a solution. That would be a great tie-in to your traveling and how it supported you as a designer. Again, best of luck.
