During my physics PhD I built my own Segway (and a second one with a power tool company who came to me after first asking tlb) and did a bunch of projects with a high-power laser cutter that I got funding for in our lab. I included these on my resume and they were much easier for interviewers to talk to me about than my PhD work. I think they also helped me stand out a bit. Receiving positive feedback about these projects gave me confidence to sell myself as someone who could build things.
