Chances are, you know an engineer or two, whether it’s a friend, coworker, or family member. If that’s the case, you’ve also probably noticed that engineers have some pretty unique interests. While that’s great and all, it can make gift shopping challenging. When I tell my family what I want for Christmas every year, I usually get responses like, “What even is that?” or “That seems like such a boring gift!” So whether you are doing some Christmas or birthday shopping for an engineer in your life, or just a fellow engineer looking for some great stuff to buy, hopefully this gift guide will give you some helpful ideas.
