This resonates so well with Engineering in an unexpected way for me: the "production" version is orders of magnitude harder than the prototype. I kist expected it to be plainly harder.

I'm not talking just about programming. At my University I used to make robot arms and RC stuff with my classmates. Polystyrene, Arduino and a lot of duck tape were our friends, winning even a NASA competition. It was actually quite fun and fairly easy.

After finishing and while I was freelancing, I tried to take it to the next level. Once you get to rigid pieces and tight couplings, there is a huge amount of details and gears that I don't even know how to start searching for. What I learned at my University (Industrial Engineering) won't work as well, since I am not ready to order 10000s of pieces.
