Some of the best engineers I know don't have their degree in Engineering even, but in Mathematics or Physics, but they have a passion for learning and bettering themselves, so don't let the lack of a degree in CS/CE discourage you. that being said, I'll diverge here and say you should learn a lower level language (C, C++, Assembly, ADA). You'd have a world of opportunity in more regulated industries, such as Vehicle Manufacturing, Industrial Controllers, Aviation, weapons, etc. You'd have a leg up on anyone coming directly from CS or computer engineering with a background in Physics/ME. And in that case, I'd say get yourself a Raspberry Pi and jump-in to the world of Embedded controllers & OS. It will be a very steep learning curve, but you'll develop great chops and a lot of knowledge. and, on a side-note: People still get paid to develop new trash-cans? I thought that was like... a solved problem.
