How do you expect to learn the basics and the theory without taking some basic lessons? Much of what you learn doesn't come from books, but from the interaction with people, other students, professors, workshop people, etc. The feedback of the people surrounding you, their ideas and the way they perceive the products opens your mind, make you realize of things you wouldn't on your own. Here in the forum you could get feedback and make a progress with your skills, but I doubt it'd be enough to land a proper design position.
Most companies ask for the degree itself, without that many doors would be automatically closed for you. In a way you are lucky you found out you wanna be a designer when you are 24, I have friends who realized of that with 26 - 28, some others are older and still don't know what to do. These guys who did would work part time while studying and still be among the top students. I don't mean you are not gonna get it without going to a design school, but it's gonna be much harder.
Having an eye doesn't make you a designer, there's much more to it that just having good taste. You should be able to explain why that product is cooler over this other, be able to give the reason behind it in a way people would agree with you. That you enjoy working with your hands is great, that's a must for a designer, same with computers or combining the technical and the artistic side. Now you would need to develop those skills up to the level of a professional designer and I believe the best way to do it would be going back to uni.
