Your entrepreneurial drive is admirable but it sounds like you may be missing "the business" and "market analysis" parts that are necessary for viability. You might consider teaming up with someone who can help you with the business side aka "demand side" of things. I say this because while your technology skills might be superior, making the "right" product at the right time and a focus on who your customers are and what they need is equally if not more important. Generally the idea that a better mouse trap will result in customers beating a path to your door is a falsehood(most of the time). Know your customers. Know what they need, why they need it, and when they need it. You should be able to name your top 50 potential customers by name and understand what they are willing to pay you to solve their problem. If your product is relatively inexpensive you better know your top 1000 customers by name. It takes that level of customer engagement to be successful. You will also need to understand the economics of the problem and solution. and so on... In short don't give up, but focus more on what you are doing wrong and compare your attempts to those who have been successful. My guess is that coding and engineering is not your problem because it rarely is. Start with understanding all the things you might build and the demand for each as well as your ability to create it economically rather than starting with what you can easily build. An obsessive focus on the universe of problem domains you can address is always the best place to start. Most entrepreneurs jump to development prematurely.
