What about option 5: Learn while doing, or more specifically while someone else does and teaches you. You're clearly highly skilled in your technical niche why don't you find someone else with complimentary skills (mechanics, electronics and computer science) and partner with them. You can start building your business immediately in the time that you have and as part of the partnership each teach the other. I know that as a hacker having the opportunity to work with a real specialist in another field and for us both to teach each other would be a massively satisfying experience. You get two benefits the way I see it 1) You can start building your startup now 2) You get the two skilled specialists to work on it and share the excitement I see the only drawback is that you don't get to go and spend a few years learning a new thing without any commercial pressure. If this is about learning how to be a hacker that's bad but if you're really into the startup thing then you save yourself a lot of time.
