The first rule of knowing if a market exists is to define what you are making and then figure out who it's for. Then pitch to that person the benefits of your product. Alas the FAQ page lacks both of these questions. I'm left with no idea -why- I'd buy this thing. What utility does it have? What is it supposed to replace? I think you can stop worrying about the FCC issues with it. You won't sell any of these (at least not with this FAQ page). Your whole "discussion" is technical and doesn't mention utility once. It sounds to me like you're building this because it's fun to build and scratches an itch. But it's not a product, much less requires you to start building and designing new hardware. So well done on at least skipping that investment. If you want to make a hardware product then early about utility first. If it's useful then other things flow from that. Not the other way around.
