What is the difference between yours and the GekkoScience Compac F?
https://bitcointalk.org/index.php?topic=5355470.0Things like this are and will always be a hobby project for people to play with but there is nothing wrong with making it and trying to sell it.
Just keep in mind, you will have to support it, and deal with issues with them and so on.
But, it still looks like a cool project.

This is valid point but more than that I am loving the fact that OP is highly passionate about his project and working on the same since one year now. I think I would love to have such miner in my house running all the time like heater in the corner. I would be more than happy to pay the bills for it since it will be generating something all the time. I am anyway holder of bitcoin so if they just mine and sit in my wallet then also I would be more than happy.
However, this has to be real simple layman consumable product with not much wirings, not much maintenance kind of stuff. Since I am not a hard core miner I would be more focused on the hobby scale and flashing it as if I do mine.

So one positive vote from my end. You should really up scale it and bring the product in market.
