If you're looking for a bit more flexibility around the current and voltage setting as well as a more solid mounting option and safety features, take a look at fpx board [1]. fpx is open source.

I love the configuration method! I used something similar for a security token project I did.

Very interesting.

There are so many USB charging standards - I had been thinking that it should be possible to construct a universal USB power converter. (Even in the case where the charger can't supply the watts the device wants, you could accumulate some energy in a small battery large cap and charge intermittently). But I suspect the reason it hasn't been done so far is liability - there are bound to be a few devices that don't play ball and blow up.

I don't have a need for this right now, but I love your method for configuration. It seems really easy and user friendly :)

That's really cool. Will keep it in mind for future projects.
