Hughes: Introducing the ColorHug open source colorimeter

Since it is open hardware you can probably find a way to make it yourself in the USA or find someone willing to do that for you. There is no reason Hughes has to be the only person building the things!

I guess he intends to add more features too, you might want to contact him to find out if Windows drivers on the to-do list, if I were him I personally would not bother with them.
