We have worked with developer board device project. I think this would be interesting case for you to take next step to execute your knowledge and ideas as business.
Am I allowed to share more specifications with you in this great forum?
We would be happy to hear your opinions, ideas and questions about our product before official launch.
A bunch of hardware features doesn't tell us much at all about the device. How about telling us a name of the device and a website we can go to get as much information as want? I'm not even sure what you want exactly.
I'm taking it as it's a little box packed full of sensors and an API to hook into for easier development with hardware sensory peripherals?
If so it doesn't seem like such a bad idea for initial development projects or prototyping but after that I imaging most people would just purchase the components for only the sensory information they need.
A fair amount of people use API's that have been made for hooking into already existing devices such as the library for the Pi that allows you to use a bluetooth adapter and a Nintendo Wii remote for input. I know it includes the tilt sensors and buttons, I think it even includes sending sound to the speaker on the remote.
