Ant. prototype 2 Battery lid

This is the second prototype version of the casing for the Ant. PCB second version. The aim is to hold an electric circuit, enable the connection of a DC nano grid with a communication channel and last but not least, that the user interface is the easiest and more comprehensible possible. This is because the end users of the product will be people in rural areas in developing economies.
most of the holes are for LED's, this LED's are being used an indicator of the nanogrid network status, the status of the device. In this prototype some capacitive touch sensors will be tested, this will be located under the numbers. some holes were added for push buttons, in case the capacitive touch sensor doesn't work.
This is all part of a thesis but if you want more information about ant please visit http://ant-tech.org/
Any kind of interaction with this post will be highly appreciated. I'm trying to test colbaorative design techniques and social product development techniques. So your input
