DIY Google glass but done properly

Now that we have the main hardware (minus the optics) all working. We aim to explain how this project can be modified to suit your needs.

The main advantage of this design is that all the parts are readily available (links in the components section) and that it uses the Composite Video display on the Raspberry Pi, this means these can be used with any existing design without the need for any changes. Every project that has been built with the Raspberry Pi can be used with these Glasses as it uses the existing display and a few parts which are simple to connect. The use of voice protocol and portability mean the Smart Glass can easily be integrated and the addition of a WiFi dongle make the possibilities limitless.

For example, using this to control your music. You could connect your Smart Glass to the WiFi and have a second Raspberry Pi acting as the server with the GPIO connected to the buttons on the remote. If you were to say "Volume UP" the Bluetooth microphone would pass the audio to the Raspberry Pi in your smart glasses. This could send the signal through the Wifi, telling the Raspberry Pi controlling the sound system to "press" the button and increase the volume. 

Another example is access to Google search, the microphone would detect your speech and use the "Search by microphone option" the Google servers would then decode the search phrase just as in Google Glass (but much cheaper!)
