So I spend the last 8 months building my own google glass since google glass won't be coming to europe very soon.
For the display I used a Myvu Crystal 701, for the motherboard I used a Measy U2C which has a av out and runs android 4.1.1 Jellybean.
for the battery I used a 3.7V 2500mAh Lithium Polymer battery and a Mintyboost to power the Measy because it requires a 5V supply
for the camera I used a Microsoft Cinema lifecam which has 720p.
to control the device I use a genius finger mouse which is connect to a usb port.
