I'm thinking of a project with the video glasses and i have a question. Are there two video screens inside or one? I think they're two because in a video about it Lady Ada mentioned taking half of it off. I was interested in using two glasses, taking one screen from each and putting them into one set to make a stereoscopic viewer. ( actually i'd end up with 2 pairs!). This would only work if i could take a screen out of one without breaking it and have it still show video. Has anyone had these apart? A picture of the inside would be good but any help is appreciated.

Re: Video glasses question
We havent taken them apart, but we *think* there are two screens - not sure how it would work with just one - please let us know if you find anything out!

Re: Video glasses question
I did take mine apart and I can report that there are indeed two separate displays inside.
The display unit appears to be a Kopin binocular module
http://www.kopin.com/data/File/BDM230K.pdf.
Each eye appears to be a CyberEVF 230 module, as shown here:

A similar spec can be found here:
http://diyprojector.info/forum/index.ph ... h_id=24575
but this has a 4 pin flex cable rather than 2 jumper wires for the backlight.
It is fairly easy to saw the unit into two single eye displays, with lenses conveniently attached, but
(1) you only have one controller board
(2) the flex cable and power cables are inconveniently short.
There are two PCBs and a controller box with a battery which I haven't opened. The second (smaller) PCB has no components at all, not even a resistor, just tracks. It appears from Kopin's specs that you could ditch the second PCB and the controller box and just feed composite video (+ 3.3V power) straight from a Raspberry Pi.
BTW, the Kopin unit and the housing for it are nice, and convenient enough for tinkering. The sunglasses that are attached to it are extremely low quality. One of the arms of the sunglasses broke off before I did anything with it (in it's case!). If I was a consumer, rather than a tinkerer (and I had not disassembled the unit!), I would have returned it.
