Completely homemade smartglasses

Sun May 19, 2019 9:00 pm

Hey guys...
I’m a beginner on the Rasberry Pi, and I’m going to make some smart glasses. I’m using a toy spy car that could transmit video to a headset to create the NED (near eye display). By breaking open the headset, I found that it uses the CyberDisplay 300M LV LCD display by KOPIN. I’ve even found a data sheet for this obscure display: https://www.electronicsdatasheets.com/d ... format=pdf. The sheet states that the display has the same display architecture as the industry standard LCD monitor or TV. This should enable it to connect to a Pi through the GPIO pins. However, I can’t find out which inputs I’ll need to connect to which pins, and if I’ll need a certain driver. Inside the headset is also a KOPIN A300 controller: https://datasheetspdf.com/pdf/672941/KO ... -A300-QB/3. I don’t think it should be necessary to include this, but I’m a noob. If ANYONE can help out, I’d greatly appreciate it. I’ve included some images below for reference.

It needs a NTSC or PAL Signal. In Raspberry is HDMI. This will not work.

All Pi models have Composite Video output in NTSC or PAL. On the Zero you need to add your own connector, but the others have either an RCA/Phono Jack (very early models) or the TRRS A/V 3.5mm socket.
