Thank you for the prompt reply, but I think I need to explain further. I'm working on a set of night vision goggles. First (now that I put more thought into it and studied up a bit), I plan to connect the NoIR v2 cam to a Pi Zero and run the HDMI output of the Pi Zero directly into a set of Eyezone 720P HD FPV LCoS Goggles. This will be an initial working prototype that will require no modifications to the goggles, and I think I'll incorporate a Pimoroni Enviro pHAT with a HUD overlay for good measure. I'm pretty sure I can find enough instruction online to pull this together. Is the Pi Zero capable of working with the Enviro pHAT and producing a HUD overlay while maintaining 720p HDMI output at a steady 60fps from the NoIR v2 feed?
For phase two, I plan to have a pair of NoIR v2 cams feeding as directly as possible into their respective LCoS displays for stereoscopic vision (hopefully), thus eliminating all the stock electronics in the goggles except the pair of displays. I do not have a model number or data sheet for the displays yet, but I am certain they will have flat flex cables. To accomplish this, it looks like I may have to get a pair of Pi 3 units. The Pi Zero does not seem to have a flat flex connector for display output, while the larger versions do. So there will be two (camera)(dedicated Pi 3)(display)
systems running independently, and perhaps I could incorporate the Pi Zero with the Enviro pHAT from the initial working prototype and feed the overlay info into each of the dedicated Pi 3 units. What do you think about this?
And for phase three, is there anyway I could have a system like this condensed down into one custom PCB that does it all? The Raspberry Pi units can certainly help in developing something like this, but there are a few things about Raspberry Pi that I don't want in a finished product like night vision goggles. First, the boot-up sequence is a bit much for something I expect to just turn on and work. And I've seen that it's good practice to properly shut down the Pi units to avoid corrupting the operating system on the SD card. Ideally, I need one PCB that can fit inside the goggles, preferably right over the display/optics modules, that can handle a pair of NoIR v2 cams feeding 720p @ 60FPS into a pair of LCoS displays independently, with HUD info gathered from something like the Enviro pHAT, perhaps with other functionality like screen brightness and contrast, and can power up and power off immediately with no problems...tall order, right? Oh, and it has to be very energy efficient, lol.
