I've been doing some research on some lower cost alternatives than the prebuilt optics, and found that some of the cheaper stuff uses an spi interface and I wondered if a screen with a beam splitter would work without any other lenses or would I need a fresnel lens? (or any other lens)
link to the display im thinking about:
also Ive been looking for development boards other than the pi zero so i can run some more advanced stuff like face recognition and just having extra power for the future, anyway i found some other sbcs like lattepanda or orangepi, would it be worthwhile getting a more powerful one or not?
I don't have a concern with power as i have a load of lipos that i can regulate down to 12v or 5v (also they work as portable chargers as well)
