Raspberry Pi AR/Smart Glasses

I was thinking about how to improve the display of my glasses, and I think I had found a good way. I simplified the current system, while solving the problems of the screen being had to focus on and it being blurry. They look a bit funny, but not too bad, especially if you wear a hood.

I remembered some 'spy glasses' that I had used when I was younger that had a mirror, allowing you to see things behind you. That gave me the idea.

Basically, the screen is at an angle on the side of the user's head so it takes up less space.  It is then reflected with reflective lens (a.k.a a mirror) into the user's eye. 

This solution works well, if you casually look at it, it is a little blurry, but when you properly focus on it, it is 100 percent clear. 

I did have to remove the lens of the glasses, because they were 3d glasses that did odd things screens.

Here is a picture of the glasses without the mirror(sorry it is not in focus):

And here is a picture of the screen (Again without the mirror)

Finally, here is a picture of what the user sees with the mirror (it looks much better in person)

I want to build a better prototype now and glue the mirror in place, as well as using better glasses and slightly moving the screen.

That means I need to buy a new screen(because I have been using my brother's screen, and I need to glue it into place) and a new mirror that I can cut to shape. While I sort that out, I need to work on the input system. I'll probably start using the Raspberry Pi Zero W with it, so I can use some sort of virtual assistant, as well as a physical input system. I am already working on an HTML based virtual assistant, so I'll develop that further, but tell me if you want me to post a log of it on hackaday.io.

Until then though, mission accomplished!

I’m considering using a new tiny LED matrix screen that should be easier one the eyes. I have designed it on EasyEDA.com to print on JLCPCB.com, although there are a few issues my design. I’ll use their SMT assembly tool to have it come assembled, which starts at £5. The only problem is it will have 16 wires going to a shift register then to the raspberry pi (Or Arduino), so, it may not look great at first.

I also will not be able to make it transparent, but if I put it at the corner, it won’t obstruct your view too much, which also means I can use a simpler magnifying lens design
