The next step was trying the AR glasses - for real :-) And then optimizing the position of the transparent screen, and the display and selecting the right magnification, because the display is quite "far" from the eye (distance screen-mirror + mirror-scren+screen-eye)...

This was a lot of fun - even if we look very concentrated :-)

It was during Covid restrictions, we had to wear masks, so you can't see us smile anyway :-)

How would you fix a monocular like that? Initially, we discussed safety glasses! They might be a good idea anyway if you are working with power tools like a hedge trimmer... so here we go:

After all, we are very happy with the success - we have fulfilled our requirements and design targets!
It is a working prototype, operated by an external power bank. But we think this might even be better than having a LiPo battery next to your face - you know, just in case... :-)
Plus it would add more costs (battery + charging circuit) and weight to one side of the safety glasses.
