Hi!

In this post, I described how I needed to drastically change the glasses.

So in this post, I wanted to detail some of the changes I want to make with the glasses.

The first change is the display. Whether I like it or not, I need a much smaller display. I found an easy-to-use 128x32 0.91” on eBay and Amazon, and did some testing with a piece of cardboard to see whether it would work. It sort of worked, but I will have to actually try it out.

The next change is the controller. I can’t have the raspberry pi in the glasses because it makes them too thick. That means I’ll have to put them in a small box in the user’s pocket with a battery and communicate with the Arduino (which will be controlling the display) with a NRFL01 module.

I think the Arduino will be an Arduino nano. I had an idea for a custom Arduino with 2 ATMega 328 chips that could work in unison with specially written code, but I don’t think that is needed here.

I thought the basic OS maybe could be handed on the Arduino, then the rest on the pi, but I’ll have to see how that works.

Anyway, that’s all for now!
