The most significant risks we are currently facing in our project are centered around mechanical design. In order for our setup to be comfortable and the transparent display readable, the mechanical setup needs to be incredibly precise.
For this reason, we both chose to self design the goggles themselves and are putting in a lot of work upfront to work on this CAD design so that we can print, test, and make modifications as needed. For example, if the Pi Zero and battery end up being too much weight on top of the goggles, we may have to consider moving these back and adding a mirror or adding additional straps on top of the goggles. Using fully 3D printed models grants us the flexibility to deal with these issues in stride.
We got a great start on the CAD for these goggles this week, including creating v1 models for the goggles themselves, and additional ventilated housing for the Pi Zero Battery in order to keep it from overheating.
In terms of schedule, we’re still pretty on track. We are meant to start testing hardware next week, but more time is going to be spent on the CAD and working on the design document. As a result, our hardware testing will likely get pushed back until next week. Still, hardware testing really is not going to take us more than a week, so this is not a huge concern.
