I've been working on getting parts together for a prototype of this for awhile now, and I'm awfully close to having them all.

Originally, I had planned on using some glasses that have loupes mounted to them that I found on eBay for electronics work, but mounting the LCDs to them is a bit difficult, to say the least.  I've also found that people like to keep their original glasses on while playing, and use 3D glasses that fit over them, so using loupes is not going to work for that usage.

The plan, as it stands, is to modify safety goggles as follows:

- Make 4 or more holes for bolts
- Make a 3D-printed plate that holds the LCDs and the main PCB a distance away from the goggles' lenses
- Make a thin 3D-printed frame to slide one or more Fresnel lenses in per-eye, to allow for near-eye focusing of the LCDs

The initial PCB will have the following parts:

- 2x LCD connectors (or directly solder the LCD's polyimide FPC)
- Battery pack connector (2 pin 0.1" header)
- controller port
- programming port (might be combined with controller port)
- 3V regulator for LCDs
- ATMega328, with Arduino bootloader for convenience of developers
- Misc. other bits and pieces

I have the LCDs here, and some inexpensive Fresnel lenses (10 for $2!) are on their way.
