I always liked the idea from (So Long and Thanks For All the Fish? Definitely from the late Douglas Adams, just not sure which book). There were sunglasses that would go from stylish to absolutely opaque when danger was sensed. They wouldn’t save you, but at least you didn’t have to see your own demise. I think they were from Mostly Harmless. I should find the exact quote.
Back to the serious. The Wif’s dog, bring a naughty create like he is, triggers into the fight of fight-or-flight whenever there is another dog. This would make digital blinders a potential miracle, assuming the blinders didn’t freak him out. LCDs could do the trick, see Naomi Wu’s LCD outfit. This then made me start thinking, kinda like a smart mirror build why not…
Build my own digital sunglasses. Just blackout would be easy, that’s just a change of voltage, but what if I did one better. Get some monochrome LCDs, the reflective type, remove the mirror back, and mount each one as eyepieces in a pair of sunglasses. I could have unique, shade shifting, polarized “smart” glasses.
I’ve been having a hard time looking for a decent size, until I found this which looks like it would fit the bill. Add in some biometric checks, and they could respond to my responses. I’ll have to keep looking though. I might also look into what a custom build would cost.
Other items to consider would be what to drive it with, power source, up time, what to display. I should start thinking about that all as well. I could go with the burley sides method, and I’m totally not against it, but something more elegant would be nice. Researching batteries is making me think I’ll want to power it with whatever I can find, and then custom order. I’ll probably need to start by determining the power needs, and go from there. The pain is the more exotic the shape, the more expensive.
I might think about doing a heads up difficult after gutting an OLED or two.
