I made something like this back in 2006. I used a HMD I got on ebay that had two screens, one for each eye that gave the appearance of a 40" viewing screen. I slapped a backup camera for a car with 8 IR leds to the front of it with double sided tape, plugged it into the rgb inputs on the HMD and it was good to go. The HMD already came with a battery pack, and I replaced the connector on the backup camera with a 9v battery clip. All together I think it cost me about $120. Worked great for indoor use. Throw in an ir flashlight and it was just as good outdoors.
I was hoping they'd say they used the right Sony low-light sensors instead of spamming IR floods directly (they could have added chiral illumination filters) but that incel-ify function is working 100%. Like where do you put that to hand a person when they say 'yea, I'm something of a nerd, there'? The kancolle hoodie?
