Re: Night vision LED
Y'know, that's pretty much what I had assembled myself last week. I s'pose it's no surprise that I'm a geek though.
Of course, I used 26 gauge wire and connected both LEDs together with the battery in a croakie strap. And I used red LEDs, which preserves your night vision if you don't care about color rendering...
I also tried the single red LS on the glasses-bridge trick. That was a bit too much, the red light reflected off what you're reading is too intense. When you switch off the light you get this cool blue after-image though, which gives you the illusion of being able to see in the dark.
