Ever think those old diodes lying around are just junk? Well, apparently they can be more useful than you'd expect. Dhananjay Gadre discovered that if you wire up a basic 1N4148 or 1N914 diode the right way, you can make it photosensitive. Kinda wild, right? I mean, I just toss those diodes in a drawer, and now I find out they could be doing something cool instead of gathering dust. Makes you wonder what other old tech we overlook. Anyway, maybe I'll try it someday... or not.
