Optical Data Link

This one started when I read somewhere that LEDs emit a small voltage when they're exposed to light. I figured it was popycock, but nonetheless put a voltmeter on an led and shined a flashlight at it. Sure enough, a handful of mV showed up.

Armed with this newfound info, I whipped up some quick proof of concepts and was impressed with how easy it was to send data both ways with these. I have big plans for this, one day I'll make them happen.

Oh you just slap some elmers glue on the pcb and sprinkle the components on, easy peasy
