Make's LED History Movie Is Pretty Cool, Includes DIY Instructions [LEDs]
We all take LEDs pretty much for granted, but the guys over at MAKE have done a good job with this movie that shows the history behind the little glowing things. Turns out the Light Emitting Diode was one of those devices that was more or less discovered by accident, during an experiment at Marconi labs into a Cat's-Whisker Schottky barrier diode made from a chunk of silicon carbide: so MAKE, of course, shows you how to recreate that for yourself.

The patching process, after the jump, isn't terribly complicated.

You may instantly think "Ouch!" but since these are so small and pierce the skin shallow enough to avoid pain receptors, the system is apparently painless.
