A love letter, straight from my heart - to the beautiful Light Emitting Diode! In this vlog I go deep into my collection and show some of the very first LEDs ever made, review them in context of the history of LED's, and also show some of the coolest and weirdest kinds of LEDs that you'll see around. This one is for hard-core geeks and dweebs only! Thanks for watching...
