Csc934 sent in the LED museum, it’s a bit dfficult to navigate the site, but it has a ton of LED history – “The LED. You may not have heard of it, but you’ve seen it. Light Emitting Diode. That’s what scientists & techies call them. They’ve been around for years, and you probably take them for granted. You probably know them as the dim red, yellow or putrid green lights in household appliances, stereos, computers, car dashboards, telephones, and toys. This museum is here to pay homage to the lowly LED and to give you a look into the LED’s past. “ – Link.
