Ever wanted to make your own LED? You might be tempted to after reading how easy it is. No, this won’t really be a practical LED that you would use to light a project, but it is very cool anyway. [Michael] picked up a box of Moissanite, or Silicon Carbide, on eBay for roughly $1. Making the LED is as easy as putting your positive lead to the crystal and touching it with a sewing needle attached to a negative lead. He has tips on how to get the best results as well as a little bit of history of LEDs on the site.
