Here are two easy projects using 3 mm ultraviolet LED's and a solar cell with a boost circuit. Based on a Joule Thief, and here the joule refers to the unit of energy not anything stolen. The concept of edge lighting acrylic or plexiglass, persplex, if you are in Great Britain, has been around for a long time. But, there always seems like there is more to do with the idea, and so I offer these simple ideas. The solar rock lights shown in the photo and in the video were purchased at a Dollar Tree store for a dollar of course. But, they are available online in single or case quantities if you decide to make and sell these little note boards in a frame. After the video there are inset closeup photos and links to follow. These "electronic noteboards" are available already assembled for $7.95 at American Science and surplus. I have not seen them for real so I am not sure how they really look. And for other "neon effects" see my page on Odd n' Ends, under neon. Enjoy!
