For Valentine’s Day this year I have created an led heart in a light bulb lamp.
In this video I give some information about UV (Ultraviolet) Led Wavelength, How to calculate the series resistor value, some simple ways to wire or connect them and then look at a few items that glow under ultraviolet light.
In this article, I am going to describe how you can make a Star Wars led edge lit sign.
The sign is engraved on a clear acrylic sheet. I have used an A4 sized 3mm thick sheet, which is common in Europe. In the US where A4 sheets are not as easy to obtain then you can use 8″ x 12″ x 1/8″ which is a similar size.
To obtain the Star Wars effect I have used a gloss black acrylic sheet behind the clear sheet.
