Our camp at Borderland festival is named “The Elements”, and a nice sign will make it stand out.
I laser cut out the letters out of plywood, and the mounting holes in the back plate as well. I screwed in the letters with a few centimeter spacers between.
I made a nice control interface for setting light levels and modes of the sign. I encapsulated it in a great looking aluminium case with rubber seals for weather protection.
The control interface was also engraved by a fiber laser.
WS2812 LED strip was attached to the underside of the letters, aimed to reflect the light towards a light background that would diffuse the light around the letters.
And lastly the letters painted with corresponding colors to make the sign visible in daytime as well at night.
