Curved Circuit Art: Make A Double Helix LED Lantern

Step 7 Painting The Circuit

You can of course, leave the lantern unpainted and allow it to weather naturally. But I like the look of copper and chose to spray it with Krylon Crystal Clear Satin Spray Paint. This will keep it from darkening and allow it to be handled without getting finger prints all over it. It also prevents accidental shorting.

You could also cover the LEDs with bits of tape and then spray paint the whole thing a solid color. I tried a metallic silver on some scrap circuit board and it looked quite good.

I think it would be cool to artificially colour the copper with various chemical agents, to make the copper turn blue, green, or rainbow-coloured.
