This is a complex process, but the guys at Graffiti Research Lab have armed you with detailed written instructions and this video on how to create a night writer. This is a more complicated version of their LED throwies that allows you to catch a tag in lights. You'll never need an airpline skywriter again!
The night writer extends the functionality of LED throwies by allowing a writer to catch a tag in lights. It's cheap, easy to make and writes 12-inch glowing letters 25-feet in the air on any iron or steel surface if you stand on a turned over garbage can.
1/2-inch, 3/16-inch and 1/8-inch foam core, preferably black
Paint Edger attachment
15-foot telescoping pole
A few hundred LED throwies
Shrink Tube or electrical tape
Cut a 10-inch wide strip of 1/2-inch and 3/16-inch foam core. The length of the strips will be determined by what you want to write. For each letter add 3.75-inches in length. Cut both pieces of foam core the same length. Now graph out a 1.25-inch square grid on the 1/2-inch foam core. Make a 1/2-inch diameter circle at the intersections and cut a hole in the foam core using short cuts tangent to the circle (Fig 1).
Once you have cut all the holes into your 1/2-inch foam core, use the epoxy to glue the 1/2-inch and 3/16-inch foam core strips together. Use the epoxy the fix the paint edger attachment on the back of the night writer (Fig. 2a). Cut 1-inch wide strips of the 3/16-inch foam core about 1-foot in length, and cut 1/2-inch wide strips of the 1/8-inch foam core 1-foot in length. Epoxy these strips together and then epoxy them on the front of the night writer with the 3/16-inch foam core side down (Fig. 2b). These stand-offs are the secret ingredient. Once the epoxy has set-up (about 5-7 minutes), you can screw the painter attachment onto the telescoping pole and get ready to load the night writer (Fig. 2c).
