GRL (Graffiti Research Lab) wants you to explore your inner Night Writer and have offered up instructions that you can have now for only $99.99… Just joking it’s free.(If you’d still like to pay, just hit me up)

Instructions

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.

Materials:
1/2-inch, 3/16-inch and 1/8-inch foam core, preferably black
5-minute epoxy
Clay
Paint Edger attachment
15-foot telescoping pole
A few hundred LED throwies
Shrink Tube or electrical tape

Tools:
An exacto-knife
T-square/ruler

Step 1:
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).
