Hard Drive Persistence of Vision (HDPOV)

Step 7 Glue the LED Tape in Place

When affixing the LEDs, you shouldn't trust the sticker backing provided by the manufacturer. It just isn't strong enough. Get some super glue, and slowly glue the strip to the chamber wall, pressing firmly as you proceed. It's imperative the LEDs are affixed as straight and flush as possible, so work slowly and carefully.
