This was a totally scratch-built commission of the Star Trek: Next Generation Starfleet/Combadge-symbol to hang on a wall. It measures 16"x16", is built totally from scratch out of styrene, EVA-foam, PVC-sheeting & aluminum. I also implemented a 16-color LED remote-lighting assembly inside, that activates a light-activated sound-module that plays the 2-min. Next Generation theme-song when the LEDs are turned-on. The outer-symbol is magnetically-attached to the base using 2 powerful quarter-sized rare-earth magnets on the base and badge-bracket, and easily pops-off to change the batteries in the electronics inside. Weighs about 1lb. total and has a single picture-hook on back for easy wall-mounting. Demo-video of the different colors, effects & sound below.
