Giga Meter ver4 is a return to the build of my first version with a lot of improvement. The antennas feature bright blue LEDs that pulse and flash with the color changing LED behind the main viewscreen. Under the dome are alternating green and amber lights that chase in a clockwise pattern. All of the lights run off of a 9volt battery that is accessed via a panel on the bottom. Weathering has been done to make the scanner look used and abused.
