VU Meter Prototyped and Working

Last night we built a fully functional prototype of the circuit and it worked without any hitches. We limited the number of LEDs for testing; only 30 LEDs were used for output display versus the planned 50. We still need to properly configure the input by adding an amplifier stage and buffer. Some revisions were made to the design to make it easier to print. The traces were again widened and the ground plane was touched up. These images will be included in the next post, which will come when we finalize and have the proto circuit working to music. We are still debating the final look of the actual display and have several different versions. Each version has its place in a different environment. I will try to include some of these sketches in the upcoming photo dump.
