I was finally able to give some attention to the VU Meter discussed back in January. The concept is based around the LM3916 chip produced by National Semiconductors. I still have to review the circuit and have another set of eyes sign off on it, but I’m fairly happy with how it stands. The circuit is designed to drive 10 5-LED arrays. The final package for everything is still being discussed but we (Adrian and I) are leaning towards a horizontally mounted wall display. One of the ideas that we are partial to is integrating RGB LEDs to produce a smooth fade of color from one end to the other. Concept sketches to come. For now enjoy some schematics and board layouts!
