LED rings

For a school project we needed to make up something original to add to an amp we were designing. The thing we choose to design was an led ring to be put around each potentiometer.

The ring will consist of sixteen 3mm leds, controlled by two 74hc595 shift registers. In the final version we will use double gang potentiometers, so we can measure it’s position without disturbing the audio signal going through it. Because it has to be really small we will use smd shift registers, and smd resistors. This will probably be a pain to solder, but we’ll see how it comes along.
