Rotary Volume Controller

A seven-channel desktop audio controller built as a birthday gift, with a machined aluminum enclosure and engraved application icons.

Seven rotary potentiometers provide physical control over individual Windows audio channels. I designed and machined the enclosure, engraved the icon set, wired the electronics, and configured the controller around the open-source deej desktop client.
