Dial One

“Dial One” is the first piece of electronic equipment I have made that I am officially considering a piece of art, and am offering for sale as such.

It was conceived while I was on the Purification Rundown and completed in this form just yesterday. Like most art concepts – and most electronic equipment – there are many possible ways to turn the concept into reality, and many possible “variations on the theme,” or parts of the design that could be made differently. This is the first working prototype of this concept – a dial. On the circular screen, a pattern of lights rotates as an input signal varies between zero and five volts.

Dial One has all the basic features I imagined for this type of piece. With 4 knobs, the user can vary the pattern of lights. There is a sliding control for testing the effect, and a connector for an external sensor which would provide some varying signal (such as sound level or distance of nearest object). The display can be made totally dark or rather bright.

This particular prototype is housed in a black aluminum enclosure originally made for a vacuum tube voltmeter. The display features white, red and orange LEDs. Power is supplied through a standard computer-type power cord inserted in the rear.

The circuitry is all hard-wired – no programmed elements. This was the original concept for this piece, so I kept it that way. In fact, I could not immediately think of an easy way to achieve this same effect using a micro-controller. I plan to return to this concept again before too long and explore some different ways to implement it.
