Inspired by some of the PCB art, this is a front panel project for the Mutable Instruments Clouds Eurorack module.

Original, purple Oshpark, black and white variation.

The art piece is from the Hackaday.com article, Neurons a Hacker Perspective by Joe Kim. Here is Joe's talk at the Superconference about balancing art and technology.

For most PCB art there are 4-5 colors available depending on which color of solder mask is used. Gold, silver, or copper, solder mask light + dark color, white or black screen print. You can also add an optional silver color to a gold or copper layer with the paste layer.

For the first board I wanted to use Oshpark so I tried a purple color layout. The layers are separated in Illustrator.

First layer is copper, second is where not to apply solder mask, and last is the screen print.
