Over the new year my father and I made a prototype surface mount circuit board using a CNC engraving machine. The assembled DAC works very well and we might turn this into a small product for mobile listening. Here are some pics of the assembled prototype.

Ask me anything about this project or equipment, and I'll do my best to answer.
