just want to showcase my custom Volumio build I have been working on in the past year. The case is milled from oak wood, the DAC is a ES9018K2M.
The amp ist based around an LM3886. I made the housing from sheet metal that I intentianally rusted on the outside.
I drew everything up in Onshape, the design is available here: https://cad.onshape.com/documents/5bde43b7c86d74c1d4da4259/w/d020c9d4c969d7b36d69b367/e/034110cee59e74d892b76194
I plan on putting all the details about it in my blog, just did not yet get around to do so.
