I’m very happy with the outcome of my object and excited about moving forward with some of these techniques, having learned what I have from this process.
There was an initial setback after covering the area in copper paint with the foolish idea that I would be able to gouge out channels in the grooves to establish the circuit. After deciding this would be impossible I opted instead to sand off the top using the copper in the grooves as the active component.
From there forward, things seemed to work quite well and I had an interesting time trying to craft a piece of generate code to match the style and type of interaction with the object.
