A breadcrumb trail of project notes
I completed the second version of my blue flower. This time instead of making a circuit board I etched a copper sheet directly leaving me bare copper circuit traces which could then be bent into shape. Soldering to the copper was difficult because of the large mass of copper sucking the heat away. It was important for me to make a circuit that is it’s own structure. There is an efficiency of design in nature — nothing is wasted and no parts of the structure are without purpose. This flower is an effort to design according to those lines.
The component layout was designed in Eagle and printed out. The petals were then drawn by hand over the component pads, scanned, and cleaned up in Photoshop. The finished layout was laser printed and transferred to copper sheet, which was etched with ferric chloride and cleaned with laquer thinner.
