The autorouting function was used again to make the traces thicker. A balance was struck between making a working design and getting the thickest lines and widest clearances. Wider traces seemed like a logical choice when the thin traces were getting skewed in the transfer process.
The method for transferring the toner from the paper to the copper needed some revision. This time, after heating the transfer paper, it was clamped under a clipboard to a stone countertop and allowed to cool. Using the clamps greatly increased the reliability of the transfers.
A recipe for a new etching solution was explored. This solution used came from an Instructable which detailed the two-ingredient recipe. If you read the recipe and look at the photo below, you can see that the proportions have been reversed. There should be two parts H2O2 (hydrogen peroxide) to one part HCl (hydrochloric acid). Don't follow the proportions in the photo below.
