Circuit Progress and Material Prep

Since my cardboard mockup, I have built the circuitry for the project on a breadboard as seen in the first image. As you can see below, it got very chaotic. I was able to test each of the four two-input-one-output trios with a Honeytone amp and confirm they work. I chose to plug the speaker into the circuit at the second input instead of the output which results in a triangle wave as opposed to a square wave. This gives a smoother, warmer, more consistent tone.

Next, I began to solder my circuit onto a solderable breadboard and have connected all of it except the photoresistors, which I will need to attach to long wires so that they can be placed far from my breadboard.

The next step for me is to construct my wooden cross structure. I have sourced a plank that will need to be sawed in half longways, and notches will be cut so that the pieces can fit together.
