I was responsible for the structural and mechanical implementation of the project since my strengths lie far more in this area than in writing computer code. Additionally, unlike Hanna, I have the necessary resources at home to craft. | I was responsible for the structural and mechanical implementation of the project since my strengths lie far more in this area than in writing computer code.

We needed a mount that would allow the servo motors to hover above the guitar strings so they could pluck them individually. The servo motors had to be positioned at a certain distance from each other to avoid interfering with one another when striking the strings. We had already identified this issue through a cardboard prototype. Since guitar picks were to be attached to the motors, increasing the radius of the strike, it made sense to always leave two strings between those being played. | We needed a mount that would allow the servo motors to hover above the guitar strings so they could pluck them individually.

Since I couldn’t guarantee millimeter-precise construction, and factors like the surface, variations in the way the picks were attached, or different motor models could create height differences, it was necessary to allow for fine adjustments to the height of the mount. For this, I used special adjustment screws that allow the height of the mounting beams to be individually adjusted on both sides. Unlike regular screws, these have two types of threads: the upper thread remains fixed in the wood, while the lower thread can be screwed in and out like a standard screw. This enables precise millimeter-level height adjustments to fit the conditions. | |||
Additionally, the sensors had to be connected to the breadboard. To do this, I soldered cables—each consisting of three wires—of sufficient length to each of the six sensors. I then soldered a connector to each wire to facilitate easy attachment to the breadboard. | Additionally, the sensors had to be connected to the breadboard.
