| Problem: One issue that can come up with playing guitar on stage is wanting to switch guitar pedals on and off while playing. If a guitarist wants to change the effects on their guitar as they are playing, they would either have to have their pedalboard on stage, or would need someone else controlling which pedals are turned on and off. Solution Our solution to this problem is a motion sensing attachment that can clip on to the bottom of the guitar. The attachment will project a lighting display on the ground, indicating which pedals’ effects are currently active, as well as using motion sensors to detect when the guitarist kicks near each light. The attachment is connected wirelessly to a custom routing box, which routes the signal through the connected pedals, allowing the guitarist on stage to control which pedals’ effects are active at any given time. Solution Components Subsystem 1: Lighting This subsystem will have to display different colored lights on the ground from the guitar. The entirety of the device will have to be angled from the guitar so that it can shine directly to the ground. One color of light will indicate the effect is active, and another will indicate that it is inactive. Subsystem 2: Motion Sensor This subsystem will be responsible for delivering user inputs. When someone steps on a light, that light will turn off and the pedal effect associated with that light will activate. When another light is stepped on, the pedals’ effects will combine, as they ordinarily would while using a standard pedal setup. In order to remove a special effect, you need to step in that area again. Subsystem 3: Pedal Connection Box In order to use multiple effects, we need to use foot pedals that are turned on and connected to the box. In a normal guitar pedal arrangement the pedals are connected in series, so the box will route the audio signal in series through whichever pedals are designated by the sensing system. The box will have a wireless receiver that takes in data on which pedals should be activated, and use it to route the signal in and out of the connected pedals. Criterion For Success Describe high-level goals that your project needs to achieve to be effective. These goals need to be clearly testable and not subjective. In order for our project to be considered a success, the guitarist should be able to switch between their pedals as they like despite being away from the pedal board. The criterion for this to occur would be: 1) The kick/step motion effectively toggles on/off desired pedals 2) The lights correspond with pedals correctly 3) Pedal connection box correctly routes the signal to go through the desired pedals |
