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

Featured Project

There is a drastic lack of networking infrastructure in unstable or remote areas, where businesses don’t think they can reliably recoup the large initial cost of construction. Our goal is to bring the internet to these areas. We will use a network of extremely affordable (<$20, made possible by IoT technology) solar-powered nodes that communicate via Wi-Fi with one another and personal devices, donated through organizations such as OLPC, creating an intranet. Each node covers an area approximately 600-800ft in every direction with 4MB/s access and 16GB of cached data, saving valuable bandwidth. Internal communication applications will be provided, minimizing expensive and slow global internet connections. Several solutions exist, but all have failed due to costs of over $200/node or the lack of networking capability.

To connect to the internet at large, a more powerful “server” may be added. This server hooks into the network like other nodes, but contains a cellular connection to connect to the global internet. Any device on the network will be able to access the web via the server’s connection, effectively spreading the cost of a single cellular data plan (which is too expensive for individuals in rural areas). The server also contains a continually-updated several-terabyte cache of educational data and programs, such as Wikipedia and Project Gutenberg. This data gives students and educators high-speed access to resources. Working in harmony, these two components foster economic growth and education, while significantly reducing the costs of adding future infrastructure.
