Brain Computer Interfaces (BCI) based on Electroencephalography (EEG) allow for the monitoring and analysis of ongoing brain activity in real time. The signals measured by this technology can be used to control user interfaces without the requirement of the human motor system. This technology can benefit those with paralysis and other severe disabilities. As of now, the majority of BCI systems are currently large and immobile, and therefore impractical for use in everyday life outside of a lab. There are several components to a BCI system such as data acquisition, a classification system, as well as stimulation, all of which must be made portable to create a portable BCI. To address this problem, we would like to focus on making a portable stimulator that can interact, through wifi, with the BCIs that are monitoring brain activity. The stimulator will consist of flickering LEDs at predefined frequencies, with attention to luminescence (we don't want our LEDs to blind the user so it must be at the right intensity for each user) as well as controls to adjust the frequencies while maintaining signals timing. Our design goals are to make the stimulation for the BCI and EEG portable and be integrated wirelessly so that users are not confined to just a lab setting and that the system could be tested and used in different environments.

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.
