There are a multitude of issues that have lead to the creation and the need for this particular project. Generally, it is the prohibitive cost of most research level EEG's that create the need for a low cost demonstration model that can do more than just display the traces of the brain signals. There are two important driving factors in the needs and the design. The cost, meaning that it needs to have low cost per implementation and upkeep, and the functionality to do more than just record and playback electrode differential traces. For the former, many off the shelf components were selected based on their cost to functionality properties. For the latter, completely self built and designed devices were excluded, due to difficulty of implementation by students just learning about the subject and the general inflexibility of completely breadboard based designs, not to mention the variability of the parts and the ease at which it breaks down, even with the smallest of errors in the construction.
