As mentioned in a previous post, I'm going to attempt to systematically document my experimentation with tDCS. Because I'm only an individual, that is, without a lab, test subjects, funding for experimentation, I don't have the ability to create a control group to compare results to. To work around this, I can only run tests on myself, before tDCS sessions and after (making the note any "pre" testing sessions need to have happened long enough the last session such that any effect had long since worn off).
Enter Cambridge Brain Sciences, a site which offers, "scientifically proven tools for the assessment of cognitive function over the web." Running the various tests several times ought to establish rough control. While there will be some impact on latter tests due to a bias from practice, familiarity, results should become somewhat consistent. Perhaps someone with a better handle on statistics knows a more straight forward method than this, but if tDCS sessions are indeed making a measurable impact, such should be observable by comparing control results with post-session tests.
