TDCS Electrode casing for OpenBCI

We are a team of engineers, neurobiologist’s and psychologists working on a new user-friendly, plug 'n’ play tDCS device. Until now, we have been testing different electrode-placements and types, using the awesome OpenBCI (http://openbci.com/) ULTRACORTEX frame.
We love OpenBCI and the opensource-strategy so we put our tDCS electrode casing up here. It is an humble contribution, that allows hackers to get started with the tDCS right away using the ULTRACORTEX, but we hope to share much more the coming weeks. We are crossing our fingers that OpenBCI reach their stretch goal with their KickStarter campaign and get to develop the tDCS shield. For those who can't wait: here you go!

The casing fits snugly into the octabolts (see picture for assembly-instructions) and can rotate freely in order to adapt to different head-shapes and sizes.
