The β1 comes with everything you need to built your own tDCS. No soldering, no worrying about frying your brain, no stress. A purposefully simple device, it is easy to setup and use. We are in the design an prototyping phase right now, and the final design is yet to be determined.

I'd be very willing to try this out once it has been demonstrated that there is, indeed, no need to worry about frying your brain.
