Now, the first thing I have to say in this post about how to overclock your brain with a straightforward 20-minute application of electrical current is DO NOT TRY THIS AT HOME. The long-term effects of TDCS are unknown, and if you mess up and put orders of magnitude more current through your brain than is typically used in TDCS, obviously, you could kill yourself.

Now that we have that out of the way, here’s how to try it at home.

GoFlow is a startup planning to offer TDCS kits for as little as $99.
Today if you want to buy a tDCS machine it’s nearly impossible to find one for less than $600, and you are typically required to have a prescription to order one. We wanted a simpler cheaper option. So we made one.
Air Force researchers were delighted recently to learn that they could cut [the time required to train drone pilots] in half by delivering a mild electrical current (two milliamperes of direct current for 30 minutes) to pilot’s brains during training sessions on video simulators. There is also evidence that TDCS can induce the state of creative nirvana known as “flow.”
When done correctly by a licensed physician, TDCS is safe enough that it’s already being used clinically to treat chronic pain. The GoFlow, on the other hand, appears to have been built by undergraduates. Given the (lack of) production values in their promotional video, I’m not all that reassured by the included testimonial from a neuroscience graduate student.
If you can’t wait for the GoFlow kids to get their act together, the Journal of Visual Experiments has an elaborate video tutorial demonstrating the finer points of TDCS administration.
