GoFlow is the world's first tDCS Kit.
The Collaborative Brain Experiment.

Transcranial direct-current stimulation (tDCS) is one of the coolest health/self improvement technologies available today. tDCS is a form of neurostimulation which uses a constant, low current delivered directly to the brain via small electrodes to affect brain function.
The US Army and DARPA both currently use tDCS devices to train snipers and drone pilots, and have recorded 2.5x increases in learning rates. This incredible phenomenon of increased learning has been documented by multiple clinical studies as well.
Today if you want a tDCS machine it's nearly impossible to find one for less than $600, and you need a prescription to order one. We wanted a simpler cheaper option. So we made our own kit, for ourselves and for all you body hackers out there. Pre-order yours!
Caution! Investigational Device. Federal (or United States) law limits device to investigational use.
We designed the GoFlow β1 to be the simplest, safest, easiest to build, transcranial direct-current stimulation (tDCS) device possible This tDCS kit can be assembled and configured in half an hour. This is the first ever standardized tDCS kit, and we are incredibly excited to share it with you all. Our design does everything possible to allow for safe consistent experimenting with tDCS. The kit is crazy easy to assemble, no soldering or burnt fingers required! The kit is not yet released, but we have shared our schematic so you can build your own.
Our plan for the weekend was to build a working device for each of us, and have as much fun as possible doing it. In all honesty, we were not focused on the business side of the project much at all. We did throw together a quick website and signup form right before the SW pitches, and worked up a business model to run with. Unsurprisingly, we didn’t kill it in the pitches. In fact we failed pretty hard. We weren’t too stressed though, we had our devices and we had a lot of fun building them.
What we didn’t anticipate was the outpouring of interest we received from tech community. More and more people were signing up for our email list. ExtremeTech, Make, and Technology Review gave us some great coverage. The coolest thing though was the individuals who reached out to us, asking for more information and sharing their projects with us. You guys are awesome, and have inspired us to take this weekend project, and turn it into a larger experiment.
It is important to note that we are not doctors, or trained neuroscientists. We are simply amateur scientists experimenting with tDCS, and how it affects personal performance. We feel that this is an important area of study, and our primary goal is to support motivated, intelligent experimenters in their efforts to safely test this technology.
tDCS has been around for decades in universities and hospitals around the world. However, most studies use their own self designed devices, resulting in data that is very hard to compare with other such studies.
We’d like to try a different approach. A standardized device, used by individual researchers. Amateur scientists who are willing to take the science forward faster than a few dozen disconnected researchers scattered around the globe.
We hope that our users will share their experiments and data, and help our community grow the understanding of tDCS as a whole.
