Update 7/25/16 Caputron just announced their Banana Adapter for Focus Devices which facilitates use of Focus with Amrex or Caputron electrodes.
Caputron will be handling all Customer Support on GoFlow devices purchased through their site. At this time they have over 100 units in stock. If you’re not familiar with Caputron please check out my interview with founder Robin Azzam. Caputron has extended their discount to DIYtDCS readers for all products on their site, including the GoFlow. Use voucher code ‘diytdcs’ (without the quotation marks) for a generous discount.
New Go Flow Pro package.
Robin at Caputron sends word of their new ‘exclusively from Caputron’ ActivaDose 29V 2mA max Iontophoresis device. My one caveat with the ActivaDose had been the potential for user error in choosing a 4mA setting (rather than the 1 or 2mA setting traditionally used in tDCS research). This new device removes that possibility. This is the device you could confidently show your Mom how to use. The new version maintains the ActivaDose FDA approval for iontophoresis. This new version becomes the device I can recommend in all confidence, also because Caputron stands behind all the products they offer.
Readers of the blog get a generous discount on this, or any other (including GoFlow) device purchased at Caputron using promo code diytdcs at checkout.
Focus has posted a new page on their site which directs new users to show caution in their use of DIY tDCS. Focus goes so far as to caution people under the age of 18 not to try it.
If you are under 18 you should stop here. tDCS is not suitable for children and should not be used. This is because your brain is still developing and you don’t need to mess with its neuroplasticity.
The page goes on to list the known risks and a few benefits. Interestingly, it does not mention depression. I would have to imagine due to the possibility of crossing that nebulous regulatory line around ‘medical devices’.
Focus is, as I understand it, in the midst of fulfilling orders for their GoFlow device. You can read a full review of the GoFlow on SpeakWisdom, the (primarily) tDCS-related site authored by Dr. Brent Williams. Go Flow Pro, Nice Brain Stimulation Kit!
New Go Flow Pro package.
Just to reiterate, I have no association with GoFlow, just sharing the news.
Sorry for the long hiatus, we know we’ve been quite way too long.
We wanted to let you know that we are still working on the GoFlow project, and give you a hint or two of whats coming next.
We’ve been taking the last two months to “science up” and run more extended self tests. Any risk we can mitigate by taking the time to become more informed and test our device thoroughly is more than worth the delay from our end.
We have been getting tons of feedback to the contrary from some of you, and trust us we empathize. We did build one and use it on ourselves with very minimal research and testing. We can’t in good faith do that to our community. We say that fully appreciating the irony there..
We are continuing the development process as fast as our limited resources and time allow, and we will be much more communicative as we continue.
Stay tuned for updates and always feel free to email us with questions!
The GoFlow Team
I’m on the GoFlow mailing list and received this update this morning.
Hello all you beautiful peoples,
We’ve been silent for a few weeks now, and it’s time to bring you all up to speed on the GoFlow project again. (The diy tDCS kit if you’ve forgotten) We have officially been rejected from Kickstarter, and are delaying the production of our devices for a short while.
However we do have some progress to share with you all, and enough info to get anyone who is interested a decent way along in building your own. See below.
While it’s too bad that we are not able to rock a Kickstarter campaign, we move forward. During the process of getting the project ready for crowd funding we ran into a few legality concerns that probably would have stopped us from launching as quickly as we had planned, even if we were approved for Kickstarter.
We are taking the time to investigate these concerns now before we do something to prematurely sink our metaphorical ship. If any of you have any experience or thoughts that you’d like to share, we would love to hear from you.
Out main obstacles right now are:
- FDA classification concerns
- and subsequently approval
We’d love to hear from any of you that have experience with working with, and or around, the FDA. We’re talking to a few specialists and mentors now, but we are interested in leveraging the collective knowledge of you all as well.
We will keep you all updated to our progress as we move forward.

Petr dropped me a line with an update on what brmlab has been up to lately. Wow! Check out the photo album. Very interesting collection of crew and gadgets. Here he is with an early version of his tDCS device.
He also pointed me to the focus. I don’t know how I’d missed it. Unfortunately (for me)…
Due to F.D.A. requirements the focus v1 is not currently available for sale in the United States. If you live in the U.S. and would like to buy a focus device, please pre-register. If there is sufficient demand from U.S. customers we will seek the necessary certification.
I think we can expect a lot of that. But how cool! You can sign up for ‘priority access’ on their site.
One of the things Petr and I discussed is objective testing for use in determining whether or not a tDCS device is actually doing anything. Petr came up with some great links. Both PEBL Psychological Test Battery and Brain Workshop – a Dual N-Back game, seem to be tests you download to your own computer. But I’ve just spent the last 20 minutes doing tests on a site called Quantified Mind. Except for the Google (only) login, it’s about perfect. A nice collection of tests and the results are collected very nicely into a statistics page that associates with your account. Cool! [Update 5/25/12] Another interesting candidate for measuring effectiveness. Lumosity research partners include Stanford and Harvard. A very basic reaction time test, HumanBenchMark.com.
Petr also mentioned that he corresponded with the GoFlow people and they are going to set up a wiki. In their recent email they announced they were a little bit behind and were waiting to hear back from Kickstarter. But that whether or not they get Kickstarter approval they’ll be moving forward soon.
All for now.
A kit already!
tDCS is one of the coolest pieces of health/ self improvement technology available today. 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 is achieved through a very simple device called a tDCS machine.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. Then, because we’re all egalitarian like, we thought others might want one too.The GoFlow β1 is a full kit of all the parts and plans you need to build your own tDCS device. $99 will get you one of the first β1’s and will help us develop β2!
And some background om the GoFlow from SFGate.com March 2012
“When you look at the brainwave patterns created by these machines, they are very similar to those a pro athlete would experience when they are in that state of flow,” Sornson says.
It should be noted that Sornson studies marketing and not neuroscience, and the rest of his crew specialize in software and website design. “This machine will be designed for people interested in experimental use,” Sornson says.

Even at $99, the GoFlow kit is fairly expensive. Just so you understand just how simple tDCS is, all you have to do is pass 9V at 2mA through your scalp for 30 minutes. To do this, you need a battery, some electrodes, a resistor, and if you’re feeling snazzy (and safe) a current regulator. To be fair, for your $99, GoFlow will give you a plastic housing and provide a potentiometer — presumably so you can find the right voltage for your brain. You also need to know where to place the electrodes on your scalp, to boost the right area of your brain. Judging by the picture on the right, GoFlow will provide a map of the various regions.
