Robin is the founder of Caputron which is a distributor of tDCS and other TES devices. Here he demonstrates the Activadose II tDCS device. For reasons mentioned elsewhere on the blog, this is the device I recommend (this is an FDA approved – for Iontophoresis – device. I’d suggest the 2mA model with the 3×3 sponge set – this is closest to what most research studies use). Caputron provides DIYtDCS readers a generous discount (I also earn a referral fee) when you use discount code ‘diytdcs’ at checkout (for any product offered by Caputron). I interviewed Robin back in 2015 when he was first getting started. Check out that post here.
Robin at Caputron dropped me a note to let me know they are now carrying the Foc.us V2 device. Purchased alone, it does not include electrodes, but there is an option to add their ‘starter kit’ which includes the Caputron Universal Strap, Caputron Banana Adapter Cable for Focus Device, and Choice of 2×2 or 3×3 Electrodes. (Use diytdcs at checkout for generous discount). Foc.us V2 Device at Caputron.
If what attracted you to tDCS is all the news (and hype) around the possible benefits, cognitive and otherwise, that tDCS may provide, then I recommend the Foc.us V2 device. It’s had a thorough going over, and apart from the (then included) electrodes, proved to be an amazing piece of gear. tDCS, tACS, tRNS, tPCS in a single sub $300 unit with a software interface!
Elsewhere on the blog I’ve stated that I recommend the ActivaDose ll device. This is an FDA approved device – it’s NOT FDA approved for tDCS – it’s approval is for use as an Iontophoresis device. The point is that the electronics and workmanship have attained an FDA level of approval. It’s simple and straightforward to use.
The only reason I haven’t recommended other tDCS devices on the market is because I’m not in a position to analyze the quality of their workmanship myself. I recommend the Activadose ll because people looking to experiment with tDCS for the treatment of depression can’t be assumed to have a toolset for determining the mechanical workmanship of an electrical device they’re going to be attaching to their heads! The Activadose ll, an FDA approved device, at least assures the buyer the device itself is of high quality. It’s also more likely to retain some resale value in the event someone decides later on to sell it.
I recommend the Foc.us V2 because of it’s variety of stimulation modes. Folks who are sophisticated enough about neurostimulation to be experimenting with cognitive enhancement would obviously benefit from having the option to test other forms of stimulation that frequently come up in the scientific literature.
When you use code diytdcs at checkout at Caputron you get a discount, and I get a small commission.
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.
Excellent article traces the rise in tDCS interest. Includes many of the key players and links to important research papers. Do DIY Brain-Booster Devices Work?

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.
[Did you just pop back for the Caputron promo code? It’s ‘diytdcs’ without the quotes.]
Robin Azzam is the founder of Caputron. While pursuing a Masters in medical engineering at New York City College, Robin realized there was a need in the research community for a place to source brain stimulation supplies. Shortly after leaving a position in product development at Soterix Medical, Robin and a few friends set up Caputron with the intention of becoming a ‘one stop shop’ for all things related to brain stimulation. His time at Soterix, working alongside Marom Bikson, led to the sort of relationships that allowed Caputron to become a distributor for high-end products like Soterix HD-tDCS and Neurosoft’s TMS devices. But Caputron also began to carry a large selection of electrodes, cables, straps and stimulation-related accessories. Caputron is now developing their own products, and hope to have their own research-grade home DC current device on the market by the end of the year. They recently began selling their mindGear device which I will cover in detail in the near future.
What DIYtDCS readers will likely find most exciting is Caputron’s ActivaDose II Starter Kit. This is the FDA cleared iontopheresis device widely used ‘off label’ for tDCS. It is the device used by two of my previous podcast guests, Dr. Jim Fugedy (for treating depression) and, (at the time) Michael Weisend for research. But Caputron has customized the included accessory package making it tDCS-friendly right out of the box.
In the three years I’ve been running the blog I’ve not previously felt comfortable recommending any specific tDCS device (mostly due to my own ignorance of electronics). I’ve either had doubts about the device itself or not had confidence in the vendor’s customer support. But based on my own experience with the ActivaDose products, the fact that it’s an ‘FDA cleared’ device, and also that it’s coming from Robin and his team, I feel, finally, that we have a product/vendor you could recommend your Mother to. (Assuming she does her homework!)
To that extent, I asked for, and Robin agreed to, a discount on all Caputron products for DIYtDCS readers. Simply plug the promo code ‘diytdcs’ (without quotation marks) into the Voucher window at checkout for a generous discount.
Here’s our interview. Your feedback is welcomed!
Note that I do have a relationship with Caputron. When you make a purchase from their site using promo code diytdcs (add to ‘voucher’ box, any item on their site) you receive a discount and I receive an equivalent amount in exchange for providing them a visitor. I have been offered similar relationships with various vendors, but Caputron was the first I felt comfortable partnering with, primarily because their customer support and communication has been outstanding. But also because they carry the ActivaDose Iontophoresis Device which is an FDA approved device (approved for iontophoresis, not tDCS, but the point is that the components and quality are medical grade.) Bundled with the Caputron electrode kit, this is an excellent choice for anyone looking to experiment with tDCS. This is the only device I am personally recommending at this time.
That said, Caputron has just started carrying other DIY DTC (Direct To Consumer) tDCS devices. They announced yesterday that they now carry Super Specific Devices tDCS Stimulator
the Apex Type A device, and…
the Cognitive Kit.
Caputron is rapidly becoming the primary distributor of all things brain stimulation. This puts them in the unique position of being able to bundle appropriate electrodes and cables with the various devices they carry.
But Caputron are also manufacturers and we can look forward to interesting tDCS related products of their own coming soon.
