In the spirit of fairness, I’m posting this musician’s experience of using the Halo Sport for guitar training. Unlike Mario and his piano experience, this fellow, TomboLP, ultimately found no added benefit, though in earlier videos (this is the part 5 of 5) he was excited by what he assumed were positive results.
This is the last video in my test of the Halo Sport. As I didn’t reach the goals I set for myself in the time allotted and feel that there were no gains that couldn’t be otherwise explained by practice, I have now returned the headset. Even though the product didn’t work out for me, I will say that the return process was very straightforward and hassle-free.
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.

I do hope to understand this better. Is it just that he was so impressed with his own Halo Sport experience that he was motivated to tell the world about it? Is it that Mario is a YouTube content creator and knew this would be compelling content? I will update the post as I learn more.
And here is the video Mario made in November, 2016 where he describes the impact using Halo Sport had on his piano playing.
Hey Mario, If you’re reading this drop me a line, I’d like to talk to you.
Insurers are starting to cover TMS for depression (after determining that SSRIs or other medications aren’t working for the patient). A full course, 24-36 treatments, of TMS can cost well over $10k. Though this is purely conjecture on my part, one way tDCS might make it into the mainstream is as a method to ‘top up’ post-TMS treatment as effects begin to fade.

As the number of people suffering from depression rises, doctors are looking for new, more targeted ways to treat it. One approach used by doctors at UCLA and a handful of other centers nationwide is to beam magnetic pulses deep into patients’ brains, a therapy known as transcranial magnetic stimulation (TMS). The therapy is time-consuming, and only a few hospitals or clinics offer it, but its ability to work in a fundamentally different way from medications is also what makes it so promising for people not helped by drugs.
Wow! No less than Hank Green ( of the Vlog Brothers) covering tDCS on his SciShow Psych! He sounds a little skeptical! So we have that in common. I pretty much agree with Hank’s perspective, just a couple of thoughts I’d like to share.
Most companies (but not all) know better than to make claims about tDCS. They know they have to be careful making claims of benefits. So where you see a company making a claim, they are most likely basing the claim on legit science. But are the benefits replicable in your situation? Hank refers to the (science) literature as ‘messy’ and he’s right, with different labs coming to opposite conclusions using basically the same experiment protocols.
Hank characterizes the basic function of tDCS as being a training session for neurons. Over time, with repeated stimulation, those neurons will start to fire more. While this is a legitimate description of the approach some research takes, I think a better way to think of it is that tDCS makes it easier for neurons that are already inclined to fire, to do so. As in- you’re focused on a “Where’s Waldo” task, and with the proper stimulation, the task is easier to do, because the targeted neurons have less resistance to firing.
Mike Weisend – Treating the Brain from the Outside We met Michael Weisend back in podcast #4 (March 2013!) and have been following along ever since. In this interview Mike discusses what he’s been up to at Rio Grande Neurosciences. What caught my ear especially were the discussion around ‘closed-loop TES’, where EEG information informs when and where to stimulate with TES. Also, his discussion of personalized disposable bio-degradeable electrodes was interesting. Mike closes the interview with an invitation to anyone knowing how to engineer an ‘EEG amplifier’ that would allow for the separation of EEG data and active TES stimulation, to contact him. (mike.weisend [theAtSign] riograndeneurosciences.com). Kudos to Richard Jacobs for an interesting interview.
In the third section of his talk (around 30 minute mark), Dr. McConnell discusses an experiment they are working on that uses EEG to monitor sleep, and according to their protocol, turn on a TES device (tACS-like) in order to induce slow wave EEG activity. The practical application is improved memory consolidation in Alzheimer’s patients. Very interesting!

Finnish company Sooma manufactures and supports a tDCS device for the treatment of depression (in Europe). They recently added clearance to treat pain in Canada, and I would assume, are aggressively working towards clearing their device for the treatment of depression in Canada and the U.S.
I would recommend muting the sound (captioned so not necessary) in these next two.
If you follow the blog you’ll know I’m not savvy enough in the ways of electronics to know a well-constructed DIY circuit when I see it. I’ve generally depended on the Reddit crowd to sort through the pros and cons of DIY tDCS circuit design. Now that there are a handful of professionally developed and readily available devices on the market, I’m not seeing as many DIY projects, but here’s a couple that popped up on Youtube in the last week or so.
According to Instructables/reddit user quicksilv3rflash…
This device can be used for any kind of human electrical stimulation, such as tDCS, tACS, tRNS, or tVNS. Its hardware, when properly constructed and tested, limits output current such that -2.1mA < output_current < +2.1mA , based on the 2mA safety limit recommended in these published guidelines.
Lew Lim, the founder and CEO of VieLight is seen explaining the device in the video.
The technology is called transcranial and intranasal photobiomodulation (PBM). Initial, small-scale results, are promising.
Five people, with mild to moderate Alzheimer’s, used the headsets every day for 12 weeks. The headset frame, with four different LED cluster-heads and an LED that clips to the inside of the nostril, was turned on for 15 minutes a day.
After the three months, neuroscientists noticed some patients, who were not able to speak in full sentences, could now put sentences together. Patients also experienced improved sleep and reduced wandering.
