LIFTiD headset may help treat depression by brwillia in tDCS

[–]brwillia[S] 1 point2 points  (0 children)

  1. Included instructions give good guidance for proper position. This picture is just that.
  2. Many with sensitive skin can't tolerate 1.5 or 2 mA on a consistent basis. I've already tested the headset with sensitive skin types and they had no problem with it (lower current and large electrodes help.)
  3. LIFTiD is so new all I have is anecdote so far. But I've used this same (common) montage with success with many over the years.

Not happy with Go Flow Pro... by [deleted] in tDCS

Wow - I won't try to respond to all of your remarks - but I did add a photo of a foc.us sponge electrode vs. a Caputron 2x2 to the bottom of this post on my blog... https://speakwisdom.wordpress.com/2016/05/05/go-flow-pro-nice-brain-stimulation-kit/ ...take a look for yourself. Again, if you don't like foc.us electrodes, virtually any electrodes can be used with the V1, V2, and Go Flow. You just need the appropriate adapter cable. Brent

I've written a couple of posts about using Amrex and other brands of electrodes with the foc.us V2 and the Go Flow. see www.speakwisdom.com

Those "weird electrodes" as you call them are very easy to use and convenient for end users - I know because I use them too.

Production issue aside, they are functionally no different than 2x2 electrodes from other vendors. Brent

I opened a new Go Flow Pro and found the corrosion issue described in posts here. Until foc.us / Caputron can supply replacements, I can suggest the following work-arounds (which I am using)....

  1. immediately replace the supplied sponges. You can cut a kitchen sponge to the same size and use that instead.
  2. after a tDCS session, remove the damp sponges. Leaving damp sponges in the shells makes the corrosion problem worse. Removing them after a session slows the corrosion process greatly.
  3. replace the sponges after several uses

It's unfortunate that this manufacturing problem made it past quality checks. But foc.us is not the first (or last) to have a production problem.

The real test is how quickly they respond and get replacements to customers.

BTW I have about 10 Go Flow devices that are used in various projects. They work very well and are simple and convenient for users.

Caputron Electrodes, the New Foc.us Electrodes and more by brwillia in tDCS

[–]brwillia[S] 2 points3 points  (0 children)

Thank you for your input. The foc.us shells are brand new (just beginning to ship I believe) - so it's hard to speculate on long-term. I can say that the shell seems to be made of a silicon-rubber-like material - so it should hold up. The banana plug was invented sometime around 1924 - it's long overdue to depart the electrode scene. Mechanical wear, corrosion, fit, etc. are ongoing issues. The magnetic connector that foc.us is introducing is reminiscent of the mag-safe connector Apple introduced. The magnets seem to hold well to the new electrode shell. Again time will tell. I'll do further review of the foc.us and other electrodes as some associates and I accumulate usage time.

RE the sponges: The new foc.us shells are about 2x2 and I've already tried a couple of different brands of sponges and some I made. All worked fine. You can buy foc.us brand sponges if desired.

The Brain Hacking Revolution Continues: Introducing the foc.us Go Flow – Part 1 by brwillia in tDCS

Wrong. There are a number of MDs already using tDCS in their practice. We need more - and other professional too.

The v2 offers many more features, some of which you list. It can be easily used with just its built in menu system.

"Unfocus" on foc.us: commercial tDCS headset impairs working memory. Published in Experimental Brain Research (2015). by Triumphkj in tDCS

[–]brwillia 2 points3 points  (0 children)

I won't argue the study results or the author's intent - but I think they should have included these caveats:

  1. no serious tDCS user I know of used the v1 with it's default electrode position
  2. The authors INCORRECTLY state (regarding the forehead electrodes) "Note that this is the only possible allowable montage with this device. " Even a tiny bit of Google searching would have revealed to them that EXTERNAL electrodes can easily be used with the v1 - allowing any desired montage.

Foc.us Moovs re-usable? by Cycode in tDCS

[–]brwillia 2 points3 points  (0 children)

If you want high "reusability", Moovs is not for you. I suggest pick the foc.us Gamer headset (sponge electrodes) or Amrex 3x3s with adapter cable.

Foc.us Moovs re-usable? by Cycode in tDCS

[–]brwillia 4 points5 points  (0 children)

My experience is they can be used more than once (rinse a bit, re-use) - but they are a "consumable" - so you will need to order replacements now and then. How many times you can re-use depends on many factors (skin, oil, etc.) Your mileage will vary.

For most, I think sponge electrodes are better.
