This is anecdotal, and I have not followed rigorously the experimental protocols of any of the papers I have cited, nor have I subjected myself to tests of retention, calculation or reaction time. Nevertheless, I believe the device has enabled me to achieve a higher karma score on Hacker News. I have authored a paper on mathematical logic after a period of previously drafting notes, and have had success with the integration of large-scale multi-disciplinary environmental systems models. Finally I believe the cognitive gains my unlicensed, home-made DIY tDCS device have enabled are sufficient to overcome the bias that otherwise would have left me unemployed (cf. http://www.nytimes.com/2012/01/29/us/bay-area-technology-pro...).

To be honest, I wish you had disconnected the device before writing your original comment, because it is a bit hard to follow :-)

But really, if you are capable of building such a device, wouldn't that make you very employable to begin with?

You must live in some crazy world where people are employed for their abilities.

It sounds like you have to be wearing the device in order to benefit from it. Do you work from home while "plugged in"? Or, can you just use it while thinking about a tough problem or while learning something new and then when it's turned off still have the insights/new knowledge you gained?

for me is effect noticable after 6hours most powerfull is hour after aplicaton

1 stuty found residual effect after month

When did you build the device? It seems like you must have known about this for some time since you say it helped you get a job. Meanwhile, the article on Oxford's site was just posted today. How did you find out about it?

I started reading the literature on tDCS in November, 2010. There have been articles in the popular science press on tDCS at least since then. I was motivated to build the device after reading an article in Scientific American from November 2011, one year later: http://www.scientificamerican.com/article.cfm?id=amping-up-b... And now I must get back to work...

i iknow tDCS about 4years and test it about 3 , but eraly test it vas only 9volt batery , potentiomether(I must regulate current manualy) and 2 electrode from watch cover
