Here is the slideware we used for our workshop in the Biohacking Village @ Defcon 27. We covered the operation and calibration of the tDCS devices that were handed out as well as uses, and the 10/20 mapping system.

What is tDCS?


Transcranial Direct Current Stimulation

Wikipedia very simply defines tDCS as, “a form of neuromodulation that uses constant, low direct current delivered via electrodes on the head.” But let’s explore that further. What does that mean? Essentially, the concept of tDCS is this: by applying voltage to specific neuronal areas and…

TENs, Amrex, DIY Sponge Electrodes

An important component of tDCS and one that might be overlooked by DIYers is the electrode. Folks looking to explore brain stimulation using a few electrical components and a nine volt battery, might forego the $25 — $40 cost of a couple 2 inch Amrex electrodes in favor of something…

These short blurbs are in conjunction with our tDCS workshop at the Defcon-25 conference in Las Vegas 2017, Biohacking Village .

What should you expect to feel and experience when you try tDCS? Electrical buzzing, euphoria, instant blossoming of cognition?

As far as the moment by moment experience, the reality…
