If people are interested in trying it out, you will be expected to read this guide to a sufficient level to be able to assess the risks involved and test the equipment to make sure it is safe to your satisfaction. No proof of safety is given and I'm just experimenting now.

Neurons are electric devices, they can be stimulated by electricity or electricity can make it easier or harder for them to fire. TDCS is the latter. So it works by having two electrodes and passing a very small current between them. The neurons near the anode (positive) have enhanced firing rates and those near the cathode are depressed (some experiments run this electrode in the shoulder to avoid depressing the brain).

It seems to have effects lasting 5 or so hours and seems to switch on protein production and help with long term memory formation and improving skills. Some people have tried to use it for treating depresssion. http://www.sciencecodex.com/new_depression_treatment_safe_and_effective-87382

Make sure you don't suffer from epilepsy or other neural stimulation problems.
