# Conducting brain stimulation at home

(Asked by: username_0 on 2016-01-20)

Given articles like [this](https://cosmosmagazine.com/life-sciences/buzz-around-brain-stimulation), and their associated research {1}, I am developing an interest in transcranial magnetic stimulation (TMS), transcranial direct current stimulation (tDCS), and other forms of brain stimulation as they appear like they may have. I might be interested in trying it at home.

As a result I would like ask for evidence to help me answer one or more of the following questions:

1. What is the best headset for brain stimulation that a normal person can buy or build? I am aware of [these](http://www.foc.us/), but would like the opinion of an expert.
2. What are the best online communities, or sources of information for conducting brain stimulation at home?
3. How should I engage in brain stimulation at home? A guide, or link to one would be appreciated
4. Is it safe to conduction brain stimulation at home? If there is evidence that one type of brain stimulation, and/or headset is safe then please provide evidence of this.
