This is the page of the Brain Hackers aka the Neurohacking/Neuromodulation London Hackspace Group. We do experiments and play around with kits to measure and alter brain activity in a non-invasive way and develop novel accessible neurostimulation means accompanied by real time measurement and feedback. Some of us are trained neuroscientists or electronics engineers, others are hobbyists. All friendly and interested people are welcome to volunteer and participate in trials, but everything is obviously at your own risk (where such risk may exist).

DIY news:

- the current ICIBCI meeting is https://www.meetup.com/NeuroTechLDN/events/245406475/# The page for the project is https://icibici.github.io/site/ and Git is at https://github.com/icibici/Android-diagnostic-app It works, and if anyone wants a kit to try, improve, and develop apps, please contact Colin Rowat <c.rowat@espero.org.uk>

We are now in the process of organizing and starting work on a few specific projects from the Project Ideas. More update on this in the coming weeks.


List of measurement and stimulation kit available by different members of the group:


-EEG -> multiple copies of the 1 channel bipolar (TrueSense Kit) sensor, multiple copies of MindWave Mobile (1 channel) and Muse (4 channels), Emotiv Epoc+ (14 channels), KT88 (16 channels, photic stimulation), AMEA slow potentials mapper (2 channels). We have also made an EEG sensor for an audio jack of any smartphone at IMFcamp hackathon - see above.


-tDCS (transcranial direct current stimulation) -> DIY, via Starstim, via foc.us etc.


-tACS/tPCS (transcranial alternate current stimulation) -> DIY, foc.us, thync, Rhythm-2 2 channel tPCS stimulation device, DrTES (transcranial analgesia device)

Miscellanea:

Michael Persinger's "God Helmet" effectiveness has been reproduced by an independent group: http://www.scribd.com/doc/267811996/God-Helmet-Replication-Study

Possible step towards CEMI: http://www.sciencedaily.com/releases/2016/01/160114121806.htm

First they ban enhancing substances, and then go after the devices! Join the campaign if you are not indifferent.


Of course, you are more than welcome to suggest other relevant ideas to test and projects to try. The possibilities are, indeed, "Limitless" (pun intended).


P.S.: folks from Mind Hacking and Biohacking groups are, of course, welcome to join in, but we surely need electronics and coding enthusiasts interested in such matters!
