OpenStim

OpenStim is a set of open-source hardware and software designed to administer transcranial direct current stimulation for less than $50.

IMPORTANT NOTICE
Recently, an error was discovered in the documentation page describing the commands for setting the stimulation polairty. The documentation originally indicated that setting operating_power to a positive number would set the output from W6 as the anode. This is not correct for the most recent version of OpenStim and has been corrected. Note that the correct cofngiuration is:

If operating power is set to a positive number the output from the digital potentiometer (W6) should be the cathode

If operating_power is set to a negative number, W6 should be the anode
