OpenStim is a set of open-source hardware and software designed to administer transcranial direct current stimulation for less than $50.
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
- Hardware costs less than $50 and can be built in a few hours
- Supports tDCS, tACS, and tRNS
- Automatic double-blinding and support for data logging and sham trials
- Safety features--ramping, automatic shutdown on error detection, real-time current monitoring, self-diagnostics, sensor calibration
- Reconfigurable via imprint files
- Automatically detects potential issues in stimulus configuration
Great project, thank you for your hard work, No recent updates? Any initial trials rezults yet? Good luck
Is there a way of running this on a mac?
Figured it out. The files the program calls for are .imp file type. The default files targeted are .bmp files. As usual, operator error! - mitch
