Current limiting circuitry involving tDCS
Hello, im new here and I have a special problem,
I would like to build a transcranial direct current stimulating device
you can find a lot of information on the web about it.
In theory it needs a 9 volt battery attached to two saline water soaked electrode
what is attached to the test subjects head, and the current flowing through the subject(the two electrodes) must be between 1-2 milliampere,
and unfortunately I'm not good at electronics, so I am asking You the experts to help me out,
What are the methodes to dynamically limit the current, so if even the resistance waries the current stays the same. Is it possible? what is the simpliest method?
Thanks in advance
Also i want to spark your interest
