New tDCS Regulator Designs
I released a simple pcb design last week for a stimulator based on the goflow schematic.
I've been working on a few more ideas and have posted two new schematics and one new board design. All the schematics, board designs and (eventually) code are hosted on github [v1][v2][v3]. The schematics and pcb layout are done with free, cross-platform gEDA (and friends) and the licensing is nonrestrictive (CC-BY).
I am still waiting for the prototypes to return from oshpark, I'll have a better idea of the electrical characteristics when they arrive. I'll also probably catch some blindingly obvious (in retrospect) errors.
There was a lot of great feedback in some of the other tDCS discussions, including info from a few EEs. I am new to EDA and electronics and would appreciate any input (feedback, commentary or patches against the repo).
