A fairly simple, slightly unsafe and highly voltage limited arduino project that is somewhat clever is located [http://sourceforge.net/p/openbrainstim/wiki/Hardware/ here].
A fairly simple, slightly unsafe and highly voltage limited arduino project that is somewhat clever is located [http://sourceforge.net/p/openbrainstim/wiki/Hardware/ here].
The cadillac of designs here would probably look something like an arduino controlling a SPI variable resistor connected to an LM334 for current control, another LM334 with a fixed resistor to provide failure protection (a fuse is going to blow too slowly and fuses that small are expensive and difficult to source), a shunt ammeter connected back to the Arduino and a display/input to allow the user to set different times, current levels, sham stimulation and so on. Also we would want to put a boost transformer on the battery supply in order to boost the output voltage being used. Discussion of why we want to up the voltage here will happen in the section on electrodes.


(need to add a long discussion about electrodes here, since there is more complexity in the electrodes than the circuit itself)
