#2yikes, be careful!
Hey, I'm curious how you plan to limit current issues through the electrode contact quality. I know when putting on EEG electrodes you can test the impedance, would something like that be needed here?

#3I'm really glad he did that so I didn't have to. The effects sound pretty cool though.

This whole thing reminds me of Uncle Rico's time machine in Napoleon Dynamite.

#5Why would they put 6mA when you are suppose to send 2mA?
9v/6mA is 1500Ohms. If they added a 3k resistor in series with their setup, they would've up the total resistance to 4500Ohms, resulting in 9v/4500Ohms = 2mA of current.

#6With two components you can build a variable constant current source very quickly: http://users.telenet.be/davshomepage/current-source.htm

To clarify, we measured about 8000 Ohms of resistance through the head, using our electrodes. For some reason, our measurement was off. I'm assuming it's a problem with the electrodes. To fix this issue, we'd need constant monitoring and adjustable resistance. In no way was I planning on running 6mA through my brain.

I guess you're just braver than me but constant monitoring and adjustable resistance are the barest minimum features needed before I'd even consider running current through my brain.
