Just for Fun: tDCS in a Bottle | SpeakWisdom

I decided to borrow Keith’s design one more time and build a simple tDCS device into an old pill bottle, just to show how easy it is to build a current regulated tDCS device – and to show how small they can be. My latest creation could easily be carried in a pocket or tucked in a hat. I call it “tDCS in a Bottle” and yes – I decided to copyright the name – hey why not?

My simple circuit consists of a type 25A 12v volt battery, a 2.2 k Ohm resistor, a current regulating diode (CRD), a pill bottle, and some lead wires. You could build one yourself in 15 minutes or less!
