Pulse Pal 

Pulse pal is an open-source device that generates precise sequences of voltage pulses to control stimuli in neurophysiology and behavioral research.

Pulse Pal was developed was developed by Josh Sanders at Cold Spring Harbor. It was developed in a research setting, primarily to control stimuli in neurophysiology and behavioral research. Pulse Pal offers a set of features that improve upon and complement commercial stimulators (i.e. Master8, PSG-2, Pulsemaster, MultiStim). As an open source device, Pulse Pal provides a unique combination of technical flexibility and affordability for precise stimulus control. The newest version, Pulse Pal 2, is powered by Arduino Due (an open source ARM Cortex M3 microcontroller platform), to simplify firmware accessibility. It features improved surface mount components - a 12-bit bipolar DAC provides greater voltage precision, and an integrated microSD card allows channel parameters to be saved and loaded for enhanced use as a stand-alone device.
