electro-mechanical turk

introducing the electro-mechanical turk: We connect a photodiode and a solenoid to an Arduino, place the diode at a screen and the solenoid over a keyboard, and can now measure precisely how long stimuli are presented on the screen by ScriptingRT, DMDX, e-prime, or other programs, and how long it takes the software to register a keyboard button press. everything open source of course.
