Found an AmerTac at Wally world, Motion Activated Utility Lite. Only problem I've found with it so far is that it activates for 30 sec at a time, and the output voltage is .59 volts. Trying to determine which cap and resistor control the activation time right now, later I've got to figure out the voltage regulation. Uses 6 vdc.

I've been calculating values and trying to match caps w/ resistors to try to find which control the trigger length. Anyone got any other suggestions? Found it! Now to try to increase the output voltage.
