Timer and Photocell Armed NO Switch Fired
$80.00
This circuit utilizes a quad AND gate IC to allow for 3 separate events that can occur in any order to fire the detonator. The circuit uses an RCTIMER, and normally open switch (pressure plate) to feed into a second AND gate with an LDR. The RC TIMER must be above the threshold voltage, the pressure plate must be closed, and the LDR must be in daylight to fire. The circuit uses an N Channel MOSFET to fire a single detonator.
