83- P-Channel Light Sensor
$27.95 – $77.95
This circuit uses an RC Timer to arm and a light sensor to fire. The bomb is placed in darkness, and the bomb is stable. When the ambient light increases, the resistance on the voltage divider of LDR1 and R1 starts to decrease until it arrives at a level where it allows current to flow through Q1 to the detonator.
