Killer Power Electronic Circuit

=Problem Definition= We first found a circuit that uses two identical photoresistors and two identical relays to detect the direction of movement of objects. After we are familiar with and understand its specific working principle, we start to determine the power supply voltage and components in the circuit through calculations Resistance range and selection of component specifications. 1.Design sneaky ways to serve as killer circuit to destroy the main circuit. 2.Simulate the main circuit and the combined circuit. 3.By calculating the power supply voltage of the circuit and the resistance range of the components, we can select the components of the required specifications. 4.Purchase components and build the final product. 5.Circuit debugging and experiment

=Objective= The goal of this project is to install a hardware Trojan horse on the designed circuit produce the finished product.

=Background= The project requires the addition of a Trojan horse to a familiar circuit. Make a circuit to realize self destruction is the premise of the circuit has a very thorough understanding of the permanent self-destruct or transient circuit self-destruct will be applied in many aspects of our life, whether it is necessary measures to protect the safety of property information electronic science and technology company, or entertainment aspects involved, the design of the circuit self-destruct has broad application prospects.

=Choose A Suitable Circuit=

Principle
when the object moves from the photosensitive resistor RG2 to the direction of RG1, the RG2 is firstly blocked by the object, which causes the RG2 resistance value to increase and the bridge balance is destroyed. The bridge output UAV is less than 0.Compound pipe Q1 on, Q2 up.Relay K1 coil has current flow, the relay is often open contact suction.By the same principle, according to the working order of the relays, we can judge the direction of the object's movement.
