Implementation of a Micro 3D Endoscope Based on FPGA and OV6946

1. IntroductionMicro endoscopes typically operate in confined environments with relatively small operating spaces and are widely used in fields such as medicine, aerospace, semiconductors, and security. In some applications, such as minimally invasive surgery and neurosurgery, more precise stereoscopic positioning is often required. However, conventional endoscopes typically use a single lens, which only produces two-dimensional images and cannot provide accurate three-dimensional information. This solution....

What causes overshoot when using a MOSFET to control the shutdown of a resistor voltage divider?

In electronic circuit design, MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) are widely used in power control and signal switching circuits due to their advantages such as low on-resistance and high switching speed. When MOSFETs are used to control the shutdown of resistor voltage divider circuits, voltage overshoot phenomena may occasionally occur. This not only risks damaging other components in the circuit but also affects the stability and reliability of the entire circuit system. Understa....

How to Suppress SiC MOSFET Spikes Using a Buffering Circuit

In recent years, the application scope of SiC MOSFETs as switching elements in various power supply applications and power lines has been expanding rapidly. One of the main reasons for this is that, compared to previous power semiconductors, SiC MOSFETs enable high-speed switching operations. However, due to the rapid changes in voltage and current during switching, the effects of the device's own package inductance and the parasitic inductance of the surrounding circuitry become significant, leading to lar....

Application of DC brushed motors in automobiles

Introduction to Brush-Type DC Motors Brush-type DC motors, commonly referred to as brush motors, are a type of DC motor widely used in household appliances. Their key components include fixed main poles and brushes on the stator, as well as armature windings and commutators on the rotor. Electric power from the DC power source enters the armature windings through the brushes and commutator, generating armature current. The magnetic field produced by the armature current interacts with the main magnetic fiel....

How can the MCU continue to complete the corresponding operation when the power is slow to power on?

In electronic systems, the microcontroller (MCU) is the core control unit, and its stable operation depends on a reliable power supply. However, in actual applications, the power supply may be slow to power on, which poses a challenge to the normal startup and subsequent operation of the MCU. To ensure the stability and reliability of the system, the MCU needs to adopt a series of strategies to deal with the problem of slow power on and continue to complete the corresponding operation. Countermeasures at ....

Reversed power supply polarity causing board damage? Here are some solutions.

Many hardware engineer projects are completed on perforated boards, but there is a risk of accidentally reversing the power supply polarity, which can cause electronic components to burn out and even render the entire board unusable, requiring the board to be rewired. Are there any good solutions to this problem?Firstly, carelessness is inevitable. Although distinguishing between the positive and negative terminals is as simple as identifying the red and black wires, we might not make a mistake when connect....
