This content introduces the schematic design and related procedures of the quadcopter in detail, which is great.
Tigard is an open source, multi-protocol, multi-voltage hardware hacking tool based on FT2232H. By combining commonly used pins, labeled harnesses, onboard level translation, and logic analyzer connections, it is specifically designed to connect to and communicate with low-speed interfaces on reverse-engineered hardware targets.
Traffic light control system principle design drawing
With timing settings, night mode, manual control and other functions
The project is a cube shaped 10x10x10 LED matrix controlled by a serial interface.

jlink-v9.5 schematic diagram, you can directly learn the JLINK principle
PlainDAQ is a simple, useful tool that adds basic precision analog functionality to your Raspberry Pi Pico board. It features a precision, low noise, low drift 12-bit 500k sps/s ADC. To match the ADC and maintain its noise and accuracy, all analog inputs are buffered and the ADC is driven by a high speed/low noise fully differential amplifier. It also has a 10-bit DAC that helps create analog outputs and waveforms.
cuplTag is a battery-operated NFC tag that records ambient temperature and humidity. Tap it with your NFC-enabled phone and you'll see the timestamped reading appear in the web app. No configuration required, no application installation required, just one step!
The Micro WS2812 2020 RGB LED Matrix is a micro 25x25 mm 8x8 WS2812-2020 matrix. It's only about 1 square inch, or about a quarter the size of the United States. This micromatrix is daisy chainable, meaning you can stack boards side by side while using only one data pin. Best of all, this matrix is compatible with all other WS2812 related matrix codes and is open source. Despite its small stature, this matrix has everything you need, with pad connections for VCC, ground, data in, and data out. It works with 3.3 V or 5 V and is capable of outputting 16 mA per LED.
This source code is based on the C language code of stm32f103 and is the source code of a complete robotic arm control project.
This design developed a fingerprint recognition electronic password lock system based on a single-chip microcomputer. The system uses STC89C52 microcontroller as the core of the module. It controls the ZFM-60 fingerprint module through serial communication to register fingerprints and store fingerprint data. It displays the comparison process and results through the HS12864-15C LCD, supplemented by DC relays and light-emitting diodes to simulate unlocking. Actions. This system has small size, high cost performance, fast transmission speed, and is suitable for families and organizations.
The self-balancing car uses the power of the car model to keep the car relatively balanced, which is a dynamic balancing process. The power to maintain the balance of the car model comes from the movement of the wheels, driven by two DC motors. The hardware of the car is divided into three parts, namely the main control part, the car attitude acquisition part and the motor drive part.
PCB: EB712ST-LX03-120327 The program has not been verified and looks poorly written. The PCB is worth reference.
