The goal of PSLab is to create an open source hardware device (with all resources fully open) that can be used by electronics enthusiasts to do experiments. And offers a range of sensors for engineering experiments, including oscilloscopes, waveform generators, frequency counters, programmable voltage, current sources and data loggers.
This DIY LiPo super charger can charge a single LiPo battery and protect it from overvoltage, overload and short circuit. In addition, it can boost the battery voltage to 5 V or 12 V. The boosted output voltage is protected by an "eFuse" IC with a maximum output current of 1.52 A at 5 V and 0.76 A at 12 V. The charger part of the circuit requires a +5V power supply, which can be connected via USB-C, or simply solder two wires to pads on the PCB. Additionally, other connections can be soldered to pads on the PCB or use individual pin headers.
STHV800 Ultrasonic Pulse Generator IC Evaluation Board
Low-cost, 8-channel, simultaneous sampling data acquisition system with 84 dB SNR and excellent channel-to-channel matching
Industrial digital output expansion board for STM32 Nucleo, based on ISO8200BQ
Few elevator maintenance managers need to manage and maintain a large number of elevators, making it difficult to detect elevator faults in time. Based on ST's SensorTile, the author implements the sensor's automatic detection of elevator arrivals and faults, which can serve as input for possible intelligent control systems, thereby enabling more efficient and convenient elevator use and management.
The SABER board for smart devices is based on the i.MX 6Quad processor and supports 4-core processing, low-power multimedia and graphics applications.
The Fremont (MAXREFDES6#) subsystem reference design meets the high-resolution needs of low-voltage output sensor applications. Boards for purchase, hardware and firmware design files, and FFTs and histograms from lab measurements provide complete system information for rapid prototyping and development.
5 kW low voltage high current inverter for automotive motor control applications
This project uses the LSM6DSOX+STEVAL-MKI109V3 mode for preliminary sensor learning and research, mainly from training the acceleration sensor to detect vibration and recording vibration waveforms, training the gyroscope sensor to detect the vibration direction and offset, and recording the waveform for analysis; combined with the acceleration sensor and the action data of the gyroscope sensor can determine the vibration intensity and direction of the wind turbine tower under various working conditions; in practical applications, the LSM6DSOX sensor is combined with the low-power chip STM32L010RBT6 chip, and the main control board on the local side leads to an alarm relay. The outlet is used for alarm output on the wind turbine tower side. It is connected to the wind turbine scada system through 485 serial port communication to upload the recorded data on the local side to provide real-time feedback on the working status of the wind turbine tower. It can be used to analyze the vibration reverse and wind turbine tower vibration. Swing direction recording can also record and analyze the natural frequency of the wind turbine tower under normal conditions and the natural frequency during faults. The multi-faceted data forms a wind turbine tower disaster warning system that can be sensed in advance;
