The biggest feature of this open source oscilloscope is its strong waveform rendering (afterglow/fluorescence) effect. At the beginning, the author used Raspberry Pi Module 3, which can render 22,000 frames per second. In the later stage, NVIDIA Jetson is used, which can render 130,000 frames. frame. ZYNQ's FPGA is responsible for triggering and data acquisition, and A9 is responsible for transmitting data to the Raspberry Pi. Then the Raspberry Pi does the display processing. The ADC uses 1Gsps HMCAD1511.
Use a reading pen with a Renesas Electronics RL78/G14 microcontroller, ISL80505 single-output low-dropout linear regulator (LDO), and ISL6294 high-input voltage charger to read the code printed on the paper and play the corresponding Audio.
WiCAN is a powerful CAN adapter based on ESP32-C3 that can be used for car hacking and general CAN bus development. It is available in two form factors: OBD-II and standard USB-CAN. The original firmware can interact directly with RealDash using Wi-Fi or BLE, which allows you to create custom dashboards with beautiful graphics. It is available for Android, iOS, and Windows 10. WiCAN connects to your existing Wi-Fi network and any device on that network, and it allows you to configure Wi-Fi and CAN settings through a built-in web interface. Both versions have a power saving mode that detects when the voltage drops below 13 V or other preset values. When this power saving mode is enabled, WiCAN is able to enter sleep mode, reducing the current consumption to less than 1 mA.

After the user manually solders a PCB board, this board becomes the reflow controller, and then this board can be used to control other boards for reflow soldering, because this board has been specially designed to open a heating layer.
This reference design provides a power-supply circuit with an input voltage of 3.3V, an output voltage of 1.8V, and an output current of 1A using the MAX8869 low-dropout linear regulator. The circuit was developed to power a MGTVCCAUX rail on a Xilinx® Kintex® Ultrascale™ FPGA. Included in this reference design are a schematic and a bill of materials.
Plankton help remediate 30-50% of the world's carbon dioxide and provide the foundation for the global food chain, making up the world's largest daily movement of biomass as it travels across the ocean. The shapes, colors, and movements of these billions of creatures are as vast as the oceans that sustain them. Understanding plankton is crucial to understanding the world around us and our impact on it.
One obstacle to this type of research is the sheer size of the area to be explored, as well as limited resources for research fleets and specialized equipment. By developing a method to scale up high-quality visual exploration and documentation, we can greatly increase our understanding of the complex web of life around us, and how we in turn influence it.
The Wi-Fi smart power strip using RL78/G13 microcontroller and ISL85003 regulator can remotely control the opening and closing of each power socket through Wi-Fi.
CluonCV provides an implementation of state-of-the-art (SOTA) deep learning models in computer vision. It is designed for engineers, researchers and students to quickly prototype products and research ideas based on these models.
This reference design provides a power-supply circuit with an input voltage of 10.8V to 13.2V, an output voltage of 1.80V, and an output current of 2A using the MAX15303 InTune™ Point-of-Load (PoL) Controller. The circuit was developed to power a VCC1V8 rail on a Xilinx® Kintex® Ultrascale™ FPGA. Included in this reference design are a schematic, applications information, and a bill of materials.
The MPC8272ADS board is designed to aid hardware and software developers of the PowerQUICC II family by providing an evaluation platform for MPC8272/48 derivatives in the 516-pin PBGA (ZQ/VR) package.
Detecting low-g acceleration using the ADuC7024 precision analog microcontroller and the ADXL345 digital accelerometer
Based on NXPThe Ethernet Video Development Kit for the MPC5604E MCU is suitable for next-generation automotive and general market camera applications.
Evaluation board for the ADC120 8-channel, 50ksps to 1Msps, 12-bit analog to digital converter
Implement precision electronic scale design using the 24-bit Σ-Δ ADC AD7190 with built-in PGA
This reference design circuit introduces a high-precision bidirectional current power supply solution used in battery test systems (BTS). The maximum current capacity is 6A, and the full-scale accuracy is less than 0.05%. Controlled by logic pins, this circuit can be used to charge or discharge the battery. During the charging process, the battery voltage can also be controlled through analog signals. Design of this circuit is simple and easy due to the fully integrated buck and boost converters. The performance of the solution can be verified via a built-in evaluation board.
This video records the entire process of the author and his team building a low-cost ornithopter.
