Recommended Interconnection Methods for Phyphox and External Sensors ——Also answering a question from a certain student at a university Since I started using microcontrollers to expand the external sensor technology of Phyphox about one or two years ago, I have experienced the process of connecting Phyphox with ESP32, Arduino UNO + Bluetooth BLE, Arduino Nano … Read more
Today, I present to you a work from creator X: the blind assistance environmental perception device. This device mainly utilizes the Grove Vision AI V2 camera module to identify objects in the environment and uses XIAO ESP32S3 and Raspberry Pi for voice output, combining object detection and text-to-speech technology to provide environmental information to visually … Read more
Implementing edge computing in embedded systems is becoming increasingly popular, with several platforms beginning to support it, utilizing TinyML – compact machine learning. In addition to the eighth edition of Arduino Nano 33 BLE launched by our company, ESP32, QuickLogic’s QuickFeather, and PICO are also building an ecosystem around TinyML. We will gradually launch activities … Read more
Previously, I wrote a few examples of how to use C# to write STM32 programs. Similarly, we can also use C# under ESP32, relying on the ever-growing .Net nanoFramework. Currently, it supports more and more development boards and chip types, and the related libraries are also increasing. The supported devices can fully support conventional application … Read more
Hello, I am Little Fish who loves fish-flavored dishes in ROS. In the last section, we completed the measurement of distance at a specified angle. This section will synthesize it into a ROS LaserScan message and publish it to the upper computer through Micro-ROS, ultimately achieving visualization in RViz2. Hardware Development Platform For convenience in … Read more

| Indoor Test Flight | After the Storm, the Rainbow Appears To enable the BETAFPV 915 Nano to support PPM output from the FUTABA T14SG, an ESP32 development board was used. After coding twice with Mu Ge (Bilibili ID: Er Mu Shan Ren), it was finally ready for test flight. Although ELRS is high refresh, … Read more
【Research Background】 Replacing graphite anodes with lithium metal anodes (theoretical specific capacity of 3860 mA h g–1) is considered one of the most attractive ways to improve battery energy density. The electrolyte plays an important role in insulating electrons but conducting ions between the electrodes, thus promoting battery performance. With the rapid development of electrochemical … Read more
