Introduction: The welding is ugly, but it works normally. As an IoT smart socket experiment board, its main functions are basically realized. Friends are welcome to communicate with each other.
Introduction: This project is a visual multi-functional electronic load that can select constant current, constant voltage, and constant resistance modes, and the maximum load power can reach 45W.
Introduction: Based on the GitHub open source project RX5808 open source dual receiving source project address: https://github.com/sheaivey/rx5808-pro-diversity
Introduction: Card game console based on esp32, using 2.4-inch screen, firmware address: https://github.com/Curtainzero/esp32retrogame
Introduction: Connect the sensor analog signal and program to realize output control. It can also perform duty cycle speed adjustment, light dimming, temperature adjustment and other controls. The output control uses IRF540 and optocoupler signal isolation.
Introduction: Based on ESP8266, pseudo Nixie tube, no copper pillar version 10cm * 2cm size patch lamp is 0807 ws2812
Introduction: When making a keyboard, I found that the power consumption of ws2812 is very high. Some friends later said that using the 3733 solution can save energy, so I made this solution verification board, using 2 pieces of IS31FL3733 for cascade control.
Introduction: The game console platform built using Arduino is similar to the gameplay of FC red and white console. Currently, the test can run 4 games stably. The device outputs AV TV signals for display and provides audio output. There are 5 buttons on the board, and the virtual serial port and other spare IO can be used to expand control devices such as handles.

Introduction: DIY Personal Split SMT Flat Heating Table
Introduction: A battery management module based on Arduino for four-string battery packs with functions such as battery capacity estimation, over/under-voltage protection, over-current protection, and upper-level serial communication.
Introduction: OnStep-MaxESP is a telescope goto driver integrated board based on the ESP32 development board
Introduction: Use the DFPlayer module and the esp8266-12f module to jointly realize the smart speaker function. It has various power supply methods and supports external USB.
Introduction: A real-time update clock for the Internet of Things designed based on ESP-C3F-12F microcontroller.
