The STM32 Nucleo-64 board provides an affordable and flexible way for users to try out new concepts and build prototypes by choosing from the various combinations of performance and power consumption features, provided by the STM32 microcontroller.
This little robot is called ONE, which is actually a work UP made when he was in school five years ago. After finishing it that year, I never had time to sort out the materials. During this period, many classmates came to ask me questions related to this project. This time, I simply uploaded the materials to Github and made them open source. Open source information includes the source code of the STM32 main control and the 3D model files of the mechanical structure. The circuit source files can no longer be found due to their age. Students with basic knowledge can study it by themselves~
STM32 Nucleo-64 development board using STM32G474RE MCU, supporting Arduino and ST morpho connections
The product design is open source and very cool and beautiful.
STMBL is an open source servo driver designed for CNC machine tools and robot modifications. It supports industrial AC and DC servos up to 320V and 2kW.
Amethyst is a classic home computer developed by Matt Sarnoff. It has an integrated keyboard, can generate sounds and images, uses the Forth programming language, has image and voice commands, a debugger and screen editing functions.
The Raspberry Pi microcontroller itself does not have an Ethernet MAC, but it can be easily implemented through the programmable IO of the Raspberry Pi. The programmable PIO of the Raspberry Pi microcontroller that costs 5 yuan a piece is indeed a miracle, with IO below 250MHz. Control everything.
The hardware design adopts upper and lower layer design. The upper layer is the control circuit and the lower layer is the dual receiving circuit. The interface design is based on LVGL.
The EEZ Bench Box 3 (BB3) represents a new class of modular test and measurement (T&M) equipment. It provides a complete open source hardware and software framework that bridges the gap between DIY hobbyist tools and professional desktop equipment and combines their best features. Inspired by the EEZ H24005 power supply, BB3 has attracted many enthusiasts with its extensive feature set, rich user interface, DIY friendliness and completely open source design. BB3 will initially feature modules that provide the same functionality as the H24005, but these modules will plug into a single device, providing improved modularity, greater capacity, more processing power, an easier-to-use interface and enhanced flexibility, all These are available in compact form factors.
This project is a completely open source smart watch based on the ESP32 WROOM module, with a very high degree of completion. In the project design, serial communication and charging are completely through the onboard micro USB interface, without any external interface board processing.
The system is an intelligent tracking device based on TMS320F2812, which has the function of intelligently locking targets and automatically tracking locked targets. CPLD is used to obtain image information collected by the camera, and TMS320F2812 is used to process the image information. Median filtering, corrosion and other algorithms are used to extract target information, and then the target coordinates are calculated. The car movement is controlled through the internal PWM module of the DSP, and the target coordinates are wirelessly sent to the handheld device. Remote control device to achieve real-time tracking of targets.
