Schematic PCB

AC current measurement system based on STM32 (program, circuit information)

The overall structure of this design is roughly composed of a main control module, a current signal sampling module, a power module and a serial port output module. In this article, the main control chip uses a microcontroller model STM32F103RC, which makes the structure as small as possible while ensuring the current sampling accuracy. It is as simple as possible, avoids complex and changeable circuit layout, is more convenient for PCB board production, and is relatively low-cost. Among them, in the design of the sampling conditioning circuit, a current transformer is used to sample the current signal.

Lite3DP 3D Printer: Arduino-based open source MSLA / LCD-SLA resin micro 3D printer kit (schematic, PCB, source code, etc.)

Lite3DP is a micro 3D printer that uses high print quality, virtually silent MSLA technology. It is the first of its kind to be completely Arduino-based, is open source, and comes in an easy-to-assemble kit format. It is a simple machine designed for experimentation to provide an in-depth and complete understanding of its operation. It can be placed on almost any table or in any workshop. MSLA resin 3D printing technology can achieve stunning levels of detail and surface finishes that are far superior to what can be achieved with filament 3D printers – primarily by using screen-cured resins such as LCDs on Lite3DP. Although 3D printers with MSLA technology are already available at similar prices to filament printers, they are closed-source projects that eschew one of the most valuable features of modern 3D printing - accessibility.
