Cruelfox, a forum expert, has updated his article to share with you an experimental idea of a CNC experimental power supply. The power supply uses two domestic chips, with a 3,000-word detailed explanation. He briefly talked about the first experimental power supply he made, whose shell was an aluminum medicine box and whose knob was a toothpaste cap. He mainly talked about the ideas and principles of the current mini PCB pocket version.
The Raspberry Pi microcontroller 24-channel 100Msps logic analyzer has been upgraded to support 120 channels.
Daisy chaining of five devices is supported, allowing capture of 120 channels. Includes performance improvements and visibility improvements to the rendering engine, more samples in the screen, automatic selection of capture modes, editing capabilities, and more. The playability is getting higher and higher.
It's all open source, and their documentation is very detailed, which is a rare learning material.
This design is a wing add-on that attaches to the OrangeCrab and adds a Sharp Memory LCD. 400x240 on/off pixels. The board is the size of the monitor.
This project includes all the software and hardware design required to develop the T12 soldering station. The PID parameters are mature and the function completion is very high.
Supports voltage, current, effective power, apparent power, power factor, frequency, and harmonic component display.
SYZYGY is an FPGA extension standard for medium to high speed interfaces. This breakout connects the Channel 0 TX/RX SerDes from the SYZYGY-TXR connector to the edge of the card to act as a PCIe x1 add-in card.
Alex Newton released an IoT electrocardiogram monitoring (ECG) tutorial based on ESP32, demonstrating that remote cardiac monitoring can be carried out no matter how far the distance is between the doctor and the patient.
"Bluetooth controlled car based on stm32f4" is a motor drive module, power management module, stm32f4 main control module, Bluetooth serial communication module, and android control module based on the STM32F4 DISCOVERY development board produced by STMicroelectronics and ARM. The motor drive module uses two L298N chips to drive 4 motors. The enable terminal is connected to 4 PWM wave signals from the main control board, and the 8 input terminals are connected to the 8 output ports of the main control board; the power management module uses LM2940 -5.0 chip converts 12V to 5V, 12V is used for power supply of motor modules, and 5V is used for power supply of Bluetooth modules, sensors, etc.; the main control module uses the MDK editing program and then downloads it to the main control board to realize the integration of hardware and software Interaction; the Bluetooth serial port communication module uses the FBT06_LPDB pin-in Bluetooth module to communicate with the main control board through the serial port and at the same time communicate with the android phone; the android control module is a set of functions such as turning on Bluetooth, searching for Bluetooth, and controlling the car. Users can control the movement of the car through the android control terminal to achieve some functions and services that users need.
Introducing a simple and highly scalable application solution - a data acquisition instrument developed based on the MM32W series.
The Jlink OB made by F072 has a maximum speed of 3000kHz, and the Jlink V9 has a maximum speed of 12000kHz.
Supports various Cortex-M cores, can be used wirelessly in the local area network, and can be used remotely in the external network.
The led-panel originated from the author's desire to use a donated roll of white LEDs to break out 48 LEDs on a compact board. Its output power should reach about 4W. It has no controller and is purely for testing a set of LEDs to see if they would be suitable for some form of lighting attached to a gooseneck.
A hardware control circuit with TMS320F28335 as the core was designed, and experiments were conducted on the AC speed regulation SVPWM algorithm.
Main control chip: Hangshun HK32F030C8T6 Driver chip: two Toshiba TB67H450 (maximum current 3.5A) Encoder chip: Magone ultra-high-speed zero-delay AMR encoder MT6816 High-speed optocoupler: Toshiba dual-channel TLP2168 Working voltage: 12-30V (24V recommended) Operating current: Rated 2A (42 steps) 2.5A (57 steps) Maximum 3.5A Control accuracy: less than 0.08 degrees Electronic gear: 4, 8, 16, 32 (can be set arbitrarily)
This is a mature development board combined with a magnetic rotary encoder, which uses a Raspberry Pi RP2040 microcontroller with a base resolution of 36, expandable to 36,000 steps per revolution.
