A simple USB switch so I can swap a keyboard or mouse between two computers.
It is operated by 4 single mechanical switches, 1 for each channel. Simple designs can be implemented.
Embedded computer vision is a highly multidisciplinary field that requires expertise in optics, image sensors, hardware, firmware, and more. Therefore, the barriers to using technology in this field are quite high. The Vision FPGA SoM is a Lattice FPGA-based system-on-module that integrates an ultra-low power vision sensor, 3-axis accelerometer/gyroscope and I²S MEMS microphone in a small form factor (3 cm x 2 cm).
The circuit in this design can control the automatic operation of the water pump motor according to the water level in the water tank and the set time. It has been used for more than a year and has excellent anti-interference and stability. Now I will introduce it to peers and microcontroller enthusiasts. The specific circuit is divided into four parts: microcontroller circuit, power supply circuit, water tank circuit and motor control main circuit.

2-layer PCB 8.89 x 19.05 mm FR-4, 0.8 mm, 1, soldered with leads, white solder mask, black silkscreen
Using SPCE061A to develop a data acquisition system has great market prospects. First of all, its easy-to-learn and easy-to-use programming voice and development environment allow beginners to get started quickly; secondly, it has a modular structure and built-in 7-channel 10-bit AD, simplifying the user's circuit design; thirdly, it has voice Recognition and audio processing functions allow users to develop more intelligent products
The microcontroller uses MCS-51 series 89C51 (one piece), 74LS244 and 74LS373 (one piece each), inverting driver ULN2803A (one piece), and operational amplifier LM324 (one piece)
2 Layers PCB 42.2 x 68.8 mm FR-4, 1.6 mm, 1, HASL with lead, Green Solder Mask, White silkscreen;
The source code has not been verified, using C language, AVR microcontroller
Micro four-axis, complete design, anonymous small four-axis dry information sharing.
This project uses msp430g2231 as the core processing chip, which is composed of sensor acquisition module, wireless communication module, alarm module and host computer; two msp430 launchpads are used to simultaneously collect temperature and humidity through the dht11 temperature and humidity sensor, one as the host and the other as The slave machine uses a wireless communication module to communicate with the host machine, and the communication distance is more than 20 meters; the host machine directly communicates with the computer to transmit the temperature and humidity data to the computer, and at the same time, the upper limit of temperature and humidity can be set for The computer alarm can be used to differentiate between the host and the slave by playing specific songs or recording. In this way, you can first hear the changes in temperature and humidity. If you want to know the specific values of temperature and humidity, you can directly check it through the host computer. Specific temperature and humidity values enable real-time monitoring of the temperature and humidity of greenhouse vegetables, greatly improving the efficiency of large-scale planting.

Pixelblaze makes writing new LED patterns fast and fun using its real-time web-based editor and highly optimized expression engine. You can store a hundred patterns and write new ones by entering mathematical expressions or code that update in real time as you type. Pixelblaze is designed to make it easier to program LED patterns and intuitively understand how code and math affect those patterns.
In industrial control, it is often necessary to count and measure products to achieve automatic control of equipment. This article introduces a method of making a counter that can set the count value arbitrarily within the display range. Moreover, the current count value, set value, and magnification value will not be lost when power is turned off. It is compatible with a variety of input signals and has a magnification accuracy of up to 5 digits. It is easy to use, stable and reliable, and can be widely used in machine tools, rubber, printing, pharmaceuticals, and cables. , textile, complete sets of control equipment and other industries.
