Arduino® Nicla Vision is a ready-to-use standalone camera for analyzing and processing images at the edge. It's suitable for asset tracking, object recognition and predictive maintenance thanks to its 2MP color camera, smart 6-axis motion sensor, integrated microphone and distance sensor. Quickly implement sensor nodes that send collected data to the Arduino® Cloud (or third-party vendor service) via integrated WiFi/BLE connectivity.
The project is a small desktop-level robot tool that can be used to help you control your computer, etc. Its functions can be defined by you. The inspiration for the appearance design is EVE in WALL-E~ The robot has a USB communication display screen function, has 6 degrees of freedom (one roll and pitch for the hand, one for the neck, and one for the waist), and uses its own modified special servo to support the joints Angle return.
Zhihui Jun designed and produced a portable pocket monitor (& power bank) to solve personal pain points. There is no room for improvement in terms of appearance~
Arduino development, weather, clock, reading, network distribution and other functions
This article briefly introduces the application example of sensorless sine wave drive technology based on MM32SPIN25 in "handheld vacuum cleaner".
SYZYGY is an FPGA extension standard for medium to high speed interfaces. This design is a breakout board for connecting dual Atto320 LWIR sensors. Designed to mate with existing sensor breakout boards that provide FFC connectivity.
Using TPA3110 digital power amplifier chip, the power can reach 15W, and there are two power interfaces. The Bluetooth part uses bk8000L finished module, which has good performance and affordable price. Supports button playback and pause, track switching, volume adjustment, and also supports external audio line input and microphone input. After testing the finished product, the sound quality is good, the Bluetooth connection is relatively stable, the button functions are normal, the external audio line input is normal, and the microphone calls are normal. A complete AD project file is provided, which can be modified as needed, and the BOM needs to be exported by yourself.

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.
SYZYGY is an FPGA extension standard for medium to high speed interfaces. This design breaks out all 32 I/O pins into taps with 0.1" headers. A small prototyping area is also provided.
Open the laptop's built-in camera through matlab and detect faces.
Pocket calculator style general purpose programmable device (computer) ideal for learning programming and improving building/soldering skills.
AT89C52 microcontroller is used as the core control component to design an electronic keyboard. The microcontroller is used as the main control core, and it forms the core main control module together with the keyboard speaker and other modules. The main control module is equipped with 8 buttons and a reset button.
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.
The product design is open source and very cool and beautiful.
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.
