Using the Edge Impulse platform, an embedded machine learning (ML) model is deployed on the ESP32-DevKitC-based sensor for temperature anomaly detection.
Quark based on ESP32 is an open source electronic tool that integrates electronic measurement probes and debugging tools. It has a wireless connection function and can be connected to APP.
PocketSprite is more than just a small gaming device that clips to your keychain, it's an open source, powerful and mature hardware development platform.
Recently, Sebastian Staacks, a physicist and development engineer from Germany, created a unique electronic guestbook for his brother's wedding. The guestbook is developed based on the ESP32 Wi-Fi module. All wedding guests can log in to a simple web interface through their mobile phones, enter text messages and upload pictures. Affected by the COVID-19 epidemic, some friends cannot be present, but they can express their greetings and blessings to the couple remotely through this guestbook.
SwarmDrive based on ESP32 has rich teaching documents, professionals and students can use it to easily learn various commutation algorithms and related knowledge of BLDC motors.
tCam-Mini is a small wireless thermal camera designed and developed by Dan Julio based on ESP32, which allows users to easily obtain and use radiation data through the Flir Lepton 3.5 sensor. It can obtain the temperature of each pixel and perform various types of thermal imaging analysis; it can also convert the data into color images to display the temperature and shape of the human body through thermal imaging.
The color screen projection assistant uses the tcp protocol to send the computer screen to esp32 for processing and display in real time, with a theoretical frame rate of more than 10 frames
Use the PIO plug-in of VSCode to directly open the project folder under the Code directory for compilation~
Modified from the ESP32 Arduino routine "CameraWebServer" 1. Treat ESP32 as a web server. You can see the camera monitoring screen and control it through browser access. 2. Mainly change the web page from English to Chinese and delete some functions. 3. Added control functions for servos, motors, relays, and LEDs. 4. Through this program, you can easily create a wireless reconnaissance robot with ESP32.
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~
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~
The quality of mobile phone screens is very high and the price is low. It is almost impossible to find mini displays made of mobile phone screens on the market, so this project is to solve this demand.
Genesis One uses STM32F103RCT6 as the main control, integrating lithium battery charge and discharge management, voltage stabilization, Bluetooth serial port HID, USB-HID, LED light array driver, and button detection circuit. It can realize Bluetooth connection mode (supports IOS, Android and other platforms) and USB connection mode. The response time of Bluetooth connection is about 15ms, and the response time of the master control in USB connection mode is about 0.3Ms.
With electronic ink screen, can simulate various IC cards
The author introduces the classic corexy structure writing machine.
IndyMill is an open source DIY CNC machine
The Jlink OB made by F072 has a maximum speed of 3000kHz, and the Jlink V9 has a maximum speed of 12000kHz.
Use an idle Android phone to place it on a drone or unmanned vehicle/boat to realize wifi, 4G, 5G remote control of the drone, image transmission/data transmission/remote control integration. Supports APM and Pixhawk flight control (as long as it is compatible with Mavlink protocol), supports RTK differential GPS high-precision positioning (optional function, requires ublox NEO-M8P GPS module and Qianxun FindCM service account).
APM (ArduPilotMega) is a flight control product launched by the DIY Drones community in 2007. It is the most mature open source hardware project today.
