Plant Bot is an open source project based on ESP32 that allows a single PCB to perform the functions of detecting humidity, watering, providing lighting, and controlling and communicating with the user via WiFi/BLE.
The WiFi remote control is based on ESP32 Pico D4 MCU and 160x80 pixel mini TFT display. Additionally, there are onboard I2C temperature and humidity sensors and an accelerometer.
Somu is a small FIDO2 security key that you can use with your Google, Twitter, and GitHub accounts for two-factor authentication, or with your Microsoft account for passwordless login.
Battery-operated fluorescent lighting projects often appeared in hobby electronic magazines in the 1980s. I always thought that fluorescent lamps were devices that only used AC power at that time. Those articles about using batteries to light miniature fluorescent lamps attracted me. I made some fluorescent lights, but I couldn't get good practical use out of them from a lamp efficiency and longevity perspective. That's because I was just reading the article and knew nothing about the theory of discharge lamps or even electronics. I don't know what to change to get good results, and I'm losing interest in it. However I found a battery powered fluorescent light project online that was identical to the schematic I was working on. So I "revived" the project after 30 years with modern driver circuits and correct theory.
Grapevines use a lot of water and the soil dries out quickly, so they need to be watered twice a day. This project is about using an unmanned watering system to water flower pots.
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.
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.
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.
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.
Ported the 3D rotation + meteor shower background demo to H7, and the pure rendering is very smooth.
icebreaker++ is a very nice and convenient little board. But it has a small flaw, the ice40 FPGA it uses is very simple, and it's generally fun to see people doing exciting projects with 5k LUTs. Sometimes it's convenient to have some extra space available when experimenting.
Mega-Cube is a light cube that drives 4096 LEDs based on PL9823. The main control is Teensy4.0 based on NXP i.MXRT1060 FlexIO function and many 595 shift registers. It can control up to 32 channels, each channel 1000 LED.
The product design is open source and very cool and beautiful.
Label-free pose estimation from user-defined features via deep learning for all animals
CluonCV provides an implementation of state-of-the-art (SOTA) deep learning models in computer vision. It is designed for engineers, researchers and students to quickly prototype products and research ideas based on these models.
It is the first open source system to achieve 70+ mAP (75 mAP) on the COCO dataset and 80+ mAP (82.1 mAP) on the MPII dataset. To match poses corresponding to the same person in frames, an efficient online pose tracker called Pose Flow is also provided. It is the first open source online pose tracker to achieve 60+ mAP (66.5 mAP) and 50+ MOTA (58.3 MOTA) on the PoseTrack Challenge dataset. AlphaPose supports Linux and Windows.
Just like piranha and mimosa, when your hand comes close to the petals, you can quickly close the 6 petals. It can be opened automatically after leaving~
Let’s see how to easily hack a remote control using ESP8266.
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.
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
