A low-cost, non-contact DIY infrared thermometer based on ESP8266 can help people measure their temperature safely and prevent the spread of the new coronavirus.
These demos all use Adafruit's PicoDVI branch, which makes the video framebuffer look like a regular Adafruit_GFX object, which makes drawing very easy.
Mobile power supply (adjustment OK program + schematic PCB diagram).
The infrared controlled temperature alarm produced for this competition took half a month to make. It is a simple device made of AT89S52 with LCD 12864 as the display platform, including infrared remote control, temperature measurement, time display, alarm reminder and picture browsing. Infrared controlled temperature sensor.
Based on the STM8S handheld non-contact infrared thermometer gun MLX90614 forehead temperature gun design, including schematic diagram, PCB, source program, etc.
Tetris design based on STM32, including source program, schematic diagram, and PCB files
Supports continuous or intermittent monitoring of important biometric signals such as ECG, heart rate, HRV, PPG, SpO₂, blood pressure trend and respiration. It integrates daily use and advanced research applications.
The lithium battery charger project with USB type-C power transmission based on STM32G0 uses USB type-C with power transmission to charge the lithium polymer battery. Supports charging and balancing of 2s-4s packs, supports charging up to 100W.
Snake game design based on STM32, including program and PCB files
A project that uses a web page to remotely control the Raspberry Pi to send out infrared signals to control home appliances such as air conditioners. To put it simply, you can use your mobile phone to control it through the web page on the way home, turn on the air conditioner in advance, and set it to the required temperature. At the same time, the indoor temperature and humidity can be monitored in real time on the web page. The entire project is written based on Python's flask framework.
With voice recognition function, you can use voice to search for weather, as well as radio, temperature and humidity, calendar and other functions.
Electronic clock module schematic diagram + PCB diagram (2012 version), if you are interested, you can download it and take a look.
This Bilibili small TV uses esp32 as the main control, lvgl GUI interface design, and is developed based on idf4.0 to support smartconfig or WeChat airkiss distribution. Its functions include: network connection display, network acquisition time, weather display, temperature and humidity collection, Fan count display, mqtt temperature and humidity upload, etc. All software and hardware are open source.
Based on ESP32 and ATtiny861 to build a Nintendo NES game emulator handheld console with complete materials for making the project
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.
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.
Design of dual-tone doorbell circuit based on 555 timer
The project uses RSL10 to build a sugar glider health monitoring system. With good exercise and diet, my little jelly (sugar glider) can grow up healthily.
