Anti-mosquito laser defense system

Chinese engineers have developed a "high-tech" mosquito repellent that will stop you from being bothered by mosquitoes in the summer

He modified the radar on an electric car so that it could detect the flight path of mosquitoes, and added a powerful laser pointer as a weapon. As long as a mosquito enters the radar's monitoring range, the laser pointer will activate and shoot it down. In addition, he also developed a special "Death Note" to collect the bodies of all downed mosquitoes

Arduino quadruped walking robot

This project is about how to use 3D printing technology and Arduino to make a four-legged walking robot. By combining CAD model design and electronic knowledge, a cute four-legged robot is created that can not only walk, but also perform simple obstacle avoidance and interaction.

This project is not only a fun challenge for Arduino and 3D printing enthusiasts, but also an excellent learning material for those new to electronics work. The STL data for all required 3D printed parts is already available on Thingiverse and you can download and print it. In addition, the project also contains two Arduino sample programs, allowing you to easily control the robot's movements

Homemade 3D printed six-legged robot

This project was designed by a maker named Sir_Kuhnhero. It is a self-made 3D printed six-legged robot with an overall cost of approximately 120 euros. The robot is unique in that it has 271 independent RGB LED lights, a sophisticated cable management system, is also compatible with the Open Robot Platform (ORP) module, and can be remotely controlled via Bluetooth and a mobile app. Although this project is not easy, it will be very fulfilling after completion

3D Printing Spiral Propulsion Robot

This is a 3D printed spiral propulsion robot designed by gokux. It can move on land or water through a rotating spiral cylinder. The robot's design is simple and suitable for anyone with a 3D printer to build. The robot does not require complex parts such as ball bearings and is very lightweight. Based on the ESP32 S3, it can be controlled with a smartphone via WiFi and is able to obtain low-latency video signals from the robot.

Super long standby smart watch - can be recharged every ten years

The design concept of this smart watch is revolutionary - one charge, a service life of up to ten years! Its appearance allows us to no longer worry about insufficient battery power in the watch.

The secondary goal of this project is to further learn and improve knowledge of embedded full-stack circuit and device design for wearables, ultra-low power, maintenance-free battery-operated, wireless, application-driven, and off-grid devices. The watch was developed from scratch to provide developers with an excellent hands-on opportunity to learn about low-power, self-powered devices. Although this is not a commercial project, it is an attempt to advance low-power technology to a whole new level.

Features of the watch include ultra-long service life, no maintenance, waterproof, solar/RF power supply, multi-time zone display, automatic time adjustment/setting, etc. It can also integrate compass, altitude, GPS, atomic clock synchronization, accelerometer, NFC, BLE and other functions. The screen of the watch is made of sapphire crystal to ensure durability

The software and hardware used in the project include custom low-power PCB (printed circuit board), NRF52 Bluetooth chip, LCD display, IMU (accelerometer/gyroscope) and magnetometer, etc. The daily progress of the project can be viewed in Hackaday's project log.
