With just a Raspberry Pi Pico, an analog switch and an op amp, you can build a powerful SDR receiver covering the LW, MW and SW bands. Capable of receiving signals from halfway around the world.
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.
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.
A simple power supply design based on USB-PD, USB-PD allows to provide voltage up to 20V (current up to 5A), the author shared his design details, you can have an in-depth understanding of the working principle of USB-PD.
ESP-Drone can be connected and controlled through Wi-Fi network using mobile APP or game controller. Currently, it supports multiple modes such as self-stabilizing flight, fixed-altitude flight, and fixed-point flight. This solution has a simple hardware structure, clear code structure, supports function expansion, and can be used in STEAM education and other fields.
Novena is a 1.2GHz, Freescale quad-core ARM architecture computer tightly coupled with Xilinx FPGA. It is designed for users who care about free software and open source, and/or want to modify and extend their hardware: all documentation for the PCB is open and freely downloadable, the entire operating system can be built from source, and it Comes with a variety of features that facilitate rapid prototyping.
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.
Tah - Control anything from your smartphone, open source, Arduino-compatible Bluetooth Low Energy (BLE) platform that can be used as a beacon, microcontroller, and HID device.
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.
The standby time is acceptable and in good condition, more than 7 days.
Maker Kits are a set of DIY open source templates for building things using IBM AI services in fun and easy ways. IBM TJBot is the first maker kit in the series. You can 3D print or laser cut the robot's body and then bring it to life using the resources provided by IBM! Additionally, you can unleash your creativity and create new recipes, using any of the available IBM AI services to bring TJBot to life! TJBot only works with Raspberry Pi.
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.
Label-free pose estimation from user-defined features via deep learning for all animals
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~
