ADALM2000 is a 9-in-1 portable test and measurement instrument launched by ADI.
ScopeFun is an open source all-in-one instrumentation platform. It includes oscilloscopes, arbitrary waveform generators, spectrum analyzers, logic analyzers and digital pattern generators.
Nowadays, almost all circuit boards use surface mount packaging, so I have always wanted to DIY a chip placement machine. After searching online for a long time, I finally decided to use the open source OpenPnP. The hardware and software are both open source.
Intel has open sourced a car with a total parts price of less than 50 US dollars, which costs about 350 yuan in total. With a mobile phone, it becomes a self-driving car.
ODrive is a high-performance FOC servo driver based on STM32. It can drive two brushless motors at the same time. In the early days, it was widely used in the design of 3D printers or homemade CNC lathe electrical systems. The well-known geek James Bruton used it as most of his own To make the core unit of the robot servo drive, Stanford's previous open source 8-degree-of-freedom quadruped robot Doggo also used Odrive as the core driver.
Amethyst is a classic home computer developed by Matt Sarnoff. It has an integrated keyboard, can generate sounds and images, uses the Forth programming language, has image and voice commands, a debugger and screen editing functions.
This is an original work by netizen jiezhi320 who participated in the RT-Thread application competition. In 2015, jiezhi320 made a version of hardware based on stm32f405rgt6. However, due to the high CPU usage of the UKF algorithm, the author migrated it to imx-rt1052, in order to leave enough resources for everyone to develop in-depth for model friends.
The Pandora McNado smart car based on Rt-Thread is composed of chassis, drive, battery, Bluetooth, APP control, omnidirectional wheels, etc.
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.
Based on ESP32 and ATtiny861 to build a Nintendo NES game emulator handheld console with complete materials for making the project
A simple oscilloscope made of STC8A8K MCU. The microcontroller uses STC8A8K64S4A12 working at 27MHz. The display uses a 0.96 OLED with a resolution of 128x64. This oscilloscope project is easy to start and covers the necessary measurement functions. Supports normal mode, single mode, and automatic mode. It has trigger mode selection, such as level trigger, and comes with saved settings. Mini-DSO input is single-channel mode, and the second/division size can support a variety of: 500ms, 200ms, 100ms, 50ms, 20ms, 10ms, 5ms, 2ms, 1ms, 500us, 200us, 100us, and the voltage acquisition range is 0 to 30V. The sampling rate can reach 250kHz@100us/div.
Built-in gyroscope, buzzer, supports multiple fast charging protocols, 128x64 OLED screen, standard T12 fixed bayonet. Regarding the problem of grounding the soldering iron, you can use the PD power supply of Mac and prepare a triangle extension cable to solve the problem perfectly. Or using a power bank directly is not a big problem.
This is an open source work by netizen aziddy, based on the classic Adafruit Feather 328P development board (the MCU master is Microchip's ATmega328P) and a mini electronic game console with a 128x64 OLED screen
This dice mainly consists of an ESP8285-01F, six PCBs and 54 LEDs. Its structural design is very clever, and the exquisiteness of the structure is also reflected in the production process.
An ultra-mini frequency probe designed by foreign expert David Johnson. This frequency probe can help you debug the circuit by displaying frequency and voltage. It can measure periodic waveforms from 1Hz to 5MHz with an accuracy of 0.3%. Of course, it can also be used as a voltmeter. Use it to tell you the current voltage value.
This project uses STM32F103RET6 as the main control, and is modified based on ST's official CMSIS-DAP project to achieve offline and read-protected programming (because the project currently only has F103 series offline programming requirements, so only F103 programming is temporarily added. write algorithm).
mini-violin is an open source project for violin design, and the circuit schematic is quite simple. The ATtiny85 controls two LEDs and a piezo buzzer, in addition to a button to switch songs. What's particularly interesting is that the violin strings are connected to the analog inputs of the microcontroller so that they can be controlled by contacting conductive materials. Come play the violin.
The MicroByte is a tiny console capable of running games from the NES, GameBoy, GameBoy Color, Game Gear and Sega Master systems, with all components designed into this 78 x 17 x 40 mm package.
With voice recognition function, you can use voice to search for weather, as well as radio, temperature and humidity, calendar and other functions.
Watchy is a completely open source and customizable e-ink screen watch. It uses ESP32-PICO-D4 as the core, has WiFi and Bluetooth LE connectivity, and is compatible with Arduino, MicroPython and ESP-IDF. The 200x200 pixel resolution e-paper display is clearly visible in bright sunlight and has ultra-low power consumption.
