Starfish is a pick and place machine control board built on the Raspberry Pi RP2040 microcontroller and Trinamic TMC2209 motor driver. This control board has some similarities to a 3D printer control board, but it has some unique issues to solve—including controlling solenoids and communicating with vacuum sensors. All board information is open source, and detailed explanations are provided to help you copy successfully.
You can certainly buy desktop power supplies, but they're not cheap. As the current capacity and output voltage quantity increase, so does the price. While a commercial desktop power supply is certainly worth the investment, you may want to consider a cheaper solution. Adapt an old computer power supply for use on your workbench. Computer power supplies have all the voltages you need and some very impressive current capabilities.
USB-Cereal is a powerful, fully open source development tool that simplifies testing, development, debugging and manufacturing of devices using USB-C. Using the extended capabilities of USB-C, this unique hardware saves time and effort by simplifying debugging and factory log capture, as well as firmware update procedures.
Huge, shiny, beautiful video displays with thousands of LEDs have always been out of reach of enthusiasts and small business owners due to their high cost and complexity. Pixblasters MS1 changes all that.
The basic concept of this work is slightly different from standard tools such as a reflow oven or soldering iron. Heat is provided from the bottom of the PCB.
This awesome project comes from the nV-level measurement instrument challenge launched by xDevs. The project requirements are relatively difficult and only one author has completed it. The author has open sourced all project materials and provided detailed explanations (in English).
Inspired by the EEZ H24005 programmable power supply project, which has attracted many enthusiasts with its feature set, rich user interface, DIY friendliness and completely open source hardware and software design.
The core idea of USB portable programmable instruments is to provide electronic engineers and enthusiasts with a series of low-cost, portable, network-enabled, programmable, and open source practical tools. The multifunctional USB power supply is the first of its kind and is expected to complement traditional adjustable regulated power supplies.
The author is located in an area with a lot of convective weather and hot and humid weather. I stared at it silently, and saw that the clothes to be dried came in and out five or six times a day... Weather forecast on the mobile app? Weather warning text message? It can only be regarded as a late report. I am lazy, do it myself, have enough food and clothing...
The LS1028A development board has most of the features of the LS1028A processor, built with a high-performance core, HMI functionality and TSN.
This project uses LSM6DSOX high-performance sensor and LIS25BA high-precision bone conduction sensor to control the four-axis robotic arm. By combining FMS and MLC with LSM6DSOX, the robotic arm can grab and put down items. Through LIS25BA, the vibration can be recognized and the steering gear can be controlled to complete the corresponding actions.
The hardware is independently completed by the Raspberry Pi microcontroller RP2040, which costs 5 yuan a piece. Just close a trigger design baseboard designed by KiCAD. The software is created using VSCode + GCC + Cmake. It doesn’t matter if you don’t know how to use it. The firmware is upgraded using the U disk drag-and-drop method that comes with the Raspberry Pi chip.
The current design solution uses an 8-bit ADC chip ADC08100 and a 100M bandwidth front-end analog circuit. In fact, if you want to play, you can improve the indicators and use AD9288 or the domestic alternative MXT2088. One chip has two channels and achieves a 250M sampling rate through rapid alternating sampling.
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.
A practical heating table for PCB reflow soldering. It is quite cool. It may be the most beautiful and functional heating table on the market. Parameters: The hardware is based on the ESP32PICO-D4 chip, the input power is 24V/10A, the maximum power is 200W, and the heating temperature is up to 300°C. It has Bluetooth function. If I have time later, I will develop a mobile APP to set the temperature rise curve.
This single-phase energy meter reference design is used for the measurement and registration of active and reactive energy within a directly connected single-phase two-wire network.
