My initial idea for the "Badminton Training Device" project was to sense the form and intensity of the racket swing, whether it hit the badminton and where it was hit, etc., record the quality of all swings after a game, and combine it with the host computer to make a badminton shot. Play the practice analysis system. The MLC and FSM modules in LSM6DSOX can analyze and identify actions, which greatly reduces the data processing requirements of the MCU and can save resources to complete prompt or record functions.
ADALM2000 is a 9-in-1 portable test and measurement instrument launched by ADI.
Open sourced by Bilibili up, DCDC-LDO secondary step-down power supply, tc1047 for cold-end compensation, built-in curve fitting calibration function, and supports 65W gallium nitride charger.
ESC is the abbreviation of Electric Speed Controller, that is, electronic speed controller, or ESC for short. The author is Benjamin Vedder, so it is called VESC. You may have heard of it, which is Benjamin ESC. This project is mainly divided into several parts, VESC firmware, bill of materials, VESC hardware, and VESC tool software. It is a very complete software and hardware project, and the supporting software is also excellent.
A low-cost PD-powered reflow soldering heating plate that uses a cermet heater (MCH) instead of a PCB heating plate for heating. It has a USB Type-C input port and can be powered by a 60W (65W) PD power supply.
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 cost of the board should be less than 50RMB, and it provides a lot of information, which is very suitable for novices to use as a development board to learn Linux.
There are three boards in total, USB, FPGA and Sensor board. The FPGA board features a Lattice Crosslink NX LIFCL-40 and the required power regulator, and the USB board features a CYUSB3014 USB 3.0 SuperSpeed controller.
This open source ferry robot has unique functions such as the anti-interference standing ability of a tumbler and automatic roll-up.
SmartKnob is an open source input device with software-configurable stops and virtual locators. The brushless gimbal motor is paired with a magnetic encoder to provide closed-loop torque feedback control, allowing the feel of the detent and stop to be dynamically created and adjusted.
This is a single channel LiDAR demo board that allows you to check the operation of a high-speed optical front end using the LiDAR ToF range technology. The measurement distance can be up to 50m. The LiDAR ToF architecture can be applied in the automotive as well as consumer and industrial machinery sectors.
This is a reference design for Totem-Pole bidirectional power converter for electric vehicles. By using SiC MOSFET, it can operate at high switching frequency, achieving high efficiency, small size and lightweight.
ScopeFun is an open source all-in-one instrumentation platform. It includes oscilloscopes, arbitrary waveform generators, spectrum analyzers, logic analyzers and digital pattern generators.
Bllimpduino 2 is a very low cost open source autonomous airship. It consists of Arduino M0 airship controller board and on-board WIFI and laser sensors. Two vector differential thrusters and one lift thruster. The design is simple, yet exciting.
This 100 W reference design highlights the excellent power quality and high frequency performance of the half-bridge (HB) driver using the ICL5102 with the economical CoolMOS™ P7 series. The design takes full advantage of the applicable frequency range of the HB driver to create Highly compact LCC transformer. This transformer integrates the series inductance of the LCC resonant tank. Relying on this high power density transformer design, the high frequency operation capability can drive system cost and size reduction.
This is a single-channel LiDAR demonstration board that allows you to check the operation of a high-speed optical front-end using LiDAR ToF scope technology. The measuring distance can reach 50m. LiDAR ToF architecture can be used in automotive as well as consumer and industrial machinery.
Design secure POS with PCI and EMVCo, NFC, chip card and magnetic stripe readers using NXP technology.
