Recently, Sebastian Staacks, a physicist and development engineer from Germany, created a unique electronic guestbook for his brother's wedding. The guestbook is developed based on the ESP32 Wi-Fi module. All wedding guests can log in to a simple web interface through their mobile phones, enter text messages and upload pictures. Affected by the COVID-19 epidemic, some friends cannot be present, but they can express their greetings and blessings to the couple remotely through this guestbook.

10 W isolated flyback power supply with lossless generation of AC zero-crossing signal and X capacitor discharge using LinkSwitch-TNZ (LNK3317D)
Smart charger design based on MAX1898 C program project file source code and circuit diagram
SlimeVR is a set of open hardware sensors and open source software that facilitates full-body tracking (FBT) in virtual reality. Without the need for a base station, SlimeVR makes wireless VR FBT affordable and comfortable. SlimeVR FBT provides simple, effective body and limb tracking in VR games and other applications. It utilizes high-quality inertial measurement unit (IMU) sensors and a Wi-Fi connection to a PC instead of wires, cameras or base stations to make full-body tracking comfortable and affordable. Take the lower-body suit, for example, where five trackers—one on each thigh, one on each ankle, and one on the waist—are enough to get the job done. Each tracker monitors its own rotation in space, and the SlimeVR software uses your scale and headset position to calculate joint angles and estimate limb position. In more technical terms, SlimeVR relies on absolute orientation sensors, a configurable skeleton model, and forward kinematics. The result is like having virtual Vive trackers installed at strategic locations on your body.
The MAXREFDES41# reference design is a high-efficiency, high-precision, isolated DC-DC forward converter with an active clamp, current-mode PWM controller. The converter accepts 18V to 36V DC input and delivers output current up to 3.5A at 12V . Test results and hardware files provide complete documentation for the design. The board is also available for purchase.
FRDM-KW40Z is a development platform for KW40Z/30Z/20Z Kinetis ® W MCU, supporting Bluetooth Low Energy and IEEE ® 802.15.4 for portable healthcare, wearable sports fitness and home automation devices.
PMP9750 is a CLL resonant converter reference design with an input voltage of 400VDC and an output voltage of 28V/9A. Unlike the LLC series of resonant converters, the CLL resonant converter used in the PMP9750 utilizes its output inductor to minimize the size of the resonant tank. With the resonant controller UCC25600 and bridge driver UCC27714, the PMP9750 achieves a peak efficiency of 95.7%.
14-bit, 4-20mA loop-powered thermocouple temperature measurement system using ARM Cortex-M3
The MAXREFDES1202 is a dual-phase, buck converter reference design developed using the MAX17558, MAX15019A, and MAX17552. This reference design is rated to operate over a wide input voltage range from 15V to 55V. The design can deliver an output power of 360W at 12V.
The LPCXpresso54628 development board provides a powerful and flexible development system for NXP ortex®-M4 LPC546xx series MCUs. They can be used in conjunction with a wide range of tools, including the MCUXpresso IDE.
This design implements a bidirectional, non-isolated buck-boost power converter suitable for solar microconverters, hybrid electric vehicles (HEV), and battery charging applications.
The first prize of the electronic competition, the elderly health monitoring smart watch (STM32F4 master control).
This reference design explains how to power the Xilinx Zynq Extensible Processing Platform (EPP) and peripheral ICs using Maxim's power-supply solutions.
The LX2160A development board is used to design and evaluate the LX2160A processor. It loads the standard Linux kernel board-level support packages.
This reference design provides a complete set of color RGBW LED lights controlled by ZigBee Light Link. The light has four colors of LEDs (red, green, blue, white) and is powered via USB. These LEDs are controlled by a CC2531 device running the ZigBee Light Link software stack. In order to save space and cost, the circuit board is equipped with a half-wave dipole PCB antenna.
