Based on the modular IoT framework, NXP provides an IoT use case-specific integrated development experience (IDEx) suite to accelerate IoT system development with pre-integrated, comprehensive and fully documented out-of-the-box IoT system solutions.
Open Book is an open hardware device for reading books in all languages of the world. It includes a large screen and navigation buttons, as well as audio options for accessibility and ports to expand its functionality. Its fine screen printing aims to demystify Open Book's own design, breaking down for curious readers how the book works and how they can create one for themselves.
Have you ever wanted to install a security camera in your home, garden or office? Although commercial Wi-Fi security cameras on the market are not expensive, if you want to install multiple ones in different scenes or rooms, it will cost a lot of money. Young engineer Max can develop a wireless security camera based on Espressif's ESP32 chip with only $15.
The author noticed that the AC line frequency changes in spans of 0.4 Hz and periods of several minutes, so I wanted to examine long-term changes in AC line frequency and voltage. This is a project to build a line voltage frequency monitor. It is not a complete instrument but a simple measurement adapter designed to be embedded in some measurement system with a PC or microcontroller.
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.
This is a reference design for a wireless charger. The working principle is: power transmission between objects through electromagnetic induction. A fully analog RL78/G11 microcontroller, ISL28006 current sense amplifier and HIP2106A MOSFET driver are used.
The i.MX RT AVS solution based on Alexa Built-in MCU is a turnkey hardware and single-source software solution for adding voice control with Alexa.
Have you ever thought about attaching an inertial measurement unit (IMU) to an object to track its posture and motion? Tracer provides high-performance, safe, reliable and low-cost object tracking. Tracer can be easily attached to objects using Velcro. It can tilt and track rhythm as the bike's frame tilts, it can record the number of shots taken with a tennis racquet, and it can even differentiate between topspin and chip shots. Let your imagination run wild and explore more interesting applications of Tracer!
The LS1012A-RDB is a compact tool that can be used to evaluate LS1012A solutions for consumer electronics, industrial control and networking applications.
Isolated 4-Channel Thermocouple/RTD Temperature Measurement System with 0.5°C Accuracy
A phase compensation algorithm is used to compensate for the additional phase delay introduced by the multiplexed ADC, thereby producing an effect equivalent to a synchronously sampled ADC.
Using ADuC7060/ADuC7061 precision analog microcontroller to build a thermocouple temperature sensor with cold junction compensation based on automotive SENT interface
The Microchip SAMRH71F20-EK Evaluation Kit is a hardware platform for evaluating the SAMRH71F20 microcontroller.
Powered by Microchip's MPLAB® HARMONY integrated development platform and other commercially available development environments, the evaluation kit provides easy access to the Microchip RadHard SAMRH71F20 microcontroller and its aerospace-specific feature set and shows how to integrate the device into a custom design.
The Stanford Pupper is a four-legged robot designed to help K-12 and undergraduate students engage in exciting robotics research.
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 project originated when the author purchased an electric motorcycle for his daughter and replaced its original lead-acid gel battery with a lithium battery pack. Due to the lack of smart, cheap and easy to configure lithium battery management systems on the market, the author decided to make one himself.
