Test application for the FPGA Tibbit in the smart LED controller configuration
https://www.electronics-lab.com/test-application-fpga-tibbit-smart-led-controller-configuration/
This application example shows how to connect and use RGBW LED stripe with TPS hardware platform. The main difficulty is that LEDs have their own color generation circuit inside. New FPGA Tibbit #57 can generate fast PWM signal, which is needed for proper LEDs operation. Also, the topic shows the main advantage of FPGA technology. […]
Arduino Wiring, A New Choice for Developers On Windows 10 IoT Core
https://www.electronics-lab.com/arduino-wiring-new-choice-developers-windows-10-iot-core/
Last year, Arduino and Microsoft announced a strong partnership and Windows 10 became the world’s first Arduino certified operating system. This partnership made the creation and innovation much easier with the hardware capability of Arduino and the software capabilities of Windows. Early this month, Arduino Wiring became a new programming language for Windows 10 IoT […]

Arduino radar using sound waves
https://www.electronics-lab.com/arduino-radar-using-sound-waves/
A radar system uses high frequency radio waves for object detection. A high-power RF pulse is transmitted into space and its echo reflected off from an obstacle is recorded. By computing the time elapsed between the transmitted and reflected pulses, and knowing that the electromagnetic wave propagates at a constant speed of light, the radar […]
Using VL53L0X With Arduino to Measure Height
https://www.electronics-lab.com/using-vl53l0x-arduino-measure-height/
Usually, when measuring a child’s height at home, a mark is drawn on the wall then the height is measured using a measuring tape. This process is not always easy and it may has low resolution. In an attempt to simplify this procedure, a new project was developed using an Arduino and a distance sensor. […]

Reverse engineering a server CPU voltage regulator module
https://www.electronics-lab.com/reverse-engineering-server-cpu-voltage-regulator-module/
Andy Brown wrote a detailed article on reverse engineering a CPU voltage regulator: A recent ebay fishing expedition yielded an interesting little part for the very reasonable sum of about five pounds. It’s a voltage regulator module from a Dell PowerEdge 6650 Xeon server. I originally bought this because I had the idea of salvaging […]
Sonicare toothbrush teardown: microcontroller, H bridge, and inductive charging
https://www.electronics-lab.com/sonicare-toothbrush-teardown-microcontroller-h-bridge-inductive-charging/
Ken Shirriff did a teardown of a Sonicare electric toothbrush: The photos below show the top and bottom of the toothbrush internals. I expected to find a simple, low-cost mechanism, so I was surprised at how much complexity there was inside. The vibration mechanism (right) is built from multiple metal and plastic parts screwed together, requiring […]
