A Cost-efficient Super-Cascode SiC Switch

Researchers have created a high voltage and high frequency silicon carbide (SiC) power switch that could cost much less than similarly rated SiC power switches. The findings could lead to early applications in the power industry, especially in power converters like medium voltage drives, solid state transformers and high voltage transmissions and circuit breakers. Researchers at North Carolina State Univers ...

ESP8266 GMail sender

Hello and welcome to my first Instructable. I will show you how to send emails from any ESP8266 wifi module using Gmail server. This instructable relies on Arduino core for ESP8266 WiFi chip, which makes a self-contained microcontroller from it (no need of AT commands and master devices). You can connect sensors and get notified by email about changes. Before we begin Required hardware: Any ESP8266 (I'm usi ...

Tibbo – MQTT Library Demo

About The Application To illustrate the use of the MQTT library, we have created two simple Tibbo BASIC applications called "mqtt_publisher" and "mqtt_subscriber". In our MQTT demo, the publisher device is monitoring three buttons (Tibbits #38). This is done through the keypad (kp.) object. The three buttons on the publisher device correspond to the red, yellow, and green LEDs (Tibbits #39) on the subscribe ...

The Web Bluetooth Security Model

Web Bluetooth is a developing JavaScript API to allow websites to communicate with Bluetooth devices. Sites ask the browser to show a list of nearby Bluetooth devices matching certain criteria, and the user either picks which to grant access to or cancels the dialog. As you might expect, there are security risks here. When deciding whether to ship the new API, we should look at several kinds of attackers an ...

Collecting GPS Data Using GPS Module With Windows IoT

Story In this tutorial we will demonstrate how GPS data can be collected from a serial GPS module. We are using an Andoer u-Blox NEO-6M GPS module, which has excellent GPS capabilities. One of the NEMA sentences that it collects includes the GPGGA sentence which provides essential fix data. We'll show you how to develop an application that will collect the serial data in the form of a sentence, which is the ...

An isolated analog output for Arduino Uno

This project uses the Arduino PWM Uno or other systems to realize a fully isolated analog output with a range of 0-5 volts or more, changing only the reference voltage. Introduction This project completes the series of my articles about the Arduino analog I/O with the aim to use it as a controller of small automation systems. In control systems of the industrial plants it is always advisable to isolate both ...

Internet-of-Things Power Meter

Description The Internet-of-Things Power Meter (IPM) is a device fixed on top of the regular household power meter that provides detailed information about the electricity usage. Modern power meters have a LED blinking every time a watt-hour is used, the IPM detects these flashes using a light sensor, counts them, saves the values to an SD card. Later the data is stored to the cloud. Usually power companies ...
