Codebender Arduino IDE

Do you want to experiment with Arduino, but do not want to install Arduino IDE or not like it? Not where is another way to do Arduino coding: web-based, fully networked on-line developer environment called Codebender. Codebender is an in-browser dev environment that can store your code, copy from other users, and upload it to →

ESP8266 programming tools

The ESP8266 is the answer to “I want something with Wifi.” It’s basically the answer to everything IoT to so many engineering problems that have plagued the hobbyist and commercial world alike. The chip is a processor  (80MHz Tensilica) with integrated RAM, some ROM, and a WiFi radio. It’s CHEAP, like $4/ea cheap! Or $5 →

AD9850 scalar network analyzer

A network analyzer is an instrument that measures the network parameters of electrical networks. Today, network analyzers commonly measure s–parameters. Full featured network analyzers are expensive instruments, and sometimes a simpler. Scalar Network Analyzer (SNA) is a simpler form of RF network analyzer that only measures the amplitude properties of the device under test.  SNA is →

Arduino AC measurements

Sometimes there is need to measure power going to different devices. Measuring DC power consumption is pretty easy, but when you try to do the same for AC circuit, things start to become complicated. How to Measure Electrical Power article will discuss best practices for making electrical power measurements, starting with power measurement basics and →
