This is a continuation to my Power inverter designs post. The first post was about general details of inverters and square wave inverters. Because square wave inverters are not suitable for many applications. The next better inverter category is so called modified sine wave inverter. Modified sine wave inverters are less complicated than sine wave →
A power inverter, or inverter, is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The inverter does not produce any power; the power is provided by the DC source. This document is collection of information on power inverter technology and gives links to DIY circuits – both good →
Electronics prototyping is an important part of electronics device development. Prototyping means to build and test an early version of) an electronic circuit. Prototyping your product is all about learning. Each time you create a prototype version you will, or should, learn something new. Start with the most simple, low cost way to prototype your →
I saw an advertisement video of LED hat on Facebook some days ago. This kind of had might not be the best idea to wear on many parties, but maybe could have some uses for advertisement purposes. This kind of LED hat is something that makes hacker mind spinning. The hat had wireless connection so, →
We are living in the middle of the emergency over coronavirus all over the world. The reactions to the COVID-19 pandemic and its effects on societies and economies around the world cannot be understated. Because an estimated 15% of COVID-19 patients require hospitalization and 5% require intensive care (Z. Wu and McGoogan 2020), the ongoing →
A signal generator is an electronic device that generates repeating or non-repeating electronic signals in either the analog or the digital domain. These generated signals are used as a stimulus for electronic measurements. There are many different types of signal generators with different purposes and applications. For analogue signal generation I have used for very →
Years ago you had to either build your own signal generator or buy usually a quite expensive signal generator. Lately there has been a push for very cheap ($15-25) digital function generator kits available from China. I wrote about some interesting function generator devices few years ago, and here is a closer look to one →
I have made earlier a post on electrical car charging cables and charging stations technology. This s a continuation posting related to it. This posting links to DIY projects related to electrical vehicle charging cables. Those cables are quite expensive, so some DIY persons have tried to make their own versions. Some even claims have →
happen to own IKEA Bekant motor adjustable table. It worked nicely for around years, and served well as my working table. Though there are only simple “Up” and “Down” buttons installed by default, it works OK. But one day I found out that some day moving the table up and down did not work anymore. →
DMX512 (Digital Multiplex) is a standard for digital communication networks that are commonly used to control stage lighting and effects. It was originally intended as a standardized method for controlling light dimmers up to 512 dimming channels. The first standard version was created in 1986, with subsequent revisions in 1990 leading to USITT DMX512/1990, ANSI →
