This posting is a collection on trends and predictions for year 2021. The year 202 was grappled with fear of infection, incredible loss of loved ones, financial stress, isolation and fatigue from constant uncertainty to name a few. Many people expect that 2021 will mark a turning point. Heading into 2021, technology — both new →
For decades, CES® has marked the start of a new year, setting the tone for the industry with inspirational innovations and influential insights. This year CES 2021 was a digital venue showed newest innovation in consumer electronics. It had some 1900 virtual booths, several peripheral product showcase. Here are some links to reports on the →
Error-correcting code memory (ECC memory) is a type of computer data storage that can detect and correct n-bit data corruption which occurs in memory. ECC memory is used in most computers where data corruption cannot be tolerated under any circumstances, like industrial control applications, critical databases, and infrastructural memory caches. ECC protects against undetected memory →
In electronics, desoldering is the removal of solder and components from a circuit board for troubleshooting, repair, replacement, and salvage. There are many techniques how to desolder. Check out videos How to Desolder Through-Hole Parts, Why Some Joints are Difficult and Desoldering Components – Tips and Tricks. Desoldering tools and materials include the following: Solder →
A grid-tie inverter converts direct current (DC) into an alternating current (AC) suitable for injecting into an electrical power grid, normally 120 V RMS at 60 Hz or 240 V RMS at 50 Hz. Grid-tie inverters are used between local electrical power generators: solar panel, wind turbine, hydro-electric, and the grid. They range from small →
The AC output frequency of a power inverter device is usually the same as standard power line frequency, 50 or 60 hertz. An ideal power inverter should generate accurate 230V AC 50 Hz or 110V AC 60 Hz power with sine wave waveform. A less ideal inverter typically generates square wave or “modified sinewave” waveform →

The 10 smartest Ricky Gervais tweets about religion https://inktank.fi/the-10-smartest-ricky-gervais-tweets-about-religion/ British comedian Ricky Gervais always has a lot to say. Sometimes he says it on Twitter and often it’s about the ludicrous nature of religion. Here are 10 of his finest philosophical moments in a 140 characters or less. →
Sometimes devices sold as power inverter that claim to convert 12V to 230V AC (or 110V AC in USA) are not inverters at all, but DC/DC converters that output DC. I would say that calling such device “inverter” is not right, even though it might work with some originally mains powered devices. I have one →
A relay power inverter converter simple and easy inverter make circuit to convert 12V to AC voltage that can drive some small 230V AC loads like some low power lamps (LED or fluorescent energy saving bulbs). It is often advertised as a simple and easy electronics diy projects make at home. The basic idea of →
