Many of us love reading books. Some love literature while some love educational content. eBook readers are new gadgets that are changing the reading scenario. These devices can hold a lot of content and provide a great experience. All we need to do is charge battery and keep it alive. These digital readers are great in our view. However, there might be some side effects of reading eBooks. One research of doctors of Harvard Medical School concluded that reading eBook before sleeping is harmful.
Large Hadron Collider (LHC) is a very famous scientific machine. It is one of the world’s biggest particle collider. LHC performs many big experiments. Discovering Higgs Boson is one of them. They are to understand our universe and better. Scientists are on the verge of finding Higgs Boson. They have already found its energy region by two separate experiments. The scientists have discovered two new particles named Xi_b’– and Xi_b*–. It is a very noteworthy discovery in the field of science.
Military technology and engineering are always better and ahead. They always have a good budget and bright minds at their disposal. They always show us first class powerful and awesome gadgets. If we look back at history, the US Military is one of the key element in the development of the Internet. After good research and show of really cool Rail Gun, US Navy starts LaWS (Laser Weapon System). This is the first phase project. We assume that we will be seeing laser guns very soon.
Welding metals is a process requiring a huge amount of power. Welding requires a good power supply with good voltage and current. The voltage helps to create and maintain arc while current is required to create heat and melt the metal. It means both base metal and electrode or filler metal. Here we have compiled some information from our experience on arc welding requirements. This is to help the starters and interested people.
Since I was a small boy I had a knack of technology and science. It was interesting to see people melt and fuse them together using a thin rod and electricity. During high school, I studied and learned the building process through various sources. I also experimented with small transformers for a long time to get good knowledge about them. Finally, after high school, I managed some money and made it. So this is my homemade arc welder build guide for everyone.
We have a full step by step guide on building homemade stick welder using microwave oven transformers (MOT). Welding is amazing and it is a great skill to have. Thus I want to share some important information with everyone to help save and good welding. So I have written this article as arc welding guide to help home welders and hobby welders. Arc welding requires a few important pieces of equipment, knowledge, and skill which I will explain.
A lot of people suffer from cardiovascular diseases. Many people with heart problems require a pacemaker for their survival. Most pacemakers have a battery that lives a long time. But after a while, it needs replacing. Replacing means requirement of the new surgery. A better thing has now come that can save people from this. It is the new battery less pacemaker that runs on your own heartbeat. Scientists of Switzerland have developed this new device that can help millions of people.
ALS Ice bucket challenge is famous on the internet since few days. It is getting pretty popular among many people including social activists, superstars, and philanthropists. Many people might think that this is just a popularity stunt. In reality, this is actually a good campaign that is creating awareness. Hence many people are knowing about ALS. Making the disease popular or creating awareness is the main reason why people are doing this challenge.
Inverters and UPS are pretty confusing to most people. Basically, they are power backup devices. They use a big rechargeable DC battery which is used to provide AC power when needed. Most of the times, Inverters are used in house and office to supply electricity during a power outage. Many households have Inverters but at the back on the control panel, there is a switch usually. It is to change the mode of Inverter to UPS. It is quite interesting so we want to share some knowledge on the UPS mode Vs inverter mode.
We all live in a world obsessed with technology. Almost everyone has a mobile phone these days. Teenagers mostly indulge in social media like Facebook, Twitter, Instagram, etc. The basic lifeline of all this communication is the “Internet”. Most people use WiFi from Broadband connections or mobile data. No disaster comes with prior notice. Imagine a situation after a disaster where there is no internet, mobile network, landline or any other digital communication. In such a case, a simple DIY AM voice transmitter can be a lifesaver.
