Climate Change: The Complete WIRED Guide

Then in late 2019, Australia suffered an unprecedentedly brutal fire season, giving the world perhaps the most dramatic manifestation of the climate crisis to date. In an average year, 1 percent of Australia’s famous eucalyptus forests might burn. But in the 2019–2020 fire season, 21 percent went up in flames, obliterating whole ecosystems and likely dooming many species into extinction. The conflagrations were so bad, models predicted it would be 80 years before something like that happened. Meanwhile, at the Earth’s poles, landscapes are transforming quickly and dramatically. …

Tethered to My 1st Mobile Phone

I was a manager at at a high tech government contractor in the early 90’s and I remember sitting working on my very large mainframe computer when my boss enters the room announcing he has a surprise for me. He sits on my desk this very large 12″ x 6″ x 10″ contraption that appeared to be some sort of phone.  Quite heavy for me.  I was intrigued to say the least.  We have heard about mobile phones being tested and tried several places but mainly being used …

Amazon Smart Plug

The majority of the people are able to remember the old electric timers we would be so excited to plug into our lamps before we left for vacation.  My mother used to say this is so anyone watching our house won’t know we are not home.  She would sit it to come on at dusk and off about 11pm.  It was not easy sitting the time and power failures would really mess them up.  Now we have the new and easy smart plug from Amazon which handles away …

Will Your Friendship Survive This Versus Game?

  Competitiveness is one of my stronger qualities. I’m still trying to decide if that’s a good or bad thing. My close friends and family may favor the latter. While I contemplate my penchant for winning, check out this hilariously named competitive speed game on Tindie! The ButtSnap, yes that’s the real name, is a simple competitive speed game meant to be played by two players. This product is a mini PCB with two buttons, one for each player, and three LEDs, the center LED is the trigger …

Observatory Dome Sliding Door Powered By Arduino

Advertisement Observatory doors are quite heavy and weigh several kilograms. This requires a strong, automated mechanism to move them. Such was achieved by employing a commonly used DIY board that consumed only a fraction of household power. Image credit: https://blog.arduino.cc A dome-shaped observatory housing an optical telescope is often built on a high altitude location, where the surrounding air is much clearer as compared to that near the land and where a good view of the sky can be obtained for accurately recording celestial observations – without any …

How Does Bandwidth Affect Website Performance?

Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at How Does Bandwidth Affect Website Performance? Today we’re going to discuss something that everyday users and new website owners sometimes find confusing i.e. bandwidth. How much bandwidth is enough, and what happens when you have too little. Is it possible to squeeze data through if it’s insufficient? Can you get more? Before we get into those questions, it helps to explain what bandwidth is and how it works. What is …

Enginursday: The Decade of Pi

In a pre-cursor I doubt anyone reading this needs, Raspberry Pi is a foundation out of the UK that produces a set of ultra-inexpensive computers capable of running operating systems at previously-unheard-of pricing. The boards these days range in price from $10 to $60. They marked a resurgence in the phrase “single board computer,” and have become a new benchmark in performance for a number of incredible uses. For me, the Raspberry Pi had an interesting effect: my friends suddenly understood what I did. Working at SparkFun during …

Create A GUI Program For Raspberry Pi And Arduino

Advertisement This article describes the procedure to set up Arduino as a slave device, which gets all control signals from Raspberry Pi running a Python program. The program presented here provides simple steps to interface Raspberry Pi and Arduino. Arduino as a slave can also be used to control electrical devices including LEDs and servos. Raspberry Pi, a credit-card-sized computer, has a good amount of computing power but lacks the ability to connect to field devices. This is because it is a 3.3V device and has no analogue …

What is Virtual Reality (VR)? The Complete WIRED Guide

When actual VR took root in our minds as an all-encompassing simulacrum is a little fuzzier. As with most technological breakthroughs, the vision likely began with science fiction—specifically Stanley G. Weinbaum’s 1935 short story “Pygmalion’s Spectacles,” in which a scientist devises a pair of glasses that can “make it so that you are in the story, you speak to the shadows, and the shadows reply, and instead of being on a screen, the story is all about you, and you are in it.” Anatomy of a Headset What …

Automatic Anchor Light

Advertisement Federal and international regulations require boats to carry lights between sunset and sunrise and during conditions of restricted visibility. The number and colours of the lights vary with the size of the vessel. Many commercial vessels carry special lights that identify them to the others. This is important because right of way depends on the types of vessels involved. Tugs and commercial fishing vessels have the right of way over sailboats, which have the right of way over ordinary power vessels. Fig. 1: Anchor light position at …

What Is the Internet of Things? A WIRED Guide

Most of the early smart home inventions used automatic controls, making it possible to turn something or off without lifting a finger. But they didn’t connect to anything else, and their functionality was limited. That would begin to change in 1983 when ARPANET, the earliest version of the internet, adopted the internet protocol suite (also known as TCP/IP). The protocol set standards for how digital data should be transmitted, routed, and received. Essentially, it laid the groundwork for the modern internet. IoT Through the Years 1990 John Romkey …
