Guns fall under the category of weapons. They are small and tubular, though there can be alterations in size and type depending on the model of the gun and the situation they’re used for. They have a safety click, which once removed, has the ability to shoot out bullets- which can injure, and even kill.
Guns can be of various types. These include nerf guns as well as Taser guns. This gun have recommended gun safes for various kind of guns here.
Guns safety rules and regulations are always considered in order to avoid accidental discharge or negligent discharge, or to avoid the consequences of malfunctions in fire arms. If you are carrying so many guns, then go for Winchester Big Daddy gun safe without investing further on gun safes.
The purpose of gun safety is to minimise injuries or the risks of unintentional death caused by improper possession, storage or handling of these fragile yet dangerous weapons. The best way in order to handle a fire arm requires, immense care and alertness which if overlooked, can lead to a hazardous outcome.
The rules of gun safety are as follows:
Ranges and organized shoots must be carried out, so that the person who has a hold on the gun can conveniently understand when to carry out the firing and when to stop. There’s a difference between aiming the gun at a target, and predicting the distance at which it might hit.
The operating principle works on compressed gas which is confined in the barrel, forcing the bullet out of the gun to shoot out with immense force. In firearms, the high-pressure gas is generated by combustion, usually with gun powder.
Ranges may limit the type of ammunition used or might shoot more powerful rounds than a range is actually equipped to handle.
Ranges must be designed keeping safety in mind, including the user of proper backstops for the intended type of shooting.
Always keep the gun unloaded when not in use.
Aim the gun right at the target and not even a little way off, since once shot, the force of the bullet is more likely going to make you stumble or mess the shot even more than usual.
Always treat the gun as tough it’s loaded.
Always keep your finger straight and off the trigger until you’re ready to shoot.
Be sure of your target and what’s behind it.
Never point at your target or anything at all in the environment, if you’ don’t have the intention of destroying anything.
Be sure the barrel is clear of obstructions before loading and shooting.
Don’t rely on the gun’s safety to keep it from firing. You’re the one who is truly responsible.
If your gun fails to fire when the trigger is pulled, hold your shooting position for several seconds; then with the muzzle pointed in a safe direction, carefully unload the gun.
Be aware of your surroundings when handling guns so you don’t trip or lose your balance and accidentally point and/or fire the gun at anyone or anything.
Always keep the gun unloaded until you are ready to use it.
Listen and do what the Range Master tells you to do.
Uncase and case your gun at the shooting bench, never behind the safety line.
Always keep the barrel pointed down range.
Always keep the gun on safe until you intend to shoot.
This super simple project is a great introduction to Arduino programming. This traffic light controller uses a red, yellow, and green LED to re-create a traffic light on your breadboard, and give you the opportunity to hack the code in order to adjust the output, timing or even the sequence itself. It’s a wonderfully easy way to get your hands wet with simple coding, and learn to modify it to fit your goals for a particular project.
2-Arduino-Powered Temperature Controller
On the Pacific Coast of Mexico, where I live, the average year-’round temperature hovers at a pleasant 70-degrees, making central air or heat a relatively rare occurrence. I’m not complaining, and generally the temperature doesn’t warrant any sort of need for control, but certain instances (growing plants indoors, cooling items in a mini-fridge to a set temperature, controlling surface temperature of a reptile cage, etc.) could require the need for a more constant temperature. With an Arduino, and a few parts, you’ll be well on your way to creating your own instead temperature control device instead of forking over two or three times as much (or more) on a pre-built model.
3-Re-Create the Arcade Classic “Pong”
For retro game lovers, former Atari 2600 owners, or just someone looking for a cool project that utilizes exactly none of the resolution of your new 4k tv, you can re-create the classic Atarti game Pong using just a few easy-to-find parts, and an Arduino. This project uses a lot of the parts found in most Arduino starter kits, and uses them to make two controllers as well as a fully-functioning Pong game that you’ll output to your television screen through a standard composite cable.
4-Pulsating LED Cube
This little 4 x 4 x 4 cube uses super bright LEDs as well as some mutliplexing to control the lighting from a single Arduino Uno board. If you haven’t quite mastered soldering, this is good practice, and it’ll prove especially useful as you foray into building projects that are a little more permanent than the starter projects you’ve most likely been building to this point. In addition, you can program the cube to do some really cool stuff once you’re finished.
5-Companion Cube Mood Lamp
This Portal-themed mood lamp uses a square glass jar to create a color-shifting display that looks incredible in any dark room. The project itself is ideal for an Arduino beginner and most of the parts are included in your Arduino starter kit. Creating the lamp is a great starting point for beginners as the wiring, build and the code are relatively simple and a great way to slowly build into more advanced projects by learning some essential beginner’s electronics skills that you can call on later.…
electricalworldComments Off on The World’s First Solar Powered Cricket Stadium
Cricket is the most popular sport in India, and the M. Chinnaswamy Stadium in Bangalore one of the country’s best-known cricket stadiums. On match days, up to 40,000 spectators come to the stadium, which was built in 1970. Now the M. Chinnaswamy Stadium has now been converted into a ‘green’ stadium.The project was completed in just 50 days.
A 400kW Grid Interactive Solar Power Plant has been installed on the roof of the stadium. As per the design, this grid can easily power the entire stadium lighting except the huge high-intensity floodlights.
The stadium spends around Rs 1 to Rs. 1.2 crores on electricity bills for using about 18 lakh units of power annually. The new initiative will bring down this cost significantly and is expected to generate 6 lakh units of solar power annually, utilizing a portion of it and also selling the surplus.
A modern plant installed on the roof of one of the stands helps collect up to 35 million litres of rainwater every year, which can be used for the sanitary facilities or to water the playing field. An optimised waste disposal system ensures that the trash left behind by spectators is disposed of in an eco-friendly manner and recycled. A solar system on the roof of the eastern stand provides clean energy for the visitor areas and for the changing rooms. The M. Chinnaswamy Stadium is the first cricket stadium in the world to be powered by solar energy.
The project, costing Rs. 4.5 crore, was commissioned in February this year and KSCA(Karnataka State Cricket Association) is expected to break even in just four years. Not only this, it will also be able to generate revenues of Rs. 70-80 lakhs every year with the power it generates.
The maintenance of solar systems, such as the one in the Bangalore stadium, is cost-effective, and surplus energy from the roof of the stand can be fed directly into the city’s power grid. While the installation costs will be recouped in just four years, the environment is already benefiting, as the use of solar energy helps save 600 tonnes of CO2 per year.…
At the cost of sounding unscrupulous, the following are some suggestions made by experts on how to fool a smart meter:
1.) Spreading Malware To the Smart Meter’s Network
With access to the smart meter’s programming codes, it is possible to connect with all other smart meters in the network that have the same brand. David Baker, director of services for IOActive, a Seattle-based research company , demonstrated this possibility when he designed a virus that could replicate itself in other smart meters and enable a hacker to shut down the system remotely. In simulations, Davis was able to show that if his malware were to be released in a location where all the houses were fitted with the same brand of smart meter, it could spread to 15,000 homes in 24 hours.
2.) Measuring The Smart Meter’s Electrical Consumption
Inside smart meters are sensors that measure energy consumption. Under the old mechanical meters, interfering with the meter’s ability to report accurately has been the means of many unscrupulous individuals to save money on electricity, like by the use of magnets. The old method used with analog meters may not be difficult to use in fooling the old meters but the new generation of smart meters were designed to protect against such automated methods.
3.) Attacking A Smart Meter’s Memory-Through Hardware
If a smart meter hasn’t been built with protective features, inserting a needle on each side of the device’s memory chip can do the trick. The needle intercepts the electrical signals in the memory chip. From these signals, a device’s programming can be determined. If security features are in place, it is still possible to obtain the data through customized tools.
4.) Using A Digital Radio To Hack a Smart Meter
The two-way radio chip in a smart meter allows the device to be read remotely and receive commands over the network. A hacker, who has cracked the smart meter’s programming, can use security codes from the software in the chip to get on the network and issue commands.
5.) Accessing The Meter
Another method of hacking the smart meter is through a wireless device. Using a software radio programmed to mimic a variety of communication devices, a hacker can listen in on wireless communications in the network and guess over time how to communicate with the meter. Another method is to steal a smart meter and reverse-engineer it; although inexpensive, the process would require a good knowledge of integrated circuits.…
BORED HOLE & NEEDLE
This method involves direct tampering by boring hole or holes anywhere in the meter’s plastic casing. The tiny hole is then inserted with a needle which will stop or slows down the spinning aluminum dial. This tampering method can be easily spotted by the meter readers of the power company.
TURNING THE METER UPSIDE, DOWN
Turning your meter upside down could be a way to stop the meter. But this is very obvious and will be short-lived because the company’s meter reader shall call the maintenance to fix it.
REVERSING THE METER
The meter can be stopped from running or even reverse its motion to reduce the actual consumption reading. This can be done by using the so-called CURRENT REVERSING TRANSFORMER which are sold in the form of a power-saving device. Someone told me of a bulb which has almost no effect on the electric meter. Somewhere inside that bulb maybe a current reversing transformer.
Hence the meter uses electromagnetism (induction) it is also possible to interfere its movement by using magnets. The magnets of considerable sizes should be placed directly at the sides of the meter.…
Tesla would have to defy all expectations to achieve success on the Model 3, while avoiding all the potential pitfalls—not only for the 200-mile $35,000 Model 3, but a massive new battery factory, and the Model X that comes first.
Distance 200 miles (pure electric)
In January 2015, General Motors drew a line in the sand, proclaiming that it will be the first to offer an affordable 200-mile electric car. It will be based on a sleek small crossover concept, and due in late 2016 or early 2017.
The Model X is Tesla’s follow-up vehicle to the award-winning Model S sedan. The X shares about 60 percent of the content from the sedan—converting the sleek Maserati-looking five-passenger model into a stylish crossover utility vehicle.
Distance 107 miles (pure electric)
The Nissan LEAF is by far the most popular EV in the world. It is a well-equipped, all-electric hatchback that seats five adults and can travel up to 107 miles on a single charge. The LEAF is available to test-drive and purchase at Nissan dealerships throughout the United States.
