What is the laptop charger cylinder for?
All the small moving parts in your laptop, such as the hard drive, motherboard, video card and many others, rotate and vibrate with the ability to produce radio frequencies.
But at the end of the power cord of your laptop there is also an important detail: the cylinder, also known as “ferrite core”. It serves to prevent surges and strong variations in the electric current flowing through the cable. It should be borne in mind that every cable can potentially be an antenna, as it ends up absorbing and emitting radiation due to the passage of electricity. Therefore, the ferrite block will attenuate some of the interference by reducing electromagnetic noise.
Can we do without this cylinder in the cable?
Without the cylinder in the cable of your laptop and other electronic devices (such as your smartphone or even the USB cable of your camera), the radiation emitted by the cables could cause interference on your computer screen itself, for example. It can also be perceived as noise in the speakers, when you have your cell phone nearby.
The interesting thing is that there is no fancy technology inside that cylinder in the cable. In fact, it is the ferrite coating itself that plays an important role: it is in fact a kind of mediator, which aligns the radiation in different directions, to avoid all kinds of interference from surrounding equipment. In particular, this part will capture noise and transform it into heat. Therefore, the closer the cable cylinder is to the source, the more effective it will be.
The thing to understand is that the computer cable cylinder is a cheap and simple way to manage the proximity of different electronic devices running at the same time. It saves you from any possible degradation of your laptop’s performance.
Good to know When you cut through the plastic covering a ferrite core, you will find another metal cylinder inside. This part absorbs and releases any radiation while the current continues to flow inside.
Cold in the car? This button will allow you to heat up faster
When should air recirculation be used?
Activation of this button causes the closing of the air intake shutters in the ventilation ducts. This means that the ventilation system restricts the flow of air from outside the car. Keep in mind that the fan uses the air in the car and, depending on the selected temperature, can heat or cool the car. Thanks to this process, the air outside the vehicle does not mix with the air that circulates inside.
This closed loop is useful in a variety of environments, including when there’s a car emitting excessive smoke in front of you or when you’re stuck in a traffic jam. Most of the time, closing the circuit helps prevent bad odors from outside, thus preventing them from entering the interior of the car. Whether it’s the smell of sewage, manure scattered across fields, or smoke from a roadside fire.
In addition, air recycling is essential when temperatures drop. In winter, thanks to this function, you can heat the car faster and more efficiently to better cope with frosty mornings. However, it must be remembered that this circulation should not be used for too long.
In fact, it is necessary to switch to an open circuit to avoid fogging that spreads rapidly on the windows or the accumulation of drops of water. Not to mention, driving in recirculated air mode and a lack of fresh air can lead to a profusion of moisture exhaled by passengers. In addition to the fogged windows, the atmosphere in the passenger compartment will be stifling.
How to prevent car windows from fogging up?
Unfortunately, in winter there are more traffic accidents due to poor visibility due to fogged up vehicle windows. However, it is possible to limit the risks by practicing some of the following tips to prevent the spread of fogging. So you will enjoy a safer and more comfortable trip.
To remedy the problem of fogging on windows and windshields, you can get specialized products that will considerably reduce moisture condensation on car windows. The downside to these types of products is that they can leave streaks on the glass and can also dry out your skin over time. In this case, there is an amazing alternative: you can use shaving foam to remove this fog in the short term. It sounds weird, but it works! Just spread a little on a cloth and rub the entire tarnished area. Then use another dry cloth to remove any remaining foam.
Roll down the windows
This emergency option works when it is not too cold outside and especially when you can drive with the windows down for a few meters. The air inside is immediately renewed and the windows equalize their temperature with that of the outside, thus preventing them from fogging up.
Like shaving foam, it can also be alternated with a little shampoo. Spread it on a dry cloth and rub your windows carefully. Then, dry everything with a clean, dry cloth. Not only the fog will disappear quickly, but the car will also enjoy a pleasant fragrance.
How do I know if the batteries are still charged?
From kitchen scales to game controllers to clocks and remote controls, alkaline and saline batteries have invaded our homes. Our boxes and drawer bottoms are full of batteries that we don’t know if they’re still good. Stop! Here are some tips to make them profitable and save energy.
How to tell if a battery is dead
The musical book that no longer wants to sing, the electric chain that no longer wants to turn on, the remote control car that no longer wants to move and that’s it, we change the batteries and get rid of the old ones. However, studies show that half of the batteries that are thrown away are still charged. Here’s how to test your batteries without any hardware in seconds to see if they still have power.
- Take your stack in your hand, hold it vertically
- Place it upright on a hard surface such as a table.
- Raise it 1 or 2 cm and let it fall vertically.
- If your stack falls vertically, it still contains some charge, if it falls flat, it’s empty.
And why will you tell us? Simply because a charged alkaline battery contains manganese dioxide, which is a heavy, pasty substance that will somehow weigh down the battery. As this dioxide is used, it transforms into much lighter manganese oxide.
Afterwards, if you want to test your batteries in a more precise and scientific way, you can always equip yourself with a multimeter. It measures the voltage of all types of batteries and allows you to classify your used and still usable batteries.
5 tips to make batteries last longer
We often tend to prefer disposable batteries to rechargeable batteries because they are less expensive, can be used right away, and discharge much less quickly. A French household has an average of 100 batteries. However, an ADEME study shows that they have 30 times more impact on ecology. So if we can’t do without them, let’s at least try to save them for the sake of the planet and our wallet.
Here are some tips and tricks to make your batteries last longer:
1-Keep your batteries well: To preserve the qualities of your batteries, it is necessary to store them in a dry place at a moderate temperature between 20 and 25°C. So they work longer.
2-Limit the time of use : try not to use a battery without interruption for too long a period of time at the risk of discharging it more quickly.
3- Remove batteries from devices. : When a device is not working, make sure to turn it off completely or even remove the batteries, because sometimes there is a little power consumption even when not in use. Also, batteries that are left in a device for too long can sometimes leak and leak.
4- Change all the batteries at once : In a device that requires several batteries to work, it is better to change the whole series at the same time. It’s a matter of balance. In this way, all batteries will be used evenly and will last longer.
5-Reuse discharged batteries : It is not because a battery does not work in a toy that it can no longer be used. In fact, there are devices that consume more energy than others. Instead of throwing them away, reuse them in remote controls and wall clocks, for example, since they use much less energy.
Caveat : Never crush, puncture or otherwise damage the battery. Do not throw into fire under risk of explosion. Used batteries must not be disposed of as they contain toxic substances. They must be deposited at dedicated collection points, then they can be processed and recycled.
All you have to do is take these simple actions to optimize the life of your batteries and why not consider investing in rechargeable batteries that are ultimately much cheaper and more ecological.
