There are people recommending putting a coin on the WiFi router to make it work better. It’s stupid like a temple

The WiFi coverage problems They are a common evil in many homes and that causes all kinds of problems to arise. tips and tricks to improve itsome of them quite questionable. One of the viral tricks that has been circulating the most lately is the one that ensures that simply By placing a coin on top of the router we can amplify the signal of our WiFi. I wish it were that simple. The trick has been successful because it combines several factors: it is very easy to do, problems with WiFi are very common and it has a certain scientific basis. The logic is that, as the antennas are metal and the coin too, if we put it on top of the router we will make the signal increase. Let’s explain to you why it doesn’t make any sense. Debunking the myth of the coin and the router Placing a coin on the router has the same effect on the signal as leaving it next to it: none. For a metal to act as an antenna, it has to be connected to the circuit that emits the signal, but this is not the case. Between the coin and the circuit are other components, air and a plastic casing. Come on, it’s not going to have any effect. Placing metal near a router can even worsen the signal. If we surround a signal emitter such as the router with metal, we will achieve the well-known effect Faraday cagethat is, the signal is blocked. Obviously with a single coin we are not going to make WiFi worse, but this destroys the belief that a metal object on top of the router is going to amplify the signal. Photo by Pierre G on Unsplash As we said, the basis of the trick is that the antennas are made of metal, but there is a key issue and that is that not just any metal will do, it must be one who is a good driver. The metal that conducts electricity better It is silver, followed by copper, gold and aluminum. Euro coins are made of different materials depending on what currency it is. The 2 euro one combines a copper-nickel exterior with a nickel and brass interior; those of 50, 20 and 10 cents are made of Nordic gold (an alloy of copper, aluminum, zinc and tin) and those of 5, 2 or 1 cent are made of copper-coated steel. Even if the trick worked, none of these materials would be ideal for building an antenna. Tips that will improve your WiFi Most WiFi problems at home have their origin in one very specific thing: the router is incorrectly placed. The usual thing is that the installation comes through a wall and that we install the router right there, but it is a mistake. The more focused you are, the better. The router emits the signal in all directions, so if we put it at one end of the house we will be making the signal very good in that room and outside (on the other side of the wall), but it will be increasingly weaker as we move away from it. The best location for the router is to place it as centrally as possible within our house. Another issue to take into account is the obstacles. The walls, the closets full of clothes, the appliances… all of this will weaken the signal of our WiFi, so the fewer obstacles you have to cross, better. There is more tips that allow you to optimize the WiFi signal at homehow to keep your router updated or choose well what we connect to each bandbut if nothing works you can always turn to additional devices such as a WiFi PLC amplifier or what is by far the most effective: a WiFi Mesh system. I myself have suffered problems with WiFi at home due to a poorly placed router and The only thing that solved it was installing two additional mesh routers. I wish it had been as simple as putting a euro on top of the router.

For a reason as stupid as fun, someone put six wheels and two engines to a Renault 5 Turbo. And the result was great

Six -wheeled cars have always generated some fascination. From The famous Tyrrel P34 with which Jody Scheckter managed to win a Formula 1 career to the Mercedes G63 AMG 6×6 that became famous for their huge presence and their ability to overcome any obstacle in the desert. The story we bring today has a bit of the first and a lot of the second. The first because, we could think, a Renault 5 Turbo has much more to do with a “little” Tyrrel P34 (at least if we think of its 4.32 meters long for the 5.63 meters maximum that can measure a formula 1 current) that with a gigantic three -axis mercedes. But it also has the second because the original germ of this RENAULT 5 SIX TURBO He was born with the idea of ​​overcoming any obstacle that was presented to him along the way. Any obstacle that, for example, could be found in the Dakar. Yes, in the Dakar. A very crazy Dakar as advertising Those who approach the departure of the Paris-Dakar rally in 1980 had to find a picture as wonderful as amazing. As soon as you could meet four fools who intended to cross Africa with a Vespa as a modified Renault to shelter six wheels. Because that was, exactly, the great objective for which Cristian de Léotard He took the base of one of the most iconic sportsmen of those days to turn it into a three -axis car, six wheels, two engines and, of course, two gearboxes. Léotard was specialized in such modifications and, in fact, he had already experienced with a six -wheel cytroën C15. Did you think that the performance of the mythical van could not be improved? It would not be his only great work. In fact, the Mercedes Class G 6×6 has its origin in the workshop of this French coach. But its most striking, rare and iconic creation is, of course, the Renault 5 Turbo 6×6. Animated by his passion for mechanics and careers OffroadLéotard was gaining experience working within Tissier, a body company specialized in all types of extravagances, such as a Citroën Cx Camperized that seemed to keep a whole city within itself. Over the years, Léotard took his own way to found ADPL (Applicaton Defés Léotard) That, without a doubt, it seems a tribute to ADPT (Applicaton Deféés Tissier), the company in which it grew laborily and in which it sought all possible solutions to create a six -wheel range. That must have been the germ of his craziest project: take two Renault 5, paste them, get him to work with six wheels and face the Dakar sand. And he did it with great success if we attend to the figures. The engendro did not go too much as a mother (4.21 meters that are 10 centimeters more than a RENAULT 4 Current Electric) and only added 100 kg to the whole, being below the ton, as they explain in 12 cylinders. The image was so powerful that I couldn’t miss the opportunity. If I wanted to sell its creation to new customers, it had to show that the car was not only functional, it should also be resistant. The Dakar and its hardness were their best chance and tried to make the most of it. Although he had to retire due to mechanical problems, the rally had generated enough advertising to make a name in the market and, of course, the reference for all those crazy people who wanted to put two extra wheels to their Renault 5. Six wheels, two engines and two gearboxes One of those crazy people in charge of what would be one of Léotard’s most extravagant projects. Make a Renault 5 Turbo a six -wheel car fully functional and effective. To maintain the sports essence of the car and do it as extreme as the original, Léotard returned to “paste” two Renault 5 But this time he also took the opportunity to install a second engine on the front. The Renault 5 Turbo It is pushed by a propeller that sends all its force to the rear wheels. So that it was also effective from the front axle it was decided to install A second engine of Alpine origin 93 hp under the front hood to send the force to the front wheels. Click on the image to go to the original publication They explain in Motorpasion that Léotard described his invention as “a train with two locomotives.” To operate the two engines, the car had two boxes of independent changes and, therefore, with two levers in the front area that were synchronized. The car was, without a doubt, the result of the good work with its project for the Dakar. A car that, in the words of Sixmania (Where you can check more project photographs), it got a much more effective braking than that of the original vehicle, since the drum brakes had been replaced with brake discs on all its wheels. In addition, they assured that stability had improved and offered enormous performance in irregular land. This version Offroad Yes, it survived but the turbo version of this strange Renault 5 6×6 cannot say the same. At the beginning of the 2000s, The car suffered a fire that left it shattered almost entirely. The restoration was never achieved before Cristian de Léotard died in 2014 although in Secret Classics They ensure that a last collector did with what was left of the car to try to return it to life.
