After the rice cooker broke down Don't sell it as waste. In fact, there is a valuable treasure in it. It's this little piece of aluminum He also has two hidden functions Even the junkers. He doesn't even know These two functions are particularly practical. You see, this is a 220-volt, 40-watt This is a thermal insulation sheet It has a constant temperature function In the middle of life ah Very practical In fact, it has two hidden functions for everyone to share. First of all, after we remove this security film Then we'll connect him to two power lines. These are the two lines above. On top of one, connect a line to it. After receiving it like this Then I 'd like to share with you its first wonderful use. Both the first and the second are particularly practical You see, that's it. After you pick him up Then, let's use an electrical glue to wrap it around him first. Make an insulation This insulation must be done After you do it Then, I 'd like to share with you his first wonderful use. When we use it First of all, let's give him this thermal insulation. Find something to fix first. Not looking for an iron thing Then there is a fixing screw position on this one. We screwed it into a screw. Make a bracket to fix it first. His first function is that it can be repaired quickly. These broken led lights at home What happens when these lights break down? We dismantle the lamp beads There is no way to dismantle it with an electric soldering iron. In this way, we can use it instead of the soldering station. Because this security film has a constant temperature function. So say, when removing the lamp beads No matter how to tear down How long it will not burn the lamp beads on it Gently clip with tweezers This little lamp bead was taken down. You see the speed is very fast Both disassembly and assembly are very practical. Look, let's take down these lamp beads. Can also be used twice If you remove it with an electric soldering iron This lamp bead is broken. When we fix the lights When you look up and install the lamp beads Just align the position and put it up. This is its first function. Then let's look at its second function. Usually when we connect the water pipe Especially this iron pipe When connecting this plastic pipe So how do you get the two of them together? Let's see. We put it on top of this insulation. Give it a warm first This security film has the function of constant temperature. After the heat is added This pipe is not burnt at all. Then we can pick it up quickly. You can see that the plastic pipe is very soft. So you can put it in At the end of the day, we'll tie a wire to it. You can connect this hose to it. How about it? This aluminum sheet has two functions very good With what Thank you all for watching Hello friends Today's video will share a beer with you. A wonderful use of bottle caps in our lives First of all, the first step is to take out a bottle cap. Then, let's smash it for him first. After the bombing Let's take a look at this level Let's take a look around the rim of the cap. Does it look like a jagged shape? Be sure to remember the edge of this piece Don't smash it too peacefully. If the smash is too peaceful Later, when we use it, it will not be very useful. Then we'll pad something Let's put this bottle cap on it. Use a hand drill to drill him Be sure to find this position in the middle. Yo, I'll give you milk I'm all Done When operating Everyone must pay attention to safety Good to take it down And then what, we're on top of this wear a screw Here it is. Screw a screw cap. And then we have to screw it firmly. Tighten Clip a pair of pliers on this side Twist again with a screwdriver Be sure to twist firm OK, let's take a look at what it looks like after the screwing. Take a look Is it like a mini cut piece Then we put it on a hand drill to try it out. See if this tool works well or not. Let's cut a PVC pipe first and try it out. Let's take a look It's easy to cut it open. And then you can use it to cut a piece of wood. Let's try OK, let's take a look at this effect. The effect is still very good, isn't it So we are in the middle of life Whether it's cutting wood or PVC pipe Good-by, when we're working. What if the space is relatively narrow We can ah with a beer bottle cap In this way, a small cutting mat can solve the problem. This method is very practical Thanks for watching today's video. We'll see you next time Hello, friends. Hello I am Lao Wang Today, a beautiful induction cooker came to the store. He said it couldn't be heated properly. Let's take a look together This is the one Then we electrify it Turn it on and look at it. Turn on the machine and boil water. We add the sound of clicking inside It is can reduce pot It just can't be heated Let's take it apart and check it out. After disassembling We first have to look at it from the outside There's no obvious burn-out of the original And then we look at the back of this Also did not find any open welding virtual welding or burned out the original ah Like the beauty of the induction cooker does not heat It also does not report an error code. It's just that this buzzer is dripping Like this situation We first have to check these big color blind resistors on the motherboard Look, both of these are 820k And then we'll check the back See if there is a particularly large patch resistor. if there is one We also need to check I don't see any on the back. Just these two in front. Then there is another one. This one generally does not affect The main thing is that we need to check Two of these high-powered resistors here. The bad is more Let's use a light meter to measure Look at their organization. See if there are any problems. The general is to open the way or the organization becomes larger. We have to disconnect an angle from it when we measure it. If you don't keep the angle open Measuring it is not so accurate. We set it to two megabytes with a watch. is 800 838 is no problem He is also within its scope. Then we measure the resistance again. We still give it the same thing to disconnect one pin at a time. And then we measure This has opened the way There is no organization have a look I found a more accurate than it. Resistance of 820k Let's put this color resistor on him. We'll try again after we put it on Start water boiling It's already heated Friends. Thank you all for watching See you next time. After the electric fan at home broke down Never throw it away It only costs ten dollars to buy a universal motherboard. Use a screwdriver to connect the wire and you can use it. Super simple Can be installed without electric soldering iron Repair an electric fan today The bad originals on it are too much No value repair And then? I 'd like to share with you an installation method of this universal motherboard. In fact, the operation is very simple This universal motherboard also comes with a remote control. It is very convenient to use Now let me share with you how to install it. First of all, let's take a look at this power cord. First put the power cord We cut it first Step down Then give him the thread first. Then, let's take a look at the incoming line of this universal version. There are three on this side One is the public line a line of fire a zero line We connect this power line, this red line to the fire line. In fact, these two lines are casually connected to the fire line. The zero line is indistinguishable. Just connect it directly Let's connect these two lines to it. Then connect another power cord OK, this power cord is connected Then look at this old board again. This one is marked on it. 123 these three gears This blue one is first gear Let's cut this one out first. After cutting it out, we'll screw this on to the new version. First, dial the line for it. It's good to pull out the thread ends. Let's take a look at this board This also has a. This is a gear We'll connect it to the first gear. Then, let's look at this white one. The white one is marked as two here. This is the second gear We cut it off Or do you want to pull out the thread first? The same installed in the corresponding position On top of this new board have a look This is also a place to mark this two. Screw it to this Actually very simple Just install these lines corresponding to that one. The red one is third gear. cut it off After removing the thread ends, connect it to the new third gear. And then we look at this black line. Mark an s above We cut it off This is the line of a moving head motor. We attach it to this bobblehead table. Twist all this thread to it And then? Let's take a look at this side. A common line is not connected. Look again, these three lines are connected to this position. We cut it out the same way. In this line, we are receiving the new version. The new version of this Above the public line That's it. That's it. And then? We need to fix this board. Just set it at this point Before loading the shell Let's charge it first to test it. See if it can be used normally. Good can hear a drop of sound And then we turn on this switch This fan does not turn Then try shaking your head Yes, you can shake your head normally. After inspection Found that his motor is also broken I feel like I should go buy lottery tickets I won the lottery today. This is a new motor. Let's test it Let's see if we can turn normally. You can turn, right? Then the wind speed can also be adjusted Shutdown is no problem Thanks for watching. We'll see you next time Today we refit an electric fan for our customers. He said that his electric fan was in first gear. It's the slowest gear. He said the wind speed was still a little fast. He asked if I could change it for him. Let the wind speed a little slower. The wind is a little softer. But he also has a request It is when the fastest gear is in third gear. He thinks this speed is still the same as before. Let the wind speed is very big Speed is very fast He thought of a way to solve his problem. It is to convert these three gears into 16 gears. Divided into slow third gear and fast third gear After the modified car is modified, it can meet his requirements. First of all, let's take the electric fan apart. Then the original required for modification is also very simple. Just need a capacitor like this If there is no such capacitor In fact, capacitors like this can also be used. They're both the same can be used Then you need a boat switch like this. If there is no such boat switch Only one capacitor is needed Can also be used to reduce the speed of the motor Let me share with you first. The combination of these two retrofit methods Then, I 'd like to share it with you again. A Modification Method of Separate Capacitor First find a suitable place inside the electric fan Put this switch on it, uh... First, make a hole. My method of opening the hole is very simple Just use a scrapped electric soldering iron tip to probe a hole in it. This switch I selected a two gear Three Pins Put this on it. And then what, we give it this capacitor Soldered to the corner and triangle of this switch After welding Let's look for the power cord on this fan. In fact, these two lines are the same We cut a line Just cut off the red one. Both are the same We actually cut it After cutting, we'll give it both ends first. This article is the same Fit line head After the dial We welded these two ends to the switch separately. Uh... These two are actually not positive or negative Just weld it up We solder this on top of this capacitor. In addition, we welded this power cord to the middle of the switch. on this stereo In this way, it has been modified. Look, it's very simple, isn't it Let's give it to me and tell everyone Let's take a look at this power cord first. It goes in from here, after it goes in. When we turn this switch to slow He is the conduction of these two pins And then he went in and then go here through a capacitor Then go back to the elevator After the capacitor it lowers its voltage Then the motor will turn slower. And then when we turn this switch upscale It is the conduction of the front two angles. Let's take a look at this circuit. After entering, he came out directly. It is with the original speedDegree is the same The voltage is the same If you don't have to do the switch In fact, turn off a capacitor Only a single capacitor can also be used to change the speed of the motor But he can only change the speed of one gear. We put this capacitor 70, uh If the case of a gear We cut this blue line through the middle. Then string that capacitor This gear can be turned more slowly. When choosing this capacitor The greater the capacity of the capacitor The less it drops. The smaller the capacitance The more it drops It is the smaller the capacity of the capacitor. The slower the speed of the motor, the slower it will be The one I chose was sent by 3 3 digits. Now let's put it up and test it. Okay. I wrote a label here Let's take a look This is slow third gear Then this is fast third gear Let's turn the switch to slow third gear first. Here to test it First open a gear And then we look at this fan The fan may not be able to see its speed. Everyone can listen to this wind you can tell the speed Now it's up and running Listen to the wind speed. Then we can compare Put this back in fast gear. Then test it Listen to this wind speed has not changed It's obviously fast, isn't it? much faster Then we'll move to the slow Then these files can be used The speed is slower than before. Want to reach the previous speed We'll just put this in fast gear. The wind speed in the world is very high, isn't it? This method is very good I'm going to apply for a patent next. To mass production of this electric fan Many novice friends in the use of electric soldering iron welding wire Or when soldering some electronic components It's not easy to weld it. Even after welding it up is also very weak It's easy to fall off What about today's video? Let me share it with you Some of my experiences with electric soldering irons including some practical tips First of all, let's take a look at this commonly used electric soldering iron. Generally divided into two kinds One is this kind of external heat There is another kind, which is this kind of internal heat type. I like this kind of internal heat Because this kind of internal heating electric soldering iron It's small, um... Easy to operate Like this outsider Look at this head a little bigger A little more stupid Look at that. Especially during operation. Take a look at this handle, this kind of external heating Take a look, right? Because this hand is grasping this part Far from the soldering iron head it is OK to weld some big circles If you weld some small circles It's not easy to operate, is it? Because the distance is too far It's not as short as this inner page, is it? The operation is more accurate when welding small components. Novice friends in the use of electric iron Generally divided into two situations One kind of situation is this electric soldering iron tip. No matter how to get this department It never gets away. There is also a kind of situation, that is, after the refinement is opened If you want to solder that wire or some electronic components What about this pin? It just doesn't stick to tin What about these two situations? Let's share this first situation. It is usually caused by oxidation on this soldering iron tip. What about this situation after oxidation We need a soldering iron tip. Let's take care of it first. Is to find a piece of this old board first Then dip it in rosin and solder it on. A few more rubs on this In fact, after a few more frictions You can grind off the oxide layer on the tip of the soldering iron. After grinding off, it can be better sticky and thin. Alas, it can be used up after grinding. See no. After the heart is pierced Then look again Let's weld a wire to try it out. What about when the wires were first soldered? What about this wire? First, pull out a wire skin. Then cut off a piece of it. don't need to be too long Just leave a part. Just leave so much Before Han? First of all, give it first. Let's start with some rosin on this line. Or spot welding oil Uh, then, uh, put some solder on it OK, have a look That's it. First, spot solder And then it's the same on the board that needs to be welded. Before welding, give him some rosin. At this time, when we weld up again It will be very easy have a look In this way, I will go up directly at once. See no. The sweat is still very full And then it's sticky and very firm. Rigidity If Let's take a look at this wire first. First skin him. Let's talk about it again. Good. Let's take a look at the skin first. There are still some situations Wires or some electronic components It doesn't stick to the top. What about a situation like this Generally, it is caused by the oxidation of the wire above. What about a situation like this We need to get rid of this oxide layer. Get a piece of iron or a blade to scrape it. After scraping all its oxide layer Then what, then the second step Then it is to dip some rosin and solder on it. So it's easy to get on See no. Go up directly to solder In this way, it is very easy to weld. Okay, now, let me show you how to weld wires again. First of all, it's still the same. First, give it some rosin on the wire. Spot solder on When choosing solder If you weld some small circles Try to choose this solder wire Make it a little thinner In the case of welding large raw materials The meaning that can be used rough is I'm using Hannes is 0.5 very fine Because I often weld some small components Both ends are soldered to it. And then when we weld it up again? First of all, spot solder on the electric soldering iron head Then start welding to the top OK, have a look Now, it is directly welded up at once, right This welding is still very firm These Internet TV boxes we use at home There are also two very useful functions The first function is that it can support mobile phone wireless screen projection No matter the photos on the phone Video songs can be used wirelessly on the TV The second function is even more powerful. In fact, it is very practical for all of us. Now let's share it with you first. This function of mobile phone wireless screen projection The wireless connection is via wifi, uh Network connection on top of the TV box After the connection No matter what is on the phone Can be directly cast on the TV to watch Whether it's still learning or playing for your own entertainment. are all very good The first thing is to open the electric box first. Then turn on the TV Then, uh, first take out your cell phone, uh Slide up at the bottom of the phone. Find this screen here. The screen projection software on the mobile phone This is it. I have a screen mirror here. Just open it. And then? You can scan directly into this LAN here This is my cat magic box Because my Internet TV box is Tmall Magic Box So, that's what I found. And then what? Click to connect it Now connecting Well, after the connection is over. The TV set can directly show the picture of the mobile phone. Let's see it's already out, right Is the picture created exactly the same, right Then, you can play music. Then the video, including learning things, can be played directly. First of all, let's turn on a tremolo and have a look. No problem, right? It's all possible Then you can play some sound We wait for a taxi No problem, right? It can also be used as a horizontal full screen. First of all, change a boss I'll have a sausage wrapped in scallions. Then let's look at the full screen After clicking directly, it can be played in full screen. But Sophie wasn't afraid Because she's very inferior to her appearance. The screen is actually that simple. At present, many network charges have their own wireless screen projection function. What if the second box of your network does not have this function In fact, it is also possible to give this TV box Just install a wireless screen projection software It doesn't matter if the mobile phone doesn't have a wireless screen projection function. You can also install it according to the software of wireless screen projection. After the good ah The two of them can realize wireless screen projection. The method of wireless screen projection is so simple. Then, I 'd like to share the second one with you. It's a nice function. is that we can look at, uh Each of these is this kind of network TV box In fact, there is a usb socket like this at the back of it. Let's take a closer look Just this socket What about this socket? It can give this Internet TV box You can plug it in a USB flash drive Upgrade it to use Or you can plug in a USB flash drive to play the video on the USB flash drive. or songs or photos to use But these are not important It has a very important function This function is to let us turn the charging line of the mobile phone Plug it in Then we can have a look. He can charge his cell phone. While charging? Then let's have a look Then he can also With the phone's wired And then put it on the TV. In this way, you can charge the mobile phone while throwing the screen. Then, if some digital products in the home are out of electricity Or the charging head of the mobile phone is broken What if there is no situation? Yes. Just plug it in the back and charge it. This method is very practical Everyone will definitely be able to use good videos in the future. Thanks for watching. We'll see you next time The TV set at home is broken and will not be turned on. In this case, don't worry about spending money on repairs. Today, I'll teach you a trick, uh In fact, you can fix it with a USB flash drive. What about TV sets? If there are two situations We can all use U disk to solve The first situation is after the TV is turned on Just like the current situation Set on this boot screen And then, no matter how long you wait, you can't get into the TV. There's another one in the system. What about another situation? That is, after the TV is turned on It's just that this picture keeps appearing. After waiting for a long time It just turned off What about a situation like this See if this is turned off Now this kind of situation generally means that it is a TV set. Its system is broken We just need to use a USB flash drive to give it You can fix it by brushing it off. Before the camera. First we find this TV It's a brush pack It's an ace We open this ace Then, find the same model below. We must find the right model You can't just download one. If the download is wrong, it will not be brushed later. We found the same model Then download it. After downloading? We plug the USB flash drive into the back of the computer My USB flash drive is a 16g When choosing this USB flash drive, you cannot choose too large one. If the capacity is too large The TV may not recognize it. Therefore, there is no way to brush the machine. Choose the best of this capacity It's four g's or eight g's. Maximum cannot exceed 16g What about the format of U disk? Select f a t32 If you use another format Maybe the TV can't identify it either. The success rate of brush machine one is relatively small It seems that this is f a t32 The best before the machine Is to format the U disk for him And then when formatting Choose its format is this kind of ah f a t32 Just choose the default one Then click Start After formatting like this The chance of brushing the machine is a little more likely to be successful. OK after formatting Then we'll download what we find. These three files give it directly Just send it to the U disk This file is still relatively large. More than 400 megabytes Let's take a look at these three documents. This is mainly his brush bag. This is more than 400 trillion Then the other two are its guide These two files are relatively small The USB flash drive was made as simple as that. Then we will start to brush the machine Before brushing the machine First, unplug the power cord of the power supply machine. Then, plug the hard disk into the usb socket of the TV. Make sure you stick it under there. Then, let's press the power button on the TV with one hand. Hold down and don't move. Then the other hand electrified it. Okay, now, let's take a look at the TV. What's the change in the picture? But now, this is the power-on button that has to be held down all the time. Don't loose Now showing upgrading Don't let go UntilLet go after the progress bar comes out. This progress bar goes after 100 percent. Then the TV will restart automatically. The TV will be repaired after the restart.
