"Not long ago, aiban.com got the first product for end consumers launched by Wuhan lingpu Technology: a creative self generating doorbell product linbell. As we all know, at present, doorbell products are not uncommon. It can be said that they have rotten the street and few people pay attention to them. However, this self generating doorbell product is still quite creative, 'self generating' is enough to attract everyone's attention, and netizens are also gushing about this novel wireless doorbell.
Here, we first have a detailed understanding of linbell, a self generating doorbell product, through the pen of Aiban engineers.
>>Linptech's sincere work - disassembly of self generating wireless doorbell linbell
Everyone has his own unique perspective. It doesn't matter right or wrong. You can be different from others' ideas, but don't deny others' ideas. Let's take a look at your thoughts:
@Janson_ Huang still compares it with the previous two products:
Unlike the riotboard on the tall front and the ATMEL sama5d3 xplained with low power consumption, the self generating wireless doorbell linbell has a small and fresh feeling. The appearance design is very exquisite, but I personally feel that the power supply design of the doorbell host needs to be improved (the space occupied by the doorbell host is a little large. It seems that if the row plug power supply is adopted, it may occupy multiple row sockets). The circuit design of the transmitter is the selling point of the doorbell, and the self powered design can really avoid the trouble of changing the battery. The receiver's three button design of mute, volume and music can basically meet the needs of users. Of course, it may be more fun to provide SD card and other ways for users to choose ringtones by themselves and improve the DIY capability of the whole machine. The price of 150RMB is slightly higher, but if the product reliability is really good, it is also a very good choice~~~
And @ zhaojunlin123 has its own unique views on product packaging:
When I first saw the packaging, I felt very simple.
When I saw the disassembly drawing, I was curious that when the transmitter was pressed, the so-called mechanical power generation felt very unique. Before ZigBee, mobile devices were involved. It was always difficult to understand the way of power supply. Either the battery life is short or the mobility is not strong. If the product can go on like this, it is a good development trend.
The second is the receiver. The first impression is that I'm curious about the voltage stabilizing circuit or module circuit, which is very exquisite. Unfortunately, I can't see the circuit. Maybe it's highly integrated, ha ha. The second is the wireless communication mode. I haven't contacted the 433M communication mode before. I don't know how the stability of the system is. In other words, it is applicability, such as anti disassembly and anti destruction.
If you can, I hope to learn the specific parameters and product introduction. If the applicability is strong enough, it is indeed a good trend. I dare not say it is a good product. In the industry of Internet of things for a period of time, I found that "Internet of things" is also slowly evolving. I don't know whether it is a trend or a concept. Big companies need to take the lead.
Finally, I hope this product can better promote the development of the industrial chain!!
Strong in the middle and strong in the hand @ treasuredog even gave his perfect score for this product:
First of all, let's comment on this article. The small editor of this article will give you some opinions. We must grasp the key points to write the characteristics of a product. What are the biggest characteristics of this product? From the first time I read through the article, I didn't understand... I realized it after re reading and thinking. It may also be that my personal understanding ability is limited. Physics is almost returned to the teacher~~
The title is very correct, "linbell disassembly of spontaneous electric wireless doorbell". I saw it, but the principle of self generation should be more popular. In particular, this self generation should be disassembled to make it clear at home. The article explains that "in fact, the mechanical operation of the coil can also be disassembled, but there is nothing to study deeply, In order to prevent the hard disassembly from damaging the key device, the author won't do this kind of thing. " Personally, this is the core part of this product. Dismantling it is really not painting the snake.
Let's talk about the biggest highlight of this product. The idea of self generating wireless is really applauded. Such small products can achieve non connected design and maximize compatibility with various decoration methods. Why not connect?
1. The transmitter generates power by itself in the form of coil, supplies power to the wireless module and transmits signals, which does not need a power line.
2. The wireless transmitting module sends a signal to the receiving end wirelessly, which does not require a signal line.
3. The doorbell is mainly directly inserted into the 220V mains power supply, which does not require specific wiring.
Therefore, this product can maximize the compatibility with various decoration methods. I think all my friends who have been renovated have experienced that after the decoration, they feel that some things have not been reserved, and they have to take the line. It's really humanized.
After the advantages are finished, the biggest disadvantage of this product is that "at present, this product is booked at the roll call time, and the price is about 150RMB. Friends who like it can support it.", It is estimated that the price is rarely accepted by the common people. Originally, the doorbell is a dispensable product for small family, because the knock on the door has attracted enough attention. Even if you choose the doorbell, you may consider the cost. Personally, I think it will be easier to promote it within 50RMB, and this kind of high-end doorbell will be more popular in high-end communities or villas, There is a very important technical index not proposed in this paper, that is, the longest transmission distance. You can think about it. In a large house, it is likely that the receiver is installed in the middle of a house structure, while in a large square meter or villa, the distance is likely to be 10 ~ 20m. Is this distance feasible?
Treasure dog, a friendship commentator on love board, comments here. In general, the creativity of this product is 10 points, the price is 5 points, and the disassembly article is 7 points. The prospect of the product is very promising under the premise of better cost control.
@Mengyun2801 was unwilling to be outdone and took out three similar products for detailed comparison:
There are many self generating products around us. I know three products with the same principle as this self generating doorbell. Let me introduce them one by one:
1. In the past few years, "hand pressed self generating flashlight" was often sold on the train or on the roadside, which generated electricity by cutting magnetic induction line. The flashlight adopted the principle of generator, used the swing arm to drive the gear, increased the speed through the large wheel belt and small wheel, and used the "inverse principle of motor" to generate electromotive force and store it in farad capacitor / battery. At that time, I removed the flashlight bought by my colleague and found that there were two parallel circuits in some cheating producers. When you toggle the switch to one side, the battery will light up the LED; When you dial to the other side, the LED will turn on and off only when you pinch it desperately with your hand. Because they did not join the charging circuit, for laymen, they just watched the excitement and were the owner of the pit~~~

2. In the course of "principle of invention" in school, the teacher told us an example. It was a Russian invention, a "rod throwing generator", a very simple gadget. It used enamelled wire to wrap a cylinder many times along the circumference, and then put a short magnetic rod slightly thinner than the cylinder into the cylinder, Seal both sides of the round tube. Then connect both ends of the enameled wire to the charging circuit board, fix the circuit board and the cylinder together, and you're done. When charging is required, the short magnetic rod inside can cut the magnetic induction line in the axial direction of the cylinder by shaking the cylinder, so as to achieve the purpose of power generation.
3. In recent years, charging treasure has become a disaster, large size, small size, large capacity and small capacity. At the same time, there are all kinds of self generating charging treasure. The most popular is solar charging treasure. This principle is relatively simple, and the application is relatively mature, and the conversion rate is not too high. But you've seen a handle type self generating power bank, which may be relatively rare. You can see it at a glance when you see the figure below. It's very good. The principle is the same. It can't be separated from the law of electromagnetic induction.

Handle type self generating charging treasure
In addition to the above, we have also launched portable wireless charging products in recent two years. Although it is not self generating, it is its emergence that promoted the birth of another self generating invention - generating power by using WiFi signal. This is a millennium news. Although we don't know what stage it is going to, it is undoubtedly a very good idea, And now almost all public places have popularized wireless networks, which virtually provides energy for some low-power products, which is low-carbon and environmental protection.
I don't think you are unfamiliar with the power generation insole, but so far, I've only heard of it, but I haven't seen the great God figure wear it out. Maybe I'll see it right away, because now wearable electronic products have entered a new generation, emerging in endlessly and dazzling. The power generation insole will also be very popular. After all, it is very real that you can get energy in a few steps. The following are two inventions I'm looking for. The first piezoelectric power generation shoe is well understood. It uses piezoelectric semiconductors to generate charge change through pressure change, so as to generate electromotive force, and then store electric energy in the battery. It looks very compact and powerful. The second invention, instep nanopower, absorbs energy from walking. According to American researchers, people are very powerful energy generators. They can produce about 1 kW of power when running, and there is no problem charging portable devices such as iPads and mobile phones in stores that can produce 20 watts when walking.

Power shoes:
Seize every trace of energy around us. Everything follows the law of conservation of energy. We can convert other energy into another energy. I didn't care much at first. After checking these materials, I found that it was really shocking. There are a lot of related self generating products, but it's better to do well and be practical~~~
To be honest, it's really hot to see this self generating doorbell on its official website. I really want to buy several sets, which are energy-saving, no wiring, convenient installation, and not close at the same time. For such a simple module, its performance parameters introduce that it is more than 30 meters outdoors and 10 meters indoors. It's very good. I'm surprised at its internal structure~~~
@Tryramtron expounds his different opinions on the evaluation articles from its most unique perspective
Hey, like many other netizens, I'm very interested in the title. After reading it, I know the author's typical title party!!!
To be honest, this evaluation cannot be compared with the previous two articles, just like the title, disassembly, just like the commodity evaluation post above Yitao, the specialty in non specialty and the non specialty in specialty. In fact, everyone is more concerned about self generation. Unfortunately, the author simply deals with it, but puts a lot of space on the receiver. In fact, the receiver uses ordinary technology, but the author makes great efforts to describe it. Although I wrote the article carefully, I can only blame the title of the article for being too "ulterior motives".
As for the quotation of products, I don't think it's a problem. We think the price is high, because we are relatively expert, and it's estimated that it won't be too expensive for the market. Besides, there are too many rich people now, and most of them don't understand the actual gold content. This product sells creativity.
It's not true how new the technology is. Seven or eight years ago, Holtek showed a remote control switch without power supply at the seminar to control the light on and off, supply power to the circuit through piezoelectric devices and send out wireless signals, but it was not ism communication at that time. Therefore, this product has no technological innovation, it can only be said to be application innovation. The real highlight is the display of low-power technology!!!
The wording is a little harsh, for reference only. Thank you for introducing this product!
@The advantages and disadvantages of this self generating wireless doorbell linbell are described in detail:
Advantages: the self generating mode adopted by the transmitter is very suitable, and the power consumption is very low; The industrial design of the overall system is quite good, leaving no impression of being a fake.
Disadvantages: the doorbell does generate electricity by itself, but the receiver has to be plugged into the socket. The electricity is still not saved. The power supply mode of the receiver still needs other modes. For example, RF energy harvest collects RF and microwave energy in the space. In this way, there is no need to use the electric doorbell, and the placement position can be optional, rather than relying on the socket. But this energy is used to drive the horn. I think it's enough.
