I don't know how many children's shoes know Brookstone, this is a professional retailer, providing a variety of more features, good quality, unique new design, and consumer products that are more difficult to find on the market. The previous Dong family is the United States. It has been jointly acquired by several giants in China, and now I have opened a few offline physical stores in China. It seems to be in Nanjing, Beijing and Shanghai, there are children's shoes to go shopping. .
Today, I mainly want to share with you a model fan to buy in Brookstone. This product is not very strange for the current engineers. I even said that many engineers have diy, this time I got it. The model fan name is MESSAGE FAN, and the literal understanding is similar to Chinese name. Of course, it is not tangled, but the price is still very expensive, and the model fan with a few dollars in Taobao from the appearance, still There is a lot of time.
Because Message Fan's seasonal property is obvious, many people think that they are not suitable in winter, so consider the thirteen, I decide that this article is not only playing, but will be disassembled to see what program is used. Ok, simply introduce a pass, officially start introducing Message Fan.
Exterior
Yizhi goods, product packaging boxes are English introductions and descriptions.
As the text is expressed, Message Fan is a "a cool way to send your message"
From the introduction of the box, this fan can be customized, that is, what you want to show what color font can be set by software, and it is different from the general single-chip development, this setting is not required. Professional background knowledge is suitable for most people.
Product accessories, fan, description page, CD (including electronic file usage document with software)
The fan quality looks good, touch the texture is also good, have a thick sense, there are no few dollars or more than a dozen dollars, the "light floating" and cheap sense.
The back of the Message Fan is the power switch. It should be noted that there is a very intimate design, the switch has two gears, which are just a fan and a fan of the characteristic effect.
Power supply is directly connected to the PC side by a normal USB interface, of course, if there is an adapter, it is possible.
use
Message Fan's software USB Data Download System can be found from the attached CD, no need to install, graphically, also equipped with the corresponding information, although the information is an English document, but it is not difficult.
After the software is open, you can see the basic menus and the operation, support Chinese and English, special characters, expressions, and other characters can achieve different display status, such as rotating clockwise / counterclockwise, flash, etc., can also support different colors adjust. The function is much stronger than the general modeling fan, but there is also a limitations, such as can't set the duration of the word.
The Usb Data Download System software is opened, and the logo in the right corner shows that the Message FAN is not connected to the computer.
When connected to the computer, the button of UPLOAD can also be operated.
I have found all the URLs under the Nonnet Group.
Press Preview to preview
Download via UPLOAD
In the download process, there is a red LED flashing. This red LED is separate. It is not the LED that shows the font (everyone will see the true capacity after disassembly), of course, there have been several download failures in the download process. The situation is unclear whether this USB download is unstable.
It is worth noting that the Message Fan fan switch during the download process is not open, and the switch can see the effect of the model fan after downloading the switch, as shown below.
Also took a small video, I want to see all the effects.
From the experience experience from Message Fan, a few points:
First, the essence of the fan is not lost, the wind is very strong, and the summer should be relieved;
Second, the characteristic effect is also more excellent, which can turn the characteristic effect, humanized design as a novelty. Summer delivery is good.
Dismantle
After the experience, you will then open it.
Messagefan is some standard cross-screws, and the dried screw should be easily removed.
Remove the base.
The fan protective cover is fixed by a fixing + a screw in the iron card.
Removing the fan can see the fan leaves and the LED module PCB that supports the characteristic function.
The bottom of the fan motor is a USB power switch and a data cable. It is worth noting that there is a magnetic ring protection on the data line to ensure the stability of data communication, and the details are good, but in the actual experience of the above, still discoverable data It is sometimes mistaken when downloading, it seems that the effect of the magnetic ring is not too big.
The composition between the fans is supplied or connected to the plug-in, and the power supply part is separated from the procurement, which is convenient to assemble mass production, and it is also convenient for after-sales maintenance positioning.
One of the two terminals on the motherboard is the power supply of the motor power, one is the power source for switching.
In addition, it can be seen that the USB data cable is directly welded to the motherboard, so that the dispersion is conducive to the wiring, unlike the USB signal line to an interface, then troublesome and notice.
Take the connection of the connector.
Remove the LED PCB module in front of the fan.
The LED is used with 11 RGB LEDs to achieve different color display by color combination. Speaking of this, this reminds me of this MESSAGEFAN's most difficult place or LED driver control, an example, each LED needs to be more than four states through software programming, respectively: Open, Off, Programming PWM Flashing Control Output, programmable each grayscale level, and supports PWM mixing output of four-channel overall brightness adjustment.
The Mark on the driver chip has been grinded, and it is a standard Chinese-style approach. I am afraid that I have been a cottage. I feel like a German chip.
In addition, I also saw that there is a TI sample application activity on the panel online. It seems that the success rate of the past is super high. I also apply for adoption, and the friends who need it can apply, the opportunity is rare. (Https://www.eeboard.com/bbs/thread-57690-1-1.html)
I saw the LED driver module and saw anything, a nut? Forgot this when processing is assembled?
No, it is obvious to fix it with glue. I didn't want to understand at the beginning. When I installed it back, I found that the position placed in this nut was not the opposite direction of the LED PCB module convex. When the LED module turned when the fan was rotated, if both ends The weight "does not wait, it will definitely make the fan body unstable, the purpose of doing this should be the balance of the fan operation, but see this design, it is a bit like this is not found, and then the actual amount of products will only discover, So I did this remedy, otherwise the design is really faceless.
From the perspective of the upper and lower charts, the signal line connecting the LED driver board (the enough wire in the figure) is directly flied from the motherboard? Design thinking has spanned, completely can't keep up, but it seems that there is no other way.
Generally, the metachard case is thrown, and the Message Fan is a fan plus a string of RGB LED control. In addition, from the motor motor of this fan, it is impossible to control the speed, turning, that is, a power-on electricity. That is, we only need to know its parameters, that is, the speed, the main design is still the control of the RGB LED, and the LED is lit at the same position by the speed of the same position, and fast rotation Then use the limit of our human eye, and the visual is temporarily, so I see the displayed text.
So the final design idea is basically shown in the figure below (the idea is slightly simple, forgive me, there is some signal connection and power devices), which is the switch directly connected to the motor, and the boost DC / DC and other power devices may be used. Connect to the motor power; another way is simultaneously connected to the motor and control the LED. If it is a simple LED, it may be directly controlled by the PWM signal on the single chip, and the RGB LED adds a quite number of quantities, it is necessary to specifically the LED driver IC.
summary
It is always said that Message Fan only looks like external workmanship and use is a very good product. You can use it to give gifts, and you will be happy, of course, don't send in winter unless you want to be single. Some "actual properties" in the dismantling process are indeed discovered that everyone will say that the dismantling is the same, and those "unconfident" manufacturers are very afraid that their products are dismantled, one of course It is afraid of being hosted (afraid to be seen by the cottage like the Mark's Mark on all the chips), and the other is that the design of "perfunctory" is exposed, spit, and Messag Fan is almost almost After the dismantling, I saw the internal design, it is not necessary to be exquisite, countless gifts, can only be an entertainment product for leisure.
