For a long time, I have always liked to write long articles, but there are some products that I really can't write. Therefore, we intend to open a new series - to study the short-term quick test, for a brief quick overview of small products, you are welcome to pay close attention.
â—‡ã€Product introduction】: In December 2014, Xiaomi released an aluminum alloy mouse pad with a metal sand blasting process on the surface, a CNC rimming process on the edges and a non-slip silicone pad on the bottom. The mouse pad is divided into large (price 59 yuan) and small (price 49 yuan) two, large size of 300 * 240mm, small size of 240 * 180mm, thickness are 3mm.
In fact, I have been longing for this product for a long time, but did not find a suitable opportunity to avoid the post, coincides with the previous few days in the millet official website to buy Bluetooth audio receiver, just put together a single.

MI millet aluminum alloy mouse pad trumpet / large aluminum alloy mouse pad, 49 yuan starting price, to know that peripheral manufacturers are rarely done so low. In terms of dimensions, the millet aluminum mats have a total size of 300 x 240mm large and 240 x 180mm small, with a thickness of 3mm. The manufacturing process is similar to similar products. Sandblasting, anodizing, high gloss and other processes ensure that the surface is flat, and the bottom integrates a whole piece of non-slip silicone to prevent the mat from slipping on the tabletop. Aluminium Mat's Value 10 Reviews 0 Genuine 6 Very Good 2 To Purchase View Details 
This time, I purchased a large millet aluminum alloy mouse pad. The first is for use, but it is easy to use as a shooting background.
â—‡ [Video Display]: Originally, I made several short videos and then I thought for a moment. I simply made a whole, roughly covering the entire original and helping valued friends realize a quick overview of the millet aluminum mouse pad.
â—‡ã€Front】:
Millet aluminum alloy mouse pad, the front of the anodized aluminum structure, the surface is smooth and smooth sandblasting process, stroked touch and Apple's Macbook series similar. The LOGO of Xiaomi is printed in the lower right corner of the front, but it is easy to wear, and a thin scratch can be seen after a few days.
â—‡ã€side】:
The side of the millet aluminum alloy mouse pad is the CNC rimming process. Similar to the practice of the millet 4 in the past, the individual feels good-looking is good-looking, but it really cuts his hands.
Put the mouse pad up and see from the side three parts of the millet aluminum alloy mouse pad, the left side of the non-slip rubber pad, the middle of the aluminum alloy, the right side of the CNC high-light chamfer.
â—‡ [bottom]:
The millet aluminum alloy mouse pad has a non-slip rubber on the bottom and a logo on the bottom, which is not easy to damage relative to the front.
The edge of the non-slip rubber mat and the edge of the aluminum alloy were not consistent, and I was slightly uncomfortable as an obsessive-compulsive disorder.
In the slidability test, the millet aluminum mouse pad lifted about 30 degrees, the mouse began to slide, indicating that the smoothness of the mouse pad is better.
In the actual experience, when using the millet aluminum alloy mouse pad, the smooth feeling caused by the sandblasted surface coating can be felt, resulting in a highly accurate and smooth experience for consumers. However, when it is used, it may also be accompanied by slight friction noise. However, after several days of use, no visible wear was observed when the mouse was stuck, indicating that the use of the mouse will not affect the life of the mouse.
â—‡ã€Advantage】:
1 millet aluminum alloy mouse pad products with solid materials, Yan value online: the use of anodized aluminum structure, with enhanced toughness and durability. The surface is smooth and smooth sandblasting process, the side of the CNC chamfering process to prevent the edge of the tilt, the back is non-slip rubber mat.
2 The practical experience of the millet aluminum alloy mouse pad is relatively smooth, and the cold mouse pad can cool the hand when used in the summer, and the touch is very comfortable.
â—‡ã€Insufficient】:
1 The front logo of the millet aluminum alloy mouse pad is easy to wear, the side slightly cuts hands, and the rubber pad on the back does not fit snugly.
2 During the actual use, the friction between the mouse and the millet aluminum alloy mouse pad will produce a slight noise. In the winter, the aluminum alloy mouse pad may be used and it may be cold.
â—‡ã€Assessment summary】:
From the manufacturing to the OEM industry chain layout, Xiaomi is also constantly seeking transformation. The millet aluminum alloy mouse pad, as a member of the grocery store, does not seem to have this feature compared to other products that are known to be cost-effective.
From the design and actual experience of the millet aluminum alloy mouse pad, personal feeling is still worthy of this price. As a powder rice home, I prefer the smoothness and coldness of this product. It also hopes that Xiaomi can launch more and better products on the road of department stores.

What is a miniature slip ring? Miniature slip rings are rotary electrical connectors that allow power and data to be transferred between a stationary and rotating structure. They are often used in medical, military, and aerospace applications where size and weight are critical factors.
A miniature slip ring typically consists of two parts: a stationary housing and a rotating contact assembly. The contact assembly contains the brushes that make electrical contact with the rotating structure, as well as the rings that conduct current or data.
The housing can be made from any number of materials, including metals, plastics, and composites. It is typically designed to be as small and lightweight as possible while still providing adequate strength and durability.
The contact assembly is made from precious metals such as gold or silver in order to provide good electrical conductivity.
Technology improves with the continuous development of precision machinery. The more sophisticated the equipment, the smaller the volume will be. And the space that can be accommodated for installing the slip ring is also very small. The key parts of some equipment are quite a district. Especially in the high-end military, aerospace and aviation fields. 360-degree rotation is required to transmit current and signals. And the installation space is greatly reduced. It is to make the equipment work more smoothly. Therefore, it is necessary to design the slip ring to be small and exquisite. Otherwise, it won't meet the needs of the installation.
At the same time, we have moved with the continuous development of science and technology. Various high-end precision instruments have been developed. It requires the slip ring to transmit the current amount of general power. Also often undertake the transmission of weak electrical signals and various weak signals. The transmission medium is wider, and the number of loops of the slip ring is increasing.
