Education field KY-MK98 mechanical keyboard case In 2022, KEYCEO received an ODM proposal from the American education sector in order to make the keyboard characters visible to teachers in class and invisible to students during testing. According to the buyer's request, KEYCEO launched the development of mechanical keyboards in the education field.   1. Demand Analysis With the development of modern education, computers have become an indispensable tool in education. For a teacher, the keyboard is a necessary work tool, and the mechanical keyboard is favored by more and more educators because of its stability, durability, and response speed. In addition, mechanical keyboards for education also need to have some unique design requirements, such as luminous characters to make class more convenient, and at the same time, it cannot affect the teacher's test or use in other scenarios.   2. Design idea: In this case, the designer needs to design a mechanical keyboard, the characters on the keycaps can glow in the dark environment, so that the teacher can use it in the classroom. At the same time, the characters on the keycaps should not be visible during the test, because it will affect the teacher's examination or test assignment. During the design process, designers follow the following requirements: 1. Appearance design: The overall design of the keyboard should be generous, simple, beautiful and durable. At the same time, designers need to consider the special lighting design and testing requirements of the keyboard. 2. Keyboard type: The target user of the keyboard required in this case is a teacher, so the designer will choose a 104-key mechanical keyboard. 3. Material selection: The designer chose to use strong ABS plastic and high-quality mechanical keyboard switches to make the keyboard shell and keycaps. 4. Keycap design: The designer uses a transparent keycap to make the characters shine. At the same time, the characters on the keycaps are realized through a forward openwork design similar to engraving, and the shape of the characters can be controlled by the openwork depth, font size, and line width. 5. Lighting design: The designer will use patch-type LED light-emitting diodes to emit light. The color of LED lights can be matched according to requirements. This method has stable light-emitting signals, high color saturation, and long life.     3. Process flow: 3.1. 3D modeling design: Designers use 3D modeling software to design the overall shape of the keyboard and the shape of the keycaps to ensure mutual fit and visual effects. The designer considers that the backlight circuit board can be used to control the LED to emit light, and the corresponding software code is written to control the light emission. 3.2. Mechanical manufacturing and processing: Designers use CNC machine tools to cut, bend, and rivet the keyboard shell to ensure that the overall structure of the keyboard is firm and beautiful. At the same time, select the special switch for mechanical keyboard for installation. 3.3. Production of openwork characters: Openwork characters need to be produced through precise CNC machine operations. Designers need to consider the precision and depth of each character in the openwork.   3.4. LED transmission: The designer fixes the LED light slot on the button with silica gel, and installs LED wiring to ensure that the LED light slot is focused and fixed. 3.5. Testing and debugging: Before final assembly, the designer needs to conduct testing and debugging to ensure the normal operation and quality of the keyboard.   4. Quality inspection After the production is completed, the designer will conduct quality inspection on each keyboard to ensure the stable performance and high reliability of the keyboard. The main test items will include keyboard repetition rate, key press force, luminous brightness, USB connection test, etc.   5. Production efficiency For the mechanical keyboard in this case, the production efficiency is relatively low. After the designer verified all the engineering prototypes, he started to invest in the mold manufacturing of batch and zero production. The engineering department will carry out the production of automatic production equipment and fixtures, which can not only ensure relatively high processing accuracy requirements, but also ensure the improvement of production efficiency. After all, for The education system needs to provide services with high quality and low price.       6. Market Prospects Mechanical keyboards for education are a new type of product with good development prospects in both users and the market. Teachers need to use mechanical keyboards in situations such as demonstrating courses, expressing their opinions, and evaluating students' homework, so as to give full play to their professional and human characteristics. Students need mechanical keyboards to simulate what teachers teach. Therefore, there is a wide market demand for mechanical keyboards for education, and at the same time there is more room for innovation worthy of development. KEYCEO welcomes more friends in the education field to work together to realize the future that has not yet been realized.    

Logitech's latest addition to its product lineup is the innovative Signature K855 wireless mechanical keyboard. Designed with limited office space in mind, thi...

Hello everyone, welcome back to the Break-less chat room. This time let's talk about mechanical keyboards. Recently, I have become obsessed with playing table games. It is a typical "people's food addiction". Under the premise that the personal collocation aesthetics and photography skills are both a bit clumsy, in line with the purpose of not being good enough and making up for the appearance, I want to find some people with good talents. Good things with high-value BUFF come to make up for my personal shortcomings. Therefore, this time the table is equipped with this Kezhi (KZZI) K75 three-mode mechanical keyboard with an online appearance and a very good user experience. This is the first time I have come into contact with Kezhi products, but just a few glances can make me remember it well. Although I have also played with a lot of mechanical keyboard products, it is good that Kezhi’s K75 still makes me feel very amazing when I disassemble it. Whether it is appearance or color matching, he is eye-catching enough, and it is easy to be remembered. On this point alone, Kozhi K75 has already made a good start in the experience of using it. In terms of color matching, the name of the Kozhi K75 color I chose this time is "Rhine", which is a slightly retro style. The combination of blue and orange is more agile and lively, and the overall look and feel is very harmonious. In terms of configuration, the K75 is almost full, the most popular Gasket structure at the moment; the dual type-c interface plus a USB HUB is located in the upper left corner of the keyboard; it also looks very natural with proper decoration, and 75% of the configuration is also The new players who are very popular recently have a tendency to exceed the traditional 87 arrangement; the three-mode switch is located in the upper right corner, which is ingeniously made into a scroll wheel, and the corresponding three modes are also marked, which is more convenient. , The K75 also has a small display that can display the power, which can also eliminate some power anxiety by visually displaying the power. In addition, the PC positioning board, Poron sandwich, PE shaft pad, and four-layer padding of the bottom sound-absorbing cotton, the TTC shaft seat is hot-swappable, and the capacity of the 3750mAh lithium battery is also sufficient. It can be said that the configuration can be pulled. Full and very conscientious. In terms of feel, this time I still chose the TTC gold powder switch which is my favorite. I don't need to repeat the word-of-mouth and feel of gold powder. It is worth mentioning that the soft, waxy and Q-bomb feel of gold powder is more prominent when it meets the Gasket structure, because there are four layers of filling and the addition of sound-absorbing cotton, the touch when hitting The bottom feeling will be slightly "boring", not so crisp and refreshing. However, the advantage is that the overall feel is relatively solid, stable and quieter, and the trouble of cavity sound no longer exists; repeated debugging and moderate lubrication also make the feel of the large keys very good, and the noise does not appear, and the experience is still very comfortable of. The "customization" trend that has blown up in recent years is not unpopular. Many friends, even those who don't have much contact with mechanical keyboards, come to chat with me and ask me to recommend some customized kits to them. Personally, I think that complete customization is a deep "fever" process, enough understanding and liking, as well as control of various performances, technologies and parameters, as well as personal special needs, etc., all combined can be used. To consider a customized type of product. In fact, I personally feel that lightly customized kits like Kezhi K75 are more cost-effective than fully customized products, and their individual elements and practicality are also similar to customized ones. Chemical products are comparable, saving a lot of budget to invest in some personalized keycaps for decoration and highlighting individuality may be a solution that is more suitable for most ordinary users. At least, the Kezhi K75 I chose is quite fragrant.

Dareu’s A+ series has always been its high-end product line, and it hopes to bring more fun and trendy products to players. The recently well-received A98 and A87 Pro are this series of products. Recently, the A87 Pro A new Twilight Gray color scheme has been brought, so follow me to see how the new color scheme performs. The packing box of Dareu A87 Pro is quite design. In addition to the data cable of type-c interface, there are also two-in-one puller, shaft puller, dust cover, and several supplementary color keycaps. As well as manuals, shaft promotion cards and so on. The A87 Pro adopts the standard 87 configuration, and the cloud gray color scheme adopts a three-color design. At the same time, the bright orange keycaps are used on the ESC and ENTER buttons to bring a good-looking color contrast. The indicator light part of the keyboard is also placed above the arrow keys. The switch of the keyboard is placed in the upper left corner of the same model of the A98 series, with the same wave switch structure. The evening cloud gray color scheme is a wired version, so this switch provides a quick two-level configuration of the light, and the light is turned off. The back design of the A87 Pro is also relatively simple. It provides a three-way outlet structure and a two-stage foot support, and the input angle that the foot support can provide is marked. The height design of the third gear can basically meet everyone's needs. The interface design of the type-c data cable is quite special, and the compatibility with the data cable is not high. Friends who want to replace the data cable may need to pay attention. After looking at the exterior part, do you feel that the A87 Pro is mediocre, so let's take a look at its inner part. The A87 Pro adopts a full-key hot-swappable design, supports tripod axes and pentagon axes, and is basically compatible with about 99% of the mechanical switches on the market. In addition to the built-in Dareu sky axis V3, it is also very simple to change the axis by yourself. At the same time, after removing the keycaps, you can see that the A87 Pro uses a slotted PC positioning plate, and at the same time, it is filled with thick sound-absorbing silicone between the PCB, which can effectively reduce the impact of the keyboard during typing. The vibration noise ensures the consistency of the feel. It can be seen through the PCB that a layer of purple silicone is filled under the PCB to reduce the cavity sound from the keyboard bottom case, and at the same time it can bring the HIFI sound effect that many friends like. On the side, you can also see the sound-absorbing silicone filled with the positioning plate just mentioned by the keyboard. This layer of silicone adopts the structural design of the fence interlayer, and the layer of silicone can be well fixed by the buckle of the upper and lower shells, so it brings a better use feeling. You can see that at the position of the big key, Dareu adopts the version of the sky axis with the blue axis. What is the difference between it and the ordinary sky axis? You may understand it when you see the above picture. Lanxin’s sky switch adopts 45gf pressure spring, which brings better feedback strength of the switch body compared to the original version of 40gf, so that the rebound performance of the large key position can be better, and the satellite switch is also fixed when it leaves the factory. After tuning, the consistency in use is very good, and the rebound force feedback is also very comfortable. The keycap part adopts two-color keycaps made of PBT material. The characters adopt a closed design, and the surface is also very delicate in matte texture. The overall typing oil resistance and comfort are very good. It is convenient to match the color scheme you like. For example, if you like plain, you can remove the contrast color supplement. Thanks to the standard 87 key positions, in addition to the supplied keycaps, it is also very convenient to replace the keycaps by yourself. The A87 Pro provides good RGB lighting effects. In the drive-free mode, you can switch between various lighting effects through the FN+F6~F11 keys. However, for the opaque PBT keycaps, the lighting may be more of an embellishment effect. If you like lighting effects, you may wish to replace some transparent keycaps or transparent keycaps for better performance. All keys are hot-swappable, the sky axis with a good feel, the fence-style Gasket structure, the "hand-feel sound package" with full configuration, and RGB lighting with various gameplays. Dareu has brought you a very good keyboard at the price of 400 yuan. One of the choices, if you want to experience a different feel, Dareu A87 Pro is worth experiencing.
