Since the red axis of a pirate ship k70 entered the pit, it soon cleared up the green axis, the tea axis and the black axis. But to look at Aunt Zhang's mechanical keyboard is a little bit more, I feel that I can't write new ideas, I'm too lazy to diy, so I've been too lazy to write a single sheet. However, on the road to buy and buy, I read many articles, coupled with my own experience, and I have a certain understanding. I believe that I can write an article to guide the students who are using an ordinary keyboard to enter the pit properly.
Pit reasons (why do you need a mechanical keyboard):What's the reason for buying, buying and buying? If you must need a reason, it is: In order to experience the feeling of fingertips. If you have friends around you, you can quickly borrow and try it out. I believe you will be addicted. The mechanical keyboard is definitely a very cost-effective object. The reason why I say cost-effective is that relatively little money is spent, but when you work in front of a computer, you always feel inadvertently refreshed. It is a must-have good product for modern people's work and life, and effectively improves the work happiness index. If you want me to answer the question “What are the little things that make you look late and can really improve your life happiness index?†then the mechanical keyboard must be on the list. It will also include hifi headphones/Bluetooth headsets and Kyocera ceramic knives. Panasonic Mini Rice Cooker, PS4 Game Console, Braun Electric Kettle, etc.
Pit Instructions (Preliminary Selection):If the budget is not very tight and it is too lazy to be tossed, it is recommended to directly enter the original shaft (cherry shaft), and the quality and feel are guaranteed. However, in fact, domestic brands independently developed the shaft feel is not necessarily bad, and personally think that the current price of the original shaft mechanical keyboard is still somewhat high, after all, this thing is not a keyboard black technology, so that the material prices are still thousands of times or Very dark. The relative price of domestically-made mechanical keyboards is relatively close to the people, and there are deviations in their feel but not necessarily bad. After all, everyone tastes different. The main need to pay attention to the axis type and the initial pressure of the button, trigger pressure, because the touch of a brand's so-called green axis is too tiring, you need a strong King Kong, this keyboard is to torture yourself.
If it is determined to purchase the original axis, personally think that the next thing to consider is only the layout and value. Personally feel that if the general office, then surely use 100% standard keyboard is generally 104 keys, if you rarely use the numeric keyboard can be considered 87 keys (as shown above), if home entertainment basic game can only consider 60% of the keyboard. Of course, the best use is definitely 100% keyboard, 87 keys castrate the numeric keypad area, although the main keyboard area can still enter numbers, but if it is office to do the table and the like often have to hit numbers, or the digital area to be a lot easier, even if It is usually when the user enters an account number or a mobile phone number, it is estimated that they also use the numeric keypad area.
The 60% keyboard is another kind of extreme. The numeric area, cursor keys (direction keys), and function areas are all castrated. Only the typing area is left, and other functions require the use of work key and specific keys (key combination). achieve. Benefits As the above figure shows, the wrist basically does not need to move, and the input efficiency is higher when you are familiar with it. And the keyboard has become a lot smaller, in addition to beautiful appearance, the right side of the vacant large area to operate the mouse to more smoothly. The disadvantage is that there are no arrow keys in addition to the numeric keypad. When the text is entered, the cursor position is often fine-tuned. There is no arrow key or the combination key is inconvenient. Of course there are some variants of standard keyboards, such as keyboards that incorporate arrow keys in the numeric area, or more custom keys.
However, individuals do not recommend these variants because changing the layout of an ordinary keyboard has a difference in learning costs from ordinary keyboards. Second, some keys need to be used in conjunction with function keys. However, compared to these variant keyboards, the most not recommended is to add custom keys to the edge of the commonly used function keys (edge ​​of the keyboard), such as the pirate ship k95
So before there was a k95 rgb a thousand or so special offer I did not enter, one is the average player to so many custom keys simply useless (so many key programming can not remember), and secondly, the custom key on the esc, The ctrl and other common keys are easily misused on the edge. In the end, we still chose the practical k70, which is quite satisfactory.
In addition, there are friends around to buy the black widow green shaft and then actually gave it away for a few days, mainly because of the pit father's custom key position, and later helped him to get the ikbc c104 tea shaft now used very happy.
The reason why Ikbc is recommended to others is that it is a good reputation for price and secondly, it is a real experience of oneself. After buying the pirate ship k70 as the first mechanical keyboard, he also bought two ikbc, a green axis of a tea shaft, the experience is quite good, and the price of the two added together is similar to the pirate ship. .
Personal feeling male home entertainment Corsair with such a high value of backlighting is good, ordinary office, then ikbc is enough, white face value is also quite high, you can also buy a variety of keycaps with the specific reference to the station sun single.
The article on the axis is still a lot of online, and it is more detailed. Personal capacity is limited. Here I only talk about my feelings about mainstream axis combined with chart data. First, the red axis and the black axis are a kind of axis body, because the forces that are exerted when the red axis and the black axis are pressed are all linearly changed, that is, the greater the force that is required to push down and down. The difference is that the resistance of the black shaft will be greater, and it will be more laborious to press it (of course, the rebound will be faster, and the response will be faster when continuously hitting).
The tea axis and the green axis are a type of axis body. After pressing down to a certain degree, the starting organ will generate a slight boost, so that the keys will have a sense of passage. In particular, the blue axis will emit a crisp sound when hit. However, the green axis is somewhat different from the other three axes. That is, the key path of the blue axis is relatively long, and the distance needed to be pressed before the trigger button is longer, which can also be compared from the gif.
The above figure shows the keystroke-pressure curves of the four axes that I have made, which are relatively sketchy, but I also understand the differences between the four axes. The red axis and the black axis are basically linear in the actual measurement, while the green axis and the tea axis have a curve change process, so there will be a sense of passage. In addition, the square data point in the figure is the trigger point of the key, that is, the keystroke to this trigger input. From here, it can also be seen that the key axis of the blue axis is longer. Here again summarizes the point of attention of the selection of the shaft (this paragraph is basically written for the value of the friends who have not touched the mechanical keyboard, because the general contact with the mechanical keyboard of these four shafts are all bought it): overall In terms of clarity, the blue axis is crisp, the red axis is smooth, the black axis is fast, and the tea axis is delicate. The first person who touches the mechanical keyboard will surely like the green axis. The sense of passage is very strong. This is what the average person thinks of the mechanical keyboard. There are also many people who have been recommended to use the red axis from the beginning, the sound is relatively small, the response is faster than the green axis, and the home game is very good. The black axis is less likely to be purchased, there is no sense of passage for the first time, and secondly, the key resistance is greater. Personally think that if it is to be in one step, then the tea axis is the most suitable, because the noise of the blue axis affects others and the keystrokes are long and they will feel tired. Although the red axis is extremely smooth, it is easy to mistakenly touch because there is no paragraph sense and the short keystroke trigger pressure is small. The black shaft is not generally not selected for heavy flavors. Compared with the tea axis, it is a perfect choice. There are sounds in the paragraph but not large. The trigger pressure is small but it does not touch. Some people say that the middle axis of the tea axis has no personality, like a film keyboard, and personally thinks that it is purely nonsense. The feel of the tea shaft and the feel of the thin film keyboard are still very different. The subtlety and blurring are completely two concepts. The feeling of the tea shaft is not only It's addictive, and it won't be greasy for long periods of use. So the name of the tea shaft is also very well and it is a shaft that is worth savoring.
================================================== =================
Evaluation section 1: AppearanceSay so much, still return to ikbc this mini-keyboard, out of the box
Ikbc packaging has always been very simple, I like this one, it is environmental protection, and secondly, to spend money on the edge, to provide users with better products is the king.
Surprisingly, ikbc also provided two very solid data lines for workmanship. One is a type-c switch to a normal type-a, and the other two are type-c. It's really kind. Some people say that typec is a gimmick, but I want to say that this is the mainstream of the future, and the double-headed type-c is also more convenient for connecting mobile devices. In addition, I have always liked the tri-color keycaps, especially with the white keyboard. This time I finally got a set and I don't have a feeling on the black keyboard.
I have to say that 60% of the keyboard is really very nice and very nice to see, no wonder so many people would rather endure the lack of convenient cursor area and digital area also have to pit.
Do not look at the keyboard is small, the design but intentions, the side can see the high and low keycap design to form a curve, in line with ergonomic design, typing more docile. 
The width of the keyboard is not as good as my mouse! In addition, as mentioned above, the entire keyboard has become very small due to the removal of the cursor area and the digital area. A large area is left on the right side and the mouse is more comfortable to use.
The left side of the keyboard is the same as the normal keyboard, but the right win key and menu key are changed to Fn and Pn keys to realize the full keyboard function.
Turn to the back to see there is mystery, usb type-c positive and negative plug design makes the data line routing line optional. But to tell the truth, this pattern design on the back is not very understandable, not as good-looking as it is, and it has destroyed the overall simplicity.
Turn to the back can also see the poker2 hidden nirvana: the keyboard at the right there are six dial keys can change the layout of the keyboard key bit allocation.
The other keys are not used by most people, but it is still very useful to turn on the independent keys (shift, fn, pn, and ctrl in the lower right corner are used to achieve the upper, lower left, and right, respectively). Another thing to say is that the programming function of poker2 is very powerful. It is simply powerful and tedious.
The specific function I do not extend, in short, is to use Fn + right shift to switch the keyboard state, through the space bar inside the led lights to distinguish between different states, each state can set custom buttons. However, powerful and powerful, practical and practical is another matter, and do not say that ordinary people do not have to use, even if the use of the three layers of custom keys who can remember to live without confusion, and because the three layers can only rotate Every time after switching from the normal state, it must be pressed three times to return to the normal state, and the operation is also quite cumbersome. Personally feel that this feature is somewhat simplistic, even if the custom is also a layer, with three custom brain capacity to be large enough, with the back of the dial button to engage in is not crazy, but also use the keyboard ? It is not as practical as soft programming, or IKBC should be equipped with corresponding software, so that each switch can intuitively see the status of the keyboard keys.
Pull out the keycap can see three led lights, one is the caps lock indicator, the middle is to switch the custom layer indicator (three kinds of three custom color layer, when the default state is not programmable), the rightmost It is a warning light when programming. What I want to say is that since poker2 uses opaque pbt keycaps, these colorful led lights are installed inside the keycap. The effect is really terrible, and it is very destructive to the overall beauty. Fortunately, no custom layer is needed. It usually does not light up.
In addition, mentioning the issue of cleaning is rarely mentioned. The keyboard is actually a place that is easy to filth and is inconvenient to clean. Before entering the pit of the mechanical keyboard, the deaf person has been washing the keyboard with water, and it is very convenient to flush it when it is dirty. The mechanical keyboard does not seem to be really waterproof at the moment, but like the pirate ship k70 is directly under the metal panel, with the brush directly out of the dirty thing. However, there is a rim on the edge of the ikbc keyboard. There is basically no good way to clean it. You need to use the artifact Dyson, or remove the keycap completely.
Third, the use of feelings and summary
1, the keyboard is small and exquisite, the work is solid, the value of the face is quite high. The benefits of the keypad were experienced for the first time. Sure enough, the range of movement of the elbow was reduced a lot, and there was no apparent discomfort when writing this review after turning on the independent arrow keys. In addition, after the keyboard is reduced, the desktop typing feels more comfortable than on the keyboard shelf, and because the keyboard occupies a small space, the mouse is more comfortable to use. However, individuals do not think that it is not appropriate to work in a digital area. In particular, it is often necessary for the office family to frequently contact with forms and numbers to consider carefully. In addition, the delete key is also integrated in the backspace, and the shift+delete key that I often use cannot be used (I don't know if it is a bad habit). It is recommended that you can use the pn key to implement the default layer key customization. In addition, it needs to be mentioned that the ikbc keyboard will feel quite heavy when it is first obtained, giving people a solid feeling. Of course, the disadvantage is not suitable for portability.
2, the original axis with ikbc conscience ptb keycap, feel good as always. At the beginning, it was the tea shaft. Because one of the keys was bad (pressed to not react), the result changed to a green axis. Regarding the feel of the shaft, it will not be repeated. Selecting ikbc will not disappoint you, except for picky and money parties. However, this time around, it seems that several valued friends have encountered problems and replaced the keyboard. It may be that the initial quality control is still somewhat problematic. As a result, I submitted the report one evening later and replaced the beloved tea shaft with the green axis.
3, the donation of the keycaps and the dual data cables all reflect the sincerity of the manufacturers. Before the three-color key cap I want to buy in Ma Yunjia found very expensive, but the red, green and blue tricolor keycaps with white keyboard will be more beautiful. The other two data lines may not be as convenient as data lines plus adapters. Of course, the data cables are not as good as wireless. Such a small keyboard drag line is not very good-looking. There is a Bluetooth version just fine!
4, the back of the dial button can be changed to meet the diverse needs of the keyboard distribution. In particular, it is possible to achieve absolute praise of the independent arrow keys (shift, fn, pn, and ctrl in the lower right corner to achieve upper, lower left, and right, respectively).
5, three custom layers, willful custom keys, feels ridiculous, but not practical. The operation is cumbersome and the three custom layers really need to use to test brain capacity. The improvement suggestion is to provide supporting software to make the custom layer and key programming more intuitive, and it is not so confusing to display the custom state of the keyboard in real time. In addition Pn key tasteless, only useful when programming, hope to update the firmware to improve the experience. (But the scorpion people use it as a direction key anyway, compared with the direction key is the most practical)
6, under the key of several led lights effect destroys the overall style, but fortunately usually usually extinguished, I hope the next version can optimize the design.
7, is not the shortcomings of shortcomings, cleaning inconvenience.
