Recreating a missing wireless keyboard dongle with NRF24L01If your girl friend is that tied to the keyboard buy another wireless and replace the transmitter from one...

I never thought that I would have a strong interest in electronics - this is after I have used a few keyboards. A few years ago, I was freelance at home and made a living by coding. At that time, the slight stuttering of the keyboard frequently interrupted my smooth thinking, so I complained to the network administrator at home—my husband. It was his match. But he was indifferent, and didn't think there was any problem with the more than one hundred Logitech keyboards. So I did it myself, and bought a "PLUM NIZ static capacitance keyboard" at a huge sum of more than 500 yuan under the recommendation of a friend. From then on, typing is extremely smooth, no more worries. But unexpectedly, after a few years, my husband bought two keyboards. He said that one is for home use and the other is for his work. This aroused my indignation, why? Why do you have to use such a good keyboard to play games, but I can't have a good horse and saddle for typing and running a self-media business? Look at his two keyboards again. The ones used by his work unit are actually white and pink. Is it appropriate to look so good-looking? I use a black-gray keyboard at home, but it has RGB backlighting, and the letters and numbers on the keycaps are still transparent, allowing colorful backlighting to show through. I admit I'm jealous, I also want such a good-looking keyboard. So, under the comprehensive consideration of my husband's staff and me, I bought another IQUNIX, green axis RGB. More expensive, six or seven hundred dollars. And this time, I am super happy to win the Durga experience, and I can't wait to share this keyboard with you. Durga's keyboard is great. After a Japanese colleague of mine came to work here, he bought an office keyboard for himself on Taobao to replace the company's original keyboard. He bought the Dujia keyboard. He, who needs to use CAD every day, told me that this keyboard is very easy to use, and it is much easier to use than the original one. My model is Dujia TAURUS K320, the keyboard is black and dark gray, and the red axis is matte, which is a more classic style. The so-called green axis and red axis refer to the axis body under each key. The Cherry MX axis used in this keyboard of Dujia is produced by the German company CHERRY. The cherry switch is very famous and has a long history. It is the originator of the mechanical keyboard. It has stable quality control and is expensive, and is mostly used in high-end keyboard brands. The quality of the shaft body is an important factor affecting the typing feel. The pressing down is smooth, silky, and elastic. The mechanical switch of hundreds of yuan feels really different from the ordinary keyboard switch of more than 100 yuan. You will know it after trying it. Moreover, the cherry shaft not only feels good, but also has a long lifespan. In a word: the old brand is trustworthy. After all, no matter how good the keyboard feels, it won’t work if it breaks after a few months of typing. Then, the green axis and the red axis are different types of axes of the same brand (different brands have different definitions). In addition to the green axis and red axis, there are also tea axis, black axis, white axis and so on. Each shaft has its own characteristics and has a different feel. The red switch is more common, with a smooth and light feeling; while the green switch is a bit like an imitation typewriter, with a "click-click" texture, which is more crisp and has a sense of paragraph. It's hard to describe the feeling of this paragraph, but the feeling is really very different. Some green switches may be too noisy, but red switches are generally accepted, and are suitable for typing and playing games. Therefore, the typing experience with different axes is completely different, and it will be really addictive after using it. I can understand why digital controllers buy keyboards and buy one after another. The more I use it, the more I want to have more... The texture of the keycap is also one of the factors that affect the feel. Dujia is a PBT keycap. PBT is a very hard plastic with high strength, anti-aging and very stable. The hand feel is slightly rusty. The one my husband used at home should be made of different materials, and it feels lubricated. In short, this Durga K320 keyboard is of excellent quality, classic style, comfortable hand feeling, and very easy to use. In addition, let me introduce again, this K320 has a sister model K310, the difference is that the number of keys is different. K310 has the number keys on the far right, which is more suitable for office scenes, and it is very convenient to input numbers. And I chose the K320, which is a bit shorter and lacks a digital module, because I mainly use it for writing at home, and I don’t use many numbers, so I prefer small ones. You can take what you need according to the situation. And the last point, this keyboard supports Bluetooth, wireless and wired, it can be used in any way, it is very convenient. The price does not exceed 500, and the overall cost performance is very high. To be honest, buying a favorite and easy-to-use keyboard is really necessary for people like us who use computers all the year round. You see, even a girl like me who doesn't play games is almost becoming a keyboard user. Finally, one more word of nagging. When choosing a keyboard, you will generally consider the three dimensions of appearance, quality, and price. Usually, the higher the appearance and quality, the more expensive the price. Dujia’s is relatively ordinary in appearance, but its quality is guaranteed. , also use the keyboard with cherry switches, as long as the appearance value is a little higher than this, the price will follow. Therefore, if you have a larger budget, you can consider the ones with higher appearance, and if you have a smaller budget, you might as well consider the quality and feel first. After all, the most important thing is to use it conveniently.

This is the second part of [Old Object Evaluation]. The mechanical keyboard clicked, and I double-clicked to scratch the wall later. The island keyboard has poor rebound, and the typing speed is as slow as flying. The Bluetooth multi-link design is good, and it is a bit frustrating to be indistinguishable. ThinkPad is a true god, with a long life span of ten years. As the time stretches to ten years, the use of keyboards keeps changing, and personal needs change constantly. I bought a lot of keyboards back and forth, because the price/performance ratio (poor) is not expensive. I threw away a lot, and after cleaning up the cabinets, there were still a few left, so I just took them out and counted them. At first, I pursued usability, and then I pursued key travel, rebound, stability, etc. I wanted a feel, and then I wanted to connect more with Bluetooth. The ultimate pursuit is back to typing quietly. But the demand keeps falsifying. Although it is not a fall into the trap of consumerism, but after going around, I found that the keyboard at the beginning is the one that gives me the most companionship and the most comfort. The main reason to buy a mechanical keyboard is to play games. want is feel , the persuasion is double click and too noisy 。 My aunt has been shopping a lot, and she has always been so excited to play games on a mechanical keyboard. I was obsessed with DOTA2 again (veteran with 2502 hours of game time, an elite who has scolded 9 players with 1 person, and a current cloud player who is worried about why he didn't ban Mammoth). I listened to the propaganda of an unknown forum before, so I bought a splash donkey for more than 100 yuan. After using it for about half a year, double-clicking + certain keys failed, so I threw it away. In Xianyu, I bought a defective entry-level keyboard from a well-known "big factory" - Rapoo V500PRO. It only cost 65. Sure enough, in less than half a year, the most commonly used enter and space have been double-clicked. Playing games is actually okay, but typing is completely unbearable. Works okay but breaks down fast According to my immature experience, the rebound of the mechanical keyboard is really good. It really feels like a leap when you start using it, but it will be the same after a long time. And the feel of a good membrane keyboard is not bad. The first disadvantage is a common problem, that is, it is too noisy. When I started to use it at home, every night in the dead of night, when my left hand went up and down the range to show the audience, my wife often unplugged the power directly. The second disadvantage is that it is easy to double-click. This may be because my entry is too low-end, and it may not be a common problem. Later, I used it in the office, and was almost beaten to death by my colleagues when I worked overtime at noon. Cloud players are gone, mechanical keyboards will no longer be used, and I envy those teenagers who still love light pollution, DOTA, and LOL. The island keyboard I understand is a keyboard separated by one key, and the function positioning is mainly in pursuit of thinness. Most of the island keyboards are bought passively, and a small part is bought to meet specific needs. The feel is too bad to say anything. I bought several notebooks one after another, including the stupid Shenzhou God of War, the more refined Lenovo Xiaoxin, Apple’s macbook PRO, the Rapoo K480 for typing on the iPad, and the Rapoo K480 for wireless and mute. The K8100M keyboard and mouse set. Strictly speaking, it should not be all isolated island keyboards. The main reason for being classified into one category is that the hand feel is equally bad, so it is convenient to complain together. I don't mean anyone, I mean island keyboards are rubbish Where is the difference? most importantly key travel is too short . That is, the maximum downward pressure distance of the keyboard is very small. The short key travel causes the keyboard to go to the bottom as soon as it is pressed. I have not exerted force, and you are over? followed by Poor rebound effect . When the letter is pressed, it takes a moment to rebound, which is similar to the feeling of playing Dota with a delay of 100 milliseconds. after all it is Not nice to use. It can only be barely used in an emergency, and if it is used for work for a long time, it will definitely be rushed to death. True love life, stay away from isolated islands. Rapoo's K8100M and K480 are both Bluetooth multi-connected devices. The original intention of purchasing them is to use them for typing on IPADs, mobile phones and Huawei tablets in the future. In other words, this demand is all imagined out, and it is actually useless. The software on the tablet and mobile phone is still suitable for mobile emergency office, and sitting at the desk to work seriously is still far away from the PC. Speaking of Bluetooth multi-connection devices, for me who is confused, the biggest pitfall is that when I use it occasionally, I really can’t remember which device 1, 2, and 3 are. The K8100M has a key to distinguish devices, and the Bluetooth has a slight delay. It takes a while to switch to the correct device connection. Every time I always think that the switch is wrong, resulting in continuous switching and always failing to connect. You have to reconnect every time you use it. The K480's physical scroll wheel switch is okay, and there is a wheel that can assist in memory. K480 has a physical switch wheel, which is much easier to use After rambling so much, it's finally the turn of the player I'm going to praise to the sky. Dangdang, THINKPAD X220. Fighting for ten years, the glory is still I remember when I first started ten years ago, it really surprised me. The notebook was small, thin and light at the time, and the little red dot in the middle of the keyboard gave people a sense of confidence. As the battery wears down over time, this small notebook is placed on the desk and used as a desktop computer. However, the more devices I have used, I found out after a comparison that when it comes to keyboards, other young devices I have experienced are really only worthy of a sentence of rubbish. On key process , can’t reach the length of a mechanical keyboard, but it’s enough, and it can have enough distance to exert force when pressed. on rebound , not as hard as a mechanical keyboard, but the rebound is very fast. Perfect for my hand speed. on button , the head is too big, with a slight curvature, and the pressure is smooth, and there is no feeling of falling down. Moreover, ten years later, the feel is the same as before. Although the little red dot has always fallen down, although one of the touchpad buttons has fallen off. But this keyboard still rebounds strongly and responds quickly, like a loyal partner, diligently accompany me to continue fighting. The initial thought is that I'm going to have him stay with me until the last day he can work. Sigh, is it worth sacrificing the feel of the keyboard in the pursuit of thinness?

Actually, I don’t know much about the brand of Keychron. Forgive my ignorance. I feel unfamiliar. I searched on Baidu and found out that this brand is a very popular keyboard brand abroad. Later, I learned that Keychron is also a domestic brand. A manufacturer made in Tokyo, keychron's perfect system switching function, various details designed for MAC users, and rich experience in peripheral products make me feel that its keyboard is still worth a try. This time I started with the Keychron V5 mechanical keyboard, let’s experience this keyboard. Appearance Gallery ▲Outer packing box, I searched it, and its packaging style is really uniform, with a black background color picture, a tough and simple style, and the packaging also clearly tells you that this is a 96% keyboard . Do you like this arrangement? ▲The random accessories are very rich, including supplementary keycaps, key pullers, shaft pullers, power cords, screwdrivers, and replacement screws. ▲Take out the first impression of this Keychron V5, and you will give it a score. The square shape, especially the tough corners, corresponds to the rounded keycaps. The combination of black, gray and red keycaps will bring a touch of jump to the dull colors. ▲This Keychron V5 uses a black plastic shell, and the integrity is still very strong. In terms of configuration, this keyboard uses a 96-key configuration, retaining the keypad + imitation metal knob. ▲However, compared with the conventional TKL arrangement, it adds a programmable metal knob at the corner. It can be used to adjust the volume, etc. ▲ Viewed from the side, the edge of the keyboard adopts a concave design. This design makes the keyboard look thinner visually, and it is more convenient to take. ▲On the top side, you can see the Type-c interface to switch the WIN/MAC system. ▲Turn it over, the design on the back of the keyboard is very simple, without a trace of extra fancy, the foot support adopts a two-stage structure, which can meet the needs of different users. experience feelings ▲ In terms of the switch body, Keychron V5 uses the self-developed K pro red switch. In terms of hand feeling: the built-in factory run is excellent in both smoothness and stability. At the same time, the touch of the red axis is straight up and down without pause, and the rebound is softer and softer. The hand feel is similar to squeezing cotton. In general, typing feels continuous and pressing feels light. ▲The keycap is a standard pbt material with an osa height. The spout of the keycap is well handled and the space does not have obvious seesaw phenomenon. The reprocessing here is still good. ▲The position of the big key adopts the uncommon PCB satellite shaft. Compared with the steel satellite shaft, it has great advantages in terms of stability and structure. Because it is fixed by screws, it will be much stronger than the steel plate satellite shaft. You don’t have to worry about the satellite shaft being too loose or too tight due to inconsistent cutting of the positioning plate. The disadvantage is that it is more troublesome to adjust later, because the satellite shaft is fixed first and then Carry out positioning plate installation and shaft body installation. Gold-plated screw satellite shafts are also used. The cost seems to be much higher. ▲In addition, in order to improve playability, the five pins are hot-swappable. Full-key hot-swappable, if it is compatible with three-legged and five-legged shafts, it can generally be compatible with many shafts on the market, and you can use the shaft puller to plug and replace shafts from different manufacturers to experience the feel. ▲Compared to the original or OEM keycaps, this type of ball cap There is no uncomfortable feeling in use, this Keychron V5 has WIN/MAC dual system switching function, ▲WIN/MAC dual system switching function is still very convenient when working, and all kinds of switching are well known. ▲In terms of customization, this keychron V5 has two programming methods, QMK and VIA, through software control, you can realize custom button settings and quick settings. ▲This is the charm of customization, every part can be customized according to your own preferences. ▲As a keyboard with personality, RGB lighting effects are certainly not missing. However, the keycaps are opaque, and various styles of lights are waiting for you to debug. Summarize If you want to find a mechanical keyboard that is suitable for office work and games, easy to use and fun, this Keychron V5 is worth a try, the price is not expensive, and there will be different surprises.

I don't know where to start, I became interested in ergonomic keyboards, maybe my wrists are uncomfortable, maybe it's just my yearning for new things. I have used Microsoft Sculpt, Goldtouch, Microsoft surface ergo, and later used split keyboards Ergodox, Ergodone, and even Truly Ergonomic keyboards, KINESIS Advantage also received second-hand experience. Gradually, I was always looking for a main keyboard. The key was not to worry about it. At that time, I had an X-Bows (it seemed to be called Pterosaur at that time) in my cabinet, and I pre-sold X-Bows on zFrontier. I bought the Nature/knight keyboard, and this became my main keyboard. In the past two years, at home, this is my main keyboard-X-Bows Nature Later, considering that the workplace and home should be equipped with the same keyboard, I bought X-Bows from various channels, and changed the axis and bottom case myself, which is suitable for different scenarios. This is one of them. The yellow axis of Jiadalong was replaced, and the unit was considered to be silent, so it was replaced with a silent axis. Do-it-yourself wooden base No matter how many I have changed, I have always regretted that there is no Bluetooth. At one point, I almost planned to use the Ergodone Bluetooth version as the main keyboard. In fact, I just wanted to make the table clean. A few days ago, I found the (Pre-sale) X-Bows Crystal Programmable Ergonomic Wireless Mechanical Keyboard on the X-BOWS official website when I was casually browsing. Isn’t this exactly what I want? I contacted decisively and made a reservation. I wanted to shoot a video as soon as possible, but I have been busy with work recently. I opened it today and felt it, and wrote down my feelings and thoughts. Let's take a look at the keyboard first. The photos are not good. There are pictures on the official website and there must be videos from the follow-up bosses. Same as the official picture front Back Made in China Nice acrylic case There is Bluetooth and Type C Turn on the light to see, it looks very beautiful, and it will be more beautiful at night. Although I usually don't turn on the light, it's the same thing if I don't need it. 16.8 million colors RGB backlight + transparent acrylic body Of course, when it comes to keyboards, different people have different opinions. At least for me, this Bluetooth version of X-bows is still what I need. Next, I will use this keyboard to briefly talk about my feelings about this keyboard. Since it is from the perspective of personal feelings, it may not be in line with everyone's views. advantage: 1. There is bluetooth, there is bluetooth, there is bluetooth; 2. You can update the configuration file of the keyboard by yourself, which is simple and convenient; 3. Acrylic looks beautiful with light added; 4. The whole is very thick, compared with the previous version, this version can fit more keycaps; 5. For users who have never used X-bows, the learning cost of this version of Crystal will be lower. Personal feelings: 1. For users who are very familiar with X-bows, it still takes a little time to get familiar with it (I have adapted after writing this, I don’t know if I will touch it by mistake when I return to Nature), after all, there are still some gaps between the distance and position of the keys and before. Yes, you will always accidentally touch CAPS, etc. After all, these keycaps have become larger. Of course, this position may be more friendly to users who used ordinary keyboards before; 2. The INSERT in the upper right corner defaults to DEL, but there is no keycap. It is recommended to have several spare keycaps for users to replace. It is also recommended to have a few replacements, as well as PAGE UP and PAGE DOWN; of course , give a few spare axes if possible; 3. As for the keycaps, I still prefer the feel of the previous keycaps. Of course, the keycaps after this arrangement are more standard, and some other keycaps can be selected; the keyboard is a bit high overall. If there are users who like to use SA keycaps , After trying it for a while, it is still a bit tiring not to use the palm rest. It is recommended to equip it with a keyboard palm rest. 4. Visually, this keyboard will be more difficult to clean in the future, which is also the price of good looks. Imagine: For a loyal X-bows fan, of course, he would like to continue the Nature/lite/knight configuration to upgrade the Bluetooth version, maybe because he is used to this configuration. There are also some other ideas, such as whether the Bluetooth upgrade can be implemented on the original Nature/lite/knight keyboard, and some accessories and tutorials can be released, so that players who are willing to DIY can transform it by themselves.
