Hello everyone! I am Young Master Shen! As a keyboard player, if there are novel and interesting products on the market, I will try my best to test them as soon as possible. What I brought today is a very special gaming mechanical keyboard, Shuangfeiyan's "Blood Hand Ghost 3 Player 3 Variable Speed ​​Optical Axis Mechanical Keyboard T98", I have to say that the name of this model is really a bit long. The biggest highlight is naturally the adoption of the LT variable speed optical axis, which realizes the effect of one button and three speed changes. Let's take a look at the details together!

First of all, let’s take a look at the appearance of this keyboard. Personally, I feel pretty good. The overall 98-key design can take into account the compact shape and comprehensive key functions.

The workmanship and materials used in the details are also quite good. The keycaps and the keyboard shell have been finely chamfered, which feels good in daily use. In the lower left corner, there is also the recognizable logo of Shuangfeiyan Bloody Hand Ghost series and the slogan of BLOODY ONLY FOR GAMES.

The overall design of the keyboard is very integrated, and the most eye-catching thing is the red "LT" key. Let's talk about it later.

The interface on the back uses a Type-C interface, and there are three-way cable management slots. In this way, everyone can choose the most suitable wiring method according to the layout of their own desktop, which is very useful.

In addition to its own ergonomic tilt angle, there are also 2 sections of feet to choose from. It should be said that this keyboard provides us with a lot of space in terms of placement.

Let’s take a look at the keyboard accessories. First, there are 25 game-oriented PBT keycaps, OEM height.

Because it adopts the sublimation process, it not only has a delicate feel, but also is not easy to oil.

In addition, there are 3 switches and a key puller, so that you can feel the details of this special switch, and replace the keycaps by yourself to create a personalized keyboard.

Of course, the most anticipated thing about this keyboard is the actual experience. First of all, this 3-speed trigger stroke is really magical and easy to use. The three different gears can be distinguished by the color of the keycap backlight, which is very intuitive. For example, when I play games, I will switch to red, that is, to trigger the super fast 1.0mm stroke. In CSGO and other competitive games, the continuous jump, emergency stop, and strafing transfer are all more handy. No matter how I operate the keyboard, I will respond.

At the same time, for the relative operation of writing code, which is relatively fast, but not as extreme as playing FPS games, I can easily use the middle gear, that is, the yellow light. With a trigger stroke of 1.5mm, it is still faster than the common standard 2.0mm stroke, and you can record it immediately when inspiration comes.

As for daily surfing, chatting, etc., just use the standard gear, and the 2.0mm stroke of the blue light is enough.

In addition to being able to switch freely between the three gears, Shuangfeiyan Bloody Hand Ghost specially made this "LT" button, which is very convenient to easily switch with one button.

It is indeed very convenient and intuitive to cooperate with the prompt of the keyboard backlight just mentioned.

At the same time, this keyboard is relatively small and compact among the full keyboards. When the light is good, the color is that kind of grass green, very fresh.

In low light, it is a darker green color, and it has a "combat sense" when playing games with the backlight. Thanks to the 98-key design, the number lock, caps lock, and game mode indicators are not reduced, so it is quite convenient to use.

Seeing this, there must be many friends who are very interested in this magical LT optical axis with 3-speed trigger travel.

The other principle of this shaft is to define the position of the trigger point and reset point through 3 gears, and then use the curve change of the trigger pressure of the shaft itself to create 3 different operating feel. It also achieves the goal of being able to switch directly and quickly between the 3 kinds of feel without changing the axis of a keyboard.

In addition, the stability of the shaft body itself is also good, and it is still a light-transmitting design, which is indeed very interesting.

In addition to its own variable trigger stroke, this keyboard's shaft body has another feature, that is, the reset is almost at the same point. For our use, the combo speed is super fast. In CSGO, the quick gun or props can be cut. Very smooth and feels full in the hand. This is why it is said that this keyboard is especially suitable for hardcore gamers, and it really fully exploits our operating level.

At the same time, in terms of the specific feel, I personally feel that this switch body belongs to the mechanical feel of the red switch + the smoothness and quietness of the pink switch. It is quieter than most mechanical keyboards, and it is not easy to disturb the surroundings. It is also very suitable for people who write code quietly at night alone.

In addition, due to the use of a very stable shaft core, the swing angle is small and the deflection angle is only 0.5°. Moreover, the shaft body has a life of 100 million keystrokes, which is very durable.

In addition, there is a sound-absorbing material inside, which further reduces the noise. It is equipped with splash-proof water, all keys without punching, Windows lock, and multimedia shortcut keys. These special functions can be said to be not only suitable for playing games, but also a very versatile mechanical keyboard. .

If there is room for improvement, I decided that the lighting effect of the keyboard can be more varied. For example, after the LT key switches modes, the current working status can be prompted through a monochrome backlight, and then it can be replaced with a mixed light or RGB marquee light. The effect is to give players more choices. In addition, it would be even better if the function of wireless connection can be added in the future.

Generally speaking, the keyboard of Shuangfeiyan Bloody Hand Ghost is really interesting, and the 3-position adjustable gameplay brought by the LT optical axis is also eye-catching, and it is really easy to use. Coupled with its good feel, key experience, and compact full keyboard design with 98 keys, it is a mechanical keyboard with excellent gaming experience and quite versatile. In terms of specific choices, mine is a pixel green color scheme, which is very beautiful.

If you like a more cool style, there is also a pixel gray color option, and the functions are also rich, and it is worth starting.

Titanium is a brand founded by Renhuang SKY. It mainly deals in peripheral products such as keyboards, mice, earphones, and monitors. The cost performance has always been outstanding. This time I bought the Titanium K850 Caixishi mechanical keyboard. This is a wired keyboard with 98 keys. It uses the RoBeetle mechanical armor red switch, and supports hot-swapping of all keys, and also supports RGB backlight effects.

The packaging box of the Titanium K850 Caixishi mechanical keyboard is very simple and environmentally friendly, with only the Titanium brand logo on the front.

The box contains: Titanium K850 Caixishi mechanical keyboard, key puller, replacement keycap, Type-C data cable and instruction manual.

Titanium K850 Caixishi mechanical keyboard is designed with 98 keys, the size is 380*133*39mm, which is about 40mm shorter than the usual keyboard, and the overall layout is very compact.

Compared with the usual 104 keys, the 98 keys have reduced some function keys that are rarely used, so basically it will not affect the normal use of the keyboard. On the left side of the bathroom digital keys, there are four indicator lights including the common NumLock and CapLock, and there are also indicator lights for the win key and all the keys.

Use the attached key puller to remove the keycap. You can see that the mechanical switch uses RoBeetle red switches, and the two sides of the large key are equipped with factory-lubricated satellite switches. The feel is still good.

After pulling up the switch body, you can see the PCB board at the bottom, with SMD LED lamp beads on it. The hot-swappable design can greatly improve the playability of the mechanical keyboard. After all, everyone has their own favorite switch body. The pluggable design allows you to change the shaft body at will according to your preferences.

The Titanium K850 Color Master mechanical keyboard is designed with separated key lines. On the top of the back of the keyboard, there is a three-way design of the wire groove. This design is very friendly to the appearance of the keyboard.

Titanium K850 Caixishi mechanical keyboard is also designed with two adjustable brackets of different heights, which can lift the front end of the keyboard to different heights, which can make the keyboard more comfortable.

Titanium K850 color player mechanical keyboard is also equipped with a set of flame core keycaps.

After connecting the Titanium K850 Color Gamer mechanical keyboard to the computer, the LED backlight system of the keyboard will automatically light up.

The lighting effect of the Titanium K850 Color Master mechanical keyboard is still very good.

The brightness of the SMD LED lamp beads on the PCB is very good.

Titanium K850 Color Master mechanical keyboard has an independent management software. The home page is the lighting management. You can see the current lighting mode and effect of the keyboard on the software. Here you can customize the color, brightness and speed, and there are preset 18 A variety of lighting effects can be applied directly.

The following is a display of some of the preset lighting effects of the Titanium K850 Color Gamer mechanical keyboard.

In the key setting page, you can modify the default function of each key, and you can set other key functions, combination key functions, multimedia key functions, system functions, basic mouse functions and macro functions. The settings of the buttons are still very rich.

The macro management page can manage macros, such as recording, editing or deleting macros. The macro function can completely record various operations for a period of time, and then set it to a key through key management. Just press it to output the macro. All operations are recorded, very convenient.

Other settings can lock windows keys, set keyboard properties, and set USB return rate. On the management software, various configuration files can also be configured, uploaded and downloaded.

It is also very nice to replace the flame core keycap that comes with the accessories.

The Titanium K850 Color Gamer mechanical keyboard feels good whether it is for games or office work.

The price of Titanium K850 Caixishi mechanical keyboard is less than 200. It has a compact layout of 98 keys, is equipped with factory-run large keys, supports full-key hot-swappable, has RGB backlight system, and has 18 preset lighting effects. Said the price/performance ratio is still very good. Looking forward to the appearance of multi-mode versions in the future.

Wandering around in Xianyu, I accidentally discovered a certain trash guy hanging out a Fujitsu cord-cutting keyboard. The seller did not mark the model number of the keyboard, but from the blurred writing on the back label paper, it can be seen that this keyboard is the legendary king of membrane keyboards FKB-4725. I haven't played with Fujitsu's keyboard before, so I gave it a try.

When I got it, I found that the keyboard was quite dirty and covered with dust. Although the keycaps are complete, the ESC key has been broken. Pressing a few buttons casually, the experience is very bad, and the jam is serious. I also bought an IBM Model M before, and the buttons of the Model M are still very crisp and neat even when it is covered with dust. The legendary film king, is this level?

The shell of this keyboard has no screws at all, and the upper and lower covers are connected by snaps. Use a crowbar to carefully pry open the buckle, then you can separate the upper and lower covers, and take out the inner tank in the middle.

The moment I saw the liner, I deeply felt a chill down my back. In addition to the serious dust in the keyboard, the steel plate is also seriously rusted. If it can rust like this, it is likely to have been in water, or it has been stored in a humid environment for a long time. This time, there is a high probability that the car will overturn.

The main control circuit board of the keyboard is positioned on the back of the steel plate through screws. The membrane circuit of the keyboard is connected with the main control circuit board through the membrane cable. On the far right of the main control circuit board, there is also a 5P plug, which is connected to the keyboard cable of the PS2 interface.

Take a closer look at this rotten ESC key. It can be seen that the top of the box board is covered with dust, and the steel plate underneath is also rusty. The key sticking is probably due to too much dust ingress, resulting in serious friction between the key and the guide rail. Since several keys could not be played, I decided to clean the keyboard first, let the keys recover, and then test whether the keys are good or bad.

This Fujitsu Peerless button, like the IBM Model M, has a double-layer keycap. But its keycap is tighter than that of Model M, and it is not easy to pull out. The upper keycaps of the Model M can basically be broken off with bare hands, while the Fujitsu peerless has to rely on a cap puller. According to my personal experience, using a cap puller like the one pictured above is easier to insert into the keycap because of its thinner outer wall.

It is easier to pull the cap puller stuck at the upper and lower ends of the button than at the left and right ends. First, put the cap puller in a position a little to the left, pull it out, and pull out the left side of the keycap, then move the cap puller to a position a little to the right, and pull out the right side, so that the entire keycap is completely Pulled out.

Its big key is buckled on the bottom keycap on one side, and inserted into the next cylinder through a round rod on the other side.

The keycaps that were pulled out were really dirty. Take a bath with the advanced ultrasonic cleaning machine.

Under the action of ultrasonic waves, a large amount of dust immediately muddied the water.

The keycaps on the bottom layer are stuck on the top of the casing board through buckles, and it is difficult to pull them out if they are hard to pull out. You need to use other tools to pry the buckles. But because there are both left and right sides of the buckle, if you pry the left side open, the left side will slide back if you are not careful when you get the right side. Since it is too difficult to handle, let's first disassemble the steel plate on the back to see if it is better to remove it from the back of the box board.

Unlike Model M, Fujitsu's steel plate and casing are fixed by screws and buckles and are detachable. However, there is a huge problem here, that is, due to the rust of the screws, several of them have slipped. In the end, I had to use an electric grinder to re-carve slots on a few rusty screws, and then unscrew them with a flat-head screwdriver. It took a full night to remove these rusty screws.

Remove the steel plate, and there are two layers of thin film circuits underneath. It can be seen that the rust stains on the steel plate have also corroded to the film.

Remove the film, and you can see the bobbin board and the rubber bowl layer.

Under each lower keycap, there is a short spring. There is also a section of white tube under the spring, which is used to press down the rubber bowl, so that the two layers of film are in contact to complete the triggering of the button.

The key structure taken from the front, upper keycap--lower keycap--spring--white tube

After completely removing the plastic bowl, spring and other accessories, I studied it and found that it is easier to pry the lower keycap with a long and thin hard object extending from the back of the tube board. When prying, pull the keycap up with one hand to prevent the snapped buckle from sliding back, and then quickly pry the buckle on the other side.

It took another two hours to pull out all the lower keycaps except the space. There is a balance bar on the blank, and the balance bar is stuck on the top of the tube board. I was afraid that the balance bar would be damaged when pulling out the keycap, so I didn't touch it. And the space bar itself is not too astringent, it is estimated that it can be washed with water.

All keycaps are cleaned with an ultrasonic cleaner. Rinse the entire cheese board with a tap, and then brush it with a soft brush. The keyboard is cleaned and the keys are finally not jammed. Ready to try the keys. This keyboard has a PS2 interface and cannot be connected to a laptop. A PS2-to-USB converter is required. Before connecting to the converter, you need to determine the line sequence of the keyboard.

Here also share the method of determining the line sequence of the PS2 keyboard. The primary goal of determining the line sequence is to determine which is VCC and which is GND. The two poles of the power supply are confirmed, and the keyboard will not burn. It can be seen that there is an electrolytic capacitor next to the 5P keyboard cable socket. This large capacitor is usually directly connected to both ends of VCC and GND to stabilize the input voltage. Use the on-off gear of the multimeter to see which terminal on the 5P socket is connected to the positive and negative poles of the capacitor, and you can judge which is GND and which is VCC.

Even without a multimeter, the positive and negative poles of the power supply can be judged through the lines on the circuit board. It can be seen from the circuit board that there are two sets of lines that are particularly thick, and these two sets must be the positive and negative poles of the power supply. On the far right of the circuit board is a large metal ring (tinned copper?), which is used to conduct electricity with the steel plate on the back, and is a shielding layer. The shielding layer is connected to the left layer of wiring through the front wire, and finally connected to the second and third pins of the socket. It can be judged that the second and third pins are both GND. And the first pin is connected to another very thick line through the front wire, which must be the positive pole of the power supply.

After confirming VCC and GND, CLOCK and DATA will depend on it. If you are not right, reverse CLOCK and DATA. The final line sequence tested is black VCC, red GND, green DATA, and brown CLOCK. The bullshit chip in the picture above is a PS2-to-USB conversion chip, which was removed from the PS2-to-USB converter on Taobao.

Although the wiring sequence of the keyboard was successfully tested, the old keyboard was overturned. Connected to the computer test, it was found that more than half of the buttons were not triggered. Due to long-term moisture corrosion, there are disconnections in many places on the thin film circuit. The most terrible thing is that the wires on the film are covered by a green protective film. If you want to repair it with conductive silver paste, you must first remove the green protective film. There is no way to remove the protective film except for sanding. It is too difficult to use sandpaper to just wear off the protective layer without damaging the underlying circuit.

As far as my personal experience is concerned, I feel that the playability of Fujitsu FKB-4725 is far worse than that of IBM Model M. First of all, Fujitsu's ability to resist dust is far worse than that of Model M, and it is much more difficult for Fujitsu to disassemble the keycap for cleaning than Model M. Even if Fujitsu is in a normal state, its input experience is far inferior to that of the Model M squat spring. Its input feeling is probably on the basis of ordinary membranes. Due to the addition of springs, the keys are more handy when they rebound. I think its input experience is not as comfortable as the large paragraph feeling of a high-quality plastic bowl membrane keyboard.

Men must have hobbies, otherwise it is easy to take detours! My hobbies are fishing and picking up trash! Little yellow croaker accidentally saw a Bastron wireless bluetooth dual-mode mechanical keyboard, missing the cap, missing the receiver, the quality is rubbish, not packaged, no return or exchange after sale! I checked this brand, this keyboard has been discontinued, and the company has switched to industry custom keyboards, but 40 yuan, bluetooth, mechanical keyboard, I think it is still worth buying.

This keyboard should be recycled from the waste station, and it will be disinfected with alcohol, and it will be cool for a day! The power supply is powered by four AA batteries. The original keycap is missing a part, and the color is OK. Remove it and wash it, put it in the detergent water basin, soak it for a day, wipe it with a wet towel, disinfect it with alcohol, dry it and put it away. Put it in a bottle for later use! Start to disassemble, it is very simple, there are four screws on the back, and two are under the foot pads, the inside is okay, there is some grease, spray alcohol, wipe it with a wet towel, dry it, and let it dry in the sun! The battery slot and the main board are fine, but I hope there will be no problems!

I spent another 28 to get a set of keycaps. I didn’t understand it at first, and thought they were all matching. Who knows, this knowledge is still great. After buying it, I found that some keys were missing, and some were not matching. Fortunately, the original one was not thrown away!

Assembled, feels pretty good

Plug in, turn on, Bluetooth pairing, button test, everything is normal! I feel that 68 yuan is still worth it! Two devices can be connected, mobile phones, tablets, and computers can all be used. When playing League of Legends with low power, there will be some delays! But now that I have a child, I don’t play much anymore, so I put aside my original non-branded keyboard and use this as the main force!

Recently, the backspace key suddenly didn’t work today. I tested the phone, but the computer didn’t work. It’s probably a problem with the keys, and I don’t have any extra keys to replace. Prepare to swap F5, which is not commonly used, with the backspace key!

It is not difficult to remove. The electric soldering iron is heated, and the tin suction device sucks it, but the suction is not clean. You can only use a screwdriver to tilt it, and the other side is reheated with a soldering iron, and it falls off. There is a lot of rust on the pins. It is estimated that the keyboard has been exposed to water before. In addition to rust, install the F5, plug it in, test it, and the backspace key can be used normally.

Picking up leaks is risky! But tossing is very happy. When I was young, I couldn’t restore things when I dismantled them. Radios, alarm clocks, etc., I have dismantled everything that can be dismantled. There are either multiple screws or multiple gears. Now I can slowly solve some small problems. It can be restored perfectly! After all, thirty, has grown up!

Hi everyone, I'm Garbage Goodman, thank you for watching
