Dareu’s Zijin Switch update iteration has reached the latest third version of "Zijin Switch Pro". Paragraph axis. The fence-type shaft, PC cover, gold-plated spring and other configurations are gathered together. Next, we will use the combination of pictures and texts to share the experience of using this shaft.

▲Zijin Axis Pro is shipped in cans, which can effectively prevent the shaft from being damaged during transportation, and the cans that have run out of the shaft can also be used for other purposes

▲Zijin Switch Pro adopts the color combination of PC material golden transparent cover + yellow axis center + purple axis seat, and the tripod axis design can adapt to most keyboards on the market

▲The shaft body is composed of the traditional shaft cover, shaft center, spring, and shaft seat. The trigger pressure is 45g, the bottoming pressure is 55g, the trigger stroke is 2.1mm, and the bottoming stroke is 3.8mm

▲The brand-new yellow fence-type structure shaft can make the up and down travel of the shaft more stable, and the factory comes with lubrication. The micro-steps are clear and smooth without being obtrusive. The feeling of quick tapping is very comfortable

▲The extended gold-plated spring used has strong oxidation resistance and quick rebound

▲The gold-plated contacts of the shaft body and the shrapnel are fixed by riveting, which is stable and reliable, and the overall service life is as high as 80 million times. It can be seen that there is a sufficient amount of grease on the shrapnel, and the smoothness and noise are effectively optimized.

This time, the CIY GAS67 hot-swappable RGB keyboard kit and GANSS Jingyuan Xing PBT two-color OEM height keycaps are used together with Zijinzhuo Pro

The CIY GAS67 hot-swappable keyboard kit is not too much to introduce. As an entry-level Gasket structure kit, the user experience is good.

▲The GC series keycaps of GANSS have many colors, the price is affordable, and the quality is very suitable for daily use. Since the shell of the GAS67 kit is black and transparent, this time I chose the Jingyuan apricot color as a match. The total number of keycaps is 139 from 108. Main key position + 23 function key supplements + 8 color matching supplements

▲The keycap is made of OEM highly designed PBT material, two-color injection molding process, and the characters are opaque

The overall feel of the Zijin Switch Pro is good. The micro-paragraphs are smooth and clear, and the factory self-lubricating also makes the travel of the axis smooth and silent. GANSS’s Jingyuan Apricot color PBT two-color injection keycap has a delicate feel, clear characters, and is economical. It has strong oil resistance. At this stage, more and more manufacturers are making keycaps with original factory heights or ball-like heights. As a result, there are fewer and fewer OEM-height optional keycaps, but after you get used to OEM-height keycaps, you can use other heights. The keycaps still need some time to get used to. If there are players who also like micro-section shafts and OEM height keycaps, you may wish to pay attention~

As a peripheral enthusiast, it can be said that I am very familiar with mechanical keyboards. In my opinion, when buying a mechanical keyboard, there are three elements: brand, appearance, and shaft. Based on these elements, I also bought a lot of mechanical keyboards, but even so, when I saw the Dujia K330W mechanical keyboard, I still felt bright: Dujia, known for its good looks, is too avant-garde in design! It truly blends fashion aesthetics and is unforgettable.

Taking advantage of shopping and arrival, I finally bought the Durga K330W mechanical keyboard-ice cream color scheme (four colors in total). Next, share your experience.

Appearance | In addition to super high value, three-mode full-function is also a highlight

First of all, let’s take a look at the design of the Durga K330W mechanical keyboard. From the appearance and basic functions, you will understand why I put the brand factor first in the purchase of mechanical keyboards.

Because it is a 61-key keyboard, the packaging box is relatively small. From the packing box, you can see the elements of Durga, K330W, and ICECREAM.

Packing list: Durga K330W mechanical keyboard, USB-A to C charging cable, key puller, manual.

As a 61-key mechanical keyboard, the Duga K330W mechanical keyboard gave me the first feeling that it is very small in size, with a length of only 30cm and a weight of 530g, which is very delicate.

In terms of color matching, the first impression I get from the Duga K330W mechanical keyboard is that it is full of fashion elements. The basic color is light blue, and with the purple color matching, the breath of youth and fashion comes to my face.

In the upper left corner, 4 indicator lights are designed, which are capitalization indicator, key lock indicator, onboard custom button indicator, and battery indicator, with all functions.

The switch button of the Duga K330W mechanical keyboard is designed on the right side of the top, and slides the switch.

On the left side of the top is the Type-C charging port. The built-in battery of Duga K330W mechanical keyboard can be fully charged in 3 hours, but it can bring 240 days of battery life in Bluetooth mode and 180 days of battery life in 2.4G mode, so there is no need to worry about standby.

Moreover, the charging port can be connected to a PC to become a wired keyboard. Coupled with Bluetooth and 2.4G, the Dujia K330W mechanical keyboard is a three-mode keyboard with many usage scenarios.

Viewed from the side, the exterior detail design of the Duga K330W mechanical keyboard is also excellent, and the sharp-edged lines add a bit of toughness to the keyboard.

At the bottom, the Durga K330W mechanical keyboard is designed with 4 silicone pads + two supporting pads. The 2.4G receiver is designed on the left side of the right supporting pad and placed inside the storage compartment.

After opening the height-increasing bracket, the angle of the keyboard is significantly improved, which is suitable for users with more usage habits.

I have many daily use scenarios, but most of them are still used in the office. So, I chose the red axis that I like more. The red switch of Durga K330W mechanical keyboard is different from that of other keyboards. It adopts the switch body-crystal switch customized by Durga and Jiadalong, which not only improves the feel, but also greatly increases the service life.

Another small detail: As a 61-key keypad, the Durga K330W mechanical keyboard has designed shortcut key characters and icons under some keys, which can quickly execute some commands together with the Fn key.

Here, it not only includes F1-12 buttons, but also includes Bluetooth device switching, multimedia control and other functions, and the efficiency is guaranteed after a little adaptation.

As a mechanical keyboard, Dujia K330W mechanical keyboard maintains Dujia’s consistent high-value features, and is impeccable in appearance, color matching, and details; at the same time, long battery life and customized switches can also ensure daily use experience.

User experience | Multi-mode usage scenarios are rich, and the feel is adjusted in place

After reading the appearance, let me share the actual use experience of the Dujia K330W mechanical keyboard.

As mentioned above, the Duga K330W mechanical keyboard itself supports software settings. On the home page, you can see that you can adjust the keys and Fn key combinations separately. At the same time, the remaining power of the keyboard can be displayed.

In the detailed settings of the keyboard, you can see that not only a single key supports setting, but also supports macro commands, key combination setting, disabling, etc., and the functions are very comprehensive.

In daily use, I really feel that the three modes are really convenient!

At home, I still use a desktop computer more. Duga K330W mechanical keyboard can easily choose 2.4G or wired connection, which is very convenient.

Of course, the Bluetooth connection is equally convenient, and it can be easily connected to the notebook, replacing the original keyboard of the notebook, and obtaining a better text input experience.

Let me talk about the experience of using the Dujia K330W mechanical keyboard. Personally, I prefer the red axis, because it is very suitable for both home and office. The red switch of the Duga K330W mechanical keyboard has two feelings. One is to maintain the characteristics of the red switch key travel and pressure grams, while adding some neatness. When typing, the press and rebound are faster and the hand feels Excellent; secondly, the mute is quite in place, which is very suitable for office use.

In addition to being used on PCs, Bluetooth connection to tablets is also a better substitute for the original keyboard of the tablet.

In the past, when typing on a tablet, the feel of the original membrane keyboard was completely incomparable with that of a mechanical keyboard. In addition, the Duga K330W mechanical keyboard is small in size, and there is no pressure at all to carry it with the tablet when going out, which is very suitable for light office use.

The last small detail: because of its small size, I usually place the Duga K330W mechanical keyboard on the monitor stand after using it. The desktop is more refreshing, and it also adds a lot to the appearance of the desktop. It is really excellent.

Summary | Super high appearance + excellent feel, Dujia K330W mechanical keyboard is worth having

In terms of overall use, I think the Duga K330W mechanical keyboard is a very unique product. It maintains the consistent good looks of Dujia, and at the same time, it is too in place in the adjustment of the feel. Even users like me who have used a lot of red-axis mechanical keyboards can feel Dujia's intentions in optimizing the feel.

Of course, as a 61-key keyboard, the only concern is that users need some time to get used to it.

Three modes + high appearance + excellent feel, Dujia K330W mechanical keyboard is worth having!

This is a series of articles, recording the process of designing and assembling the mechanical keyboard by myself, reviewing the previous situation:

Hello everyone, I am Wuchen

. I'm here to hand in the paper

If nothing else, this may be the first in the world, combining the achievements of Filco and Logitech Union, while sitting on
three-mode
, small arrangement,
Union
, low power consumption,
Full key programmable
All-in-one mechanical keyboard

please allow me to show off

please allow me to show off

First picture:

Um? Isn't this just an ordinary minila air keyboard?

Don't worry, we can't just look at the appearance. As the saying goes, good-looking skins are the same, and interesting souls are one in a thousand. Under the seemingly ordinary appearance, there is a distinctive "core":

now that's it

now that's it

Here's a close-up, the top is the original master control of minila, and the bottom is the super enhanced version designed by me, which has been iterated to version V1.0.5

Here's a close-up, the top is the original master control of minila, and the bottom is the super enhanced version designed by me, which has been iterated to version V1.0.5

Considering the adaptation of other shells, a small board is made separately for the USB terminal

Considering the adaptation of other shells, a small board is made separately for the USB terminal

Tsk tsk, the more you look at it, the more beautiful it is, the dreamy combination of the three giants in the global keyboard industry, everyone, are you sure you don’t want to come to a set??

Detailed features:

Three-mode, wired, bluetooth, and 2.4g Union
. Among them, the wired and 2.4g modes support the use of BIOS

Support custom arrangement,
Full key programmable in all three modes

Wireless based on Logitech K375S,
Support full Unified features
(Bluetooth, 2.4g, low latency, stable, power saving)

Supports Logitech Flow,
Seamlessly and automatically switch between different devices
(It needs to be eaten with a mouse that supports Logitech Flow, I use Logitech Master 3)

Fast wake-up from hibernation
, the first key can respond (Minila original Bluetooth, it takes 2-3 seconds to wake up, and the key does not respond during the wake-up process, the experience is very bad)

The K375S native Fn key is mapped to the second-level key value, which can switch up to 3 devices through shortcut keys (no need to flip the keyboard operation)

Filco minila air original matrix PCB board, positioning board, shaft, cap,
Retains the delicate feel of the big F, tuned by a big factory, authentic

Perfect support for Filco minila air bluetooth wireless version case (battery compartment, LED indicator light, power switch, reset button, 6-position DIP switch)

Support wired version minila to wireless three-mode. In theory, except for minila, any small configuration matrix can be supported (welcome small partners in need to come and harass, maybe you can drive a wave car)

Although it was completed faster than expected, the process was not without twists and turns

After getting the first board back from Jiali Chuang, you need to solder the components on it first. Speaking of welding plates, that was also the first time a big girl got on a sedan chair. If a worker wants to do a good job, he must first sharpen his tools, and he must not be sloppy when it comes to tools, and he opened the buy, buy, buy mode:

Do you all know these?

Do you all know these?

Too little table space, peg board YYDS

Too little table space, peg board YYDS

Before actually doing it, I specially reviewed a lot of circuit board soldering tutorials. When I watched the video, I thought, well, it is quite simple, as long as you have hands. To the actual operation, I suspect that I may have a prosthetic hand

There is nothing difficult in the world. After continuous practice, it turns out that the soldering iron does not need to be hot. It turns out that the solder has specifications. It turns out that the heat gun will blow the SMD components away. ...don't ask me how I know this...

After finally soldering out the first main control board, I couldn’t wait to power on the test. If there is no accident, there is still an accident: the computer cannot recognize

Comfort yourself, the probability of success in the first board is extremely low, unless you are very talented. Let me wait for mortals to calm down and analyze what went wrong.

When I was thinking hard and couldn't find a clue, I wondered if it was a problem with the data cable. I immediately changed the data cable and plugged it into the computer. "咚咚", the computer successfully recognized

Haha, it's really a problem with the data cable. I didn't expect to design and solder the circuit board for the first time in my life.

After being excited for a long time, I still calm down. The first step of the Long March is a long way to go. The real difficulty is yet to come.

Although the position of each positioning hole, screw hole, and component is checked with a caliper, there is still an error. One of the positioning holes cannot be put in. Of course, obsessive-compulsive disorder cannot bear it. Re-measure and then build the board. It takes more than half a week to play a board, and most of the first month is spent waiting for the board. However, after playing a few versions, I found that my proficiency in schematic diagrams and pcb layout is getting higher and higher. It took more than half a month to make a version before, but now it can be done in less than a day. After the third edition, the circuit board finally fits perfectly with the shell, and the wiring and layout are also optimized

After the circuit board is OK, continue to work on the software, upgrade the system to the latest, then transplant the previous test code, correct the non-standard parts, and write the formal logic. The logic is not complicated, and with my software background, it is relatively smooth

Because the minila original matrix circuit board needs to be reused, the next step is to measure the original minila matrix first, and then make a matrix table according to the key value. Manual labor, no technical content, and it is completed quickly. Enter the matrix table into the code, burn it, insert the USB cable, and successfully recognize the keyboard, the key value is normal, and the shortcut key is normal

So far, it took three years to finally transform the Bluetooth version of the keyboard into a wired version

The reverse operation is the most deadly

The reverse operation is the most deadly

Of course it's not over yet, we have to add a heart of Youlian to it. Everything seems to be going very smoothly, and I feel that the task can be completed ahead of schedule in May, and I am ecstatic. If there is no accident, there will be another accident

Sure enough, in the process of driving the optimization, it was first found that the main control frequency was insufficient, which caused the keys to be triggered and connected by mistake; then it was found that the key trigger delay was abnormally high (up to 300ms), and the k375s could not be woken up normally after sleep

These two problems can be said to be the biggest stumbling blocks, because they are the limitations of the hardware itself. If you are not sure, you can change the hardware chip solution, overthrow all the design and start over, or the whole project will fail?

I have been groping in the dark for 2 weeks, and I have consulted the bosses in various forums and groups, and various measurements of Union matrix scan mode (after research, I found that Union is not a standard matrix scan timing, and it has been specially optimized for power saving, YYDS? ?, but this also brings more complexity to driving it, and I will have a chance to talk about it in detail later), I tried all the methods I can think of, but there is still no progress. Although I didn't want to admit it, I felt that this was the end of it, and I wanted to give up several times. However, one morning, when my eyes were sleepy, a wonderful idea suddenly popped up in my mind. Carp stood up and got out of bed, with his fingertips flying and jumping on the keyboard, compiling, burning, running, waiting quietly, one minute, five minutes , ten minutes...an hour has passed, the test passes, everything works fine. The feeling at this moment is so wonderful that I can't describe it

As of now, using this keyboard to write manuscripts,
Hole dug 3 years ago
It finally ended perfectly, dreamlike and fantastic. There are countless big and small problems solved in the process, hundreds of TODOs are full, and it is difficult, so I will not express it for the time being

Some friends may want to know how much it cost in total, so let’s list it roughly:

Second-hand minila keyboard * 2, about 800 yuan

Second-hand left shift 64 keyboard, about 200 yuan

Logitech K375S keyboard * 2, about 150 yuan

2-in-1 soldering station, about 280 yuan

Consumables such as solder paste, solder wire, tin absorber, tin absorber, etc., about 300 yuan

Components, about 200 yuan

Development board, about 200 yuan

Dupont wire and other materials, about 30 yuan

time, unknown

How much the overall cost is, you can calculate it yourself, anyway, I don’t want to calculate it (severely overspending...
）

After spending so much, what have you gained:

just fine keyboard

Several tools

Basic circuit board design and fabrication skills

Grandpa of XXX judge (yes, you in front of the screen)

Good habit of getting up at 6 o'clock

Whether the input and output are worthwhile, everyone must have their own judgment. For me, after overcoming the difficulties that I once thought were impossible, the whole city was still asleep in the early morning. When the code I wrote by myself was successfully run on the main control that I soldered by myself, the indicator lights flashed rhythmically. At that moment, what you are holding in your hand is no longer a cold circuit board, it seems to have its own life, quietly and firmly declaring your existence to the world. This kind of experience can only be understood by those who have experienced it.

In the last article, we talked about the company Jiali Chuang, so here are a few more words.

When deciding to design and manufacture hardware circuits by myself, the most widely used and powerful Altium Designer (known as AD) was the first to learn. The software operation is not bad, but it’s 2202. At the beginning, I had to draw the package by myself. Duplicate work is a waste of life, which makes people feel that AD is quite old. So he turned to the independent and free Easy EDA in China. Because it is based on the front-end architecture of the page, it has the advantage of cross-platform, but the performance is slightly affected, and the operation is not as smooth as AD. But I can't resist the fragrance of the official packaging library and user library that I have just raised my hand. It is so friendly to novices like me. It is no exaggeration to say that without the powerful packaging library of EasyEDA, my hardware design path may be discouraged at the first step

In addition to the packaging library, Easytronics has also opened up the entire process from design to board making, and the whole process is self-service. You must know that before Easytronic, you need to go back and forth with the factory to make a circuit board. I don't necessarily care about you yet.
Jia Lichuang has greatly reduced the hands-on cost of students and electronics enthusiasts. The one-stop service of Easy eda, open source platform, Easy Mall, 3D printing, and training camp is simply YYDS. Because of his existence, the knowledge and talents of many people can bloom and bear fruit at a very low cost (any small obstacle may cause a creative idea to die). Therefore, the greatness of Jiali Chuang lies not only in how much money it saves everyone for free, but also in the huge social value he brings through model innovation. I have to give it a thumbs up.

Show off some of my achievements in Jiali Chuang in the past three months:

Why did you mess up two shortcuts? Because Easy 2 times free use up - -!

Why did you mess up two shortcuts? Because Easy 2 times free use up - -!

You can't just pluck the wool, you have to feed the sheep and graze. No, I have also ordered a lot of components and tools in the Lichuang Mall.
Although not much contribution,

but wishes are good
: I hope Jiali Chuang can grow bigger and better, and continue to bring more benefits to everyone~

I would like to make a small suggestion here, hoping to adjust the free boarding strategy, reduce the number of boards each time to 3, and increase the number of free boards per month to 4 times (or only limit the total number of boards per month, unlimited boards frequency). For students and individual enthusiasts, generally 5 boards cannot be used up (3 boards are enough considering the possibility of welding damage), and many boards are wasted; for big bosses who want to mass-produce, 5 boards and 3 boards are no different . In this way, without affecting the total number of boards, it not only avoids the waste of boards, but at the same time, everyone can have more opportunities to play boards (change boards), wouldn't it be fun.
Friends who agree should like it

Now that chip prices are rising, I am also paying attention to domestic alternatives. One of the players is ESP32, which has built-in WiFi and Bluetooth. During the process, I found a place where I can get a development board for 1 yuan, and I have successfully obtained one. Friends who need it can click the link below (you can get extra points), and sign in in their software to exchange for a development board:

Click me to roll ESP32 development board

So far, the journey of "making" mechanical keyboards has come to an end

Bar?

After spending so many beautiful mornings and weekends, I finally learned the design and production of hardware circuits from scratch. It's over, and I still have more to say, so... let me know what else I can do.

Thank you for your continuous support, if you think our keyboard is okay,
Welcome to like, collect and follow
, feel free to leave a message if you have any questions

I am Wuchen, see you next time

Hello everyone~ Double Eleven is getting closer and closer, and everyone must start to study what peripherals are worth buying this year. What I want to bring to you today is the chapter on domestic peripherals, which of the A-series mechanical keyboards of Kangkang’s domestic volume king Daryou are more worth starting.

Dareu A87 is the pioneering work of Dareu A series. From the initial theme version to the follow-up three-mode version and shaft seat hot-swappable version, not only the appearance is being updated, but the internal structure is also quietly improving.

The A87 hot-swappable series currently has a total of 5 color versions, and the single-mode version is the sky version and the purple gold version that are used in the subsequent A series.

The A87 hot-swappable series continues the design of the magnetic cover and steel fixed structure of the Dareu A series. In terms of the shaft body, it is the first time to use its own customized shaft, the sky shaft and the purple gold shaft.

Starting from the hot-swappable version, Dareu A series began to add a thick silicone layer between the PCB and the metal positioning plate to remove the cavity, and this is also the beginning of the Dareu mechanical keyboard structure.

After the launch of the A87 three-mode hot-swappable version, Dareu’s follow-up new products began to roll out, each of which is directly equipped with three-mode, hot-swappable and RGB.

The A100 chooses a brand-new layout design, which reduces the size while retaining most of the conventional buttons, further improving the user experience.

The switches on the A100 are the TTC gold powder and fast silver switches that have been very good at the time until now. The configuration is full, the switches and keycaps are good, and the hot-swappable design is also favored by many players who are getting started with customization.

Dareu A84 flame red can be said to be another leap forward of Dareu A series. The stunning keycap color matching and popular arrangement, there was a rare out-of-stock situation in mass production during the first release.

Since the first launch was TTC's newly launched flame red switch, the switch body with light guide column and Q-ball feel design has also become a major selling point of this keyboard.

The surface treatment process of the base is also very amazing. At that time, even if the keyboard was disassembled and sold as a kit, it was more expensive than the official price, and the price-performance ratio in the true sense was full.

Not long after Dareu A84 was launched, Dareu launched another explosive model, that is the A98 with a gasket structure. The soft and tough material gasket structure, which is rare in mass production, has been praised by many bloggers in the circle. Since then, A98 has been equipped with machinery in 98 The keyboard has become a popular choice.

Different from many mass-produced mechanical keyboards with gasket structure at that time, Dareu A98 chose PC material positioning plate with silicone layer as the supporting inner tank, and the edge was added with silicone layer to engage the upper and lower covers, and the bottom of the PCB was also added with thick silicone support. Real de-cavitation has been achieved, the hand feel of each part is more consistent, and the soft elasticity of the gasket structure is also particularly obvious.

As for the choice of the shaft body, it is its own sky shaft V3. The light and linear feel of the sky shaft is combined with the fence-type shaft core design of the V3 version, which further improves the stability of the shaft core, and has also been used in different subsequent Dareu products.

Dareu A84pro can be said to be a relatively niche product, and it is also Dareu’s first aluminum mechanical keyboard. The audience is more enthusiasts and customized players.

In terms of appearance design, the workmanship and surface treatment of the aluminum alloy material bring people a good texture and touch, and a sound control wheel and a more distinctive RGB pickup light strip are added above the keyboard, making the appearance of the keyboard very recognizable high.

In terms of structure, of course, the gasket structure of the explosive product A98 is used. The shaft body also adopts the sky shaft V3 mentioned above. It may be the sound reverberation effect of the upper and lower covers made of metal. It is easier for Dareu A84pro to create what is called "Mahjong" on the Internet. sound". Of course, everyone has their own preferences for the sound, and it is not recommended that you judge the quality of a keyboard by the sound of the keys.

Sure enough, 87key still has a higher audience. After going around with different configurations, the A87 was finally upgraded to the Pro version, and the structure was further improved.

Due to the upgrade to the gasket structure of the A87 Pro, the design of the magnetic upper cover has also been cancelled. Moreover, the silicone layer of 87pro has also been upgraded to a fence structure, and the edge wraps the PC positioning plate while strengthening the bite of the upper and lower covers. On the whole, Dareu's improvement in structure has not stopped, and it has been improved from different angles.

Dareu A81 is a recent new product of Dareu. This time, the new product has re-adjusted the structural design and adopted a steel-free gasket structure design.

The casing and keycaps are black and transparent, and the appearance is full of value. There is no steel structure, that is, no positioning plate, the shaft body is directly welded on the PCB, the bottom layer is supported by silicone, the upper and lower covers are occluded with a non-positioning plate structure, and the soft elastic feeling of the keys is softer. It is a brand-new gasket structure mechanical keyboard experience.

After looking at so many Dareu A series mechanical keyboards, I personally feel that A81 is the most anticipated one at present. For both daily use and light customization, I personally recommend A100 and A87 Pro. I hope that after reading it, it can bring you a little inspiration for buying a mechanical keyboard~
