Teach you to make your own laptop keyboard USB lighting.One of the common situations in university dormitories is to turn off the lights at night. If there is no light, looking at the screen with a notebook and typing on the keyboard are very useless. In the long run, it is not far from the day when you put on the bottom of a wine bottle. Improving the lighting environment is the bounden responsibility of DIYer.Material preparation:


Plastic model (type L and H)4 small LED lights (3.7 volts)Current limiting resistor
USB connectorVelcroHot melt adhesive and soldering iron
Step 1: first transform the "L" plastic model. Cut two models of moderate length and paste Velcro on them respectively.Stick them together with glue, and the Velcro is opposite.Make the same model, and then stick them to a long l model (the length is equal to the length of the screen).
The effect installed on the book is shown in the figure belowStep 2: next, consider the installation of the circuit. It's time for model h to play. In order to install LED lights, we have to dig holes. The model is about 35cm. The four holes are divided into five sections. Two sections on both sides are 4cm, and the middle is divided into three equal parts, each equal part is 9cm.Put the light in.


Connecting resistorConnect a 160 Ma fuse in series to avoid short circuit.Step 3: find a suitable angle and stick the two parts with hot melt adhesive. Connect the USB connector again.
Step 4: paint the surface of the device once.Dig a hole between the USB cable and the circuit connector and let the tape pass through the fixed USB cable.Step 5: install the device on the top of the computer and try the effect. It's not bad.

After Durga brought you a K330w with extreme battery life last year, in 2022, Durga brought the latest upgraded version of this keyboard, K330w Plus, but it should have a good wireless battery life. After the model connection and beautiful appearance, what fun upgrades can Dujia bring, let me take a look.






First of all, in terms of appearance, K330w Plus (subsequently referred to as k330) has maintained the original design style in the future. The appearance and keyboard theme have not been redesigned, but still continue the previous double shell design. At the same time, the ice cream version I started with It also adds a gradient color transition style, which makes the keyboard full of personalized style. The left and right sides of the top are respectively placed with a type-c interface and a huge wireless switch, which is really convenient to use.






The k330 adopts a standard 61-key arrangement, which is small and cute, except that there is no independent arrow key, which is a small disadvantage (but the lower right corner can be directly used as an arrow key by switching the configuration). In daily use, for me personally, there is no What is the discomfort? After all, I don't use the F area much, and the number area does not put pressure on me by using the number part of the letter area.



Due to the adoption of 60% arrangement, Dujia also adopted the method of FN plus combination keys to realize the second-layer definition of various keys. The FN key that you may often use is also directly placed in the lower right corner of the keyboard, which is more convenient for you to directly operate.




The design of the bottom of the keyboard is simple and clear. Although it adopts a small arrangement design, the K330 still designs a storage compartment for the 2.4G receiver of the keyboard, so that the keyboard can be carried out without missing the receiver. At the same time, the keyboard also provides a one-stage The foot supports can be chosen by friends who like different input angles.




Dujia often likes to show his caring for keyboard players in small details. For example, Dujia’s space bar also directly adopts a circular arc design on the lower edge, so that typing will feel more comfortable when using spaces. I usually like to reverse the space on the keyboard, which reduces the operation by one step.




As for the keycaps of the K330, a set of two-color injection-molded PBT keycaps is used. The height of the keycaps adopts the height of the original factory. The surface of the keycaps is also finely frosted to make the feel more delicate. The overall workmanship, the nozzle processing is quite excellent, and the characters are also very good-looking closed-mouth fonts. At the same time, many keycaps also provide shortcut key characters engraved on the side, and the ribs in the space can also be seen. The workmanship of the keycaps is quite rigorous. Different from the blue-pink color of ice cream in the keyboard theme, the keycaps use a more low-key cool gray and cool white color, which makes the keyboard feel colder as a whole. At the same time, the cyan color matching of the space bar, ESC and enter key is also smart, which adds a lot of color to the keycap as a whole.




After removing all the keycaps of the keyboard, the silver positioning plate and the silver switch of Jiadalong come into view. One of the major upgrades of the K300w Plus this time is that the keyboard has begun to support the hot-swappable design. After removing the shaft body, it can be seen that part of the reason for the powerful battery life of the K330 is that the keyboard is of course designed without LED lighting. At the same time, it can be seen from the PCB that the keyboard supports tripod axes and pentagonal axes, and there is no space for SMD lights, so that the K330 is basically compatible with all axes on the market (not short or other abnormal axes), hot-swappable It also becomes easy to freely change the shaft body you like.



The k330’s large key still adopts the design of the satellite axis. On the one hand, it is convenient for the keycap to be better in the future. After the factory run treatment, at the same time, the feel of the satellite axis is still very stable. The feedback of the axis body is stable when it is tapped, and there is no sensuality. In terms of the shaft body, the crystal shaft series customized by Dujia and Jiadalong that I use here are also lubricated before leaving the factory. At the same time, after the tuning of Dujia, the shaft body will feel smoother. The ultra-fast trigger of 1.2mm on the silver axis makes daily typing easier.



The disassembly of the keyboard is not complicated. After all the keycaps are removed and the six screws on the positioning board are removed, directly lift up the position of the blank space. Be careful of the card position at the type-c interface in the upper left corner, and you can directly lift up the entire keyboard. Locate the board and the pcb part, but be careful at this time, the battery cable of the keyboard, and the wireless antenna are also connected to the pcb, so you need to be careful when removing it.



The positioning board and pcb of the keyboard are still fixed by screws. At the same time, between the two, the silicone pad is filled this time to optimize shock absorption and noise reduction, which reduces the vibration feedback when the shaft is struck, making typing more comfortable. .




A small amount of sound-absorbing cotton is also added to parts such as the hot-swappable shaft seat at the bottom of the k330 to reduce the vibration at the bottom of the keyboard and the feedback of the cavity sound. At the same time, the pcb also specially adds a wireless antenna interface to enhance the overall wireless reception stability of the keyboard.




There is also a specially cut black sound-absorbing cotton at the bottom of the keyboard, and it isolates the pcb of the keyboard from the battery. This large 3600mAh battery also guarantees the wireless battery life of the keyboard. It has an astonishing 240-day battery life, and the 2.4G wireless mode also has a 180-day battery life. It is not a dream to forget to charge. At the same time, the battery of the K330 keyboard can be fully charged in about 3 hours. It has a long battery life, fast recovery, and this stability Wireless, saying goodbye to wired is not a dream.




Not enough As for the structure, I don’t know if Dujia will add another upgrade in the future, such as accessing the Gasket structure that is relatively popular this year, so that the input of the touch feels softer and provides more keyboard playability.



K330w Plus continues the amazing appearance of K330w, stable three-mode wireless connection, long battery life, and the upgrade provides a more convenient hot-swap ability to replace the switch body, bringing stronger playability to the keyboard At the same time, it provides a variety of noise reduction and shock absorption optimization, which enhances the player's hand experience. If you can accept 60% of the keys, the K330w Plus is indeed a keyboard worth buying.

Hello everyone, I am Lifeisgood, the original author of "Synology NAS Unofficial Introductory Manual" from Aunt Zhang's family (If you can't remember English, just call me Lai Fujun in Chinese). In June of this year, thanks to Aunt Zhang’s love, I was lucky enough to get an LG gram 16-inch thin and light notebook computer during the public testing activity.


The new generation of LG gram is the benchmark for high-end thin and light business notebooks in 2022. It incorporates a 16-inch high-definition large screen in a slim body, is equipped with the 12th generation Intel® Core™ processor, and has passed the Intel® Evo™ platform certification , equipped with dual Thunderbolt 4 and other advanced and complete mainstream interfaces, LPDDR5 memory and NVMe Gen4 solid-state hard drive, built-in 80 Wh lithium battery, which can provide up to 20.5 hours of long battery life, and weighs as light as 1.19kg. LG gram is a powerful productivity tool that combines mobility, portability, and scalability.


LG gram 16 uses the original anti-glare 2K high-definition large screen with a screen aspect ratio of 16:10, which is very suitable for daily mobile office. After completing the evaluation, the control of this LG gram 16 was handed over to the girlfriend.



In order to sit on the sofa and watch live variety shows, I bought a laptop lifting stand; for office work, I installed printer drivers, video conferencing, and instant messaging software. But it was really time to start work, and my girlfriend said that the laptop was placed on the lifting stand, which made it inconvenient to type and not easy to use.



The ancients said that a good horse deserves a good saddle; passers-by say that poor students have a lot of stationery. Then build a mobile productivity office desktop around this ultra-thin and light notebook with a long battery life and match it with powerful peripheral equipment.


The OG80 Wormhole is the main mechanical keyboard I use every day. It has a three-mode connection, the key shaft supports hot swapping, and the 83-key layout saves desktop space. The percussion sound of the green axis is crisp and the feedback is favorable, which is suitable for my crazy typing every day.


The current situation is that both of them work at home. In order to distinguish, this time I chose the red OG80 happy vending machine.



The shaft body chooses the fast silver shaft. My girlfriend likes to play games, but doesn’t type much at work, so this high-precision, fast trigger and rebound switch is more suitable for her. As for the RGB backlight, it is a must.




This OG80 is named Happy Vending Machine, with happy and bright red and white as the main colors.



80 layout, three-mode connection, mechanical shaft body, MAC adaptation, full-key no punching, hot-swappable shaft, the main selling points and parameters are clearly conveyed on the back of the girdle.



The bright berry red, coupled with free pure white keycaps, is like dotted with red marks on the white snow, accompanied by the tapping rhythm, it will make you full of energy in an instant.



The smiley face element leads, the ESC key ranks first, and the keycap pattern integrates the theme of happiness and motivation.



The round and lively smiling face pattern and the undulating lines imply the ups and downs of life are smooth sailing.



A number of happy-themed red keycaps are presented as a thoughtful gift, allowing you to DIY as you like and switch your desktop style at any time.



At the same time, a MAC supplementary key (white keycap in the picture) is also presented.


The OG80 Wormhole mechanical keyboard supports wired, Bluetooth, and wireless three-mode connections.



On the right side of the smiley ESC button, there is actually a vertical LED indicator light, which will indicate different connection modes and working states in blue, pink, purple, fast flashing and slow flashing. The wireless receiver is actually hidden and stored.



The red magnetic cover in the upper left corner is opened, and the USB wireless receiver is stored inside to prevent loss and easy to carry.



This is a 2.4G wireless receiver, or according to the official switching sequence, it is called connection 4 (because it is switched with the Fn+4 shortcut key).



Bluetooth supports simultaneous connection of 3 devices (use Fn+1, 2, 3 to switch).


Therefore, through 2.4G wireless/Bluetooth 5.1 technology, 4 devices can be connected wirelessly at the same time. The current device can be switched flexibly and quickly with Fn+1, 2, 3, and 4.


For example, the wireless receiver is plugged into a desktop computer or an e-sports notebook. After all, playing games requires extremely low latency. Then laptops, tablets, and mobile phones use Bluetooth to connect. With a wireless/Bluetooth multi-mode mouse, you can control 4 devices with one keyboard.



The wired/wireless toggle switch at the bottom can also be used as a power switch. While connected by cable, it is also charging the keyboard.




The top F keypad is tilted at a larger angle, which visually highlights the personality and is more friendly to zero-gravity users: since the F keypad faces the user at a large angle, when you lie flat on the ergonomic chair, lower it slightly You can easily distinguish the buttons in the F area without looking up, so you don't have to get up and check.



When purchasing the OG80, I deliberately chose the RGB backlight model (there is also a matte version). When the keyboard is in wireless connection mode, you can press Fn+Del to turn on the backlight. OG80 happy vending machine supports 16 million color dynamic light effects, uniform color, many modes and gorgeous effects.



The wireless receiver is very small, and I am afraid that I may accidentally lose it. The storage card slot here on the OG80 has a magnetic cover, which is convenient for storage and will not be lost.



The mainstream Type-C interface is used on the back, and wired connection and charging and replenishing blood can be done at the same time.



No matter how fast your hands are, you can achieve no conflict with all keys and respond quickly at the same time.



The keyboard and the Type-C cable are designed separately and stored separately. When you go out and need emergency charging, you can also share a cable with your mobile phone.



The OG80 happy vending machine uses durable PBT material keycaps, which are delicate in touch, not easy to oil, and have a good texture.




OG80 happy vending machine only has a little regret, that is, the keycap is not transparent. When the ambient light is dim at night, it is not very helpful for distinguishing keys. The flaws are not hidden, I plan to buy a few custom-made light-transmitting keycaps to solve it, and it doesn’t take much. It is enough to replace the most commonly used F9, Fn and equal keys.



The OG80 happy vending machine is quite high in terms of playability and customization.



Not only can the keycaps be customized and replaced, but the OG80 happy vending machine also uses hot-swappable switches that are unique to high-end mechanical keyboards.



The standard two-in-one tool, one end of the steel wire is a key puller, which is convenient for us to remove the keycaps, and can be cleaned or replaced with custom keycaps.



Users can disassemble and replace each shaft at will. Turn the 2-in-1 tool upside down, with the shaft puller on the other end.




Poor students have a lot of stationery, and they have to copy homework from the list. Unknowingly, this LG gram 16 has been equipped with a lot of good digital peripherals.


In order to meet the needs of daily remote meetings, efficient office, professional drawing, etc., I want to buy a portable display with the same size, resolution and aspect ratio as LG gram 16. After reading the reviews and breaking the news at Aunt Zhang’s house, I finally chose EHOMEWEI Q3 (一港微), which uses the same screen as LG Gram +View, and more importantly, it adds a high-precision handwriting function, which can meet the requirements of meeting annotations. Higher requirements for records, calligraphy and painting, design and drawing, etc.


Based on years of habits, I pay the most attention to two points when choosing a wireless mouse: one is that the battery life should be long, and the other is that there are two function keys for forward/backward (this can be doubled when managing files and browsing the web). Improve efficiency).



Supports simultaneous connection of two devices (such as notebooks, tablets, desktops, mobile phones, etc.). How to switch? Pay attention to the small button behind the scroll wheel. Short press is to switch between wireless and Bluetooth, and long press for 3 seconds is to switch between mac OS and Windows operating system.



That is to say, it is possible to switch between two hosts with one key, which is convenient for controlling two computers at the same time. Overall, this is a very cost-effective dual-mode wireless mouse.


Compared with conventional notebook stands, this stand is made of aluminum alloy and looks very good. And the function of rotation and lifting is added, which is very practical.


I bought a new LG gram machine and cherished it. The original factory gave me a transparent keyboard protective film. I also need a laptop bag for carrying and protecting it when I go out.


I chose this portable 16-inch bag. Because notebooks are ultra-thin and light, from the perspective of lightness and portability, the notebook bag is also selected to be thin and light.


Looking at it this way, it is found that a notebook computer needs a lot of peripheral equipment. In the next article, peripherals such as active noise-cancelling headphones and Bluetooth speakers will be released, so stay tuned.

To be honest, I never thought that I would become more and more out of control on the keyboard. Although I have some preference for things made of metal because of my background in mechanics, and I know that different "skins" have little to do with the feel of the keyboard, but I still have the same "collection addiction" as I played "Dynasty Warriors" before.


This time I bought the IQUNIX F97-Tuya Diary model keyboard from the "Aluminum Factory".



The box is very heavy, and it is heavy in the hand. The girdle pattern this time is very cute, and it even has a Chinese New Year feeling.




I really like the feel of the TTC-ACE axis now. As for RGB, it should be essential.



The accessories inside are still the classic configuration of the aluminum factory, keyboard protective cover, keycaps for MAC, wireless USB adapter, key puller, shaft puller, cleaning brush and data cable.



The graffiti aluminum alloy frame, in addition to white, is also available in red and black, all of which are very beautiful. But personally I still prefer white.



At the bottom of the keyboard, the LOGO of F97 is very beautiful, echoing the keycap pattern.



The keyboard frame is still a thick aluminum plate, which is assembled with bolts after cutting, grinding, chamfering, punching and tapping. It is high-end and stackable enough, and the cost is much higher than that of sheet metal stamping and stretching.



The big key is the ancestral balance bar design, and the factory grease is fully filled, smooth and not astringent. The TTC-ACE axis is composed of a transparent shell and different shades of green. Feel the optical axis body, and you can play with it for a while.



The small keyboard area is designed without gaps, taking into account the functionality of the 104 arrangement and the small size advantage of the 87 arrangement, it can be said to be very versatile. It supports the separation of keys and lines, 96% layout, and does not pick up space. On the basis of retaining the small keyboard, there is a lot of space for the mouse position on the right. It is very comfortable to play games and draw pictures.



The appearance and texture of F97 can be said to have few rivals, and what is even more rare is that such appearance and texture are based on ensuring the full functionality of the keyboard.



The keyboard adopts a three-mode design, wired, wireless, and Bluetooth three connection methods, which can meet almost all my needs. Computers, notebooks, desktops, and even mobile phones at home can be extended and used.



Turn on the backlight, it is very comfortable to use at night, and you can adjust various lighting effects and customize the lighting.







Put it on the computer desk, the unexpected harmony, the color matching and the workmanship of real materials, I really can't get enough of it.



The trigger force of the TTC ACE shaft body is 53g, the bottom touch is 60g, the trigger key travel is 2mm, and the total key travel is 4mm. In terms of game experience, the keyboard has a refreshing feel without muddling, and the operation is very clear.



In terms of input experience, F97 adopts TTC-ACE shaft body, coupled with the unique design of large keys, the hand feeling is naturally guaranteed. The big keys don't feel stiff or muddy. The hand feel is very balanced, comfortable, and the feedback is good. I feel that the ACE switch is a super-enhanced version of the cherry black switch. It is also very suitable for long-term coding, and the fingers are not easy to fatigue. After getting used to the key arrangement for a period of time, there will be basically no accidental touches. For me, the main reason is that the F97 has a small keyboard and a small enter key, and the input efficiency is very high, and it can be adapted to games and brick-moving work.



In general, the IQUNIX F97 graffiti-themed keyboard is still the consistent high-level workmanship and material performance of the aluminum factory. Personally, I also like the feel of the TTC-ACE switch.



The layout of 100 keys with a small keyboard and the connection method of wireless three modes have achieved a certain balance in size and function, unlocking the adaptability of some special requirements of the scene, suitable for codeword games. The built-in 4000mAh battery capacity of the keyboard also ensures that it can have a long enough battery life even if the RGB lighting effect is turned on, and it can be used as a "productivity tool".

As a worker, the keyboard is the guarantee of my strong productivity in the office, and the most important thing for Sister Ting about the keyboard is the appearance. Many mechanical keyboards are full of strong e-sports style. As a girl, I still hope to find a keyboard with good looks and a sense of design. Recently, Sister Ting finally found a Lofree Luofei Xinghe Xiaoqiao 100-key mechanical keyboard designed by Peking University's cutting-edge artist Tian Danlu.



In fact, the products of Luofei’s family are all very good-looking, but this Lofree Luofei Xinghe Xiaoqiao is so beautiful that Sister Ting fell in love with it at a glance. The outer packaging is an oil painting that Tian Danlu is very good at, and it blends well with the color of the keyboard. The whole packaging is very delicate, and people can't help but want to see how brilliant the keyboard is.



When you open the package, you can see the main body of the keyboard, which is amazing at first glance. The color matching of the keyboard is the same as that of the outer packaging, and a large number of purple and yellow are used. Through the gradient design, there is a good transition between the two colors without being obtrusive at all. The purple is the deep purple of space, and the yellow is the gorgeous yellow of the galaxy. It really deserves the theme of "Galaxy". Sister Ting was fascinated when she first saw it, as if seeing the bright galaxy in the deep night sky, she felt extremely comfortable.



There are all accessories, manual, Type-C data cable, battery, and a card, quite complete.


The size of the Lofree Galaxy Xiaoqiao keyboard is 367mm×129mm×54.5mm. It adopts a simplified layout of 100 keys, which is more concise than the standard 108 keys, allowing more space to be used on the desktop. Compared with 87 keys or fewer keys, it also retains the numeric keypad area, which is more convenient to use. Sister Ting’s last keyboard has 87 keys, and it is very painful whenever she needs to input numbers. Lofree Luofei Xinghe Xiaoqiao has ensured Sister Ting’s work efficiency very well.



Lofree Luofei Xinghe Xiaoqiao has the logo of Lofree family printed on the lower right corner from the front, which is simple and elegant. The side is an upturned arc, which is where the name [Xiaoqiao] comes from. This radian is an ergonomic design, and Sister Ting will not feel tired on her wrist after a day of work.



The back design of the Lofree Xinghe Xiaoqiao keyboard is very ingenious, without using the traditional adjustable bracket. Instead, it adopts a circular strip design, and it is designed as the battery storage space and the 2.4G receiver storage area, making full use of the space, and the design of the 2.4G receiver storage is simply for people like Sister Ting. A lifesaver, never worry about losing the receiver again.



Lofree has 3 connection modes. On the side of the keyboard is a knob for adjusting the connection mode. You only need to turn it lightly to select the connection mode of the keyboard. The indicator of the knob can also flash according to the power.




There is a Type-C interface on the top, when the Type-C data cable is connected, the wired mode can be used. In addition, the Bluetooth mode can be connected to 3 devices at the same time, and can be switched through the combination key, which is convenient and fast.



In terms of battery life, Lofree Xinghe Xiaoqiao cannot be charged, and the 3 AAA batteries can be used for a month without any pressure. In addition, the keyboard has automatic sleep technology, which automatically sleeps when it is not working, making the battery life longer. Even if there is no power, plug in the Type-C data cable and it will become a wired mode in seconds, without any need for battery life pressure.



As a mechanical keyboard, Sister Ting pays more attention to the axis body than the appearance. Lofree Xinghe Xiaoqiao adopts the G red Pro shaft body, which feels quite silky, and the feedback is moderate and effortless. More importantly, the keyboard tapping sound is not loud. Sister Ting no longer has to worry about affecting others in the office.



Moreover, the keyboard supports hot-swappable full-key shaft body. If you don’t like the soft and waxy feel or like loud percussion, you can replace the shaft body and match it arbitrarily to meet the needs of DIY players.




Lofree Luofei Xinghe Xiaoqiao uses PBT sublimation keycaps, the pattern is clear and colorful, and the characters on the keyboard will not be worn off after long-term use. Sister Ting used it for a week, and there is no trace left on the keycaps. Grease. The corners of the keycaps are also different from other keyboards, and the rounded design is both good-looking and not harsh on the hand.



Overall, Lofree Xinghe Xiaoqiao is highly recommended. With its super high appearance and soft percussion sound, it is very suitable for girls to use in the office. I believe the probability of being linked is quite high. PBT sublimation keycaps are comfortable and durable, and all keys are hot-swappable. Friends who like DIY don’t have to worry. Lofree Xinghe Xiaoqiao is a 100-yuan product, and its appearance and experience are not inferior to the 1000-yuan products on the market.
