A conventional keyboard has, for instance, only one key and pitch for C and D, but an enharmonic keyboard would have two different keys and pitches for these notes. Traditionally, such keyboards use black split keys to express both notes, but diatonic white keys may also be split.

This plastic plate may also require a prying tool to pop up. Once that's done, there's a ribbon flex cable under the keyboard that needs to be carefully removed. Once that's out, you can take the keyboard and shake it over the sink. The operation requires no more than a few make-shift tools and a screw driver to do, and takes about 10 minutes. I do not know your particular laptop, but that should give you some clue about where to start. I linked a video to illustrate what I mean, and I hope it gives you a good step about where to start.
Qué marca de auriculares deportivos inalámbricos es buena y las diez mejores marcas de auriculares deportivos inalámbricos
Qué marca de auriculares deportivos inalámbricos es buena y las diez mejores marcas de auriculares deportivos inalámbricos
Comprar unos auriculares deportivos es algo muy aprendido. He cambiado más de una docena de auriculares deportivos, de 100 yuanes a 1000 yuanes, a diferentes precios y tipos. Diferentes auriculares deportivos tienen diferentes características. Al comprar auriculares deportivos, debe elegir de acuerdo con su propio tipo de deportes. Hay cuatro tipos de auriculares deportivos: inalámbricos en el oído, gancho para la oreja inalámbrico, gancho para la oreja con cable y orejeras. En este caso, prefiero usar el gancho inalámbrico para la oreja como auriculares deportivos y de fitness. Aquí hay algunos auriculares deportivos y de acondicionamiento físico populares en el mercado, con la esperanza de ayudarlo. Top1, auricular Bluetooth de conducción ósea South Carolina runner pro2 Precio de venta oficial: 1398 La conducción ósea es un ingenioso trabajo desarrollado por Nanka en la industria de la conducción ósea durante 10 años, por lo que está equipado con la tecnología más avanzada en mano de obra y configuración. Este runnerpro2 es el primer auricular de conducción ósea que utiliza tecnología de directividad de choque total. Con el apoyo de esta tecnología, puede resolver eficazmente la pérdida de calidad del sonido causada por el aumento del volumen de los auriculares tradicionales de conducción ósea. Aunque la conducción ósea no tiene inmersión en el oído, ¡la pérdida de calidad del sonido también debe minimizarse! Cuando usa este auricular de conducción ósea, está hecho del mismo material de titanio que la ingeniería aeroespacial, que aún puede adaptarse a la piel y mantener la comodidad incluso en escenas deportivas violentas. Esto también es compatible con la memoria del fuselaje. Se ha actualizado de 8 g de la generación anterior a 16 g. La memoria del fuselaje tiene memoria de reproducción. Al jugar localmente, seguirá jugando en la última posición. Incluso las novelas de media hora de diafonía no tienen miedo a la interrupción. En términos de operación portátil, también admite conexión rápida NFC. Los teléfonos Android que admiten NFC pueden realizar un emparejamiento rápido solo al tocarlos. Top2, auriculares deportivos de conducción ósea Shaoyin aeropex as800 Precio de venta oficial: 1298 Auriculares Bluetooth deportivos de conducción ósea. Este auricular de conducción ósea también es relativamente de gama alta. Es compatible con ipx7 a prueba de agua y adopta carga de succión magnética. En los contactos de la interfaz de succión magnética, se adopta un recubrimiento de rodio con un mejor rendimiento a prueba de agua para evitar la entrada de agua. Incluso si la entrada de agua tiene la función de "monitoreo de residuos líquidos", cuando hay manchas de agua que no están secas, se activará el sonido de advertencia del auricular y la luz indicadora. No hay abertura para el altavoz en la superficie de la unidad generadora de sonido del auricular. El sonido se genera a través de la vibración de la propia concha elíptica, que es como un tambor vibrando. El área de la unidad generadora de sonido no es tan grande como la de Nanka, por lo que existe una falta de comodidad. Si tu cara no es muy gorda, tiene poco impacto. Precio de venta oficial: 969 El rendimiento de este auricular es muy bueno en todos los aspectos, especialmente en apariencia y comodidad de uso. El estilo TWS tiene una calidad de sonido pura de baja frecuencia y un excelente efecto de sonido, que está sesgado hacia el estilo de bajo pesado de metal. La calidad del sonido y el ritmo de escuchar música son muy buenos. La caja de carga tiene una mano de obra exquisita, todo el cuerpo de metal, una textura fuerte, una sensación de mano súper buena y una atmósfera de alta gama. El auricular es pequeño y exquisito, con forma única y textura de metal. El estilo general es natural con la caja de carga. TOP4, auriculares Bluetooth deportivos Sony wf-xb700 Precio de venta oficial: 699 Los auriculares Bluetooth de la serie deportiva de Sony, como muchos productos similares, Sony wf-xb700 también están equipados con una cabina de carga exclusiva. La vida útil de los auriculares es de aproximadamente 9 horas. Con la cabina de carga, puede admitir la reproducción de música durante aproximadamente 18 horas. Sony wf-xb700 adopta un diseño de tres etapas para garantizar la estabilidad de uso a través de la estructura fija de tres puntos de la cavidad del auricular. Este diseño estructural significa que es difícil hacer que el auricular sea lo suficientemente pequeño y usarlo de manera relativamente estable. Se puede controlar fácilmente para correr o hacer ejercicio todos los días. Top5, auriculares deportivos de conducción ósea Nank Nanka CC II Precio de venta oficial: 299 Nank Nanka, como la primera marca en la industria de auriculares de conducción ósea, ha sido un producto de moda en los últimos dos años. Desde el lanzamiento del primer corredor CC de conducción ósea de grado de consumidor de Nank Nanka, su rendimiento de costo ultra alto ha hecho que los auriculares de conducción ósea lleguen al mercado masivo, lo que no solo hace que más personas se den cuenta de la belleza de los auriculares de conducción ósea, sino que también afecta profundamente el desarrollo tendencia de la industria de auriculares de hoy. Esta segunda generación también continúa el concepto de la generación anterior, conserva la carga de succión magnética solo disponible en el modelo insignia, también tiene un rendimiento de costo ultra alto y se ha mejorado mucho en la configuración. Se centra en correr, andar en bicicleta y otros grupos de usuarios sin oído. Fqj
Wireless Mouse Program for Damn Small Linux?
Wireless Mouse Program for Damn Small Linux?
Slax has a contemporary kernel to be able to support most wireless playing cards that Linux supports. It is a reside cd however there's an option to put in it to the tough pressure. The major cd is most effective 192 MB and comes with KDE.1. Can I Piggyback a Wireless N router off of a Wireless G router with an ethernet cable?no the reason it is the same is that most people will never see a difference in speed because most people only brows the web and that is not much traffic try using a video streaming site2. How .do you tell if your computer has a wireless card? And what is a wireless card?You mention that you have cable internet. ( or DSL ) The cable company added a cable modem, that provides an Ethernet internet network connection. Ethernet, is a standard network type of connection, and most computers have an ethernet card installed, or on the motherboard. The connector for this looks like a phone jack, except wider. So you can plug one end of the cable modem directly into the back of a PC, and have internet access. If you want to share the internet connection, you need to buy a router. They are cheap, about $35 to $50, and will expand your one Ethernet connection to 4 or more. You can also get a wireless router as well. This is the same, as the other router, but also has transmitting capability, so other PCs nearby 150ft or so, can also receive the signal without having to run the Ethernet cable. However, even if you only have one PC, you should get a router, because this adds an extra layer of security to your internet connection. See the description below. Some laptops have the wireless hardware installed inside, or you can add the wireless card in one of the PCMCIA slots on the side. PCs probably dont have wireless built in, but can be added by installing a card inside the PC, with an antenna which attaches externally. These cards also only cost $15 to $40. Go to the store and get D-Link. Its an ok brand. Everyone has their favorites. Just be sure to change the admin userid, and password as listed below. ( they all ship with the same password ; ( Ethernet: 1. Ethernet, from your laptop/pc to a local broadband router. ( adding a router, or wireless router to your home broadband connection is the best security measure you can take for your money, just be sure to re-set the admin userid and password, and enable encryption on wireless routers) If you dont have an Ethernet port on your laptop, you can get a PCMCIA add on card, or better, one that plugs into a USB port. Cost $15 to $20 2. Wireless broadband "wifi", need a wireless card(some are built in to laptops $15 to $35). Can connect to any local hot spot ( home wifi, unsecured neighbor, Cafe, bookstore etc ). 1. Ethernet, Most laptops have a built in ethernet port, which looks like a phone jack but is wider. This can be plugged directly into a router if the house has DSL/CABLE router to the internet. If the router is already working, then just plug in, then poof you are connected. 2. Wi-Fi: Wireless PCMCIA card, This is a small thick credit card sized interface that can be plugged into the side of your Laptop in a PCMCIA slot. ( usually two slots for this type of card). There are several different types. The common wireless PCMCIA card supporting various wireless 802.11x protocols is used to connect to local hot spots. A hot spot, is a location where wireless network connection is available, such as homes with wifi(your wireless router), some coffee shops, hospitols, book stores, drug stores etc. Usually the signal is only good for a about a hundred and fifty feet to your laptop or PC. Wifi: Many people have paid for for DSL(internet) or CABLE TV(internet), connected to a DSL or CABLE modem. The MODEMs are available with standard Ethernet ports, and many also have wireless 802.11x capability. The broad band internet service costs about $35/mo for DSL and $45/mo for cable. It is called "broad band"(wide bandwidth), because of the wide frequency spectrum available. The wider the frequency spectrum available, the more data you can send. Wi-Fi: short range, a few hundered feet or less. Many standards, but most problems have been resolved. It is widely used, and low cost. Widely available at low cost from any PC store. A Security Note: If you use a wireless connection to connect to an unsecured wireless network ( no password required), then anyone can use software "packet sniffer" to monitor and record all or your transmissions. This can be used to quickly hack your laptop and have full access to it, including installing hack software so it can be accessed at a later time ( when ever you are online, anywhere), or quickly download your /mydocuments folder contents etc. It is unlikely that you would be hacked in this way, but is possible. Get all of the updates for your operating system, and install the latest software for (if you use them) chat clients etc. ). Here is a list of other things you can do to save you some grief. 1A Everyone needs to clear their cache . . . . 2A Also checking your XP IE security settings. . . . . 3A Download software to scan and remove advertising, spyware, viruses, key-stroke loggers etc. 4A A router is the best security investment you can make for your dollar, if you are going to get broadband at your home. Clearing the cache and limiting its size is good maintenance. Scanning for spyware may also turn up some problems. Block hacker sites through the security control dialog box. Follow the instructions below to install and use Spybot 1.5 Browser problems are often caused by problems with the cache. 1A First clear your cache. close all IE browser windows, then open only one, and from the menu, select: Tools, Internet Options, in the pop up dialog box, select: Delete Cookies, OK, Note:( if you have IE7 the menu will look slightly different, just click Delete, then go through each of the menus to delete Files, and Cookies. You might also want to delete the other things as well such as History, Form data and saved Passwords). Then in the same dialog box: click Delete Files, and check the box that says " delete all offline content", OK Your hard disk will spin for a bit ( 20 to 40 sec) depending on the size of your cache. Dont worry about that deleting files message, it is just old web pages you visited, nothing worth saving. Go back to the same dialog box, and select: Settings, On the dialog box for this, change the amout of disk space to use to 30MB. Somtimes, this value is set way too high. Also on this dialog box be sure that the check box for: Check for newer versions of stored pages, Automatically or Every visit to the page. This setting can also solve a lot of web page access problems. 2A Go to Tools, Internet Options, Security, The slider for "Internet" should be set to Medium. click the Trusted Sites icon, there probably will not be anything in there. If you find a strange site you dont know, delete it. Only your trusted bank site, or place you know for sure should be in there. Then click on Restricted Sites. The slider should be set to high, and it should be filled with restricted sites populated by your security program. If it is empty, you can download spybot, 3A Spybot 1.5 download updates, select all available updates, download updates, and click imunize, it will show you how may bad products can be blocked, . . . Great, but you need to click imunize "again" at the top. This will fill that restricted sites box so you dont go to a hacker site. Then scan your computer for problems. It will usually find cookies and call them harmful, but it can also turnup key stroke loggers, and other nasty things, and it is free ! Reboot your computer when finished. Get Spybot - Search & Destroy 1.5, it works great, and is free. 4A Get a router, they are cheap, and provide the most protection for the dollar. You can easily pickup a router, or wireless router for $20 to $40. Your computer ( depending on operating system), can have thousands of ports that are accessible through your internet connection. Hackers, simply unleash software to scan each port address looking for a common response. When a response is detected, each important port on your computer is scanned for known vulnerabilities. Your PC may also be advertising your location, which should also be prevented. A router adds an extra layer of addressing to your computer. Adding a router makes your PC invisible unless the correct address information is provided. For example, a burglar can rob your house. But if he cant see your house, he cant see it to rob it. Windows XP SR2 comes with a software firewall, but a router is a hardware firewall. All traffic must originate from behind the firewall/router out to your selected web site, then returned thought the same path. A hacker trying a cold scan, wont see your PC, or ports because they are only one address. This can be gotten around, but will stop the vast majority of web worms, and amateurs. After you get your router, change the default user ID and password. Most routers ship with default admin passwords, and hackers know this. Change the default password, so you cant get your router settings changed in the dead of night. For wireless routers, setup encryption so you are not a open hot spot for every Tom Dick and Harry to use your internet connection to download bad things in your name. May the force be with you....3. is the verizon wireless mobile hotspot unlimited?Get a 4G adapter instead. the price is almost the same i used to use my iphone to tethering out internet. however the speed is really slow. i believe it is my iphone can not handle all those data. I now use a 4G USB mobile broadband adapter that use the same mobile signal and i got at least double of the speed
What Do You Know About TWS Bluetooth Headset
What Do You Know About TWS Bluetooth Headset
What is the hottest 3C product in 2019? It belongs to TWS Bluetooth headset. With the development of science and technology, Bluetooth headset has become a trend for voice communication. Its compact, low-cost and convenient operation makes TWS Bluetooth headset more and more popular. Kinghelm (www.bds666. Com) has developed and produced small-size ceramic chip antennas kh2012, kh3216, kh5220 and other models in cooperation with many TWS schemes, such as Qualcomm (CSR), BES, airoha, Realtek, etc., which can directly replace Murata, TDK, Roma Rohm Taiwan Wancheng, Yongye, ACX, Huake and other brands.Golden beacon kinghelm product ceramic chip antenna kh5220-a56TWS features: TWS Bluetooth headset does not need wired connection, which gets rid of the shackles of traditional headset wired connection; The left and right headphones form a stereo system through Bluetooth, and listening to songs, talking and wearing have been improved. Perfect sound experience can be realized: ear wearing voice, video call, music enjoyment, mountain climbing and running, safe driving, etc. The wifi antenna, antenna adapter line and GPS Beidou antenna of kinghelm are well done. Ceramic chip antenna products are not only applied to TWS Bluetooth headset products. It can be extended to all audio fields (TWS speakers, TWS intelligent wearable products, etc.), and the innovation or seizing market opportunities in each category is enough to make you stand out in the market!Disadvantages of TWS at this stage: battery life is the top of all problems. According to statistics, the battery capacity of a single ear is between 25-60mah, and the maximum battery life is no more than 3 hours. Of course, I believe that the follow-up one will be better. The previous one is a breakthrough in battery technology.Golden beacon kinghelm product ceramic antenna kh2012-a20The second is the bottleneck of wireless transmission distance. TWS earphones are different, because TWS earphones rely on Bluetooth technology to realize wireless communication. In the actual use process, complex environment, circuit itself, RF interference and many other problems limit their use distance; According to the measured data, at present, the mainstream use range in the market is 10m, and the farthest is only 15m. At this stage, according to the domestic application scenarios, it is obviously unable to meet the user experience needs. Who can solve the problem of transmission distance means that he has an absolute advantage in this industry!Golden beacon kinghelm product ceramic antenna kh6010-a54In addition to the high popularity of Beidou antenna, GPS antenna and antenna connecting wire in the industry, the newly developed ceramic chip antenna has the advantages of high temperature resistance, low loss, stable quality and small volume, and can be used together with Hall components sl1613 and sl1615, MOS tubes sl2301 and sl2302 of Sacco micro slkor (www.slkormicro. Com), It is very popular in the market.
Hacer diagrama del circuito de conducción de motor escalonado
Hacer diagrama del circuito de conducción de motor escalonado
Hace unos días, terminé mi tarea de vacaciones de invierno. No tuve nada que hacer estos días. Vi el motor paso a paso anoche y luego estudié el principio de media noche Hoy, encontré un motor paso a paso de 35mm en mi caja de prueba de MCU, y luego encontré el diagrama de circuito del circuito de conducción en los materiales de soporte, como se muestra en la figura Déjame decirte el principio (solo como referencia): primero, la interfaz J18 se agrega al puerto IO del microordenador de un solo chip, y el 1234 conectado al motor paso a paso J19 son a, A1, B y B1 del motor paso a paso Primero, 8550 está en un nivel bajo. Si el nivel de 1 de J18 es 0, entonces el tríodo V8 está en. Después de que V8 esté en, el nivel de 1 pin de J19 es 1 Al mismo tiempo, la corriente enciende el triodo V15 a R49. De acuerdo con el diagrama del circuito, los 2 pines de J19 están conectados al colector de V15, y los 2 pines y 1 pines de J19 están conectados Un grupo de bobinas. Los Pasos 3 y 4 son un grupo de bobinas. Ahora el nivel de pin 1 es 1. La corriente fluye a través de un grupo de bobinas desde el pin 2 y fluye hacia el polo negativo a través del triodo V15. Es decir, los triodos V8 y V15 son un grupo, V7 y V16 son un grupo, V10 y V17 son un grupo, y V9 y v18 son un grupo, por lo que los dos triodos comparten La misma corriente puede hacer que el circuito sea más estable Este es el principio de funcionamiento. Otros grupos de triodos son iguales. No sé para qué se usan R47 y R51, si alguien sabe Solo dilo, te lo agradeceré. Lo que dije puede que no sea muy bueno. Puede rociar mucho Baidu según el principio del motor paso a paso, así que no lo presentaré El siguiente es el proceso de producción; Lo que necesitamos son estos triodos 8550 y 8050, resistencia (no se encuentra 1K), excepto que R47 y R51 usan 1,3 k, otros usan 820, aguja de fila, placa de orificio y un soldador Luego instale las piezas en el tablero del agujero de acuerdo con el diagrama del circuito El otro lado Cableado Si no hay suficiente espacio, corte la almohadilla por la mitad y luego suelda el cable Algunos lugares no se pueden conectar, así que use jerséis, como este: Hacer productos terminados El otro lado El motor utilizado es un motor paso a paso de cuatro cables de dos fases Como se muestra en la figura Lo anterior es solo mi propia experiencia. Si hay algún error, señalarlos abajo El programa es el siguiente (ABC en el programa está conectado a una luz para juzgar si el programa se está ejecutando) // Este programa es un controlador de motor paso a paso de cuatro fases de dos hilos # Incluya // *** Definición ******************************* Sbit A0 = P1 ^ 7; Sbit A1 = P1 ^ 6; Sbit B0 = P1 ^ 5; Sbit B1 = P1 ^ 4; Sbit Abc = P1 ^ 0; // *** Ancho de pulso *************************** Unsigned int = 375; // *** Control de velocidad ***************************** Char sin firmar s = 2; /cambiar el valor de s para cambiar la velocidad.

What Is the Rationale for the Number Lock Key on a Computer Keyboard?
What Is the Rationale for the Number Lock Key on a Computer Keyboard?
If you look closely at the numeric keypad, you will see there are also cursor positioning labels (Home, Page Up, Up Arrow, etc.) Way back in the '80's, the keyboard did not have the cursor keypads that now lie between the typewriter keypad and the numeric, and the numeric doubled as the cursor keypad. The NumLock key was the way to signal the computer which labels on the numeric keypad you were intending to use -- Numeric or Cursor. Why is it still around? Tradition! Hope that helps.1. Laptop without number lock/alt codes?you should have a key on your keyboard called num lock. press it and the letters on your keyboard become numbers. They should be labeled with small numbers but if they are not: J=1 K=2 L=3 U=4 I=5 O=6 &=8 (=9 )=0 On a laptop the same function is performed using the function key Fn pressed at the same time as the previous keys. Check your owners manual for confirmation2. Where is the Number Lock key on the Dell Inspiron N4110 Laptop?ankit, Unfortunately, the numlock and scroll lock keys are not present in the Inspiron N4110 / N4120 / 14R systems. Thank You, Dell-Jesse L Dell Social Media and Communities3. I dont have a number lock on my laptop?Hold Fn key, Press F11. Voila!!4. What is the purpose of the Number Lock button on computer keyboards?It changes the values returned by the num pad. It is very useful for rapidly scanning through text with the num lock disabled5. How do you turn the number lock on and off a Toshiba laptop?If you can not find the numlock key on your keyboard - which if you have not already you probably wo not , since most laptop keyboards are so basic they do not have one - you can always use your onscreen keyboard. To access your on-screen keyboard, just go to Start > All Programs > Accessories > Accessibility > On-Screen Keyboard. See if you can then find the 'nlk' key.6. The number lock on my Samsonite Suitcase is playing foul. Is there any mechanism to unlock it?I do not know of a mechanism, but a tool that might work is a jackhammer!7. How do I get the Number lock key to be on during startup?You will probably have to go into the BIOS settings to get the Num Lock to stay on. If you are not familiar with doing this you should ask a knowledgeable friend, since BIOS settings could get a little tricky. Good Luck!8. Where is my number lock key on my keyboard?It will say "Num Lock"9. How do you change a 3 number lock combination?try this one i hope it help10. How do you turn off number lock?Have you tried the numbers lock key? That is usually the first place to start11. I forgot the number for number lock on my Aristocrat Suitcase. How should I open it?If it's brand new, it's probably set for 000, 000. You are supposed to personalize it yourself after purchase. If this fails, you will have to go through the 999 possible combinations. About a half-hour's work. Consider it something to do while commercials are running on TV. Have fun!12. HELP ME! What is the difference between a 'PIN NUMBER', a 'LOCK CODE', and a 'PUK NUMBER'?That happens when the PIN code is entered incorrectly numerous amounts of times. Call your service provider, give them your name, and your phone number and they should have the PUK number. No, you do not have to bring it to the store. A PIN number is a Personal Identification Number, it could have multiple uses depending on the phone. A PUK lock can be fixed by using the top paragraph.13. How to turn off the number lock key?you just have enabled the numeric keypad. find the key "Num LK" on your keyboard. normally it is inline with the F keys on the right. to disable press and hold Fn key Num LK key. you can do the same if you want to enable the numeric keypad again.14. I am locked out of my samsonite suitcase with 3 number lock,000 doesnt work nor code I entered,help please!?You do not say if the lock is fitted to the suitcase, or if it is a "freestyle" lock.... If you have fitted (i.e. replaced) the original samsonite lock, check your work. It could be that something has slid out of place and sealed the lock. If you have replaced the old lock with another samsonite one, I would suggest saving your time, and call the nearest Samsonite distributor to see if they have something akin to a "master key" which may get you out of trouble. If the new lock is TSA approved, you may be able to get help from a department store, if they have the overriding tool which these locks depend upon. Other than that, try and find a friendly locksmith or keycutter who may be able to either break the lock, disassemble it or otherwise let you in. Good luck and happy travelling!

Rapoo V808rgb Game Mechanical Keyboard Evaluation Is the Top Level in Quality and Feel
Rapoo V808rgb Game Mechanical Keyboard Evaluation Is the Top Level in Quality and Feel
When it comes to mechanical keyboards, many players may think of cherry for the first time. Cherry MX axis has become the symbol of most high-end mechanical keyboards because of its reliable quality and excellent hand feel. Rapoo has launched many mechanical keyboards equipped with cherry MX axis before. Recently, rapoo's new v808rgb game mechanical keyboard is still equipped with cherry axis, Let's take you to understand it carefully.Evaluation of rapoo v808rgb game mechanical keyboard: unpacking & appearance analysisOn the package, rapoo v808rgb still adopts the family style. The product rendering drawing, model and other marks are printed on the front, and the shaft type is also marked on the left. Rapoo v808rgb has four shaft types. This time, we received the red shaft version.In terms of accessories, rapoo v808rgb is equipped with a micro USB data cable and a traditional red key dialer due to its separate key line design.Rapoo v808rgb does not use too many fancy designs in appearance design, and its circumference reaches 445mm × 144mm × 41mm, and although the surface material adopts ABS, the keyboard weight still reaches 1.1kg, giving people the first impression that it is very low-key, calm and solid.Above the keypad is the indicator area, which respectively indicates the keypad locking, win key locking, case and other functions. At the same time, rapoo v808rgb has full key programmable function, and the top multimedia keys can be customized by driving.It can be seen from the side skirt that the keyboard still has a certain thickness, which can better fit the hand even without the use of foot support. The design of embedding the key cap into the keyboard can also reduce the occurrence of dust to a certain extent and better protect the shaft. However, compared with the suspended key cap, the cleaning is not so convenient, and the key cap needs to be removed to be better cleaned.The bottom of the keyboard is also made of black frosted ABS, with an information nameplate in the middle and a drain hole below, indicating that rapoo v808rgb has a certain waterproof ability, which can quickly discharge the liquid in case of liquid intrusion and avoid damage caused by backlog inside. It is equipped with four long strip anti-skid foot pads, and the foot support part adopts two-stage design, which can be adjusted to the appropriate height more accurately.The keyboard adopts a general micro USB interface and is equipped with a three-way cable slot.Evaluation of rapoo v808rgb game mechanical keyboard: axis analysisRapoo v808rgb adopts the original cherry MX shaft. There are four kinds of shaft available: red, black, green and tea. The one in our hand is the red shaft version. The pressure of the red shaft is not large in the hand feeling. When pressing, it goes straight up and down, with good rebound strength at the bottom. It is light, flexible and labor-saving. It can respond quickly in the game without causing fatigue after long-term use, It will not have obvious noise like the green axis. It can be said that it is a more versatile axis body, which is very suitable for small partners who want code words and like playing games.The long axis body still adopts the common satellite axis design. In the long key position such as the space bar, the hand feeling will inevitably be softer, while the hand feeling of key positions such as shift key is not much different.The key cap is made of ABS material with two-color injection molding. The surface is frosted and feels comfortable. The concave design in the middle is more in line with the ergonomic design. There are stiffeners in the key cap to ensure the strength. There is no burr inside and the edge is relatively flat. The workmanship still meets the standard of flag ship.Rapoo v808rgb game mechanical keyboard evaluation: RGB colorful backlightRapoo v808rgb is equipped with about 16.8 million color magic RGB backlight system, and has a variety of lighting modes. It can be quickly switched through FN key combination, and the brightness of five gear backlight can be adjusted. Through the drive, there are more adjustment options, and the playability is very rich.Evaluation of rapoo v808rgb game mechanical keyboard: Performance & Game measurementRapoo v808rgb supports full key non impact function, which can avoid misoperation caused by key conflict in the game.Apex HeroesIn terms of games, we choose apex hero, the hottest FPS game at present. In such games, whether there can be coquettish walking depends on the keyboard. In the game, rapoo v808rgb brings good response speed, and the operations such as sliding and jumping are relatively easy. The red axis straight up and down can also make your operation faster, combined with the colorful RGB backlight, The sense of game is absolutely amazing.Evaluation summary: Overall, rapoo v808rgb is a relatively stable update of 800 series. Although there are no free hand holders and other accessories, combined with the price of 499 yuan, it is also a cost-effective choice in high-end keyboards.In terms of hand feel, it is the least worrying point. The original cherry MX shaft is at the top level in quality and hand feel. Rapoo v808rgb shows the characteristics of the original shaft well. Combined with 16.8 million color and colorful RGB backlight and rich function driver, it makes the keyboard play more diverse. Rapoo v808rgb will be a good choice if you want to taste the original cherry MX shaft.

Four-day itinerary in Guilin, Guangxi in May 2019
As the saying goes, "Guilin's landscape is a fake world." Today, we came to Guilin, a dreamlike fairyland. It was noon when we arrived in Guilin.

Every time it went, the oars would "cut" beautiful and regular waves. Driving on the river in Guilin seems to be dreaming.Next stop: Gudong WaterfallHere we can have the most intimate contact with the mountains of Guilin and the water of Guilin, put on straw shoes and roll up the trouser legs to experience the coolness of summer in another way!

The scenery is beautiful, birds and flowers are scented, and the air is fresh. Not only can you feel the fun of walking along the waterfall and playing in the waves, but also the excitement of walking through the jungle.Next stop: XingpingThe beauty of Guilin lies in the Li River, and the beauty of Li River lies in Xingping.
