Foreword | Raytheon K71C Black Diamond Mechanical Keyboard

▲ The first time I saw the Thunderobot K7 series mechanical keyboard was on the Thunderobot Weibo, and I was attracted by the silver shiny keycaps at the first sight. It is the first time to play with plated keycaps that have been treated with various surface techniques. It is said that the concept image is beautiful and the reality is cruel. So what about this all metal key body and electroplated key cap Thunderobot K71C? Let's unpack and experience it slowly.

Packaging | Raytheon K71C Black Diamond Mechanical Keyboard

▲ It's a great honor to get the chance to try Lei Feng.com. It's said that Lei Feng.com's try LOGO matches Raytheon's LOGO quite well. Raytheon K71C adopts double packaging, the outer packaging is primary color pulp, with red Raytheon LOGO, and the product model, serial number, manufacturer and other information are pasted on the lower left corner side.

▲ There are tamper proof labels on the left and right of the package. If you buy through e-commerce, check whether the labels are intact when you receive the goods.

▲ The inner package is in red letters on a black background, which is relatively low-key, so the LOGO used by Lei Feng is particularly eye-catching.

▲ There is a lot of information on the back of the package, including product function keys, product models, bar code labels, and product features.

Unpacking | Raytheon K71C Black Diamond Mechanical Keyboard

▲ The buckle of the inner package has not been hemmed, and it is easy to be damaged by repeatedly turning on and off. I hope the manufacturer can design a buckle that is not easy to break. Although most people don't want the box anymore, for someone like me who likes collecting peripherals, I still don't want the box to break. After opening the inner package, there is a protective cover on the upper part to prevent the keyboard from being crushed during transportation. There is a place in the middle where a finger holds it, which is very good.

▲ Open the cover, and you can see that the keyboard is wrapped with a layer of sponge paper, fixed with foam sponge twice, and the wire and key puller are fixed with velcro.

▲ The included key puller is red, which doesn't match the overall style of the keyboard. Fortunately, it is conspicuous and not easy to lose.

▲ There is also a product manual, a letter to Lei crazy, and a warranty card in the package. The style of the cover is a bit antique.

Keyboard | Raytheon K71C Black Diamond Mechanical Keyboard

▲ Let's take a look at the whole keyboard, with narrow frame design, electroplated key cap and aluminum alloy frame integrated. The picture looks silver gray, but it is actually black gold.

▲ The keyboard adopts the floating key design, following the current popular elements. The keyboard adopts standard 104 keys, with dimensions of 48cm * 17cm * 5.5cm and weight of 1.35kg.

▲ The design of high front and low back of the keyboard is mainly due to the fact that the two front foot pads at the bottom of the keyboard have a certain height, resulting in a certain slope.

▲ The key cap layout adopts the ergonomic design, and the overall structure is stepped. The first three rows of key caps are high in front and low in back, and the last three rows are low in front and high in back. The three screws on the side are very eye-catching. It depends on my personal feeling whether they are beautiful or ugly.

▲ The keyboard adopts a narrow border design, which can be freely matched with the hand rest. I like the soft leather trustee, and the customized wooden hand rest is also very beautiful.

▲ The plated key cap is bright. I have seen ASDW key or ESC key change plating before, and all of them are plated. The effect is really good, and the color value is very high. On the keyboard layout, the multimedia keys in Area F are grouped into four groups, the Enter key is a "one" type, and the FN key is only arranged between ALT and CTRL on the right.

▲ In the direction key area, the traditional 9 grid and up, down, left and right keys are displayed, with the English LOGO of Thor in the middle. The keypad number area is also a standard layout, with three indicators on the top.

▲ The keyboard adopts the floating key design, which is fashionable in appearance and easy to take care of.

▲ There are three screws on the left and right of the keyboard, which are beautiful. What do you think? I think it is acceptable. After all, metal elements. Some bare screws also have a punk metal taste.

▲ When looking at black gold in the sun, there is a little purple feeling, which is full of metal texture.

▲ The keyboard frame is made of aluminum alloy, one piece of metal is spliced on the left and right, and the corners are grinded to prevent scratches, while increasing the gloss of the keyboard frame.

▲ The wire is designed in the middle of the keyboard. If you can customize the left, middle, right, or USB detachable type, it would be better. This is more user-friendly.

▲ There are gray woven packages outside the wire, and there are velcro fixed lines. If the color of the velcro is gray, it will look better. The anti-interference magnetic ring is in the same color as the wire, which is quite good.

▲ The USB interface is also gray, consistent with the wire, and the interface is gold-plated.

▲ Take a look at the back. It is made of integrated metal material, and there is an anti-skid foot pad at each of the four corners.

▲ In the middle is the pattern and logo of Black King Kong. And product model, voltage and current information.

▲ The same product model and barcode information are also pasted on the right side of the bottom. At the same time, a drainage tank is also designed on the right side of the anti slip mat. There are three gutters on the lower edge, one on the left, one on the middle and one on the right.

▲ The support foot pad itself has a certain height. Only one height can be adjusted, the support itself has anti-skid materials.

▲ This is the side condition of erecting support.

▲ This is the rear part of the support. The height is enough. When I play games, I will put it up. If I buy a hand support, it is not necessary to put it up.

Shaft cap | Raytheon K71C Black Diamond Mechanical Keyboard

▲ Raytheon K71C adopts the metal electroplating process to inject the double mold key cap, which has the appearance of the metal texture key cap, ABS material, and the key shaft uses the TTC green shaft. The key shaft parameters are as follows:

1> The color of the handle is cyan

2> There is a sense of paragraph when pressing the handle down to a certain position

3> There is a "click" sound when pressing the handle down to a certain position

4> Hand feel: light

5> Feeling force when pressing down the handle 2.0mm: 60.0 ± 10gf

6> Trigger stroke: 2.2 ± 0.6mm

7> Total stroke: 4.0mm

8> Service life: 50 million times

The parameters are very similar to Cherry green axis, and the total stroke and trigger stroke are almost the same.

▲ The space bar equal length key adopts the satellite shaft design, and the hand feel is really a bit fatter than the balance bar.

▲ When it comes to TTC, I have to talk a little. I really know something about TTC. Last year, I visited the factory in Huizhou, Guangdong, and had an exchange with their general manager and product R&D personnel.

▲ The picture above shows the assembly line of the green shaft in the production workshop. The genuine TTC axis of Kedian is uncommon. The Rapoo axis used by Rapoo keyboard is manufactured by TTC. TTC microswitches and decoders are still very common, including mobile phones, digital cameras, audio, electrical appliances, measuring instruments, and industrial control equipment. In addition, many of the keyboards, mouse microswitches, and decoders common to our peripherals enthusiasts are TTC, accounting for a high share of the domestic market.

The general manager of genuine Kedian once said that the mechanical axis is aligned with Cherry axis, and the microswitch is aligned with Omron. In addition, they have been doing this all the time. After seeing the mechanical shaft curve of their R&D laboratory, it is very close to the Cherry axis.

▲ The keyboard uses the metal plating process to inject the double mold key cap. Although it is a black gold version, it is also very bright in the light. To be honest, I prefer this light. The keycap is concave on both sides, and the letters and numbers are designed for light transmission. Without backlight, the indoor view is slightly dark. Although the key cap is very bright, it is easier to leave fingerprints. If it takes a period of time to clean, you can use a soft lens cloth and glasses cloth to clean it. It is found that these materials can be cleaned faster.

▲ The back corners of the key cap are meticulously made, and a layer of silver is painted on the chrysanthemum.

▲ The light transmittance of the letters is good. I can see the letters clearly when facing the sun, and the font is easy to distinguish. I remember that some keyboards, in order to pursue personalized fonts, had beautiful designs, but it was difficult to distinguish the letters D, O and G, which was a headache for those who were not familiar with the keyboard letter layout. This type of font is very beautiful and easy to recognize.

Light | Raytheon K71C Black Diamond Mechanical Keyboard

▲ Raytheon K71C Black Diamond is a two-color LED, the computer menu key and direction key are blue backlight, and other keys are red backlight.

▲ At present, the backlight can be turned on and off, and the brightness can be adjusted. It can be switched to the breathing light mode, and the breathing cycle frequency can also be adjusted. Of course, compared with the current ripple mode and the marquee mode, it is a bit monotonous. Although these modes are not commonly used and are more used for display, it is better to have them than not. I hope the manufacturer can improve them.

▲ It can be seen from the above figure that the light transmittance of the key cap is good, the font is clear, and the manufacturer has adopted ABS material for better light transmittance. The three indicators are red. It is found that the keyboard test software can also test whether the indicator works normally.

▲ Turn the backlight brightness to the maximum. From the side, there is also the effect of neon lights, which is very beautiful.

▲ Have you noticed that the arrow and ASDW letters are marked on the direction keys of the keyboard, and the keyboard can be switched through shortcut keys. The two ASDW areas are interchangeable, which is an interesting design.

▲ Unplug the key cap to see the light intensity of the key shaft, which is OK from the side.

▲ The direction key is an independent blue backlight, which is very different from the surrounding red light.

▲ The key shaft adopts chip LED light, and the upper half of the shaft body is transparent, so the light transmittance is also good, close to the brightness of the lamp bead. I didn't dare shoot vertically, otherwise the pictures would also be spent.

Light shortcut key:

1、 FN+HOME， Switch between normally on mode and breathing light mode.

2. FN+minus/plus sign, adjust the constant brightness and respiratory cycle frequency.

▲ Another video of breathing light mode, let's see the effect. I usually use two modes, namely constant light and breathing. I have played with Ripples and Horse Lanterns. It's OK to play with them. Usually, they are too fancy and easy to distract.

▲ Because I am a game house and like to play FPS shooting games, I naturally entered Logitech G500s, but the keyboard and the mouse are not compatible.

▲ I am a light pollution enthusiast, and all kinds of hardware and peripherals are involved in light pollution. However, this time, the red light keyboard is not compatible with my white light chassis. I will change a red light fan another day.

Test | Raytheon K71C Black Diamond Mechanical Keyboard

one Full key non impact test

▲ I put my phone on the keyboard, press all of them, and they all passed. The two red ones in the lower left corner are generated from my QQ screenshot. Full key non impact is very useful for current competitive games.

2. Game experience

▲ It is said that the green axis is suitable for typing. I often write in code, but I often play economic games for hours. This time I played for about 4 hours in a row to cross the line of fire, and found that Green Axis was still competent. Both movement control and box skipping can operate normally. However, I was wearing earphones, and I didn't care if the crackling noise affected people around me. If the dormitory or company plays games, I think it's better to play black axis or red axis. It's not good to affect students or be found by BOSS.
