Take a hundred inch large screen with you, and experience it in a brick cast Jinshi handheld cinema




▼ It is said that in every "Sao Nian", there will be one Dream. The living room is set with a TV, and the bedroom is set with a projection, so that the guests can sit in the living room when they come; To enjoy, play projection in private space. Especially in the past two years, It can be said that bamboo shoots are springing up everywhere. The TV is getting bigger and smaller, and the projection is getting smaller and smaller. At the beginning, there will be the protagonist to introduce to you today - Zhuantou Jinshi Palm Cinema! This is a portable projection that can be easily held in the palm of your hand. Its size is only one circle larger than the usual power pack, and its weight is less than 500g. It also has its own power supply, supports voice recognition, gesture control, and child eye protection functions. Its physical resolution has reached the 720P standard, and the overall hardware configuration is fairly good. As for its specific performance in use, follow me to have a look!


▼ Brick investment ·The outer package of the intelligent projection of Jinshi is square and square, which looks simple and generous. The gray white stripes make the whole box look three-dimensional. The lower right corner is printed with the "Juneto" brand logo.

▼ Open the box, and the inside is placed in order; In order to facilitate the projection and the removal of the remote controller, a blue pulling cloth strip is also designed.

▼ The projection size is 11.8cm * 11.8cm * 2.725cm, which can be considered as a small and smart one and can be easily grasped by one hand. The machine adopts 8-core 2.0GHz CPU, four nucleus Mali-450MP2  GPU , DDR3 1G  RAM , 8G storage space, and support Bluetooth 4.0.

▼ Compare a 5-inch mobile phone with this projection, and you should have a more intuitive impression of its size.

▼ The remote control is relatively small, with a 9-button design and button battery power supply. The overall feel is comfortable, but for intelligent projection, it is not convenient because of the lack of mouse mode. Thanks to Brick Investment ·Goldstone supports external mouse, so that some programs can be used normally.

▼ Compared with the projection itself, the power supply of the projection is a bit large, but it is more refined. The power output of 12V - 3A has passed the 3C certification, and the quality is relatively reliable.

▼ The whole shell of the projection is not mixed with any plastic material. All of the 2.5D glass panels are used. The overall style is very similar to that of Apple products, and the same metal oxidation and CNC processing technology as Apple products are also used. In addition to the "Juneto" logo on the top of the projection, there is only one gesture signal receiving window below.

▼ In addition, this projection uses a hidden touch button, which can be awakened by touch at any time. The touch sensitive ammonium key is the same as the key on the remote control, which means that you can play at any time without the remote control.

▼ Behind the projection, from left to right are the power switch key, MIC hole, headphone hole, HDMI HD input interface, two USB 2.0 interfaces, and power interface. However, the light sensitivity of the material behind is slightly poor, which is not exquisite enough. In addition, the physical key of the power supply is slightly hard to handle, which is not very comfortable to press.

▼ In terms of lens, the brick casting stone adopts 0.3”DMD High transmittance coated lens, official said the brightness reached 250 ANSI lumens. The front panel and both sides of the projection panel are designed with very artistic irregular cooling holes. If you don't pay attention, you will think it is an artistic pattern.

▼ The four corners of the projection are not square as designed, but have a slight radian, which makes the whole fuselage more harmonious, comfortable and not too rigid. Built in machine The 5000mAh battery, however, is not ideal in terms of battery life. It can only support about one hour of playback time.

▼ The back of the fuselage is only printed with bricks ·Some relevant information of Jinshi is not designed for fixed threaded holes. Maybe the designer thinks that threaded holes are not practical for such palm projection, but will affect the overall beauty. But I personally think it is necessary to have threaded holes. No matter at home or outdoors, projection and tripod are versatile.

Next to the lens is the projection focusing ring. In the actual focusing process, it is different from the general projection focusing ring. It needs many turns to adjust to the appropriate effect, and the damping is not obvious. This needs to be improved, or the focusing time is too long.



▼ As a projection, although it is a portable micro investment, users still attach great importance to some of its related parameters, so I will first introduce Some test data of BRIC Investment and Jinshi Micro Investment will be presented to you for reference, but they must not be professionals. The tools used are also amateur products. The measured data will inevitably be different, so they are only for your reference.
[Brightness test] I believe that for projection, brightness has always been one of the indicators most concerned by users. Here I remind you that the high brightness of commercial projection is to meet the needs of office use in the daytime, while most of the home projection is used at night, and most of it is used in a completely black environment. Therefore, too high brightness will hurt your glasses, So I also advise you that if you don't have special needs, household projection doesn't need too high brightness. Of course, some friends who like watching TV by projection in the daytime can ignore my words. Since the indicator of brightness will greatly affect the user's choice when purchasing, basically all projection manufacturers will deliberately raise the lumen of the machine in the propaganda. We are used to this, so let's take a test together Brick investment · Jinshi micro investment How much is the true brightness!
In order to test more accurately, I used the ANSI 9-point test method, that is, to measure the illuminance of 9 points in the picture, and then the average illuminance of 9 points is the average illuminance of the whole screen, and then multiplied by the picture size to get the brightness of the machine, that is, the lumen number. The size of projection projection in the figure below is 1.1 meters wide and 0.61 meters long, that is, the area is 0.671 square meters. The Lux values of 9 points are 139, 148, 135, 154, 154, 147, 154, 155 and 145 respectively. Then calculate
ANSI brightness is about 100 lumens. And officially publicized There is still a big gap between 250 ANSI lumens.

[Noise test] For projectors, noise is also a concern of many friends, because it will not only affect the mood of users when watching movies, but also may damage users' hearing due to loud noise. Let's first take a look at the difference between noise and ordinary people:
0 - 20 decibels: basically not felt at this level.
20-40 dB: Quiet, like whispering.
40-60 dB: Ordinary, ordinary indoor conversation.
60-70 dB: noisy, nerve damaging;
70-90 decibels: very noisy, nerve cells are damaged.
90-100 dB: increased noise and hearing loss;
100-120 decibels: unbearable, temporary deafness after one minute.
Above 120 decibels: extremely deaf or totally deaf.
Because the professional test noise is conducted in an absolutely silent space, the data obtained is more accurate, of course, I can't do it. What I can do is to choose a relatively quiet environment. The test time is at 1 a.m., and the surrounding environment is relatively quiet. At this time, the ambient noise is 35.4 decibels. In order to achieve the relative accuracy of the data, I adopted a more common noise test technique - five directional fixed-point test method. That is to say, the same distance of 50CM is used to sample the data in the front, back, left and right directions of the measured object, and then the five data are averaged to obtain a relatively accurate result. The test results show that the values in five directions are 45.1, 43.7, 41.6, 43.2 and 44.9 respectively, so the final noise value is 43.7dB, which is acceptable.

Temperature test We Yes, traditional light bulb projectors have always been a big fan of fever. If you watch a movie too close, you can sweat Heat has always been a key issue of concern to users, and if the volume of micro injection is too small, it will certainly affect the normal operation of the machine. How does this brick cast stone perform in this respect? Come and have a look with me!
The machine has been on for more than two hours, and the temperature measuring gun and machine shadow machine have been placed in the same environment for more than two hours. Recently, the high temperature here is basically about 33 degrees, and I sweat every minute without turning on the air conditioner, so I choose to turn on the air conditioner for testing, and the room temperature is about 24 degrees. According to the infrared temperature measuring gun test, most of the temperature on the surface of the machine is about 34 ℃, the maximum temperature on the front is 38.4 ℃, and the maximum temperature on the bottom of the machine is 40.7 ℃. This data is also acceptable, but in such weather, if you do not turn on the air conditioner to see the projection, I think it will be relatively high.

[Power test] In terms of power consumption, when the projection is in standby state, the power is 2.26W per hour.

The power during no-load operation is 17.65W/h (Figure 1), and the power when attaching a 320G mobile hard disk is 20.39W/h (Figure 2). In general, the power is relatively low.

[Virtual focus/out of focus test] Zhuantou Jinshi is adopted as one DL P technology projector, while DLP technology has certain shortcomings, that is, it is difficult to achieve full screen synchronous focus on the projection image, that is, you start up and adjust the middle position, and there may be virtual focus in other places, and vice versa. In short, it is not clear on the full screen, and this problem may not be solved temporarily, as long as you use DLP, This problem exists more or less, but some manufacturers will use technical means to minimize this phenomenon. that Brick investment · Jinshi How will they perform in this respect? We can see from the following figure that the text in the middle and right of the whole projection screen is relatively clear, while the upper left corner and lower left corner are slightly blurred.

After the machine has been running for 30 minutes, the vagueness of the text has increased, and the focus needs to be refocused.



From the test results in the previous section, we know that the actual brightness of this brick and stone micro investment does not reach the official 250 ANSI lumen, how about its display effect? Let's take a look at the following live pictures!
Figure 1:

Figure 2:

Figure 3:

Figure 4:

▼ From the above several live pictures, we can see that this The actual display effect of brick cast and gold stone is not bad, the overall color saturation of the screen is very good, and the color restoration is also more realistic. They also performed very well in terms of details. Let's see the screen shooting effect of two local high-definition films:
Figure 1:

Figure 2:

So as I said before, home projection does not need too high brightness. When watching films, several people will watch them in broad daylight or with the lights on. After a trial, I personally feel that the projection quality of Brick and Stone Micro Projection is very excellent, fully meeting the needs of home entertainment.


Brick cast · Jinshi adopts a flat square menu style in terms of UI, which can be selected from left to right. The main interface is divided into three parts: "online video", "lifestyle" and "settings". Personally, I don't like this interface very much. It will increase the steps of operation. I prefer the one screen interface, which reduces the level and logic as much as possible. For example, the five major parts of "online film and television" all point to the same APP. I don't think it is necessary at all. It is better to customize five different film and television platforms.

▼ Application list interface:

▼ As a projection setting, it can be completely placed on the main interface, but it is hidden in the application list. From the settings, we can see that, Brick and stone support infrared eye protection and gesture recognition. In addition, we can also set different projection methods according to different use environments. Of course, for micro projection, we basically only use the "desktop forward projection" method. In addition, brick casting and stone support automatic trapezoidal correction. Because the machine I got is not an official machine, some functions are not perfect yet, and there are also some bugs in use. For example, every time I turn on the machine, the projected image is reversed, and the projection mode is "desktop forward projection".

▼ For the "infrared eye protection" function, my initial understanding is that as long as you stand in front of the lens and look directly at the lens, the projector will automatically turn off the light machine, so as to achieve the effect of eye protection. But after the test, it is not the same thing. It almost blindsided me. The real "infrared eye protection" of the machine is that it will automatically turn off the light machine only when the projection picture is completely blocked. I can only say this: Then, there is no egg!

The setting interface of Brick Investment · Jinshi adopts the original Android interface, but it is not necessary to open it when using projection. As can be seen from the following, Brick investment · Jinshi It supports 2.4/5G dual band mode, so the online video playing process will be more smooth.

Brick Investment · Jinshi supports online upgrade and local upgrade, which is generally convenient. It is said that the official system version will be pushed this week. At that time, voice assistant and gesture control can be used normally.

▼ The system has its own "Dangbei Market", so we can easily download various applications to expand the projection function.

▼ The system has its own QQ music. Usually, if you need to listen to music, you can choose the online mode. As for the local area, Zhuantou Jinshi also supports some conventional music formats, such as MP3 and AAC.



▼ It is obtained through the test of rabbit test software, Brick investment and Jinshi scored 19729 points, which is really not high at present, but it is basically enough for micro investment.

▼ The test score of NenaMark2 is 59.8fps, so it's reasonable.



The online content provider of BRIC Investment · Jinshi is ICNTV, It owns CCTV's exclusive Internet sports resources, Champions League, NBA, Enjoy the Olympics all the time. It has also integrated Tencent Video, and has a huge amount of film and television resources. The duration of video resources is up to 1.5 million hours, and there are 1000 hours of content updates every week. How can you see so much content.

▼ The video quality is very good, and the clarity and buffer are satisfactory.



▼ The summer vacation is coming soon, with this model Zhuantou · Jinshi, the children at home should be the most happy. What do you want to see in cartoons? Don't worry about advertising. It's really exciting. Moreover, as the reflection light source, the projection is more environmentally friendly and eye friendly, so parents need not worry too much about the damage to their children's eyes.

▼ Friends who like watching live broadcast can also come Download the live broadcast software, and watch hundreds of stations at random, such as the following“ ”The effect is strong and the buffering speed is very fast. There are many HD channels for you to choose from.

▼ The live broadcast effect is very good, and the source can be automatically changed according to the network environment.

▼ For most men, the recent period is a time of craziness, when they meet three or five friends, put on frozen beer, and watch the ultimate confrontation in the projection, do you have a feeling of boiling blood?



Brick Investment · Jinshi supports external mobile storage devices, so we can easily watch movies and TV content in USB flash drive or mobile hard disk. Moreover, Zhuantou Jinshi can correctly identify hard disk partitions.

▼ According to the test of Anthare video evaluation software, 2 out of 30 sample videos are not supported, 12 are incomplete, and 16 are perfect.

▼ The two unsupported formats are also relatively unpopular coding formats, which are not commonly encountered.

▼ The 12 samples with incomplete support are mainly audio formats that are not supported. From here, we can see that Zhuantou Jinshi does not support AC3 and DTS audio coding.

▼ Some of the most common video formats, Brick investment, gold and stone can be supported.

▼ In addition, I tested more than ten 4K movies, all of which can be played normally.




▼ In addition to watching movies and chasing dramas, it is also excellent to play games when you are bored, especially playing on a large screen of more than 100 inches. Brick cast · Jinshi has a built-in "small Y game" platform, which contains a large number of games, including remote control, flying mouse and handle.

▼ This kind of games, such as "Fight the Landlord" and "Mahjong", are especially suitable for playing with remote control. They are very well optimized and easy to operate. Moreover, there are often some physical reward competitions. It is really good to get prizes while playing.


▼ In addition, Zhuantou Jinshi is a projection that supports Bluetooth, that is, if you have a Bluetooth handle, you can play more types of games.

▼ For example, my favorite arcade game at school, Street Fighter, is really different when I lie in bed.

▼ As a portable projection, it is also a great blessing for business people who often travel. Take me as an example. Every month, there will be nearly a week of business trips outside to talk about cooperation with customers. Projection is often used. But sometimes, there may be no projection in the place where we talk with customers, or in other cases, But it's uncomfortable for several people to squeeze their heads to look at the computer screen. At this time, Brick investment · Jinshi can really be used. The hardware requirements are not high, there is a white wall, and the environment is not too bright for business practice, and Brick and stone support office software, PPT presentation is basically the same as on the computer.

▼ As a micro investment, its playability is very large. It does not require high environmental requirements. It can be projected wherever it is white, even against the ceiling. It is really a pleasant thing to find a comfortable angle when lying in bed.



As a portable intelligent entertainment micro investment, it can be said to be very good in terms of content, with a large number of legitimate resources. With fashionable appearance and small size, it is very suitable for going out and carrying. Whether it is for business trips or camping in the wild, Zhuantou Jinshi is a very good companion. Because it is an internal test model, some functions are not perfect at present. For example, voice assistant and gesture control are not ideal, and there are also some bugs. However, after the completion of the system push update this week, there will be a surprising performance. I am looking forward to this, and I believe that the brick investment company will not disappoint you.
