What can a projector do? In the past, you may answer that projectors are of course used for office, teaching, training, etc. However, with the development of science and technology in the past two years, projectors and other products are no longer the kind of "giant" Pa ", especially home projectors, is also called "home theater", compared with the traditional projection, this type of home projector is not only small, easy to carry, and also built-in intelligent systems, gameplay can be described as very Much, and I experienced this nut P2, which not only has "value" but also "strength"! So this nut P2 really can bring a cinematic visual experience? Now I will take everyone to experience the charm of this nut P2!
The design of the nut P2 product packaging I will not introduce much, as with the projection of other nut series, are all black carton packaging, and damping sponge embedded in the nut P2 around to prevent the transit, because of the shock Causes product damage.
Before P2, there was also a P1, so P2 can be understood as an upgraded version. There are different improvements in design, process design, etc. Nuts P2 comes with a specification of AC 100V-240V 50 in the package. /60Hz power adapter.
In addition the package also comes with an infrared remote control, nut P2 remote control button layout is also very simple, in addition to the common direction, determine, return, home button, etc., the remote control also has a focus key, allowing users to adjust the projection at any time The clarity of the effect. (PS: Nut P1's focusing method is manual, and nut P2 is changed to electric focusing)
Another volume control button is designed on the side of the remote control.
Nuts P2 in the appearance of the use of anodized aluminum metal design, gives a design feeling of Apple products, while the nut P1 is a plastic + metal design, so that the nut P2 in the appearance, process design is very large Change.
In addition to the remote control and power adapter, there is a metal magnetic base in the package. The role of this metal bottom is not only to stabilize the body, but also to protect the projection lens and act as a lens protection cover.
Nut P2 built-in dual speakers, the sound quality is not bad, even at the maximum volume gives a "deafening" feeling, so do not look nuts P2 is a portable projector, but the volume is really large, in line with "home theater "Location!
The left and right sides of the nut P2 are speakers, but the position of the left speaker is also the hole of the nut P2. In addition, when the nut is running, the noise of the exhaust hole of the nut P2 is generally normal. After personal experience, it is considered to be within an acceptable range. Inside.
Nut P2 built a 15600mAh lithium battery, life time is 5 hours. Because it has a built-in lithium battery, it doesn't need to be connected to the power cord, and it can be used directly. This "wireless design" makes the portability of this product greatly improved, so that you can play movies anywhere with nuts P2. The phrase "there is a place where me is the cinema" is used to describe the nut P2 as the most appropriate. In the interface design, nut P2 has a RESET reset hole, an HDMI interface, a USB interface, and a power interface.
In terms of key design, the nut P2 differs from the nut P1 in that the whole nut P2 is only designed with a power button. This design makes the nut P2 look more integrated with the “esthetic senseâ€, unlike the nut P1. In that case, one side of the machine is full of buttons, greatly affecting the “face valueâ€. In addition, the nut P2 also has a Bluetooth speaker mode. In the case of shutdown, short press the power button to allow the nut P2 to enter the Bluetooth speaker mode. You can use your phone, or other digital device, to connect Nut P2 to play music.
Nut P2 In addition to the above-mentioned several data interfaces, there is a standard screw hole below the machine that can be used with a tripod. Maybe it is because it is positioned as "mobile portable." The nut P2 does not have a cable interface, but instead uses a built-in WiFi connection to connect to the network. Because the entire machine has fewer openings, the entire machine looks very "pretty."
In terms of projection, the nut P2 is equipped with a DMD optical projection chip. The projection screen resolution is 1280720 (compatible with 1080P, 2K video playback), and the projection size is 40-180 inches.
On the lens side, the nut P2 uses a high-transmission coating lens with a maximum brightness of 250 ANSI. Many people may feel that the 250 ANSI brightness is somewhat lower, but currently the "mobile portable" projectors are in the 250 ANSI brightness range. In the meantime, if you don't need "mobile portability," then consider the Nuts G series, or the X series. The ANSI of these projectors has reached 500 or more, but the same is no nutty P2 so easy to carry, no more The built-in power supply is designed to use only the power adapter. (Another 250 ANSI represents the Lumens lumens, if converted into domestic lumens, 250 ANSI is probably 1500 domestic lumens, but there is no uniform standard for converting ANSI Lumens lumens into domestic lumens. At present, many of the more than 5,000 brand projection products, ANSI or 500, if the projection lumen data does not follow the ANSI label, only a 3,000 lumen is marked, then this is the domestic lumen data, rather than the standard ANSI, so 250ANSI lumens does not represent 250 lumens!)
The design of the nuts P2 is similar to a cup. The weight of the whole machine is only 1kg. It is very convenient to carry. Through a preliminary appearance experience, it can be concluded that in the same price of the product, the nut P2 from the design, craftsmanship work , Yan value and other aspects are relatively advantageous, and the cup-style design is more portable, but a product is only appearance, Yan value is not enough, let us take a look at the system experience of nut P2!
In fact, Xiao Bian had previously experienced the system of nuts P1. At that time, I thought that the idea was really "bad". After continuous optimization and updating, the current built-in system of the nuts P2 can be said to have a completely new change. , Nut P2 JmGO OS system is based on Android depth customization, the entire JmGO OS gives me a sense of the PS4 system interface.
After the nut P2 is powered on, it is recommended that you first connect to the WiFi. In addition, the nut P2 supports two 2.4G/5G WiFi modes. In terms of configuration, Nut P2 uses an Mstar-6A628VX quad-core processor with a GPU of mali-450 MP2, a 1G storage, and a 16G storage space (8GB eMMC + 8GB TF card).
The functional interface of JmGO OS is divided into upper and lower rows. The upper row is a functional interface, such as personal center, WiFi settings, system settings, signal sources, etc. To be honest, the previous JmGO OS function layout is very "chaos", and now the JmGO OS function interface does a very "order" Basically, it gives a feeling of "at a glance".
In the system settings, in addition to several common settings, JmGO OS also has a key optimization, trapezoidal correction, lens with more effects, lifting, rear projection and other functional design.
As I said before, the nut P2 is a design method that uses electric focus adjustment. The remote control can quickly focus the projection screen, which is very convenient. If a user has used a nut P1, you certainly cannot forget the “manual focus†of the egg!
Nut P2 also supports the playback of 3D movies, but you need to purchase additional 3D glasses yourself. And 3D also has a variety of modes to switch, such as left and right, up and down, automatic and so on.
The built-in video resource of Nut P2 comes from Litchi TV. Litchi TV also has the advantage of rich resources and fast update speed. You can enjoy high-definition movies at home without leaving your home. However, some movie resources still need to pay. When watching a movie, you can switch the video format via the remote control. There are three video formats: HD, 720P, and 1080P.
Most people buy smart projectors in order to enjoy high-definition movies. In addition to the rich movie resources, JmGO OS also has a very rich 3D movie resources! After wearing 3D glasses, I feel no need to spend money to go to the cinema later. In the movie, unless you enjoy the atmosphere of a movie theater, a nut P2 can satisfy any viewing requirements.
I don't have to say more about TV dramas. The richness of video resources is also an advantage of the Nut P2. It can completely replace TV and make the Nut P2 your mainstream playback device. Coupled with the easy-to-carry features, whether it is a business trip, or outdoor barbecue, as long as the brightness is enough to achieve the P2 playback requirements, where you can easily chase drama.
The advantage of having a smart projector is that not only can you enjoy large movies on your own, but you can also allow your children to enjoy the “big movieâ€, but I personally recommend that children have a “degree†to watch the projection. Otherwise, don’t look over them. vision.
Whether it is a movie, a 3D movie, or a TV show, a children's program, an animation, etc., it is all in JmGO OS! So in terms of resources, you can rest assured that you don't have to worry about buying a nut P2 and you find that you don't have "something" to go home with. Look.
In addition to being able to watch movies, Nut P2 can also play games. However, there are no more movie resources than movie resources. But it can be seen that JmGO OS is gradually increasing the update of game resources. In addition, through the Nut P2 HDMI interface, you Can be connected to a computer, or handheld, with a projection projection game screen look very cool.
If you really don’t know what kind of video resources to watch, you can choose to go to the “all channels†function to see if there are any videos you like to see. JmGO OS covers a total of 31 categories of video resources.
But what is the last gui in the "all channels"? In addition, personal advice can increase foreign television programs, or Taiwan, Hong Kong television programs.
But what is the last gui in the "all channels"? In addition, personal advice can increase foreign television programs, or Taiwan, Hong Kong television programs.
If you think JmGO OS's video resources are still not what you want to see, or want to watch other TV live, you can install a third-party APP to watch, JmGO OS is based on Android depth customization, optimization, scalability, and playability are very Not bad.
In fact, you can completely use the nut P2 as a TV, install a third-party software platform, you can download some somatosensory games, air mouse games, smart TV can play, nut P2 can play.
Well, this is the system experience of the Nut P2. Taking the above experience into account, my personal feeling is that the resources are rich, the system interface is fresh, the functions are arranged in order, the experience is very good, and the JmGO OS is not as complex as the previous version. The user's learning cost of the system can be said to be zero. In the final test, let's take a look at the projection effect of Nut P2!
The maximum projection size of the nut P2 is 180 inches, the minimum is 40 inches, and the brightness is 250 ANSI. Everyone sees the graph effect at night. It is very clear, and it is enough compared with the TV. Many people see here and want to Do not want to directly throw a "try to turn on the lights, definitely not clear", first of all do not say that the lights can not be seen clearly, who will see the projector to see the light to see it?
When evaluating other projections before, many people said that I got a TV screen to project images, and home micro-projections simply did not have such high brightness. For this reason, when testing the projection screen of the nuts P2, I leaned on the wall. With a white canvas, we can see that the projected screen shots of the camera are used to capture some of the projection screens on the canvas. This also illustrates the situation. Completely "real".
Returning to the projection screen, we can see that the picture projected by the nut P2 is very satisfying both in terms of sharpness and picture color, so 250 ANSI is enough, unless you take the P2 to the open air for projection.
(Let's take a look at the real shots of a few nuts P2 projections!)
(Isn't it giving you a very shocking feeling? It's a bit unbelieving that a projector with such a small size can actually throw such a clear picture)
(But again, in the case of light, the projected picture will be affected. After all, the brightness parameter is there, but nut P2 is not suitable for use during the day. I will tell you later)
(The above projection screens are real shots of the camera, and for the sake of the beauty of the picture, each picture is only cut out to the black side)
This is a real shot of my 2K video playing with nuts P2. By the way, this should be a hardware limitation. Nut P2 does not support 4K video playback.
In this experience, I added “covering material†to each projection screen of the nut P2. The main purpose is to tell everyone that the projection brightness of the nut P2 is sufficient for our daily use.
I prefer to play arcade games with nuts P2, with Bluetooth game controllers, and how to play with them.
Finally, let's take a look at the projection images during the day! I know that there may be people who say, "This effect cannot happen in the daytime," but the fact is that it is the effect of shooting during the day.
Another real shot of the daytime projection effect, you should be able to see the day outside the window! As for why the room is so dark, because I put the camera's focus out of the window. In short, the effect of the projection of the nut P2 is somewhat unexpected. In that case, the nut P2 can satisfy the projection of various scenes. Even during the day, it can be watched, but I still think that since it is a cinema-like treatment, then the nuts are used at night. P2 is best.
Experience summary: The advantages of nuts P2 I believe we should understand through this evaluation! In appearance, nut P2 is similar to the cup-shaped design, 1kg weight is very easy to carry, and the process, anodized aluminum metal material can give You bring a good touch, and resources, this is even more needless to say, in addition to the restrictions on the movie, you can see the large, nut P2 can see! And the most important projection effect, through my various projection tests It can be seen that the projection screen of the nut P2 is also quite good. In summary, the nut P2 can be said to be both attractive and powerful, if you are looking for a portable home projector, or you are on a business trip, For training new employees, etc., Nut P2 will definitely make you satisfied!
The main circuit of the equipment is the full bridge controlled circuit and the trigger circuit is the programmable integrated circuit. The phase-shifting, fixed width and modulation of the pulse are all digitized, and it does not need any adjustment for the section of the trigger. It has the features of high reliability, high pulse symmetry, strong anti-interference ability, quick reaction, as well as the advantages of no heat-generating, constant current, energy-saving which is compared with the discharge with the electrical resistance.
