Preface: The Story of Me and the Projector
I remember when I was in elementary school, I used a slide projector in the classroom. The teacher used a transparent slide paper that could be recycled. In most cases, it was ambiguous. Later, the school changed the overhead projector. It was the school at that time. More advanced projection equipment; now, the projector becomes a compact device that can be loaded into the pocket. The projector is no longer used only in meetings and classrooms. It gradually enters people's homes, does not require installation, and can even Take it with you and gradually evolve into "microprojection".
As a post-90s me, I am really experiencing the entire process of projection development. Before the major platforms have appeared projector trials, but unfortunately I did not get one, how can I always like to sit like DIY, then I handcrafted a bedroom theater for $10.
Ordinary magnifier and shoe box, let me transform into a simple bedroom projector, when I was happy to project to the wall, only to find ... ...
The DIY projector can only shoot about 40 inches of screen, and the texture is very rough, it is not clear. Even so, I was very happy at the time, and my sense of self-promotion soared.
Unexpectedly, shortly afterwards, I was fortunate enough to have access to the trial rights of the PaPa mobile projector. Want to know what kind of sparks I and PaPa projectors shine? Let's take a look together.
Unpacking: Small But High-end And Atmospheric
PaPa mobile phone projector uses a flat rectangular packaging, printed in the middle of the white background "PaPa" Logo, very eye-catching, strong contrasting colors make the entire package looks beautiful and atmospheric.
Like most smart products, the back of the packaging, printed with the company's two-dimensional code, web site and other information, not much to say here.
The author got a silver version of PaPa mobile projector. After opening the package, he can see that there is a white hard plastic as a buffer protection, so that the projector has to withstand the bumps in the express process.
The size of the projector is about 8.5cm8.5cm1.5cm, very small and exquisite, can be put directly into the pocket of clothes or trousers, easy to carry out.
Accessories are PaPa Mobile Phone Projector x1, Remote Control x1, Power Adapter x1, Manual x1, Warranty Card x1. The front of the projector uses Mac Book with the same material, from aluminum-magnesium alloy material, fine sanding process makes the feel very good, and packaging, the front is printed with a bright red "PaPa" Logo.
There are four pads on the back of the projector, which can be non-slip and shockproof. Unfortunately, there is no projection bracket in the attachment. Of course, we can also use a mobile phone stand and a tripod to form a projection bracket, but there is always some inconvenience, and the projector is also There is no function of tilt adjustment, so the projector must be placed horizontally, otherwise the image will be deformed, and using it without the tilt adjustment function of the bracket does make people more tangled.
The front of the projector is a lens and a cooling hole. The inside is a silent fan from Japan. When it is used, it will not hear the sound of the fan running, making it sound very good.
The sides are switches and heat vents, and the switches use a slightly recessed design that resembles a rubber material.
On the other side there is a focus knob and stereo, unfortunately the projector does not support the headset to play, like the author of this student party, sometimes watching a TV drama at noon if you put on the outside is likely to affect others to rest, so at noon to see TV dramas can only be used without a projector, and the projector's focus is also uneven.
On the back is the Micro USB interface, Mini HDMI interface, USB interface. U disk can be inserted through the USB interface, you can enter the U disk playback mode, which is excellent for the case of going out without WIFI, plug in the U disk, you can come to a visual feast. For those students who are rehearsing shows abroad, there is also a great advantage. You can put down the small screen of your mobile phone and follow the 100-inch projection screen.
The manufacturer placed a battery in the remote controller intimately, using the remote control to switch, volume adjustment and other operations, but when using the vivo Xplay5 mobile phone for Android with the screen, the remote control can not control, only in the U disk mode Can be controlled with a remote controller.
Experience articles: mobile second changes 100 inch TV
After the boot, the screen will display the U disk mode, the same screen mode of operation tutorial, and in the upper right corner will show the remaining power of the projector, the author here with a 32-inch LCD TV and projection screen size comparison, did not expect The tiny projector really does 100-inch seconds.
Although projected on the resolution is slightly inferior, only the resolution of 854480, there will be a little grainy near the look, but also the phenomenon of non-uniform focus, but the overall is still clear, in the teaching of dark environment also has a good projection effect, after all Is such a compact projector, how can we do a harsh contrast with the hanging style?
I use the vivo Xplay5 mobile phone, open multi-screen interactive features on the phone, search for PaPa devices can be Android with the screen.
After the connection is successful, the operation on the mobile phone will be displayed on the imaging, but the author finds that the projector's response speed is slightly slower, and it feels that the mobile phone is not synchronized with the projection.
As a TV fan, I didn't have time to pursue dramas in high school. When I was in college, I came up with a bad debt. After I got projection, how could I not come to a few episodes? The 5.43-inch mobile phone screen suddenly turned into a 100-inch TV. My excitement was almost incomprehensible. However, the author finds that the effective distance between the mobile phone and the screen is relatively short, and if it exceeds 15cm, it will happen occasionally.
In addition, PaPa projector also supports U disk mode, we can put music, video, pictures and other resources into the U disk, through the projector for screening.
From now on regardless of where you are, whether or not there is a network, as long as you bring U disk and PaPa, where will be your movie theater, and even can play while watching the phone, how can a cool word too?
At a large party with music, with a projector to show the United States and the United States photos, that atmosphere can be driven at any time by you Oh!
If you want to declare, ask for marriage, it is estimated that this can also be your stepping stone to help you.
With so much time, how much heat does the projector have? The author's test, before use, the projector lens temperature is about 31 °C (close to the room temperature of 32 °C), after using for an hour, the lens temperature is about 42 °C, there is a clear sense of hot, although both sides are Cooling holes, but it can be seen that the cooling effect of the PaPa mobile projector is general.
In the case of a fully charged, unconnected power supply and a 3/4 volume, the mobile phone is connected to play the movie. After about 80 minutes, the projector will automatically shut down after printing. If you're a TV fan like me, watching a few episodes of television shows, remember to use an external power supply and use the projector.
Summary article: small and exquisite but slightly expensive
As a happy girl with a 10-dollar DIY projector, I'm quite happy with the PaPa-based mobile projector. Here's a brief summary.
advantage:
1, small and exquisite, easy to carry.
2, supports a variety of connection methods, can be used in a variety of different scenarios.
3, the actual projection size is larger, the projection effect is good.
Disadvantages:
1, the same screen effective distance is shorter, the response speed is slightly slower.
2, heat dissipation is not ideal.
3, no tilt adjustment, uneven focus.
I feel that although the PaPa projector's compact and portable bring us a lot of convenience, but the price of nearly 2000RMB is still slightly expensive, but such a compact projector is expected to set off an upsurge in the market, so the price is set It seems to be understandable again. After all, we must drive a wave of trends. What do you think?
