Hey is a guy who likes to drum up some gadgets, especially when the soft sister lacks enough money and he/she itches some tall stuff, he will find some alternatives YY (Ah Q mentality ). In the case of home projectors, I have always had ideas, can suffer from unacceptable conditions at home, and I have little knowledge of this knowledge. Although I have learned a bit from the major technical forums, I don’t quite understand it. , With speakers, amplifiers, pick the right projector is a little dizzy food. Never understand the hardware but blindly pursue performance.
), slowly transforming, hoping to have a suitable Dongdong. In fact, in the final analysis, do you want to play fresh?
A while back, I saw that someone was playing a mini-projector on the Internet, and I happened to encounter XX insurance to send a micro-projector to our BOSS. All of a sudden, the excitement was ignited. This is not tossing the Internet. Go on such a little guy to come back!

Power interface 
VGA interface 
HDMI interface, SD interface and mobile power interface, the bottom is to adjust the projector screen trapezoidal correction knob. 
I stole a lazy one and found two pictures for everyone to look at from the Internet. It's easy to understand ~~
The actual connection is like this
After starting up, you can see the LED lights in front of you
OK, now please ignore my bed, because my family currently has a suitable white wall in my room, so I had to put it on the bed, and I directly dropped it on the white wall of my bedroom. .
Select your signal source on the machine, here I first tried both SD card and USB
The interface after booting is like this, it is very simple, can use the projector's button and the remote controller all can operate, very simple. Basically, it is divided into three options: movie, music, photo and text. 
First of all, I first test the text. Here is a TXT file of Zhu Xian. The result shows that the handwriting is still relatively clear, but there are some fonts that are garbled. This problem should be caused by insufficient support for text. , but I think no one should be bored to read the novel with projection? ? ?
Next, test the picture.
The following picture is taken with a micro shot in a full dark environment. The photo was taken by me on the seashore of Xiamen last month. The resolution is about or so. It can be seen that the resolution of this UNIC Youliku UC30 is slightly different. A little worse, obviously feel that the picture is not fine enough, but on the whole it can still be seen.
When you look at the picture, the machine will automatically play the picture. It takes about five seconds to automatically change the picture, which is more convenient for friends looking at pictures.
Next is the highlight of the machine test, video playback test, the size of the picture I put on the wall is about 50 inches up and down, then there is a bit fuzzy on the big, it is estimated that this is the limit, unlike Taobao profiteers say can cast 100 inches .
Here I use several of the most common formats to play videos, including the 1080 MKV "Tiaomu Taiwan" and "Princess Phantom", the RMVB "The Girls We Followed", and the AVI format. Cape No. 7
"Tiaotou Taiwan" and "The Girls We Followed in Those Years" were tested by COPY to SD Card.
The RMVB format "The Girls We Followed in Those Years" was very loud !
Here I want to explain is that I do not know why the high-definition video MKV format will appear to see the screen, but it can not afford to blame the strange problem, asked the seller said that this is not possible, but I do No sound . Currently still looking for the reasons, the initial judgment is the reason of multi-channel, but this UNIC You can UC30 UC30 is unable to switch channels, if you know a friend please inform, thank you!
After testing the SD card, I found a U disk to try it out. Actually, this small projector also has a sound, but it can also adjust its own size, but I feel the sound is not good, so I added a small speaker on the side of the Lang Qin.
The "Princess Phantom" in MKV format still has no sound, but the picture is really good.
CAP format "Cape No. 7" 
Intruding into the "Let the bullets fly", the format is MKV, but there is a voice ... I have Yun Cai, what the situation is I must study it!
The UCC Unicom UC30 also has a very outstanding advantage, that is, it can use mobile power, which is really creative, which allows us to camp in the wild when there is a good choice. Imagine that when you were in the wild night, when the screens were on the ground, come up with a UNIC Yucai UC30 and put on a wonderful movie. It was definitely able to win a full house!
The point here is to remind that when using a mobile power supply, the brightness will be reduced, but in the dark environment, this brightness should be enough, at least I do not feel there is any problem. 
Finally, let's take a short video of my record. Shoot it with a mobile phone. Please don't beat the bricks if the light is bad!
advantage:
1, small, portable, very easy to enjoy audio and video life.
2, low prices, buy such a small thing to come back, not bad, but also feel bad.
3, rich interface, can adapt to all kinds of interfaces, you can connect a variety of devices (mobile phones, computers, IPAD, etc.).
4, can be powered by mobile power, and instantly expand its scope of use, absolutely tall!
Disadvantages:
1, the resolution is not high, see high-definition film source and ordinary film source in this small machine can not be too much difference.
2, the heat is not small, although the cooling fan desperately blowing, can be used for an hour or so is still very hot.
3, can not replace the professional projection equipment, can only be used as primary entertainment
Conclusion:
What kind of projector is selected? That is really a problem for radish greens. Which place does the budget buy? As a person like me who likes to go outdoors to play in the open air, there aren’t any great projectors at home. This UNIC Youke UC30 is really suitable for me to play. You can't use such a professional eye to look at this "little guy". After all, it is just a toy that adds little pleasure to us. What professional things to talk about after that, you say, right?
All in all, although the advantages and disadvantages are as obvious, you can get a very interesting miniature projector with a price of around 380, and the appearance is not too ugly, the functions are complete, and the operation is simple. I say it is worth buying.
At the end of the last minute, remember that it is a gadget. Do not look at it with the money of cabbage to buy a steak. This is not true. !
The first time such a serious drying thing, there must be a bad place to write, and a lot of things are not professional, after all, I am just an ordinary player, I hope you all give encouragement, there are insufficient places to ask you more criticism, but also thank you stand by!
