Additional changes (2014-10-31 10:21:40):
Add measured data, in the case of 16:9:
1.5 meters from the wall, projection screen length and width 1300750 mm, equivalent to about 55 inches (55 inches projection, length and width 1328747 mm)
2 meters from the wall, projecting a screen width of mm, which is equivalent to about 90 inches (90 inches projection, length and width mm)
For the time being, I haven't practiced the skills of measuring projection to ceiling. . .
From a number of 2K yuan level micro-projection, this machine was chosen. If you have already given up on micro-projection (low resolution, low lumens), this machine may not meet your appetite; if your budget is over 3,000, then this machine may not be suitable for you.
The target customers of this machine should be those who have relatively strong portable requirements (can not use it), such as visiting customers (business negotiation, business trip training), outdoor camping or expansion, and can also meet small-sized households (renters, student dormitories), Especially single people.
Several core parameters of this product are as follows:
Brushed metal surface, 200 lumens, 1280 resolution (officially 800600, but after the boot is seen in the system is 1280), 6300 mAh built-in lithium battery.
Input port: HDMI (accessible HDMI cable, MHL cable, HDMI wireless adapter)
No built-in system, no wifi, no Bluetooth, no support for U disk playback, does not support the insertion of memory card playback
The shape is smaller than imagined, and the surface metal brushing is just right (not to mention how luxurious it is, but it looks pleasing to the eye than ordinary plastic). It is more neutral and suitable for men and women.
Pull-out lens cover design is very heart.
On the edge of the lens is a fine tuning button to adjust the sharpness
There is a screw hole on the back of the machine, which can be connected to a tripod. When it is used for home projection, especially when it is dropped on the ceiling, it must be equipped with a tripod. (All ports are in the back of the fuselage, it is not possible to place it vertically.) It is recommended that this screw hole should not be opened directly on the machine. If it is used for a long time, it may slip, so this gadget is best done by snapping (similar to Philips' model), screw holes open on fasteners (can send one more fastener at random)
The operation interface is simple and clear, mainly including the volume, brightness, contrast, projection mode, language and other settings, relying on a few buttons on the box to get everything (no, no remote control). The use of the button feels so careless, it is recommended that the icon on the button can borrow from Android phones (home page, return, etc.), so that the use of keys is known at a glance.
The sound of the machine is a bit better than it should be. If you usually use a laptop with a speaker, the difference is not particularly great. If you usually use the speaker, you can directly insert the speaker on the micro-cast, or insert the pen, and then change the audio output settings (even if the Asus computer, change the output device is very convenient, the default is S1 audio output, in the lower right corner Change to notebook speakers.
But if it is a Bluetooth speaker. . . Because there is no such thing as a high-end thing, I don't know whether it will change or look good. . . I guess it should be changed to laptop output for Bluetooth playback
Compared to those Android smart micro projectors, the biggest drawback of this machine is that it does not have WIFI, there is no Bluetooth, it does not support U disk and memory card, the only input port is HDMI, if you want to connect the phone, Android machine can use MHL line ( Random accessories), Apple will be equipped with an additional HDMI wireless adapter (JD 200-500 yuan range) to achieve airplay push. The next version is suggested, and a wireless adapter can be included with it. After all, it is the mobile internet era.
From left to right, the order is: audio output, HDMI input (MHL input), USB charging output, power input, and key.
Accessories include: standard HDMI line 1, HDMI to micro USB MHL line 1 (connected to mobile phones), micro USB line 1 (for mobile phone charging), micro-transmission holster 1, micro-projection carrying case 1.
The accessories are quite complete, and those lines are estimated to be sent by other brands, but the final leather case and carrying case give people a sense of satisfaction on the scene. They are very considerate and hope to maintain the next version.
Photographs of photos taken during the day were specially sun-dried, and the effect was acceptable after the curtains were pulled. In the evening, cast on the ceiling, the effect is leveraged.
The higher the throwing distance requirement is, the shorter focal length is actually negligible. Measured from the wall about 1-1.5 meters from the projection effect, the most reliable.
If your room is less than 10 square meters, you still have to drop it on the ceiling. Whether it's wall or ceiling, floor tripods are the most reliable.
Before comparing the other four micro-projections, namely Philips PPX2055, Acer C205, Haier commander, Tencent Q video, the following will make simple comparison of the advantages and disadvantages of the first two paragraphs. Haier Commander and Tencent Q Shadow were the first to be eliminated due to strange shapes.
Philips PPX2055
Advantages: The machine is small, slightly larger than a pack of cigarettes. Universal USB port that can both charge and transfer images. Buy it now and send it to the desktop and a tripod.
Disadvantages: 55 lumens, small pitiful. With only one USB port, there is doubt about the versatility of the accessories and at the same time there is no certainty about the effect of the projection. The price is not high.
The same price, is the least function, of course, the operation is the most fool.
Acer C205
Advantages: built-in speaker, HDMI cable directly with the picture with the sound output, to solve the phone's sound is small. Lumen 200, can receive.
Disadvantages: There is no wireless connectivity, you need to purchase an HDMI wireless adapter. Although small (140108mm), it is not as small as the others.
One of the earliest concerns and purchase desires, the style is more conservative (individuals do not like strange shapes). At present, Jingdong quotes 2399, Central Asia 1999, suggesting that there is an idea to go to Central Asia.
=====================~~~~~~~~~ Gorgeous comprehensive assessment split line ~~~~~========== ==================
Summary: This section is a comparison of several brands of my price of about two thousand micro-cast, a comprehensive comparison, I feel the best performance of a paragraph.
The reason why I did not choose the smart micro-projection system that comes with the Android system (Haier Commander, Tencent Q film) is mainly because I feel that it is not very useful, and the other models have a lumen below 100. The Acer C205 is the ultimate PK with the Asus S1. It can be said that they are comparable, but it is ultimately lost in appearance (C205 is plastic, S1 is metal wire drawing) and size (C205 140108mm, S1 102110.5 mm) and others. Several are unmatched - the abundance of accessories.
The main purpose of my micro-investment purchase is to watch movies and TV dramas on a daily basis, and occasionally bring friends out to party. The projection effects (brightness and sharpness) are the primary considerations, so sacrifice a bit of versatility (such as inserting U disk and memory card) is also Can receive.
ASUS S1
Advantages: compact appearance, workmanship is acceptable, good projection effect, built-in 6300 mAh lithium battery measured life 3.5 hours (volume 6, brightness and contrast are 5), complete accessories.
Disadvantages: Does not support U disk and memory card playback, if you want to connect Apple devices to achieve airplay but also to purchase separately HDMI wireless adapter
At present this machine is in Jingdong, Amazon are 1999, in Beijing, there is a single ritual activities in the sun, after the sun single gift box millet, as of October 31, if there is a recent purchase plan is not particularly urgent, you can see Double 11 has no better price.
Finally Tucao, this machine's carton outsourcing box is too frustrated, crumpled, just like a long time inventory.
