When you look at the heat, you use the headline “Get up and dry up your sleeves,†and one month’s time is at the time when I’m working and when I’m on the baby’s side. Closer to home. In September 15th, I bought a Z4x micrometer. It took more than a year, but overall it was also satisfactory. It was a matter of convenience. Even a power cord connected to a stand could be played on the table. The audio, set-top box, and connection were all available. A 100-inch curtain is hung on the wall (if it is a white wall, even if the curtain is saved), the effect in the dark light environment is still acceptable. There is no harm in the so-called comparison. Z4x has two hard disadvantages: First, the resolution is only 720p, 100 inch or a larger grainy. Second, the brightness of micro-projection is not enough, nominal 580asni, replaced with lumens 2000 (actual and practical certainly not reach, after the text will be said), I put the living room to open a circle downlight to make the picture clear, and color It is not rich enough. Especially after pushing the projection as a keyword in Zhang Da Ma, the idea of ​​switching to a light bulb became more and more intense. ………………………………………………………Dividing line………………………………………………………………… Finally, Aunt Zhang pushed the news of tw5300. domestic Limited Prime Member: Epson Epson EH-TW5300 Projector ¥ 3,090.61 + $ 463.59 including direct mail tax ($ 3554.2) Classic 3LCD, Full HD, recent good price.

In Central Asia, 3,500+ direct sales of tax-free direct mail were also purchased. Orders were placed on December 24 and shipped in the Netherlands on the 27th and received on January 9 for two weeks. Received projector, out of the box. The remote controller is in English, the power cord is British standard, some valuers are said to have received the power cord of the national standard, but also took out the Chinese menu, anyway, I can not, to the official website of a Chinese manual to adjust the menu The problem is not great. As for the specific evaluation, I wouldn't let it go. Aunt Zhang is a lot of people here, and I'm not likely to exceed it! Put a comparison with the polar meter Z4X on hand. ………………………………………………………Dividing line………………………………………………………………… Of course, the large size of the light bulb is not portable, and the large amount of heat causes the fan to sound, so it is best to lift it. In addition, even the stereo (with its own 3w speaker ignored) and the set-top box, once the projector is installed, it will not move, so we must plan and design. 1. Power supply The following figure is the final hoisting diagram. To lift the projector above the sofa, you must have a power supply. However, when the decoration did not consider projecting this file, so you have to pull a power supply. In order not to destroy the original decoration, to give up the plan to take the open line, we must think of ways to go dark. There is a downlight in the middle of the sofa wall. It is obviously not feasible to take down the electricity of the downlight. Fortunately, at the time of renovation, an acoustic cable was pulled through the ceiling from the TV background wall to the sofa wall. Therefore, the specific power cord routing scheme refers to the audio line, and the power cord is passed through the audio line pipe to suspend the ceiling and pass through the hole of the downlight to the center of the top of the sofa wall. The specific alignment is as follows: Use audio cables to pull wires to the ceiling. Connect to type 120 socket. Just cover the lamp hole. The other end of the wire is fitted with a plug, plugged into the socket, and the power is taken. 2. Projection bracket Since the living room has ceilings, it is obviously unsafe to hang the projector hangers on the suspended ceilings, so it is best to hang them on the wall. Aunt Zhang had a post about the professionalism of the hanger, so she also did one. Home Theater Development Program Part II: Projector Installation Parameters Calculation and DIY Universal Ultra-stable Projection Rack 1 Background Introduction In the previous section of home theater development program I: Screen selection and related parameter calculation, the choice of curtain was introduced. , The determination of dimensions and calculation of related parameters, because the installation parameters of the projector and the rack have a lot to do with the curtain, at the same time, whether or not the installation conditions are also factors that need to be considered after selecting the projection money, so we decided to write this first. The calculation of the installation parameters of the second projector and the DIY Universal Stabilized Projection Rack" Note: The following calculations are for last532| Likes 792 Comments 303 Favourites 4k View Details Taobao found a store to buy raw materials Into my uncle's factory, the material was punched and assembled. After installation, it was found that the shelf was really thick, but since it was all stuck with screws, it was estimated that it would not be easy to adjust after installation. So after trying a hanger that was idle at home, the result was this: The hanger is very flexible and convenient to adjust the angle of the projector. Unfortunately, if it is not installed on the wall, it needs to be equipped with an extension tube. Once it is installed on the wall, the adjustment of the up and down direction is very difficult, so I will use the above two hangers. Combine it, taking into account fine-tuning and firmness. 3. Installation After the projection of the lifting is basically not moving, it is not easy to move. Therefore, you must set the position before installation. The distance between the two walls of the living room is 425cm. Excluding the length of the screen and the projection, it can still be about 380cm. According to the projection size in the manual, the distance can be 120-inch. I bought a 120-inch glass fiber screen on the Internet. Since the logistics was mentioned, it was really long. There was much more from the rear of the car to the front of the car. Continue to count. Draw a sketch yourself and calculate some data for the background wall. Height 256cm from floor to ceiling The curtain is 149cm high The bottom of the curtain is 80cm above the ground, so the length of the top of the screen from the ceiling is: 256-149-80=27cm. Combined with the following table, it can be seen that the distance from the ceiling of the projection lens to the ceiling is just to be thrown on the screen at this distance: 27+14=41cm After setting various distances, start the installation. The curtain should be installed in this area of ​​the background wall. The height should be as high as possible, set a distance, and start construction. To the colleague's home borrowed a laser spirit level fixed point, punched the hook, curtain wall. Set the center point of the projector lens according to the center position of the curtain. The hanger should be 55mm to the right (see the figure below). Adjust the height of the ceiling so that the center of the lens is 41cm from the ceiling. Use a spirit level to straighten the hanger. The expansion screws used to hold the hangers were found for a long time and they couldn't find the exposed pipes so long. They were later found on Taobao. Use the hdmi cable to connect the enhanced version of Lynx Box 3, which is directly glued to the hanger to save space. Open the debug screen, fine tune the projection position and tighten the screws. The final product is like this. Still relatively clean and refreshing. What about sound? The speaker is placed under the curtain, and a Bluetooth adapter is connected to the Bluetooth of the millet box. It becomes a Bluetooth speaker, and you can use less cloth. After all the installed effects, the power cord is not exposed, and no wiring is provided from the wall to other areas, ensuring the refreshment of the living room. Finally come to feel the 120-inch effect.
