Using Projectors For Museum Displays and Other Creative Presentations


Visuals are important to the learning process. Consequently, most educational institutions now use projectors as teaching aids. Learning recreational facilities such as museums, zoos, planetariums and aquariums can also benefit from the use of projectors. This is especially true when it comes to setting up displays and exhibits.

You’ll want to make sure that your presenting images are clear and easy to view. To do this, you’ll need to purchase the right projector for your specific needs.

Brightness
Lighting often varies in museums and aquariums. Therefore, it’s important to choose a projector that can work in rooms that are really dark or saturated with light. To ensure good images in all types of lighting, you should choose a projector with a minimum of 3000 lumens. A projector with 3000 lumens or more can also work for outdoor presentations.


Lightweight
Portability is also important. Choose a projector that is both small and lightweight so that you can easily move it from room to room. You may consider choosing a larger projector if the device will be mounted in an auditorium or other permanent exhibit area.

A Short Throw Lens
Next, look for a projector with a built-in short throw lens. This is an important feature to have while visitors walk in and out of exhibits or presentations at these facilities. A short throw lens will allow the projector to be really close to the screen without distorting the image. This will prevent people from walking between the screen and the projector and thus blocking the picture.

Connectivity
You’ll want to be able to connect your projector to other sources such as computers and DVD players. To ensure connectivity to other equipment, your projector should have video, audio and HDMI inputs.

Quiet Operation and Low Maintenance
Finally, make sure the projector you choose is quiet and will not disrupt the enjoyment of your exhibit. Other features including a long bulb life and no hassle set-up are important to consider as well.

HOW TO INSTALL A Tronfy TP-46 VIDEO PROJECTOR

You’ve finally stepped up and decided to take that next step into the home theater Big Boy club; you’ve made the decision to abandon that weak-sauce, girly-man flat panel display and go with a strong-like-bull front projector! First things first…bring it in. We gotta hug this thing out. Congratulations!
So, now that you’ve made this momentous decision you’re probably all, “What the hell? How do I turn this madness into a reality?Here’s everything you need to know about installing your new front projector! 

Screen Size
The only thing we’re interested in here is the screen size. And by size I mean the width, because it is the screen’s width that is going to determine the throw distance and installation location of the projector. For the sake of math simplicity, let’s just assume that you are going to use a screen that has a 100-inch width (which would be 115-inches diagonal and 56-inches high for a 16×9 screen).



Throw Distance
Throw distance refers to the distance from a projector’s lens to the screen – every projector has one. Fortunately, most modern projectors have a pretty install-friendly throw distance, enabling them to work in nearly any room with a large array of screen sizes.We suggest best Projection Distance: 1.5-2M; best Projection Size: 49 to 80 inches, which can make you obtain best User Experience





















Cabling
If you have a front projector, that will likely mean that you have a home theater system and some kind of surround sound receiver or pre-amp/processor. Really, you only need a single HDMi cable going to the projector as all of the video switching and conversion will be done in your receiver.




















Sound
For perfect sound, we recommend customer connect an external speaker . Via the 3.5 mm headphone jack, or via the 3-In-1 audio& video port.


Now, who’s hosting movie night first?

The difference between LCD and DLP projectors

                                                                                                                                                                                                                                                                                                                                                                          LCD stands for “liquid crystal display,” a term used to indicate that the unit contains two transparent polarized panels, with a liquid solution between them.

With LCD, light shines through the panels from behind, causing an image to appear. Polarized panels will only pass light waves in one plane, and the panels are positioned at a 90 degree angle to each other, which means light from one plane cannot pass through the other panel. But when electricity passes through the liquid crystals, individual pixels are switched on or off, to produce a specific image.

With regards to projectors, LCD projectors typically send light through a prism from a metal halide lamp that separates the light into colors (green, red and blue). The video signal is essentially split by color, and the prism sorts the colors and projects the specified image.

LCD projectors are the most popular because they are lightweight and extremely portable. Typically, metal lamps are used for their ideal color temperature and ability to display a large amount of colors. Additionally, metal lamps can produce a vast amount of light in a small area, making them ideal for high-lumen outputs.

DLP stands for Digital Light Processing. With a DLP projector, white light is projected through an array of movable mirrors that control the intensity of each pixel of light as well as the color.
DLP projectors generally feature brighter, more defined display outputs than LCD, but are certainly more costly. Many businesses and educational companies prefer DLP over LCD.

Although DLP projectors are more expensive, they hold a distinct advantage over LCD projectors with regards to maintenance. Projector maintenance and cleaning are required to keep each unit in good functioning order.

Every interaction with a projector ultimately costs time and money; therefore, it is important to understand how often you will need to maintain your projector throughout its lifetime. DLP projectors can save a bundle on time and money since no filter is required, and DLP projectors features a lamp free design.

Why I Choose This Soldering Iron to Do the Jobs?


Before that, I never thought I would use a soldering iron in my life. Cause I am a woman, soldering job is something a man should do, that’s my thought
One afternoon two months before, my son was in his musical electric toy car, driving here and there. Suddenly, music stopped. I don’t know what was wrong, and asked my neighbor for help. After a whole he figured out something is wrong with its circuit board. “I need do some soldering jobs” he said and brought out a pencil like thing, plug it to socket and it started to work. Just several minutes later, music sounded again. That’s so amazing.
At night, I started my computer and looked information for that magic pencil like thing in the Internet. It’s an electric solder iron, composed of soldering tips, soldering bar, inner heating core and a handle. And I got to know that an electric soldering iron is used for electronics and circuit board applications, covering wide range of devices such as radios, tvs, PCBs and many others.
All in all, every useful in life. So I decided to get one online. You know, I didn’t know it every much, comparing the price and function, I chose one at 15.99$ solder kit.

Several days later, the soldering gun arrived. Also asked the neighbor for help and borrowed a broken radio for him and started soldering with his help. It’s only an experiment. I did the job well, although his radio didn’t work at last. But I learnt how to use it.
During this process, I found I really love this kit for the following three reasons:
Since electronics circuit boards repair often involves working with delicate components, a handy, light weight and slim soldering iron always offers a good grip for holding and offers you great help.
Support for Multiple Solder Tips
Size of solder tip plays an important role in delivering the right amount of heat to the component being soldered. Interchangeable tips let you select the ideal tip shape for specialized work. Hence, check out for a soldering iron according to your need is quite vital.
Adjustable Soldering Temperature
200-450 degree Celsius is adjustable for different uses
Suitable for Most People to Use
Electronics soldering projects are not really handled by experts, but also can be hobby DIY projects undertaken by students and housewives like me. This one I bought is useful for all most people.

This is my first DIY soldering experience and the welding solder iron works fine for me so far. Really help my husband and me a lot.
