Getting Started Building a DIY Projector

Okay. So now that you have decided to add a DIY video projector to your home theater, what next? Don't worry - it's easier than you might think. Take a deep breath, and prepare for a 10 minute read.

The first thing you'll need to do is simply to assess what tools you have. My motto is "the more, the merrier", but a DIY projector is actually very simple to build, so you won't need much. There are basically two paths that you can take depending upon your tool situation: 1) Build everything from scratch or 2) purchase ready-to-assemble parts from the DIY Projector Company. Either way is fine, but you'll probably save a little money if you've got the tools and skills to make some very simple cuts in half-inch composite wood.

I own a hammer and some screwdrivers, is that sufficient?

Sure - even if you're not Mr. (or Mrs.) Handy, you'll still be able to build a DIY projector just fine. You definitely will need a couple of screwdrivers, which you could purchase for less than $10 if you don't already have some. It is also a good idea to have a drill with a few small-medium sized bits, but this isn't absolutely necessary.

In addition to the parts that you would normally need to acquire, you will also want to purchase a projector enclosure kit from our online store. This package deal includes panels of MDF composite material that you will assemble to make up your projector housing. Normally that requires an inexpensive drill and screwdriver, but if you don't have a drill then you can request to have the enclosure drilled ahead of time for a small fee.

I've got more tools than the average contractor, give me some wood to cut!

If you have a power saw and some of the essential hand tools, then you're good to go for building your projector from scratch. You'll need a sheet of 0.5" MDF board or some plywood. These materials are heavier than necessary, but allow for a very simple construction without the use of any unusual fasteners. The instructions for cutting your materials to make your own enclosure are found within the normal instructions here.

Okay, so I have my projector housing figured out, what next?

Now that you have your projector housing planned out, it's time to get the rest of your projector goods together before you can build your video projector. The instructions and design notes for each projector design offered at the DIY Projector Company can be found here. In this section, you will also find a list of necessary items for each projector design. In general, every DIY projector needs an overhead projector style fresnel lens, a projection lens (a "triplet" is recommended), a light source, and an LCD panel. There are plenty of variations on each of the designs out there, but the same basic items are required for each projector. Many items are available elsewhere on the net in such places as eBay, but you will probably find that it is both more convenient and a lot cheaper to purchase from our online projector equipment store.

That's all . . . surprised? It only took 5-10 minutes of reading and now you're prepared to go build your projector! Once you have all of the parts necessary, it should only take you about an hour to build the projector initially, but expect to spend more time calibrating it until your complete satisfied that you have the best image possible. Depending upon where you purchase the parts required and what parts you may already have, a typical DIY projector cost between $300-500, though some have been made for less, and some have certainly been made for more.

Projection Theory
How and Why LCD Projectors Work

A DIY Projector uses a small, bright, white light source, a transmissive LCD panel, and a large format objective lens to project a motion image from your DVD player, video game console, or cable box onto a projection screen. Image sizes range to nearly every end of the spectrum starting at about 40" and stretching to a typical 100" diagonal screen size, though technically you can go to an infinitely large projection size.
How a DIY Projector Works
Every LCD Projector follows a basic design. That is, all LCD Projectors must have at least a few basic components:

Light Source
Fresnel Lens
LCD Panel
Projection Lens
The diagram to the right shows this generic setup. The key to building a quality projector is to use the best quality components. If any one of these four basic components is of poor quality, the overall quality of your projection will suffer as well.
In a typical LCD projector, a fresnel lens pushes rays of light from a bright light source, through an LCD panel and onto the back of an objective lens (also termed a "projection lens"). The projection lens then focuses the image of the LCD panel onto your wall or projection screen at magnification.
Improving Quality
Here is the main focus of nearly every DIY projector website - how do I improve the quality of my projector? The answer is both simple and complex at the same time. First, the simple stuff. In the most basic terms possible:
Use high quality optics (projection lens) for a high quality reproduction of your image.
A brighter light source = a brighter projection.
The higher quality your LCD is, the more realistic your projection will appear.
Those are the "easy" ways to improve quality. In fact, you can get some of the best lighting and lenses right here at DIY Labs in our parts store to get the best quality possible from your projector. Other enhancements and the reasons why certain types of parts (especially light sources) work better than others, take a look at the other theory pages.
Advanced Design For More Efficient Projectors
Though the above basic design works well, there are many places for improvement. The most basic way to improve this design is to add mirrors between the light source and fresnel lens so that the light isn't shooting in a straight line anymore. This is known as building a "folded enclosure". By doing so, the projector becomes much shorter, though a little bit wider. Overall, the volume of the projector is decreased significantly. The same enhancement can be made between the LCD and projection lens for even more space savings. While either one of these mirrors will greatly decrease the size of the projector, adding the second mirror often doesn't save as much space.
Other enhancements include the use of special combinations of particular light sources, LCDs, and lenses so that even more mirrors can be used. In a modern OTC ("Over The Counter") projector, the light is often "folded" by as many as 3 mirrors before striking the LCD it was meant for. But this is only possible by using smaller LCD panels and very precise reflectors. Our level of precision isn't that high, which is why DIY projectors remain larger than nearly all OTC projectors.

DIY Projector 101
For home theater enthusiasts, film fanatics, or any guy in search of a new gadget, a big screen video projector is a must have. The only problem is that they cost a fortune to buy and operate, right? Not anymore . . . enter the DIY (Do It Yourself) projector by the DIY Projector Company..

A DIY projector is an affordable alternative to professional LCD projectors with costly replacement lamps or an expensive rear projection television that takes up often-valuable floor space. More importantly, it is a worth-while project that will give you a profound sense of accomplishment and is sure to impress friends and family!

Building one of these projectors is relatively easy, and requires virtually no skills prior to making one. A typical DIY projector is comparable to an 500-1000 lumens projector as far as brightness, and is completely on par as far as clarity and sharpness go. And the best part? A DIY projector costs between $300-500. Just a lamp replacement for a professional projector can cost even more than a complete DIY projector!

So if you want to be able to present movies, ball games, or play video games on your own big screen TV, read more and consider building a DIY projector. All of the plans, notes, and instructions can be found here at the DIY Projector Company for free. We also carry all of the necessary parts at great low prices, and also offer free tech support and consulting via email - even if you're not a customer!

正在设计第二代 投影仪,使用8.4寸,或7寸的液晶屏,

其实lcd先天的透光性就不好,作出来的成品用再好的屏幕也和dlp投影不能比,

但是家庭,20 30平的卧室看,已经很可以了,效果刚刚满足2~3人。

如果是7寸的可以做到400* 300*120的体积,那就和一个公放的体积差不多了,

还打算把我以前剩下的笔记本cpu的风扇加进去,可以增加散热,减少噪音。

近期打算做个8寸屏的,有兴趣的朋友一起探讨,主要是光源利用率问题,怎么能达到最大

没想到在这里找到有相同爱好的,我做的和小黑唯一的关系是用它上网找的资料。
我是买的成品机箱做的,和你作的差不多,全铁外壳,散热好,但比较重。我用的是150W/12V普通灯泡,用的计算机电源,9.4“(?)日立LCD屏,可以调节亮度,对比度之类的,很好用。

楼主的菲涅尔透镜是在哪买的?我现在用的透光率不好,还不平,焦距也有点小。镜头可能也有些问题,整屏调好焦后,有一斜条聚焦不是很好,从文字上能看出来,估计是镜头里面的镜片移位了,镜头摔过,买了一些镜片,准备diy一个镜头。

效果很好,与LP特意到商店比了比,除了亮度低,不能在白天看之外,颜色,对比度都差不多,性价比高很多。我还买了红叶的珠屏,自己改成电动的。现在LP已经拒绝用29寸SONY(2000年花9千多买的)看大片了,要看就是投影。

镜头我还没有研究明白,

但是你的灯源不行,一般的 普通灯泡的色温不够,最基本的显示白颜色的时候,发黄,最少的也得用250w的10000k的,

我用的是普通照明用的,最近看到网上有投影专用的,双端金卤灯,但是是6500k的,说是效果比10000k的还好不少,下一代打算用这个

还没告诉我菲涅尔透镜是在哪买的?
我用的灯泡是胶片投影机的灯泡,色温还可以,主要是便宜,双端金卤灯和整流器太贵。现在发现灯底下有一些金属,估计是灯丝蒸发出来的。
