Bought this in a hurry 14 months ago. Over 2000 hours on the lamp so far.
Great picture for nightly movies with dinner. Foreign films, comedy, everything plays well for a family of film buffs. Easy size adjust for various aspect ratios. Lacks focus control on remote, but fine for our ceiling mount.

I bought this a year ago and have been using this projector as a primary display for my computer. Bright beautiful colors and works great for full screen gaming. Generally use this at 1280X960 but 1920X1080 is great for movies when I dont need to read tiny letters on the screen. I would purchase this again if it had not been replaced by better models. I will purchase Acer again for the quality.

I ordered this firewire pci card to edit video for my canon zr960. There was no cd driver to install on your computer and the pci card itself is just a plug in. Best Buy wanted to charge me $50 to install the card so I looked on youtube for "firewire pci card installation" and saw how easy it was to just take the cover off and plug it into the slot so I saved some money. Works just fine and the Texas Instruments Chipset for better sound quality is another perk!

Average Reviews:

(More customer reviews)
I buy these for work and we have them running 24/7. They last for about 15 months with the original factory bulb, but when the bulb burns out, we've replaced it with a new bulb and the picture is very dim, pretty much not usable. Remember, we use it 24/7 so this may not affect your application and it lasted over a year...

An ideal choice for business, large classrooms and conference rooms, Vivitek D940VX projector is an indispensable tool for watching educational videos, presentations, and more. With integrated BrilliantColor technology, high brightness capabilities, full PC connectivity and compatibility, and a powerful, high-efficiency lamp, this easy-to-operate DLP projector is designed to provide outstanding HD picture quality at an affordable price.
High-Efficiency Lamp for Super Bright Images At the heart of D940VX projector is a new-generation, high-efficiency lamp that produces a super bright image with 4,300 ANSI lumens and that lasts up to 3,000 hours in eco-mode. The projector also offers a full 2400:1 luminosity contrast ratio for crisp, rich, and accurate color details with every projection. This means that whether you keep the lights on or off, the D940VX will deliver a crisp image with deeper blacks and richer details.
For movie watching, the D940VX also supports 3:2/2:2 pull down, which effectively translates the images from movies in their original form to the screen without jagged images and ensures a clean, crisp image quality.
And for convenience, when it's time to replace the lamp, a convenient sliding top cover gives you quick and easy access.
Durable Low-Maintenance Design Designed for a wide variety of uses, including home, classroom, conference room, and workplace environments, the D940VX offers a durable, low-maintenance design that keeps your costs of operating down and lets you focus on your work.
The projector's engine is constructed with all-metal components, which makes it far more durable than similar projectors that rely on plastic components. The engine is also sealed, keeping dust away without relying on filters. This filter-free design increases overall durability and requires less maintenance. The projector also has a high altitude mode that lets it perform in low air pressure / high altitude areas, such as locations above 1,600 meters above sea level.
Vivitek projectors feature rapid startup and instant shutdown capability, so you can get started right away and get things done more quickly.
Stunning HD Picture Quality The D940VX offers 720p or 1080i HD resolution formats for quality video reproduction, while the native XGA 1024 x 768 resolution guarantees sharpness and clarity. The projector features Vivid Wheel III enhanced color reproduction technology to ensure eye-popping color no matter what the video input signal, and the integrated BrilliantColor technology features a five-segment color wheel (R,G,B,Y,W) for more natural-looking color and a brighter, more realistic picture. Thanks to its seven-color individual adjustment feature, the D940VX also lets you tune each color -- R, G, B, C, M, Y, and W -- for hue, saturation, and more.
With the D940VX, you can project images as small as 24 inches (diagonal) to 300 inches, giving you the versatility you need.
The Environmental Choice: Low Energy Usage and RoHS Compliant This compact projector is not only small at 13.2 x 4 x 10 inches (WxDxH) and 7.7 pounds, but it's also so quiet that you'll hardly even know that it's powered on. You'll save on energy costs as well, as this projector uses less than one watt of power in standby mode and as little as 290 watts during operation.
The projector offers an improved cooling feature, thanks to an innovative air flow design that draws air from a left-to-right direction, as opposed from the more traditional back to front. This results in more a efficient operation over the long term, as well as less wear on the motor.
Switch the D940VX to eco-mode for added lamp life, quieter operation, and even more economical operation. With a fan noise level of as little as 34 dB in eco-mode, you won't have to worry about a noisy projector drowning out your movie or presentation. You'll also be happy to know that the projector is RoHS compliant, meeting the industry's directive on the restriction of the use of certain hazardous substances. Constructed with lead-free solder and glass, and free of other hazardous materials, the D940VX is an excellent environmental choice.
Remotely Control the Projector Via the Web The D940VX also features a built-in web server and RJ45 connection that allows you to remotely control and administer the projector through a web interface. Simply connect the project to your network via the RJ45 connection and you can remotely control several of the projector's features and monitor the projector's status. You can have status reports on the projector sent to a network administrator via email, and you can also remotely control several functions, such as projection mode, brightness, contrast, and color temperature. You can also set the projector to power up or down on an appointed time schedule.
To ensure that you can use the D940VX in virtually any environment, it includes a full set of inputs, including HDMI and USB. It also includes a built-in three-watt mono speaker and outputs for an external speaker system.
For increased functionality in the home, office, or the classroom, the projector is also equipped with its own full-featured IR remote with laser pointer and mouse as well as a durable carrying case for protected portability. For added security, it also includes an extra anti-theft lock on the back of I/O panel, in addition to an anti-theft Kensington lock and software password.
The D940VX projector is backed by a three-year limited parts and labor warranty, a one-year lamp warranty, and a full five-year DLP chip warranty.
What's in the Box Projector, remote control (battery included), RGB cable, power cord, carrying case, lens cap, CD-ROM, and warranty card.
The D935VX is ideal for large classrooms and conference rooms.

Canon LS-154TG Handheld Calculator - made from the recycled materials of Canon copiers
Average Reviews:

(More customer reviews)
This review is for someone like myself that needs a basic calculator, with basic functions, that is easy to hold with one hand while writing with the other. Small enough to put in a shirt pocket, with a readout that doesn't require a magnifying glass and buttons that have a tactile feel (that eliminate false or repetitive inputs).
Pros:
1. Large readout
2. Twelve digits!
3. Dual power; Solar/Battery
4. Easy one hand operation
5. Readable operation figure; Add,Subtract,Mult,etc.
6. Fits in shirt pocket
7. Has protective lid for storage
8. Tactile buttons
9. Cost $8 bucks
Cons:
1. Owners manual is typical of a cheap calculator
(but if your not sure how to operate something this basic, you should be counting using your two hands and both shoes removed)
For $8 bucks and change, they designed and built this one right.

Ti-nspire Cas Software-teacher Review

Ti-nspire Cas Software-teacher
Average Reviews:

(More customer reviews)
The TI-Nspire CAS is an improved version of theTI-89 calculator. Like the TI-89 it has graphing and symbolic capability as well as the usual calculator functions. What is new in this calculator over the TI-89? The features that I have been able to identify and use are a definite improvement. One feature is that there are templates for most of the operations needed in calculus. These include integration, differentiation, limit, product, and others. The templates make it less likely that there are syntax errors in entering a calculation. The templates can also be used in programs as well as doing individual calculations.
It is possible to organize problems and documents on the TI-Nspire CAS. You can save work as documents. The documents have pages to organize the work into logical divisions. Your work can be saved and retrieved in an organized way. It is also possible to have more than one window displayed at a time. By this means you can monitor a graph as a parameter is changed or you can immediately see the effect of changing some part of a program.
The software version of the TI-Nspire CAS calculator is invaluable for those using the calculator in the classroom. Now you can bring a laptop to class with the software installed. By connecting the laptop to a projector, you can now teach the use of the calculator very effectively. The display is more detailed than projecting the calculator display. With the software version is also easier to write programs and do calculations since you have the computer keyboard and mouse.
Are there drawbacks? The TI-Nspire CAS is definitely intimidating. Once you have learned to navigate its many features, it is very powerful. However, without help, you will have trouble seeing how to do even some of the simple things that you may have in mind. As the calculator becomes more popular, this will not be the problem that it is now. Now, there is no one to turn to when you are frustrated.
As an example, I created some functions. They were examples to see how to create the functions and use them. When I was finished I wanted to delete them. But how do I delete them? Being familiar with the TI-89, I thought that the process would be similar. The familiar ways in the TI-89 did not work on the TI-Nspire CAS. Now that I have figured it out, it is simple enough. But finding the solution to this and other problems can be frustrating for the beginner. A human guide would be helpful and for most people essential.
How does the software compare with Maple and Mathematica? The TI-Nspire CAS software is limited, but has enough capability to be useful for classroom use.

I love how it shows you in "type" format what exactly you are typing into the calculator. That way, if I lost track of where I was in my checkbook, I would take a look at the last two entries and figure out where I was. And I have to say TI is all I've ever used since high school... It's good and dependable. If I hadn't lost the previous one, I would have continued to use it til it died (not likely in the near future) or broke.

Casio FX-300MS Plus 229-Function Scientific Calculator Review

Casio FX-300MS Plus 229-Function Scientific Calculator
Average Reviews:

(More customer reviews)
I used to own a TI-36 made by Texas Instruments. That was a nice calculator, but then I decided to upgrade to this calculator.
There are many differences that set this calculator apart from the TI-36.
First of all, I love the 2 line display that displays the equation or whatever you just typed in on the top line and the answer on the bottom. Makes a perfect alternative to a graphing calculator that is very similar by displaying whatever you originally typed in. The TI-36 did not offer this. THis is a big plus.
Also, whenever you need to indicate a negative value, you can either use the negative button or the minus button before the value... for example, if you wanted to enter -5, you just have to key in - 5. With a TI calculator, you have to key in the five first, and then the negative sign. The TI way used to cause me to make some errors, but the Casio way is very logical!
Finally, you can use this calculator in any lighting condition. Because of three way power, you can use the solar panel in bright conditions and battery power in dark conditions, all automatically without any user interference!
There are tons of calculations that you can do with this calculator.
Although this calculator may seem a little expensive for a scientific calculator, I highly recommend it! It is definitely worth the money!

Vivitek D930TX 3000 Lumen Short Throw XGA DLP Projector Review

Vivitek D930TX 3000 Lumen Short Throw XGA DLP Projector
Average Reviews:

(More customer reviews)
I originally purchased this Projector because I was hosting a Windows 7 Launch Party and wanted to be able to do presentations and demonstrate the OS. I wanted a projector that would be able to project an image that will be bright enough to see even though the lights are turned on.
This projector is AMAZINGLY bright at 3000 Lumens!! On top of that it has so many different inputs that it accepts just about any video signal. To get component video you need a RGB to SVGA adaptor, but those can be picked up for around $15 to $30.
The quality of this image is AMAZING!! I was able to project an image on my 35' Great room ceiling and it was still CLEAR!!! I am now using this projector in my home theater... it's NOT 1080P... but rather 720... but still "high definition" none-the-less.
This projector is PERFECT for presentations... HOWEVER... be aware that you can't really resize the image. The keystone only allows for a minor 15% correction angle. If you are projecting this on to a screen it's going to take a LONG time to get the picture size correct... as the picture size changes only by moving the projector.
I built my theater around this projector so for me it wasn't an issue. I mounted the projector then built the walls around it... used GOO for the screen... and it's totally amazing!!
Again, if you already have a home theater... this is probably NOT the projector for you. I would suggest getting a projector that can adjust the image size... but for the price of this I couldn't pass it up.
I went to Best Buy to compare Lumens... and the brightest that Best Buy had on display was only 1600 lumens... This bad boy is nearly twice as bright!! And the colors are AMAZINGLY vivid! The blacks are really dark... unlike almost all of the other projectors in this price range.
This projector is very quiet too... another huge plus when giving presentations (or watching tv/movie/PC videos).
Anyway, I HIGHLY recommend this projector. This is a very HIGH QUALITY product. I've been using this projector for well over 6 months now... often 3 to 6 hours a day... and the bulb is still extremely bright. I researched projectors that varied from $1,000 all the way up to $12,000... and I chose this projector because it gives about the same quality as a projector in the $8,000 range. The only downfall is the inability to adjust the video size (Did I mention that before??? YES... It's that important to keep mentioning)
Another nice thing about this projector which is AWESOME is that it only needs to be 4 Feet away from the wall/screen to project a 100 Inch Image!! That is HUGE!! My screen in my theater is about 10 Feet wide... and this projector is set back only about 5 feet or so... It's amazing!
When you're looking for a device to watch movies on... why pay much more for a 65" plasma TV when you can buy this projector and make a 65" plasma look TINY?? This is great value for the money... and I highly recommend this projector. I was a little weary of this at first because of the brand.... but Vivitek may be new to this market, but they are really putting out HIGH QUALITY projectors.
Because this is a short throw projector with a very bright bulb (3000 lumens) and amazing color output and a small price tag... I couldn't not recommend it.

It's also compact and lightweight, measuring just 13.2 x 4 x 10 inches (WxHxD) and weighing just 7.7 pounds. And being that it is designed for smaller spaces, its built-in cooling fan produces just 34 dB (Eco-Mode) for ultra-quiet operation that won't drown out the sound of your media.
The Environmental Choice: Low Energy Usage and RoHS Compliant You'll save on energy costs as well, as this projector draws less than one watt of power in standby mode.
The projector offers an improved cooling feature, thanks to an innovative air flow design that draws air from a left-to-right direction, as opposed from the more traditional back to front. This results in more a efficient operation over the long term, as well as less wear on the motor.
You'll also be happy to know that the projector is RoHS compliant, meeting the industry's directive on the restriction of the use of certain hazardous substances. Constructed with lead-free solder and glass, and free of other hazardous materials, the D930TX is an excellent environmental choice.
New Generation Lamp for Super High Brightness The heart and soul of any projector is in its lamp, and the D930TX features an innovative new lamp that generates 3,000 lumens for an ultra-bright picture in almost any lighting setting. The high brightness lamp makes this projector perfect for classrooms, small conference rooms, or home theater/gaming rooms.

There's even an HDMI input for watching stunning high-definition movies and programming at 1080i or 720p resolution. Thanks to its seven-color individual adjustment feature, the D930TX also lets you tune each color -- R, G, B, C, M, Y, and W -- for hue, saturation, and more.
Filter-Free Design for Increased Durability Unlike other projectors that need replacement filters to filter away harmful dust from its vital components, the D930TX features a filter-free design that keeps dust out without the need for expensive filters. This increases the overall durability and cost-of-ownership, not to mention lowering any maintenance costs associated with clogged filters or damage to interior parts. The projector also has a high altitude mode that lets it perform in low air pressure / high altitude areas, such as locations above 1,600 meters above sea level.
Network Connectivity for Added Versatility The D930TX also features a built-in web server and RJ45 connection that allows you to remotely control and administer the projector through a web interface. Simply connect the project to your network via the RJ45 connection and you can remotely control several of the projector's features and monitor the projector's status. You can have status reports on the projector sent to a network administrator via email, and you can also remotely control several functions, such as projection mode, brightness, contrast, and color temperature. You can also set the projector to power up or down on an appointed time schedule.
Along with all of the standard inputs, such as VGA, S-Video, Composite Video, and HDMI, the D930TX short-throw projector also has some advanced connectivity options, including RS-232C, and USB for added versatility.
Rounding out the D930TX's impressive set of features is an included remote control that also works as a laser pointer and functions as a mouse.

Casio(R) FX-9750GPlus Graphing Calculator Review

Casio(R) FX-9750GPlus Graphing Calculator
Average Reviews:

(More customer reviews)
I am a math teacher at a new private Bronx high school, and compared the TI-83 with the Casio in numerous regards before deciding which one our school would use. Hands down, the Casio wins, and it is cheaper as well. Note - I do not work for Casio or TI.
A) The calculator is more user friendly. The options are menu driven in a more intuitive way. What took me a minute or two to locate and figure out out the TI, took less than half the time on the Casio. Don't trust me- see for yourself.
B) The Casio is slightly faster than the TI
C)Features: The casio adds a dynamic graphing system (lets you change a coefficient and watch the graph change), which is very useful when teaching. I also like the EQUA feature, which lets my students calculate 2/3 equations, 2/3 unknowns, and solve quadratic or polynomial equations. Maybe the TI does this too, but I couln't figure it out.
D) The color thing I suppose is nice, but I use the CFX-9750, which is black and white and cheaper.
The only downside is that most colleges use the TI's, unfortunately. I liken it to most places using Microsoft when there are better alternatives out there (monopoly power). Anyway, a student who uses the Casio can do anything the TI-83 can do.
I'm a big fan, and my students seem to like it.
