New projectors deserve new screens--go instant!
The Long and Short of Projectors
A digital projector is a great way to present a lesson for the whole class to see, but small and oddly shaped rooms aren’t projector-friendly. Toshiba’s TDP-EW25U is the first of a new breed of classroom projectors with an advanced short-throw lens that can work at less than two feet from a screen, transforming any room into a digital classroom. At around $2,000, the TDP-EW25U may not be the cheapest projector, but it can work in tight places.
Inside the projector are a 0.65-inch DLP imaging engine and a sophisticated lens that team up to create a sharp 1,280 by 800 widescreen image. It can fill a 10-foot classroom screen from five feet away or a 3.5-foot screen from just 22 inches. Because the projector sits so near the screen, there’s less chance of casting shadows when working in front of the screen—a real bonus for teachers. The TDP-EW25U also has wired Ethernet and an 802.11g Wi-Fi radio built in.
On the downside, when you factor in the cost of electricity and the costly replacement lamp, the projector’s expenses come to a hefty 26 cents per hour. Still, for classrooms that aren’t long on space, this projector might be the best choice.

Schools looking to incorporate student-made videos into the classroom or a Web site should check out the SupaCam DVi. This small and light digital camcorder sells for only $328, a fraction of what similar devices go for. On top of 12-megapixel still images, SupaCam DVi can capture high-definition video at 30 frames a second. Rather than tapes or DVDs, SupaCam puts it all on reusable SD flash memory cards. Just record the material, remove the card, and plug it right into a computer for immediate editing and distribution; an inexpensive 2GB card can hold more than five hours of raw video.
Hear Me …
Schools that lack a public address system can get the word out
by piggybacking PA announcements over their data network with Cyberdata’s VOIP technology. Cyberdata has everything a school needs, including paging gateways, amplifiers, servers, and speakers, and the company’s Web site has a handy interactive calculator for deciding how many speakers a school needs.
The Computer that Saves
The ThinkCentre A61e from Lenovo not only is quieter and smaller than a traditional desktop PC, but it also uses 50 percent less energy. The savings can add up quickly; Lenovo estimates that the typical school can cut its electric bill by about $20 a year for every PC it replaces with an A61e. Based on either an AMD Sempron or Athlon Dual Core processor, the A61e starts at $400 and can be ordered with Windows XP or Vista.
Up, Down, Here & There

Download a Cup of MoCA
Be on the lookout for MoCA, but you don’t have to spike your morning coffee with chocolate. MoCA stands for the Multimedia over Coax Alliance, and it could be the next big thing in networking. By sending data over the plain old coaxial TV cables that most schools already have installed, a MoCA network can be cheaper than traditional Ethernet networking, and with a top speed of 110 megabits per second, it’s just as fast. Look for a slew of MoCA products from DLink, Linksys, and Toshiba.
The Big Picture
Widescreen projectors have traditionally been too high-end for most classrooms, but the new EIKI LC-WB40N widescreen classroom projector (premiering at FETC 2008) now comes in under $3,000. Since it weighs less than 10 pounds, it’s easy enough to share between classrooms and auditoriums. Other bells and whistles include wired and wireless network connectivity, analog computer input and monitor output connections, and DVI with HDCP supporting both digital computer and video input.
Why install a permanent projector screen in your school’s auditorium if you only use it a few times a year? Airscreen is an inflatable projection screen that can be erected in a few minutes and folds for storage. Available in either traditional 4:3 or widescreen 16:9 aspect ratios and from 16- to 30-foot sizes, the screens can even be used outdoors for movie night or other activities. Several schools, including Burning Tree Elementary in Maryland, have used Airscreen. Pricing starts at $5,000.
