DIY Smartboard….

datePosted on 12:33, January 3rd, 2010 by Many Ayromlou

Johnny Lee strikes again. The Wiimote Guru has a new project. Build your own expensive looking smartboard using a projector, laptop and a Wiimote. Excellent little project to kick off the new year.

Since the Wiimote can track sources of infrared (IR) light, you can track pens that have an IR led in the tip. By pointing a wiimote at a projection screen or LCD display, you can create very low-cost interactive whiteboards or tablet displays. Since the Wiimote can track upto 4 points, up to 4 pens can be used. It also works great with rear-projected displays.

Beagleboard is your friend…..

The USB-powered Beagle Board is a low-cost, fan-less single board computer utilizing Texas Instruments’ OMAP3530 application processor that unleashes laptop-like performance and expansion without the bulk, expense, or noise of typical desktop machines.

Beagle Board is based on an OMAP3530 application processor featuring an ARM® Cortex™-A8 running at up to 600MHz and delivering over 1,200 Dhrystone MIPS of performance via superscalar operation with highly accurate branch prediction and 256KB of L2 cache. Focal to Beagle Board experience is the high-speed USB 2.0 on-the-go (OTG) port that can be utilized to provide power to the board or to deliver highly flexible expansion. Standard PC peripherals can be connected to Beagle Board using the USB with a mini-A to standard-A cable adapter, DVI-D using an HDMI to DVI-D adapter, or through the MMC/SD/SDIO connector enabling a complete desktop experience. The picture below should give you a good idea of it’s size beside the tiny Pico Projector.

Hardware Specifications are as follows:

  • OMAP3530 applications processor featuring the ARM® Cortex™-A8
  • 128MB low-power DDR RAM
  • 256MB NAND flash
  • USB 2.0 high-speed on-the-go port
  • DVI-D output
  • NTSC/PAL TV via S-Video output
  • 6-in-one 8-bit MMC+/SD/SDIO connection
  • Stereo audio in/output
  • JTAG header
  • I2S, I2S, SPI, MMC/SD expansion header
  • Power via USB or alternate jack

Looks very nice and complete, a good alternative to Gumstix Avero stuff we covered earlier . And did I mention it’s only $149. Perfect for your next project.

Could this be the Google Tablet…..

Not too sure, but the Zoom OMAP34x-II Mobile Development Platform looks too “finished/flashy” to be a Mobile Development Platform (MDP). I guess time will tell……For now we can all drool over the pics….and btw, if you have $1150, you can beat the crowd and own one today.

Out of the box features of the Zoom OMAP34x-II MDP :

  • 4.1″ WVGA multi-touch display with a QWERTY keypad in a landscape, handheld form factor
  • High performance OMAP3430 applications processor that supports up to 720p HD video encode/decode
  • Support for popular leading mobile operating systems, including Android Mobile Platform, Linux, LiMo, Symbian OS and Microsoft(r) Windows(r) Mobile
  • Wireless connectivity technology from TI, including WiLinkTM 6.0 (WL1271), a single chip with Wi-Fi(r), Bluetooth(r) and FM functionality; and NaviLinkTM GPS functionality
  • 8-megapixel camera sensor
  • Optional 3G modem solution, as well as flexibility to support any third party modem through an extension card
  • An optional DLP Pico projection module will be available, taking mobile content from “tiny screen” viewing to a shareable “big screen” format
The DLP Pico projector is a interesting critter. It is literally tiny. The above picture gives you an idea of it’s size compared to the power adapter. You can pick one up for about $350 at Digi-Key.com ‘s online store. The tech specs for this little guy are:

  • Resolution: 0.17-inch HVGA (320×480 device creating a 640×480 projection)
  • Brightness: 7 lumens
  • Contrast ratio: 1000:1
  • Throw ratio: 1.89
  • Processor: MSP430 microcontroller with download port
  • Light source: Solid-state 3 LED
  • Video input: DVI-D 888RGB, VGA 60 Hz
  • Dimensions: 44.8 x 67.4 x 14.2 mm3

JVC does Super Hi-Vision

datePosted on 21:08, May 2nd, 2008 by Many Ayromlou

Yep, in the classic “mine is bigger than yours” fashion, JVC has once again upped the ante by introducing the worlds first single display device capable of 8K Super Hi-Vision. That’s 8192x432o pixels of joy AKA 35 bloody megapixels. We recently covered the introduction of JVC’s 4K D-ILA projector and well now the new game is called 8K.

Victor Company of Japan, Ltd. (JVC) announces a new addition to its lineup of proprietary D-ILA (Direct-Drive Image Light Amplifier) high-definition reflective liquid crystal devices for projectors. The newly developed 1.75-inch 8K4K D-ILA device has the world’s largest number of pixels and is able to display images of approximately 35 megapixels (8192 x 4320 pixels), the equivalent of more than 17 times the level of Full High-Definition. This means that a single display device can now produce Super Hi-Vision images and can display images with the highest number of pixels currently defined under international standards.

After JVC developed the initial 7.86-megapixel (3840 x 2048 pixels) 4K2K D-ILA device in the summer of 2003, it subsequently further evolved the technology for highly realistic, high-definition images through a range of test viewings and verification testing, resulting in the development of JVC’s first commercial 4K2K D-ILA device (1.7-inch device size, 5,000:1 device contrast ratio) and the 4K2K D-ILA projector incorporating that device in September 2004.

In June 2007 JVC developed a 1.27-inch 4K2K D-ILA device that was the world’s smallest device of its kind, having a 6.8µm pixel pitch and 4096 x 2400 pixels, and in February 2008 it began marketing a newly commercialized professional D-ILA projector, DLA-SH4K, incorporating that device.

Through the development of a new production process and new pixel structure for even finer pixels, JVC has now succeeded in developing the 1.75-inch 8K4K D-ILA device, the world’s first device to achieve real Super Hi-Vision definition level. The new device has approximately 50% higher density in its ratio of area per pixel as compared to the 1.27-inch 4K2K D-ILA device, which was originally the world’s smallest 4K device. Furthermore, the new device has achieved a video display of approximately 35 megapixels, the world’s highest pixel counts, while continuing to provide the D-ILA series’ characteristics such as “high-quality images without a distracting pixel structure”, “high light availability”, and “high contrast ratio”.

Sony gets dethroned….JVC joins the 4K Projection club

datePosted on 14:46, November 25th, 2007 by Many Ayromlou

If you’ve been tuned into Digital Cinema Projection for the past couple of years, you’d know that when it comes to 4K projection (4Kx2K image), sony’s SXRD series was pretty much the only game in town. DLP is limited to 2K and most of the projectors out there (Christie, Barco, NEC) are all 2K projectors. A downside of Sony’s projector is that although it is as hefty as a small car it only has a 2000:1 contrast ratio (measured less than that calibrated). Its rated aggresively for 40ft screens which is not nearly big enough for true cinema applications.

That was true until JVC announced their 1.27-inch 4Kx2K D-ILA (Direct-drive Image Light Amplifier) chip at InfoComm 2007. The chip can produce a 4096×2400 pixel image with a 20,000:1 contrast ratio. That’s nearly 10x the contrast ratio of the Sony behemoth.

It measures 660 x 827 x 340 mm and is slated for launch in the first half of 2008.
