Epicenter Web Server Statistics
The web site transition is just about complete. The plots below show the sections of the web site that are more popular. I’ve also included a plot of the web browsers that are most frequently used. It looks like most of the major search engines have indexed the site now. I’ll be shutting down the EpicenterTech.biz domain at the end of September.


Dual 16-Bit, 160 MSPS Pipelined ADC!
The ADC16DV160 is a monolithic dual channel high performance CMOS analog-to-digital converter capable of converting analog input signals into 16-bit digital words at rates up to 160 Mega Samples Per Second (MSPS). This converter uses a differential, pipelined architecture with digital error correction and an on-chip sample-and-hold circuit to minimize power consumption and external component count while providing excellent dynamic performance. Automatic power-up calibration enables excellent dynamic performance and reduces part-to-part variation, and the ADC16DV160 can be re-calibrated at any time through the 3-wire Serial Peripheral Interface (SPI). An integrated low noise and stable voltage reference and differential reference buffer amplifier eases board level design. The on-chip duty cycle stabilizer with low additive jitter allows a wide range of input clock duty cycles without compromising dynamic performance. A unique sample-and-hold stage yields a full-power bandwidth of 1.4 GHz. The interface between the ADC16DV160 and a receiver block can be easily verified and optimized via fixed pattern generation and output clock position features. The digital data is provided via dual data rate LVDS outputs – making possible the 68-pin, 10 mm x 10 mm LLP package. The ADC16DV160 operates on dual power supplies of +1.8V and +3.0V with a power-down feature to reduce power consumption to very low levels while allowing fast recovery to full operation.

Inside the SheevaPlug
Here’s a link to a web site that shows the internals of the SheevaPlug. Thanks to Rober Wittig for the link reference! My SheevaPlug should be here on Monday so stay tuned for more photos and info.
The SheevaPlug Internals
The SheevaPlug - Computing power in a small package!
This is a SheevaPlug. It’s an embedded computing development platform that can run several operating systems. I’m planning to install Ubuntu Linux and the latest Java SDK on my system and will use it as an application and database server for some iPhone applications that I have in mind. I purchased a 32 Gb SD card to use as primary storage. The system also has 500 Mb of RAM and 500 Mb of FLASH memory. It has a 1.2 Ghz ARM processor so you could also run Google Android on it. You can find more info at the SheevaPlug Wikipedia page. I’m still waiting for my unit to ship, lead times are 4-6 weeks in the US now. I’ll add more photos and videos here once I have my system prepped and running. Stay tuned!

Arduino Mega Development Board
Here’s a photo of the Arduino Mega development board. I have one in the lab now and have downloaded the development tools for the Mac and Linux platforms. You’ll notice that there are analog and digital ports, PWMs, and four serial port communications channels. With a little research you’ll find a wide range of daughter cards that plug into the header pins. These boards are called “shields”. Check out YouTube and Wikipedia for additional reference information on the board.

Getting down to some hardware hacking!
Sorry for not posting in a while but I’ve been busy with a Ztar project and I’ve been looking at various platforms for developing embedded systems and servers. I’ll be adding links to the forum as I move forward with the evaluations. You will notice that I’ve added sections for the Arduino Mega board, the Beagle Board, and the SheevaPlug. I have the Arduino Mega and the Beagle Board in house now but the SheevaPlug is on back order so I don’t expect to see it for 6-8 weeks. I’m planning to test the Beagle board running Ubuntu for ARM and Google Android. I’ll most likely use Bluetooth or WiFi for a network connection assuming I can find the appropriate drivers. I’ll be using my ASUS EeePC as the main development platform. It has a SD memory card slot so I can easily configure my 32 Gb SD card and then use it to boot the Beagle board. I also picked up a FT232R USB to serial converter module and a 24 channel MIDI controller from Hale Microelectronics.
All of these boards will be combined to create a Java based 3D multimedia platform for virtual world applications (VRMAD). I’ve been working on this project on and off for several years, moving forward as I could afford to buy the boards and test equipment. I tried to go the VC route without success so I’ve decided to boot-strap the development myself. At this point, I’m ready to connect all the boards into a prototype system so I can continue the hardware and software development work. Keep on eye on the site for more photos as the project progresses!
Guess that’s it for now. Time to go work on some Ztar code....

Epicenter Technical Forums - New Format
The Yabb forums have been removed because I am tired of waging a constant battle with spammers and hackers. I’ll continue to post items of interest here but it will no longer be an open forum. More to come later....
