[ANN] AVRcam: Real-time image processing engine based on the AVR

Hi All,I thought I would pass along some information on my latest project: the AVRcam. The AVRcam is a small, low-cost, image processing enginebased on the Atmel mega8 microcontroller. The AVRcam provides thefollowing capabilities: * Track 8 different objects of 8 different user-defined colors at 27 frames/sec * Provide real-time tracked object statistics (color, bounding box, center of object, and more) through a standard serial port (UART) * Tracked image resolution of up to 88 x 144 (at 27 frames/sec) * Low power consumption (the ENTIRE system draws 5V at only 53 mA running at full speed) * Small size (Experimental Version with breadboard area: 3.5" x 3.1" Final Version: 2.3" x 2.0") * In-circuit programmability for expanding its capabilities In addition, a PC application called AVRcamVIEW supports the AVRcam,allowing the user to test and calibrate the AVRcam. AVRcamVIEWprovides the following: * Take full-color snapshots (176 x 144 pixels) with the system and display the images (both raw Bayer data and interpolated data) * Easily create a Color Map of colors to track based on a snapshot (just click on the colors of interest and add them to the Color Map) * Adjust the precision of each tracked color (i.e. provide a range of acceptable R-G-B values for each color), allowing the user to adjust the Color Map to the available lighting conditions * Display the real-time tracking results of each tracked object (with color and bounding box information) * Record a tracking session for playback at a later time * Test the system out in any OS supported by Java 1.4 (Windows, Linux, Macintosh, etc.) You can find out more about the AVRcam at: clicking on the AVRcam link (there are also links to some of myother robot projects here...you'll have to forgive my "basic"website...I'm just starting to figure out this HTML stuff ;-)I'm continuing development on the project, but wanted to get the...

: The ATmega8 has 8K of flash and 1K of SRAM. Still impressive, though. : 27 frames per second is about as fast as a human perceives the world.

. . And if that isn't enough, the Mega16 is (if I remmber correctly) pin compatible and doubles the amount of flash.

I think you are thinking of the ATmega168 - pin compatible with the ATmega8, but with 16K FLASH and a host of other neat goodies, not to mention that it can clock at 20 MHz for a nice speed boost even over the already speedy 16 MHz. In actual instruction execution, this clock speeds translate to roughly 20 MIPS and 16 MIPS respectively.

The ATmega16 is a 40 pin DIP, if I recall.

I have the equipment to make 2 sided PCB's. plotter, dip tanks, cnc drill press.

This could be a good time for me to figure out how to convert popular CAD PCB formats into the format my CAD program uses.
