AVRCam:
A Low-Cost Embedded Vision System
John
Orlando
The
AVRcam is a low-cost image-processing engine. The
system shows great promise for robotics applications,
as well as motion detection and object recognition.

Read
it now!
by Bruce Pride
Simple data acquisition is only a project away. Bruce shows you
how to build a simple data acquisition device
around an LPC2138. The system features a simple
GUI that allows you to view graphed data instead
of the streaming serial data in a terminal
emulator session. p.

Three-Axis
Stepper Motor Controller (Part 1): Design Basics
Viraj
Bhanage, Prajakta Deshpande, & Praveen Deshpande
Technicians
in high-tech laser laboratories use optical components
such as lenses, mirrors, and filters to direct laser
output. A multiple-axis stepper motor controller
gives technicians greater control over the components.
Special firmware enables remote control from a PC.
