BatMon to the Rescue

A Battery Monitor for RC Applications

For years, hobbyists have relied on voltmeters and guesswork to monitor the storage capacity of battery packs for RC models. Now, Thomas introduces a more precise high-tech battery monitor that is small enough to be mounted in the cockpit of an RC model helicopter.

Extreme OSMC

Part 1: Open Source Motor Control Project

Whether you're a Formula One racer or commuter weaving through rush-hour traffic, speed control is a concern. Brakes alone won't suffice, so you need a motor that pitches in. With this step-by-step guide, you can tailor Sonny's OSMC project for RC cars, boats, or robots.

Behind the Scenes

Part 2: Software Control

Last month, Daniel described the design of his DIY animatronics project, which involved a controller board, motors, controllers, sensors, and a host robot. In this article, he demonstrates how his system works and how you can use it in your own animation project.



Olaf Pfeiffer

Selecting the Best CAN Controller

Selecting the right CAN controller for your specific application can be a daunting task when you consider the numerous options on the market today. Fortunately, Olaf has some great advice that can help you minimize cost and maximize performance.


Jim Turley

Starting Down the Pipeline

Part 1: Hyper-, Super-, Whatever-Pipelines

The best way to approach a project is with as much knowledge as possible. Do you know everything there is to know about microcontrollers? In Part 1 of Jim's two-part article, he teaches us a lesson about pipelines, the key ingredient in microcontrollers.

RoCK Specifications

Part 3: Behavior-Based Programming

It's easy to see why Joseph and Ben's Robot Conversion Kit was successful in the 2001 Design Contest. So far, they've covered the specifications and circuitry, and now it's time to describe the fundamentals of the module's behavior-based programming scheme.

Still Swimming With the STK500, Onto the JTAG ICE

Last month, Fred introduced us to Atmel's STK500, which is the starter kit for the company's AVR flash memory microcontrollers. This month, he tackles coding and debugging with Atmel's JTAG ICE. He's thrilled with the result, so don't miss this follow-up.

Invisible Components

What you can't see can hurt you -- at least in the analog domain. In this article, Ed flags all of the hidden obstacles you're likely to encounter on the road to building a trouble-free bicycle headlight. This project goes nicely with Ed's earlier instruction on building a taillight.

SmartMedia File Storage, Part 1: A Windows/DOS-Compatible File System

Jeff has showed us how a small PIC processor reads and writes portions of a SmartMedia memory device. This month, he shows us a project that will help you to exchange embedded data with your PC applications.

Silicon Update

FPGA Power Play

Xilinx deserves an award. Why? Well, they turned Virtex-II parts into pros. This month, Tom takes a look at the new Xilinx Virtex-II Pro FPGAs and compares it to the Virtex-II and other "super-duper" chips.
