Timer Development

From Timing Cycles to System Programming

Need a stand-alone timer or a timepiece for a large application? Read on to learn how to develop the right timer design to suit your needs. It's time to put your hardware and programming skills to good use.



Carlo Tauraso

Very Low-Frequency Datalogger

If you're interested in radio emissions, you can build a very low-frequency (VLF) datalogger at your workbench. This PIC18LF4620-based design features a 16-bit datalogger, an SD card for data storage, a customizable hexagonal loop antenna, and circuit-controlled battery power.



Kevin Gorga

Cable Tracer Design

Part 2: Software and System Control

In the first part of this series, Kevin presented his innovative Cable Tracer project, which is used to detecct underground cables. In this article, he covers the software and explains how to operate the design.

Get Started with Embedded Development

Part 2: Coding from Start to Finish

Now that you're familiar with ARM Cortex-M3 microcontrollers, it's time to take a close look at the application development process. This article covers the coding process from start to finish.


Silicon Update


Tom Cantrell

Neural Networker

A SNAP-Shot from Synapse Wireless

When it comes to embedded wireless, the good news is that there are plenty of alternatives to choose from. The bad news is that too many complicated options can lead to paralysis by analysis. This month Tom looks at a solution that puts all the answers -- including the radio, protocol, and tools -- on a little bit of silicon.


Brian Millier

Smart Power Bar

Simple Circuitry Enables Energy Conservation

In-home energy conservation is just a project away. Power bars are used to turn off several electronic devices at the same time. Brian recently designed his own to meet his needs. The compact design consists of a conventional 60-Hz power supply, an MCU, a relay and an IR module.
