Brian Senese

Get Cooking with Embedded Linux

You can use Linux for a wide range of embedded projects. For instance, Brian developed a Linux-based system that can store his favorite recipes and display them on a small LCD screen. Now he can access his recipes without opening a cookbook.



Steve Ciarcia

Solar-Powering the Circuit Cellar

Part 2: From the Ground Up

Last month, Steve began describing the process of installing his solar PV system. This month, he covers the massive task of preparing two 11' schedule 80 poles (8" in diameter) to support two of the three solar arrays. As you'll see, it's easier said than done. The technical adventure continues!


Richard Hoptroff

Cash for Code

Part 1: A Focus on Firmware

Ever dream of becoming a firmware mogul? In the first part of this series, Richard looks at the potential for firmware to become an industry in its own right. He then describes what a product offering would have to look like in order for it to succeed in the marketplace.


Michael Griebling

Precision Oscillator Calibrator

Michael built a precision oscillator calibrator that quickly and accurately measures low frequencies. The system can communicate with a host computer, perform initial frequency and calibration set up, and display measured oscillator errors.



Ben Smith

Build a Learning Remote Control

You use an infrared (IR) remote control every day, but do you know how the technology works? Ben covers the topic of IR communication and describes a simple MAXQ2000-based remote control design.


Lessons from the Trenches


George Martin

George Martin

You need the right tools and procedures to make writing and debugging code as easy as possible. This month, George takes a break from his C language tutorial series to cover some tools that you should consider adding to your arsenal.


Monte Dalrymple

Designing for Hostile Environments

Monte recently designed a CPU that will one day orbit Jupiter in one of the most hostile environments in the solar system. In this article, he describes design techniques that you can use to prepare your systems for operation in hostile environments.

Special Feature


Ed Nisley

That Was Then, This Is Now

This month marks Circuit Cellar's 20th anniversary. Ed reminds us that even though embedded technology has come a long way since 1988, what's inside the box still counts. Electronics really is better today!

From the Bench


Jeff Bachiochi

Portable Poll Server

Part 1: System Setup

Jeff explains how to design a microcontroller-based polling system that can be attached to a LAN and used to feed web pages to a browser. Each page includes a question and possible answers. When a user is finished, the results can be displayed on a PC. Ask and you shall receive.


Silicon Update


Tom Cantrell

The Quad Squad

Need some flash? Call on the "Quad Squad" when you need a lot of flash memory but don't have too many pins to spare. Tom introduces Winbond's new family of Quad I/O spiFlash parts.
