Build an Inexpensive Temperature-Testing Chamber

Most home laboratories lack sufficient temperature-testing technology, which means kitchen ovens and refrigerators find use as heating and cooling systems for PCBs. Steve's home lab had been no different until he built his own benchtop temperature chamber.

George Novacek

Fault-Tolerant Electronic Systems

There's no escaping it: sooner or later, all electronic systems fail. As a designer of embedded systems, how can you prepare for system failures? Is there a way to plan for the unforeseen glitches? George's article is a must-read for anyone with an electronic system in the pipeline.

Single-Pin Analog-to-Digital Conversion Techniques

Picture this: you need to add an analog input to a design, but you have only one digital I/O pin remaining. This month, Ingo presents an intelligent, cost-effective solution.


Dick Cappels

Microcontroller-Based Digital Lock-In Milliohmmeter

A milliohmmeter is a handy tool for tasks like measuring a switch's contact resistance and checking the trace resistance on a PCB. Dick built his own microcontroller-based digital milliohmmeter using lock-in amplifier topology. The project is simple as long as you follow Dick's instructions. Get ready to improve analog performance with a microcontroller.

Tracing Current and Voltage

Design a Unique PC Sound Card Curve Tracer

George has come up with a new method for obtaining the I-V curves of two- and three-terminal devices. Following his lead, you'll be able to plot the I-V characteristics of diodes and transistors. If you have a PC and a Windows-compatible sound card, you're well on your way to being able to trace current and voltage from your workbench.

M. Tim Jones

GNU Development

Flexibility in software design is essential in many situations. That's why Tim likes working with the GNU compiler toolchain. It gives him the freedom of choice. This month, he gives us a guided tour of the GCC.

Global XPortation, Harness the Power of the 'Net with the XPort Server

With Lantronix's XPort embedded device server, you can Internet-enable embedded products without wasting too much time, money, and design space. This month, Jeff shows you how he used the XPort to allow a Java-enabled browser to communicate with a thermostat. Offsite temperature control just got a whole lot easier.


Tom Cantrell

Silicon Update

Hot Chips 15

Last summer's Hot Chips conference at Stanford University was the coming-out party for many of the industry's newest high-end chips. As usual, Tom was in attendance, doing the rounds and taking copious notes at all of the meetings and presentations. This month, he provides a glimpse of the high-end silicon that will drive your future designs.
