8 John Gorsky	New Product News DAQe-2208 96-channel, 12-bit, 3-Msps, PCIe DAQ card from ADLINK Technlogly, Inc. AnadigmFilter1 dpASP chipset from Anadigm, Inc. SIFI-F (B84111FM*) series of two-line EMC filters from EPCOS, Inc.
10 Brian Felder	Signal Recovery Restore the Attenuated Portion of an AC-Coupled Signal Brian developed an algorithm for a digital filter that restores the attenuated portion of an AC-coupled signal. A digital storage oscilloscope captures the waveform and data is passed through the digital filter. The result is the original signal without the DC portion. Download: Felder-207.zip
18 Darryl Uchitil	Wireless Thermostat System Darryl designed a wireless zone thermostat system that can remotely read the temperature, calculate the dew point, and force a setback. This easy-to-implement design is perfect for the home or office. Download: Uchitil-207.zip
26 Thomas Black	The Monarch Butterfly Build a Barometric Altimeter The Monarch is a compact, easy-to-use barometric altimeter. The ATmega169-based system is used for the barometric sensing of air pressure, digital temperature sensing, and RC servo pulse decoding. Download: Black-207.zip
35 Aubrey Kagan	Resilience in Embedded Designs Part 2: RS-485, Voltage Supervisors, Watchdogs, & Outputs Last month, Aubrey described how you can protect your designs' inputs so they can endure under the worst conditions.This month, he covers RS-485, resilient outputs, and watchdogs. Keep your designs protected! Download: Kagan-207.zip
40 Ken Merk	Simple Ethernet You can use a picoFlash SBC with an Ethernet controller to send embedded Ethernet between master and slave nodes. The easy-to-use system makes writing software packets and debugging a cinch. Download: Merk-207.zip
46 Nicusor Birsan Ionut Tarsa	Embedded Speech Speech Synthesis for Small Applications It's time to try your hand at an embedded speech application. In this article, Nicusor and Ionut introduce you to speech synthesis technology and describe how to bring audio capabilities to small embedded applications. Download: Birsan-207.zip
Above the Ground Plane 55 Ed Nisley	Hearing Clearly Hardware In his last column, Ed covered his hearing booster's design. This month he focuses on the actual circuit board and its limitations. Download: Nisley-207.zip
From the Bench 60 Jeff Bachiochi	RoboGrowth Jeff attended the recent RoboBusiness Conference and Expo in Boston. This month, he presents everything you need to know about this year's crop of promising robotics technologies.
The Darker Side 70 Robert Lacoste	No Fear with FIR Put a FIR Filter to Work Working with finite impulse response (FIR) filters isn't black magic. Robert covers the basics and touches on the mathematical concepts you'll need to understand in order to put a FIR filter to work. Download: Lacoste-207.zip
Silicon Update 80 Tom Cantrell	I Sense, Therefore I Am As Tom has said in the past, "Sensors are as key to embedded control applications as the controllers themselves." Read on to learn about the hot new sensor technologies that he encountered at the 2007 Sensors Expo in Chicago.
