24Devlin Gualtieri | Improving Microprocessor AudioDigital circuitry and square waves are not always the best methods of producing audio alert signals. Analog circuitry and sine waves are another option. This article provides some simple techniques for generating high-quality sine waves without excessive filtering. |
28Walter Krawec | Experiments in Developmental RoboticsPart 2: Robot Reflex and Instinct SystemsThe first part of this article series introduced artificial neural networks, described an evolving neural network used in a robot development project, and explained how a short-term memory system evaluates a network. Part 2 explains how to add data to a short-term memory system and discusses how a robot is equipped with minimalistic "instincts" and "reflexes," which are used by the evolving neural network to guide its evolution.Download: 279-Krawec.zip |
34Graig Pearen | Solar Array TrackerPart 1: SunSeeker HardwareThe SunSeeker system tracks, monitors, and adjusts solar photovoltaic (PV) arrays based on weather and atmospheric conditions. It identifies conditions, measures PV and air temperature, compiles statistics, and communicates with a local server that enables software algorithm development and refinement. Diagnostic software monitors the design's motors to show both movement and position.Download: 279-Pearen.zip |
Programmable Logic in Practice46Colin O'Flynn | Using Internal Logic Analyzers for FPGAsSometimes you need to debug an FPGA design in a physical device. Many integrated logic analyzer tools enable you to probe signals inside a running design. This article introduces integrated logic analyzer tools and shows you several tips for a more enjoyable debugging experience. |
The Darker Side52Robert Lacoste | Bipolar Transistor BiasingBipolar junction transistors (BJTs) are not a new technology, but they can be a useful tool in many designs. For example, you can use an inexpensive BJT to build an amplifier. This article explains how.Download: 279-Lacoste.zip |
The Consummate Engineer58George Novacek | Battery BasicsPart 2: Battery Back-Up PowerA rechargeable battery's life cycle depends on whether it has been properly charged. This article describes how to construct a floating back-up power source with a lead-acid battery and a charger.Download: 279-Novacek.zip |
