20Nelson Epp | RIP-Roaring FunRotational Inverted Pendulum DesignRotational inverted pendulums (RIPs) help test nonlinear control theory. This article explains how to use hardware and control algorithms to design a RIP that you can activate and control using a TV infrared remote.Download: 272-Epp.zip |
28Bruce Land | Markov Music BoxBuild a Microcontroller-Based Music DeviceYou can build a music device with an 8-bit microcontroller that enables you to change the device's note sequence, timbre, tempo, and beat. The design uses the Markov process to sequence the notes and frequency modulation to enrich the sound. |
34Dean Boman | Energy Monitoring SystemThis energy monitoring system provides real-time home electrical usage monitoring to help you make informed energy usage decisions. The system hosts a web server that provides a webpage with your current energy usage on a circuit-by-circuit basis. In addition, the system interfaces with your home automation system for long-term monitoring and logging.Download: 272-Bowman.zip |
Questions & Answers41Nan Price | Problem Solving, Programming, and PSoC-Based DesignAn Interview with Chris PaianoChris Paiano is a problem solver and fast learner. His father introduced him to programming at an early age, and Chris has continued to team with his father writing software and firmware for some of his hardware designs. Chris has written dozens of unique application notes for the Cypress Programmable-System-on-Chip (PSoC) chipset. He is currently using PSoC in an innovative household project and dreams of finishing his concept for environmentally friendly electric/hybrid vehicle wheel-drive retrofit kits. |
Embedded Security45Patrick Schaumont | Chip BiometricsDigital chips have biometrics, just like humans. Chip biometrics -- or fingerprints -- are unique features that distinguish one chip from another of the same type. This article describes how a fingerprint can be extracted from a field programmable gate array (FPGA) and used in an authentication protocol to test a chip's identity.Download: 272-Schaumont.zip |
The Consummate Engineer52George Novacek | Quality and Reliability in DesignProduct quality and reliability go hand in hand. This article examines causes of field failures, their distribution, and methods to reduce them. |
Above the Ground Plane56Ed Nisley | Arduino Survival GuideAnalog I/OThe analog inputs and outputs on Arduino microcontroller boards can connect directly to real-world sensors and actuators. Ed explains why the analog inputs may deliver surprising results and how to get true analog voltages from the Arduino's PWM outputs, while avoiding problems along the way. |
From the Archives62Jens Altenburg | SOPHOCLESA Solar-Powered MSP430 RobotWorried about the side effects of that presumably noxious gas that's lingering in your basement? Rather than trying to waft samples into an empty jar for your local health department to assay, try following Jens' lead by building your own gas-detecting robot. |
From the Bench68Jeff Bachiochi | Microcontroller-Based Morse CodingYou can use a development kit to design a tool for correctly transmitting Morse code. The design includes a microcontroller, I/O routines, an RS-232 interface, and an LCD.Download: 272-Bachiochi.zip |
