16Miguel Sanchez | Build a Digital Video RecorderAfter learning that personal video recorders (PVR) weren't available in Spain, Miguel decided to build his own. To do so, he compiled some useful information about building a system with Linux and a DVB-S digital satellite receiver card. Read on to learn more about the hardware and software you'll need to get the job done.Download: Sanchez174.zip |
20David Smith | HTML Microcontroller-Based Nitrox AnalyzerMany scuba divers prefer to breathe Nitrox instead of regular air when they dive. To do so safely, they must use a special analyzer to measure the percentage of oxygen in the tank. David recently designed his own AT90S4433-based Nitrox analyzer.Download: Smith174.zip |
28Bob Armstrong | Artificial Life DisplayPart 2: ConstructionLast month Bob described how his artificial life display simulates a cellular automaton designed in 1970. Now it's time to learn how he assembled the system and brought it to life.Download: Armstrong174.zip |
36Brad Stewart | Z8 Encore!-Based Audio ProcessorRather than shell out big bucks for a karaoke and audio effects processor, Brad hit the work-bench and built a programmable Z8 Encore!-based system from scratch. Fortunately, he took copious notes as he assembled the hardware and wrote the code. In this article, he walks you step by step through each phase of the design process.Download: Stewart174.zip |
44Warren MacEvoy Dan Stadelman | PC-Controlled RC DeviceWarren and Dan recently reverse engineered an RC transmitter, connected the transmitter to a PC, and wrote control software. The result is a platform from which you can build and control everything from simple RC car designs to complex artificial intelligence systems.Download: Stadelman_MacEvoy174.zip |
52Shlomo Engelberg Jonathan Garzon Naor Afgin | Signal Processing with the ADuC812Digital signal processor chips can be hard to understand. They also tend to be peripheral-poor, so if you want to use one in a signal processing application, you have to add peripherals. Shlomo, Jonathan, and Naor have an alternative: signal processing with a peripheral-rich ADuC812 microconverter.Download: Engelberg174.zip |
56Olin Lathrop | Digitally Control Power Factor CorrectionLooking for an affordable way to control switching power supplies and power factor correction? Olin's got the solution. Replacing analog control electronics with digital processing power creates the possibility for new control schemes. For instance, you can use a digital processor to implement new algorithms like the PFC algorithm Olin describes in this article.Download: lathrop174.zip |
From the Bench68Jeff Bachiochi | HTML Light-to-Frequency ConversionPart 2: Pulse and Oxygen ContentLast month, Jeff showed you how to use a TAOS TSL230R light-to-frequency converter. In this column he describes a TSL230R-based device that allows you to monitor a heart rate.Download: Bachiochi174.zip |
