Build
a Digital Video Recorder
Miguel
Sanchez
After
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. p. 16

Microcontroller-Based
Nitrox Analyzer

|
Read
it now!
by David Smith
Many 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.

Artifical
Life Display (Part 2): Construction
Bob
Armstrong
Last
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. p. 28
Keywords:
Life game, LED, construction, 89C51xxx, programming,
power supply, remote control, IR, DS275, MAX7219

Z8
Encore!-Based Audio Processor
Brad
Stewart
Rather
than shell out big bucks for a karaoke and audio
effects processor, Brad hit the workbench 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. p. 36
Keywords:
Audio processing, Z8 Encore!, karaoke, TA2011,
PWM, ADC, echo, reverberation, pitch shifting, TS972

PC-Controlled
RC Device
Warren
MacEvoy & Dan Stadelman
Warren
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.

Signal
Processing with the ADuC812
Shlomo
Engelberg, Jonathan Garzon, & Naor Afgin
Digital
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. p.

Keywords:
Signal processing, ADuC812, filtering, digital,
MATLAB

Digital
Control Power Factor Correction
Olin
Lathrop
Looking
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.
p. 56
Keywords:
Power factor correction, digital, switching
power supply, filter, isolation, dsPIC30F2010, regulation,
ADC
