EPE
PIC® World ClockOur latest PIC®-powered project, this time-zone clock offers global time zone data, a calendar and position of the sun, all neatly displayed on a graphics LCD display. Uses a PIC® 16F877 with EPE's free source code, available for download from our FTP site.
Teach-In
2002 (Part 10) - Advanced Sensors and Telemetry Systems. Our marathon series outlining the use of environmental sensors in test and instrumentation applications concludes with a look at telemetry systems: methods of transmitting data from remote sensors. We suggest a remote anemometer and how to transmit analogue signals as well. Have you checked out the previous nine parts of this series as well?
"Big
Ears" Binaural Buggy
A sound activated mobile buggy that follows your voice. This
stereoscopically-sensitive critter uses twin electret microphones and
d.c.motors to pinpoint a sound source, eg. a handclap. Full details of
the constructional buggy are included.
Simple
Audio Circuits (Part 4) - concluding part of this top-quality series examines loudspeaker enclosures and associated set-up circuits. If loudspeaker design "baffles" you, then this in-depth article will help you to "horn" your skills! A tuneable oscillator circuit is also described.
Pickpocket
Alarm- dodge those artful pickpockets with our simple portable alarm. Compact battery-powered system uses a magnetic switch and tilt-switch to warn of attempts to steal a handbag. Ideal project for beginners.
Special Feature: Evolutionary Electronics - looking into the world of evolving electronics, the Genetic Algorithm, artificial intelligence and more. Also in this issue - Ingenuity Unlimited- readers' own circuits; Circuit Surgery - Mini Siren, transformer sizes, high-bri LEDs; Using Square Roots with PIC® microcontrollers; Interface - Using MSCOMM to receive serial data on your PC.
