Electronics Projects - Electronic Circuits
If you've already worked through a few projects from my books;
Electronics Projects For Dummies
Complete Electronics Self Teaching Guide
and caught the electronics bug you might want to try a few projects from
other sources. To help you out here's a list of some interesting
electronics projects that we've found around the Web . These projects
look interesting and are well documented but we haven't had a chance to
build them all, so results may vary! We've also included links to other
Web sites that contain projects you can browse through. We make no
warranty as to the safety of these projects, only tackle projects that
you have the knowledge and skills to work on safely.
Electric Wire Locator: This
by Charles Wenzel can be used to locate electric wires in walls, it
may be useful when remodeling. Let me know how accurate it is.
on the TechDesign Electronics Web site uses the PIC 18F452
microcontroller, pressure, temperature, and humidity sensors along with
radio transmitter and receiver modules to allow you to monitor the
Running Message Display:
on the Electronics Zone Website shows how to use LEDs to light up a
message, such as WELCOME, one letter at a time. When the whole message
is alight the message goes dark and starts up again with the first
Color Sensor. This
on the Electronics Zone Web site shows how to use of optical filters and
light dependant resistors together to drive electronic circuitry that
lights a LED corresponding to which one of five different colors of
light is present. While I can't think of a practical use it's a nice
demonstration of mixing optics and electronics.
Plant Moisture Meter: This
takes the guesswork out of watering plants by lighting up an LED when
the soil is dry.
Clap Activated Remote Control: This interesting
on the Electronics Zone Web site allows you to build a remote
control activated by clapping your hands.
Rain Detector: This
project by Charles Wenzel activates a buzzer to let you know
that its starting to rain so you can cover up items in your yard.
Sound Pressure Meter: This
on the Red Circuits Web site is used to calibrate the sound output of
each speaker in your sound or home theater system so that they all have
produce the same volume at your favorite chair.
Guitar Fuzz-Box: An operational amplifier based
which produces a wide range of sound effects.
Pocket sized LED display that lights up to music:
on the Electronic Peasant Website shows how you can create three spirals
made up of LED's that light up to different frequencies of music. The
components all fit into a shape compact enough to clip onto your pocket,
if you like to dance with lights this could be a neat effect.
Pocket sized headphone amplifier: This project shows
how to fit a amplifier
inside a peppermint tin to soup up the sound for your headphones.
A robot that walks toward bright lights: Try this
type walking robot with a few added features.
Speech Amplifier/Loudspeaker. A compact
amplifier/loudspeaker powered by a 6 volt battery pack to make sure you
are heard, here's the
and some details.
Vacuum Tube Guitar Amplifier: If you would like to
build a tube based guitar amplifier look at these
on the Cooperative Tube Guitar Amp Project web site. Make sure your have
the knowledge and skills to work with high voltage before you tackle
Battery Powered Guitar Practice Amplifier. Want to
practice your guitar playing somewhere without power? The Ruby amplifier
is designed to work on a nine volt battery pack, here's the
and some details.
A wireless scarecrow: This
by Charles Wenzel detects footsteps of a deer or other creature and
sounds an alarm to scare them away from your vegetable patch. I
especially like the way he shows you how to protect the circuit from bad
40 meter radio receiver: The circuit for a 40 meter
receiver comes with some interesting tips that gives a
glimpse of the techniques used to build a receiver from basic
A refrigerator door alarm. Here's a
by Charles Wenzel that sounds an alarm when the refrigerator door stays
open longer than the time you preset. A great way to stop your cat from
getting in the refrigerator if you forget to close the door.
