A Collection of Electronic Projects and Circuits
If you've already worked through a few projects from my books and
caught the electronics bug you might want to try a few circuits from
other sources. To help you out here's a list of some interesting
electronics circuits that we've found around the Web . These circuits
look interesting and are well documented but we haven't had a chance to
build them all, so results may vary! We make no warranty as to the
safety of these circuits, only tackle projects that you have the
knowledge and skills to work on safely.
Just A Minute.

game. The first one to tap their button rings a buzzer and gets to
answer the question.
Turning Gadgets On with a Wave of Your Hand. This
circuit by Dave Johnson compares the signals from two photodiodes using
a comparator chip. When you pass your hand over the photodiodes the
output of the comparator chip goes high, turning on a transistor which
Dave uses to power a buzzer in his
Clap Activated Remote Control: This interesting

activated by clapping your hands.

Datasheets: The Key to Reading Schematics
You've found the schematic online for a cool electronic project that
you're eager to build. However, not all project information you find
online is created equal. Sometimes you'll get great descriptions of what
the project does and how the circuit functions, and sometimes you just
get a schematic with component values that leaves you scratching your
head over how everything comes together. If a schematic doesn't come
with a clear explanation of how the circuit works, you can use
datasheets to fill in the missing information. ........link

Soldering Surface Mount Components
Instead of dual in-line packages (DIP) that are easy for a hobbyist
to use, many new components are produced only in surface mount packages
because circuit board manufacturers prefer them for use on their high
volume assembly lines. ...link to full article
When Is a Supplier Right for You?
If you're like us, sometimes you go to a large discount store for
bargain bulk groceries; other times, you're off to a corner store
because it's convenient or to a gourmet shop for a special (but
expensive) treat. So how do you choose what electronics supplier to go
