A Collection of Electronic Projects and Circuits
If youíve already worked through a few projects from Electronics Projects For Dummies and caught the electronics bug you might want to try a few projects from other sources. To help you out hereís a list of some interesting projects that Iíve found around the Web. These projects look interesting and are well documented but we havenít had a chance to build them all, so results may vary! Some of these projects use high voltages and currents we make no warranty as to their safety, it is your own responsibility to only tackle projects that you have the knowledge and skills to work on safely.
∑ Plant Moisture Meter. This circuit takes the guesswork out of watering plants by lighting up an LED when the soil is dry.
∑ Analog Sound Synthesizer. This very well detailed project write-up on the Music from Outer Space Web site shows how to build a analog sound synthesizer.
∑ 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, hereís the circuit and some details.
∑ Circuit for High Speed Photography. Would you like to take photos of split-second events such as the momentary splash when you drop a crouton in a bowl of soup? This circuit by Matthew Swann triggers your cameraís flash after the crouton, or other object passes through an IR beam.
∑ A pocket sized LED display that lights up to music. This project 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.

Datasheets: The Key to Reading Schematics
Youíve found the schematic online for a cool electronic project that youíre eager to build. However, not all project information you find online is created equal. Sometimes youíll 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 doesnít come with a clear explanation of how the circuit works, you can use datasheets to fill in the missing information. ........link to full article
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 youíre like us, sometimes you go to a large discount store for bargain bulk groceries; other times, youíre off to a corner store because itís convenient or to a gourmet shop for a special (but expensive) treat. So how do you choose what electronics supplier to go to? ... link to full article
