Audio Related Electronics Projects

If you’ve 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 here’s a list of some interesting audio 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.

Sound Pressure Meter: This circuit 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 will produce the same volume at your favorite chair.

· A pocket sized headphone amplifier. This project shows how to fit a amplifier circuit inside a peppermint tin to soup up the sound for your headphones.

· 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.

· Speech Amplifier/Loudspeaker. A compact amplifier/loudspeaker powered by a 6 volt battery pack to make sure you are heard, here’s the circuit and some details.

· 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 circuit and some details.

· A 100 watt guitar amplifier. If you like the idea of building a powerful guitar amp check out this project by Rod Elliot. His project description and circuit drawings provide clear guidance in building a 100 watt guitar amplifier. However this amplifier is designed to plug into a wall outlet for power, if you are not familiar with building circuits powered by 120 volts you should not attempt this project.

· Vacuum Tube Guitar Amplifier. If you would like to build a tube based guitar amplifier look at these projects 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 this project.

· Guitar Fuzz-Box: An operational amplifier based circuit which produces a wide range of sound effects.

· 40 meter radio receiver. The circuit for a 40 meter radio receiver comes with some interesting tips that gives a glimpse of the techniques used to build a receiver from basic components.

· 75 meter ham transceiver. After you’ve got your ham license you might try this transceiver project, the author has provided some very nice photos to help you lay out the circuit.
