Electronics enthusiast Jan Borsky wanted an audio mixer to modify the output from his computer speakers, and solved the problem (and more) by creating an amazing audio mixer device that could be compared to commercially-available equipment - based on the Arduino development platform. By using a TDA7439 stereo audio processor IC the mixer can can control bass, treble, volume, gain, attenuation and more. The system also includes surround processors, full digital channel switching, a VU meter and a friendly user interface with LCD module.
Not a project for the total beginner, however it's a fantastic demonstration of what is possible - and Jan has also published the design files so you can recreate your own. So visit the project page for a great read and more. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
If you found the project above interesting - but not sure how to start with Arduino - then the best way to learn is with our Experimenter's Kit for Arduino:
The package includes a wide variety of parts, sensors and modules including: a servo motor, lights, buttons, switches, sound, sensors, breadboard, wires and more. Furthermore a Freetronics Eleven Arduino-compatible board is included to make this an extensive hobby experimenter, inventor and starter kit. However we don't leave you alone to figure it all out, included is a great project and instruction booklet, plus access to a supporting web page and software examples. In other words - this is everything you need to get started for a fun range of electronics and Arduino related projects!
