To answer these concerns, the challenge was put forward to fit a full fledged AV tester into a mint-tin can with minimal requirements for using it. With these ideas, requirements and desires all in mind I delved head first into the project to see how well things could come out.
Purpose & Overview of this project
For this project I want to build an Audio-Visual test box that I can plug into a standard VGA monitor and see a 800x600 display of colors (Red, Green & Blue) and the AV test box should also be able to send audio output to test speakers. Additionaly, the audio output from the AV test box should be a single tone with a knob to adjust the pitch of the tone higher and lower.
To be successful, this AV test box must work well on a variety of monitors (what good is a test box that doesn't work?). Similarly, the audio output must work across a variety of different devices, whether they are speakers, a microphone input to a laptop or audio input into a 5.1 surround sound system.
