Altoids Tin Audio Mixer

Introduction: Altoids Tin Audio Mixer

About: I have always loved woodworking and inventing. I will try to post an instructable about everything that I think is good. Visit my website to see instruction videos about home improvements with general contra...

I had wanted a small audio mixer for a long time but they were to expensive so I built my own. I only put a volume control on two of the four imputs but you can add them to the other two or the output if you want.

    Would the output then have to be sent to an amplifier to be heard over speakers? I'm new at all this so thanks for any help.

    The wiring diagram could use a little help. Each potentiometer has 3 terminals. The common way to wire it would take the input lead to the right terminal, the output lead to the center terminal, and ground (green on your diagram) to the left terminal. (As viewed from the top of the box).

    Do you have any tips on drilling clean holes for the jacks in that thin metal?

    cut out a block of wood that fits snugly in the tin, then use that to drill into

    you can fill your can with water and freeze it then drill your holes through the ice

    Sorry, I didnt spend a lot of time on the diagram, it probably should have a lot more detail. I have some pictures of the inside of my mixer, I will upload them as soon as I can.
    To make clean holes I punched a hole in the tin with an awl then used a small drill bit and slowly worked my way up to the correct size, the holes will not be perfect but any rough edges should be covered with the nut that holds the audio jacks in place. (Do not push too hard when you are punching or drilling the holes to avoid denting the tin, if you put a piece of wood in the tin before you drill the holes it will help)

    Would it be possible to use this to mix the input of multiple computer microphones? Maybe by using smaller resistors and hooking the output to an amp or computer for recording?
