(and two iPads if you're so inclined...)
Step 1: Parts List
-Audio sources (whatever it is you want to mix)
-1/8” Audio cables
-Speaker or headphones
-Regular graphite pencil
-Electrical tape (optional, but recommended)
-1 or 2 y-split cables (optional, for stereo)
Step 2: MAKING THE MIXER
Fill in the shape with a graphite pencil. Make sure to press hard and apply several layers. The graphite must be thick enough and continuous in order to carry an electrical current.
Step 3: WIRING THE MIXER
Connect an alligator clip to the end of your mixer. Connect the other end of the clip to the tip of the audio cable connected to the speaker (or the tip of your headphone’s audio jack).
Connect the sleeve of the speaker cable to the ground of your mixing cables. In our example, these are the y-split cables.
You must also make sure all mixing cables share common ground. Do this by connecting the sleeves of each cable with a wire. It is recommended that you secure bulky cables in place with tape, otherwise they could fall and rip apart your connections. Secure the connection with electrical tape. Plug the 1/8” end of your y-splitters (or whichever cable you are using) into your device.
