EE 210 Audio Mixer Case

thingiverse

This is a case I designed for the audio mixer made in EE 210 at Penn State. The 9V batteries are placed in the lower half of the case and the PCB in the upper half. You will need to wire your power leads out of the bottom of the PCB instead of the top for them to fit. Keep in mind that the LEDs and op-amps are always drawing power when the batteries are connected with how the professor designed the circuit. I may rework this case later to include a power switch to fix this problem but it depends if I can find a good way. The karaoke switch is also hard to reach with the current design, and I may come back to that too.
